that senator feinstein make this a priority and put pressure on the cystic departure and how the next generation system negatively has been impacting san francisco. >> thank you. >> is david lott here? i reached out to the district director. it was a very short notice. we have doing what we can. we now have the former district director as a chief of staff of mayor breathed. he was very much engaged with responding with the let -- to the letter and rating with the letter of the senator and now we will have jim lazarus, the former -- the deputy vice chair of the chamber who will be the district director for senator feinstein. he was made aware of this. we appreciate you coming out and saying a few words. >> thank you for the invitation

and holding this hearing. unfortunately, the district director could not make it but i'm here instead. again, we share the concerns of many of the residents of san francisco and we understand that this has a huge impact on the community. we are here to listen and we have also submitted a letter to f.a.a. on january 29th 2018 this year and we are continuing to hold meetings with representatives of the f.a.a. to hold them accountable and we are requesting a study to understand the impact of changing the routes, and we are very interested in hearing what the community has to say. >> thank you. i will say for the record, same thing i said to senator feinstein's office and we already know we have

congresswoman pelosi who said she is going to the mat on this issue. having the speaker be in this position and i have conveyed this to the district director and we will lead to pelosi. i know commissioner guggenheim and others have conveyed to her that this is a super big priority. it is something that would happen. the impact has been so dramatic in san francisco that it is something that we want to bring to her attention now that she is assuming this, we have very high hopes for her to be able to influence this process. did you want to say something? >> i thought you were leaning toward the microphone. okay. thank you. >> okay. i have a few questions before we wrap up. i wanted to ask if that is okay through the chair.

first question,, the f.a.a. have the authority to abolish the cystic departure and go back to preet next generation? what they have that authority to do that? >> the f.a.a. would have that authority to revert back to a prior procedure. >> okay. and what do you think, and i know it is hard for you. >> sorry to interrupt. under the context of what they are meant -- what their mandate is under modernizing of the air traffic control system, but they did that in phoenix where they did go back to a priest nexgen operation. so i believe they would have that authority. >> and the airport shut down in phoenix when they went back to that. >> no. it is still operating. >> to things keep going on and business continue?

>> yes. >> i just want to make sure. not to disguise this but i just want to understand that it is possible to make that adjustment >> i believe so. >> okay good. from your professional opinion in terms of the flight ceiling, i know there is a request from folks and we had a conversation at the roundtable about a 10,00. i know one individual commenter said no ceiling would be -- is there an appropriate level? i know when we were monitoring one dublin street, it was usually between 3,205,000-foot maximum on the departure. what is your response to the 10,000-foot request? >> what i am imagining is that it changes, it would change the departure and swing them out into the open air space just to gain altitude so they would probably take a head much closer

to oakland which would potentially cause interference with the airspace. i think i can't answer it technically with 100% degree of certainty. i am imagining that that is what it would do to that. we certainly would provide an answer from the f.a.a. on how that could be achieved and what this impacts are. i imagine that is just not doable because of the integration of the air spaces between oakland, san jose and san francisco. >> so the averages between 3,205,000 and the request would be at 10,000. what is the maximum that would be doable? >> i couldn't comment until we looked at that. there was conflicting outage -- altitudes with southbound aircraft and in the eastbound and westbound. it is an intermingling of all of

these flight tracks on different directions that have to hold different altitudes to create the separation as demanded by f.a.a.'s safety. >> what about the take offs from oakland? i'm seeing a significant increase from the takeoffs and oakland and then passing over. does the f.a.a. have the ability to could they change the flight patterns of the departures and not cross over san francisco at such a high frequency as they have over the last couple of years? >> that would all have to be woven into the potential solutions. something that we are advocating for is a combined roundtable for the region. i had a meeting 1212 weeks ago with the other directors of oakland and san jose and presented -- i am on the forum, which is a quarterly meeting with f.a.a. leadership.

