an ambitious new target for the uk to cut carbon emissions to almost zero in the next 30 years. the government's climate change advisers say there's no time to lose — they're calling on us to switch to electric vehicles, eat less meat and plant more trees. we meet one family who've taken up the challenge of leading greener lives. when we moved here we were in no hurry to get a car, and wejust kind of decided that we'd see how we got on without one. and we've managed quite well with that, as a family, so we've just decided no, — no, no regrets. and we'll be live in china to see what the rest of the world is doing to combat climate change. also this lunchtime: sacked defence secretary gavin

williamson says he's the victim of a kangaroo court — the government won't call in the police. the prime minister has said that she now considers that this matter has been closed, and the cabinet secretary does not consider it necessary to refer it to the police. a new inquest into the death of ella kissi—debrah, amid claims that illegal levels of air pollution caused the asthma attack that killed her. and victims of uk terrorism talk about the trauma of coming close to death. the fear was incredible. i was convinced that i was going to die on that evening. and i didn't know how it would happen, i didn't know when it would happen, but it's the only time in my life that i've felt that i was going to die. and coming up on bbc news... seven minutes of magic from lionel messi inspires barcelona to a 3—0 win over liverpool

in the first leg of their champions league semifinal. hello, good afternoon and welcome to the bbc news at one. britain should lead the global fight against climate change, according to a new report today. the government's independent advisers on climate change say the uk should cut greenhouse emissions to virtually zero by 2050, and say "there's no time to lose". the committee on climate change says it could mean us switching from diesel and petrol vehicles to electric ones, eating less meat and planting more trees. here's our environment analyst roger harrabin.

when britain sparked the industrial revolution we didn't know burning coal, oil and gas would produce emissions that would overheat the climate. now a green industrial revolution is under way, and advisers say that by 2050 the uk should add no more heat and gases to the atmosphere. this target with cheap renewable energy is called net zero, which means industries will have to carbon emissions much more quickly and power plants like this in yorkshire will lead the way. industry says it will need help. in yorkshire