to try and figure out how to reengage with the community and deal with all of the issues and hopefully create some solutions. i think our approach would be through the regional community roundtable, to help with this work among all the airports? >> i have over emphasize the abundance of riches in terms of the elected leadership. i just want to hear from your perspective. what is the role that the leadership can take in this in terms of the f.a.a. authorization? that would be part one. and it would be how the airline industry and what role they have to play. this is one of the largest hubs for united. i know united cosigned a letter with you after congresswoman spear hosted the meeting went asking for the hush at the nighttime. at least we were able to engage in that level and really appreciate the congresswoman

getting everyone's attention. but role rolled you think the elected leadership has to play along with the airline industry? it seems to be those are the most influential when it comes to the f.a.a. >> under the f.a.a. reauthorization with the studies and in particular, i talked about the noise annoyance, what i would imagine is the consequences is so dramatic in terms of public health impacted in a much different way than it is currently defined for the dbc i imagine that is why they don't see the light of day. >> and i just need to interrupt you for a second. the study you are referring to is the m.i.t. noise study? >> they are two different noise study. >> there are several different ones.

i think recognizing the consequences and dealing with the consequences in developing a program to address what comes out of the noise annoyance, that is fundamental. they have results that are very much focused on benefiting a much broader community than the 65 -- i think it redefines how a communities impacted. >> it probably lowers the decibel level. >> since this was an internal study and this was a public agency, the commit -- they commissioned the study and they have not released the study. how do we get that study released and have access to it so the public can be informed and what the best direction is to take? >> under f.a.a. authorization, they are mandated for october of 2,000 -- 2,020 -- 2020 to have a plan and to answer that study to

see the light of day. i believe they are obligated to release it, and this is the obligation to deal with the consequences. so they are mandated. >> at the latest, they have to release it by october 2020. one was a study completed? >> it has probably been almost a year now until it was completed, i would imagine. >> that is something that we can ask our congressional leadership to get them to expedite. do you hear that commissioner guggenheim? we want the congressional leadership to put pressure on the f.a.a. to release the new a study that they have and that they are not giving up. >> commissioner guggenheim? >> will do the best we can. can i make one comment about the hearing today? i was born and raised in the city. i've lived here for a couple of years, 78 years. i want to thank the chair of

this committee for seeing the quality of leadership that you have been exhibiting. we will miss you. the city will miss you. you've been terrific. and supervisors, you have done a great job on this. obviously, i live in nob hill and if i don't hear the garbage shoots at various hotels, i hear the airplanes. i can't hear very well anymore either. i do hear that. i think i know the director and the staff are doing everything they can along with the commission to find a way to alleviate this. speaker pelosi, -- hopefully, she has been a lifelong friend of mine capture has been particularly. i will talk to her when i see her and i think with jim lazarus joining dianne feinstein and diane's longtime chair in the

mirror's his office that the pressure will be put on. i can't remember what the power has over the f.a.a. i would hope the f.a.a. director would come out here and spend a day or two in more or -- or more walking around the city so we can understand the personal anguish and it is just not right >> thank you for those comments. i appreciate that. we appreciate your commission engaging on this as well and the leadership director. in no way do i want to diminish the work that you are director has done on this. we really appreciate it. i think at some point -- let's boil it down to the simplicity and you get it on the head. when people can't sleep or people feel peace in their own home, when they did, and they always have, that is probably one of the most disruptive

things that can happen in anyone 's life. so sometimes you think about that. my house in particular, because it is near construction, it has more insulation and it has newer windows. but all of the surrounding in my district don't. most of them are built in the thirties. they didn't think about this. as a gentleman said back there was nothing. they do not build it to those standards. when you do now, on really foggy days, in particular, when i'm putting my kids down at night, account. it is like when you're teaching your kids not to be scared of lightning and you counter the difference between the thunder and the lightning. you sit there and count. and it is in every minute that the flights are flying over. we have more insulation and newer windows. in newer homes is disruptive to

say the least. thank you all for engaging on this. if there is any frustration, it is just because we feel like now we are at a turning point. we have the ability to do something with the abundance of riches in political leadership and you all are included in that i appreciate you all engaging. did you want to say something? >> you actually would have led into which. i'm curious with everything that has been presented so far about the timing and the noise and the amount, how much does weather play in this? is the noise significant during a sunny day or a foggy day or a rainy day, do we have more impact one way or the other? >> i went defer to the director. and often times when we have really bad weather, they shut one of the runways down. >> and depending upon wind and that sort of thing.

i am just curious, generally speaking, do we have a weather factor here? >> sound travels differently depending on the temperature. so when you talk about whether temperature wise it could have probably not a significant effect -- >> that's not my question. my question was, whether the same flight patterns are the same during foggy or rainy weather or does this new next-generation system change when the weather changes, and i'll be curious to know whether that makes the impact of the sound worse or better. >> we go into what is the southeast plan. about 15% of the time, what i described for most of the impact , the residents of san francisco was at 80 5% of times

in norm or just normal operations. when we get into a southwest plan when we have seven storms that that kind of thing, we go into a different -- a whole different operation that has benefit to some communities that suffer under the 80 5% plan, but then has impacts to other communities that don't have that same impact. there is an effect on whether wind is the primary driver too when we go into a straight 28 operation. when we go into that, these folks in the southern part tension not really benefits because then all of the flights go out of the gap. within the focus of daly city and san bruno and south city bear more of the impact. it does move around depending on weather. >> okay. i was just curious about that

factor. thank you. >> thank you commissioners for your comments. i do not want to lose that point i want to overemphasize its. this noise study has been done by the f.a.a. and sitting there for one year. as part of the reauthorization of the budget, they have to release it by the fall of 2020. and i think asking the congressional leadership to release it well in advance of that would have a significant impact on this conversation. thank you director for overemphasizing that. that will be a big first step in terms of some of the things. in a perfect world, i would like to see the possibility of the cystic door system abolished. and going back and fanning out the procedures. i think i would also be informed by the noise study. >> i don't have any other questions at this time. i do want to say for the record, to overemphasize this point. we try to do this later in the day, as well as to coordinate with our airport commissioner

schedules. i did host a town hall at balboa high school. thank you for attending that. it meant a lot to the residents of our district. we do have a significant number of working families. if we did this on a saturday where we did it later in the evening, this entire chamber would be filled. i just want to say that for the record. based on the amount of e-mails and phone calls and outreach and heard from over the time. the folks that are here, we appreciate you coming out to attend. and/or representative organizations that have a significant number of people whose voices they are channeling here today. we will continue to follow up with ms. miss lewis. we will continue to work with commissioners and we will work with the abundance of riches and leadership that we have emanating from san francisco.

all the other ones that have engaged on this issue and contending actors continue to work with members of the board of supervisors and representatives from the community. we feel like we are taking small steps but making progress. i believe that we will see some results that will be positive to the impact of people his lives. i thank everyone for coming out today. [applause] >> we can make a motion to file the hearing. >> okay. i join you in thinking the commissioners and the directors. there is a motion to file a hearing and we will do that without objection. madam clerk, are there any other items for us today? >> there is no further business. >> all right. this meeting is adjourned.

i'm nicole and lindsey, i like the fresh air. when we sign up, it's always so gratifying. we want to be here. so i'm very excite ied to be here today. >> your volunteerism is appreciated most definitely.

>> last year we were able to do 6,000 hours volunteering. without that we can't survive. volunteering is really important because we can't do this. it's important to understand and a concept of learning how to take care of this park. we have almost a 160 acres in the district 10 area. >> it's fun to come out here. >> we have a park. it's better to take some of the stuff off the fences so people can look at the park.

>> the street, every time, our friends. >> i think everybody should give back. we are very fortunate. we are successful with the company and it's time to give back. it's a great place for us. the weather is nice. no rain. beautiful san francisco. >> it's a great way to be able to have fun and give back and walk away with a great feeling. for more opportunities we have volunteering every single day of the week. get in touch with the parks and recreation center so come .

>> my name is naomi kelly the single-story for the 775 i started with the city and county in 1996 working for the newly elected mayor willie brown, jr. not only the chief of staff a woman but many policy advisors that were advising him everyday their supportive and nourished and sponsored united states and excited about the future. >> my name is is jack listen and the executive director of a phil randolph institution our goal to have two pathways to

sustaining a family here in san francisco and your union jobs are stroen to do that i have this huge way to work with the community members and i think i found my calling i started in 1996 working for willie brown, jr. i worked in he's mayor's office of housing in the western edition and left 3 years went to law school of san francisco state university and mayor brown asked me to be the director of the taxicab commission and through the process i very much card by the contracting process and asked me townhouse the city purchaser and worked with me and i became the deputy administrator and . >> having trouble struggling to make ends meet folks will not

understand what importance of voting is so we decided to develop our workforce development services after a couple of years offering pathways to sustainable jobs. >> (clapping.) >> we've gotten to a place to have the folks come back and have the discussion even if participation and makes sense we do public services but we also really build strong communities when i started this job my sons were 2 and 5 now 9 and 6 i think so the need to be able to take a call from the principal of school i think that brings a whole new appreciation to being understanding of the work life balance. >> (clapping.) >> i have a very good team around me we're leader in the country when it comes to paid and retail and furiously the affordable-care

act passed by 3079 we were did leaders for the healthcare and we're in support of of the women and support. >> in my industry i feel that is male dominated a huge struggle to get my foot in the door and i feel as though that definitely needs to change this year needs to be more opportunities for i don't know women to do what tell me dream i feel that is important for us to create a in fact, network of support to young people young women can further their dreams and most interested in making sure they have the full and whatever they need to make that achieveable. >> education is important i releases it at my time of san mateo high ii come back to the

university of san francisco law school and the fact i passed the bar will open up many more doors because i feel a curve ball or an where you can in the way can't get down why is this in my way we have to figure out a solution how to move forward we can't let adversity throw in the in this san francisco office, there are about 1400 employees. and they're working in roughly 400,000 square feet. we were especially pleased that cleanpowersf offers the super green 100% clean energy, not

only for commercial entities like ours, but also for residents of the city of san francisco. we were pleased with the package of services they offered and we're now encouraging our employees who have residence in san francisco to sign on as well. we didn't have any interruption of service or any problems with the switch over to cleanpowersf. this clean power opportunity reflects that. i would encourage any large business in san francisco to seriously consider converting and upgrading to the cleanpowersf service. it's good for the environment, it's good for business and it's good for the community.

>> good evening. welcome to the commission on the environment. tonight, we have two presentations, followed by the closed session performance evaluation of director debbie rafael. special welcome to our guests from the san francisco planning department, the economic world forum, and the silicon valley blockchain society. i want to thank commissioner stevenson for sponsoring the presentation on blockchain society, and its future environmental programs and policies. one of the commission's mandates in the city charter is for us to hold meeting to help educate the department and the public on new trends that may impact the environment in san francisco. blockchain is a very interesting innovation, and many of us, especially me, are interested about learning about this. so let's get started. is there any public comment on

the president's report? hearing none, next item, anthony. >>clerk: the next item is item three, approval. meeting minutes. this item is for discussion and action. >> great. so this is for the september 25 meeting. do i have a motion? >> i move. >> commissioner wan. >> second. >> commissioner stephenson second. is there any discussion or any changes, commissioners, on the minutes? okay. do we have any public comment on the minutes of the 25th of september, the commission meeting? okay. hearing none, all in favor?

okay. motion carries. and the next item is -- >>clerk: the next item is item four, approval of the october 18, 2018 joint meeting with the commission on the environment status of women. this item is discussion and action. >> and this was a very, i think, historic meeting on the commission on the status of women and the commission on the environment. i think it's the first time that both commissions have met to discuss the environmental impacts and how those environmental impacts impact women and families. it was really very thoughtful. lots of lively conversation, as well. do i have a motion to accept the minutes of october 24 the join meeting on the commission of the environment and the joint meeting on the council on the

status of women. commissioner stevenson has made the motion. commissioner wan has seconded it. is there any comments, commissioners? any public comment? hearing none, all those in favor of approving the minutes of the 24 of october, signify by saying aye. vogue vogue. >> any opposed? thank you. next next item. [agenda item read] >> hi. anastasia gliksten, and i wasted a little bit of my time to come here to say shame on you. why do you continuously allow

pesticides to be used on parks? they're not good for us, and particularly bad for children. agriculture uses more, that we need it for biodiversity, it's ridiculous. how can you follow that when each of them are linked -- maybe not to the satisfaction of chemical company, but sufficiently linked with whole array of diseases -- childhood diseases. and just to tell you that davidson was poisoned on 15 of november . this time, they probably didn't

do glyphosate. i went to the -- i forgot -- i meant to get some amount of poison from monsanto for all of you. before this, the mount davidson that i lived to -- now, it's so persistent and basically doesn't go anywhere. i went to presentation and i heard something very interesting. --

[inaudible] >> -- but once you start, he had road egress, and really long training which probably cost the district tons of money. and before this, he was small businessperson who was doing his without any herbicides and it was just fine. another item, i think i have time to say, what they were going to do when they were removing manually cape ivy. you do have to -- what happens if you do it with herbicides, you have to come back and spray again. this i.p.m. meeting in san francisco. thank you. >> thank you. any other public comment -- public comment? hearing none, next item? >>clerk: the next item is item six, discussion of the american

planning association award for excellence in sustainability for the san francisco better roofs ordinance. this item is for discussion. >> yes, and director rafael will present that. so in lieu of our environmental service award, today, we'll be hearing about the award that the city received for an innovative environmental policy. >> thank you, president bermejo. this award was given to us a while back, but due to scheduling, we're coming tonight, and in lieu of the award given to the provide sector, we're talking about an award that we got ourselves. and what is so exciting and interesting for me on this particular award is that there were past commissioners, ruth gravanis, who was such a passionate champion about biodiversity and about the need for green roofs that every time we talked about a green roof as

being a roof that had solar panels on it, she would say it needs to be considered both. and the planning department was thrilled at that, as well because it had been something near and dear to their heart, as well. so this is something that the commission on the environment, the planning commission, and then, the two departments worked hand-in-hand to form a first in the nation policy that has become a model nationally, and so it's time to celebrate and acknowledge the power of what we can do, all of us together. so with that, why don't you come

up. >> good evening. i'm jeff jazzlene. i'm with the san francisco planning department. i'm here to provide an update on the san francisco better roofs ordinance which requires solar panels or gardens on certain roofs since october 2017. i'm joined by barry hooper, primary orchestraitor of a number of the key ordinances, as well as advancement of the ordinance itself. san francisco as we know as a history of being both remarkably cool and impressively green. under the leadership of director rafael and the commission, the city has been widely emulated and a thought in best practices leader nationally and

internationally. until relatively recently, there was an exception to this environmental leadership legacy. the same could not be said of greener living roofs. while we had outstanding examples about the city and a remarkable one in process and transbay, we had no will policies or programs in place specific to their implementation. to begin to address that deficiency, the planning department conspired with the p.u.c. and s.f.c.-s.f.e. to lure the preeminent international green roofs conference to the city. we hosted the cities alive conference in 2013 which catalyzed our bringing together the trades, agencies and other green experts and fanatics. well, actually, we're all fanatics. in anticipation of the conference, spur conveyed a green roof task force which resulted in a specific long range strategy known as a

greener and better road map for san francisco. the road map was announced at the ensuing conference in october 2013. this brought us closer to catching up with other cities such as washington, portland, philadelphia, and toronto. following the conference, a group consisting of representatives from the department of the environment x the planning department, and p.u.c. began to work in earnest to further assess living roof technical and economical efficacy as well as to map out a specific perspective policy. we coined the nomenclature as we were in a drought at the time, and we were concerned that green might equate to excessive irrigation. a cornerstone of our effort was

the commissioning of a cost-benefit study that tested various generic buildings and scales. for each building type, the results were impressively positive. they demonstrated that living roofs were net positive for all projects with substantial environmental and economic profits for the city as a whole. in the process of transparency we ensured that this could be used by other municipalities in other climates, both economic and climateological. this result was pioneering and largely the result of barry's effort. working large wee with our partners, we crafted an agreement in support of senator wiener, with the green roofs

project. the second phase established that solar living roofs are a combination to be deployed. these requirements which took effect on january 31, 2017 constituted the first such mandate in the country. the time between the previously mentioned 2013 conference and the moment the ordinance took effect in 2017 was used to develop a complete geography set of i ever willmentation tools. when the ordinance took effect we were fully implementation ready. and these are among the accrued benefits anticipated to accrue over 15 years. 15 to $100 million in additional tax revenues, between 60,000 and 385,000 tons of carbon he mission avoided or is he

questered. since that time we recently assisted in developing an economic analysis similar to denver to support a citizen driven ballot initiative to garner votes. san francisco was invoked as denver and portland advanced their policy case and made their requirements. we also provided information recently in support to new york and vancouver, both of which are in the process of advancing similar ordinances. since adoption, in addition to the anticipated beneficial results locally, the better roofs ordinance has become an flunl force in advancing the development of this highly effective means for the city in terms of the project and municipal scale to positively and meaningfully respond to

climate change. took us four years to move from that first conversation to implementation, the result and influence has not gone unnoticed. the ordinance received an award from the california chapter of the american planning association for innovation and green community planning about 1.5 years ago, and more recently, the planning department and the department of the environment were bestowed an award because of fully carbon offset and f.c.c. certified award looks like this. that concludes my presentation. i'd be happy to answer any questions, but first, with your permission, i'd like to present this to director rafael, barry hooper, and the planning department on behalf of the san

francisco sustainability association. [applause] >> any comments or questions? >> in the interest of the commission's time, i did not have prepared remarks, but appreciate the great and thorough presentation, jeff, and appreciate the partnership with the planning department and support we've gotten from the p.u.c., particularly water enterprise and the department of building inspection, as well, so it's been a broad every day, spur. a number of community stakeholders, you know, were great contributors, and contributed the momentum that led to the adoption of the ordinance, so really appreciate the out come and it has been an -- outcome and it has been an inspiration elsewhere. thank you. >> thank you. >> yes, sir? [inaudible] >> -- green roofs initiative.

now that we're requiring green roofs, if someone's got a project and it involves a green roof, i guess especially if it's solar, do neighbors have an ability to complain or object based on aesthetics, like in some cities? >> well, it is san francisco. we haven't had that experience, particularly since these are passive facilities. frankly, there have been lots of discussions about rooftop facilities and their impacts, but those impacts have been social because in this case we're talking about nonsocial spaces, other solar or green roofs which are specifically managed as a landscape, not as a park or other type of space. we haven't had that experience. it doesn't mean we won't, but that's our experience so far. >> right.

thank you. >> any other questions. >> do we still not have a shade ordinance? >> shade for -- >> well, i guess it's an antishade ordinance, really, that people can't shade your -- your green roof for your solar? >> we do not. we have allowable building heights. they're -- they're established by the -- by the zoning code, the planning code. part of the opportunity in the flexibility with both the solar and green components as an and-or would be if shading was a potential issue for a solar component that living roofs would still succeed in that environment and could be used in

that. >> that's good. yeah. thank you. >> thank you. >> any other questions, commissioners? is there any public comment? hearing none, maybe we should have a photo. do we need a photo opportunity? yes. let's do a photo -- a quick photo. anthony, do you have your camera or -- >> up here or down there? >> down there. >> okay. some people are --

>> thank you for indulging us with the photo. next item -- >>clerk: just want to make sure -- >> oh, sure want to make arthur there's no public comment. i asked before, but i didn't see anybody jump up. last chance. okay. moving onto the next item. >> okay. item seven, discussion of blockchain technology and the future of environmental programs and policies. this item is for heather stevenson, commissioners, and there's two presentation. one is the uses and technologies of blockchain technology. the speaker is ashley lindquist,

and the second is the change of the future of blockchain technologies. >> okay. thank you, anthony. and before we get started, we just want to remind to hold our questions until the end of all the presentations out of respect for the time of our visiting presenters. feel free to ask clarifying questions during the presentations, but we'll save the longer ones for after the second presentation. also a note to the public that we will take public comment at the end of this item, after the second presentation. thank you. commissioner stevenson. >> hi, everybody. as many of you know, i work in tech startup, so i'm working in technology, mostly the communication since 1996, so i'm dating myself a little bit there, and i mostly focus on communication and marketing. throughout my workday, i interact with a lot of different

startups, and i am constantly thinking about ways that the environment maybe the climate could intersect with technology. unfortunately, a lot of that focused on zero waste because i work in an office where a lot of people are not sorting their trash correctly. we're constantly focusing on our communications plans, all the ways that we use communication across the city to get our message out. but lately, i've been thinking more broadly about technology innovations and how that could impact climate on a broader scale. i had the great opportunity over the last year to have some meetings with some of the folks from c-40 and with debbie, and their women for climate program has a technology challenge that's going on right now, if you know a great women working in tech, if they have some great ideas, the deadline for that is

november 30. i've been thinking a lot about how we can take technology and the environment and apply it in a broadway. specifically this all coincided with me getting really intrigued in blockchain. i'm just one of those people that likes the new stuff coming down the line, and wanting to stay up on it, so i started attending different meeting and hearing different companies presenting about blockchain. there are implications to this tech that could be applied to climate or civic life that we haven't thought about. i talked to debbie and we thought this was an opportunity for us to kind of look toward the future and see what the future has to bring to us or maybe start some conversations that apply to us as time goes on. because as president bermejo mentioned, we have an obligation

here at the commission to educate ourselves and the city on some of these things. i want to thank debbie and the whole energy team who met with me starting about six months ago to talk about this presentation and we -- to start to kind of frame what the issue could look like and we could have these conversations. we decided to break it into three parts specifically. first we're going to hear a blockchain 101-style presentation. it's hard to think about. we all think it's bitcoin and cryptocurrency, but it's more than that. we thought we'd bring in some people to talk to you about that. secondly, there's going to be a discussion about potential pit falls. you may have read some things in the news about energy usage surrounding blockchains, so we're going to have a conversation around things like that. some of things like privacy also come up during that discussion, and finally there's going to be a discussion on potential

opportunities to use blockchain for developing future environmental programs and policies. we're very excited about that. we're very fortunate to have with us today to very remarkable and distinguished experts, ashley landquist of the world economic forum is going to be giving our first presentation, and aman ban is the president of the world blockchain foundation. thank you. >> hi, everyone.

between multiple parties in a verifiable and permanent way. in the system, generally speaking, the technology offers a distributed and synchronized mechanism which is aimed, or would be comparing against a centralized system. basically centralized data bases. we are talking about decentralized data bases no one has. assets, whatever the transaction

may be. transparency. traceability of the transactions. irreversible records and automatic execution. automated smart contract. so first, the ledgers or distributed ledgers is the term for this. we distributed. there are thousands of computers around the world. second with the network. and they all continuously downloading and
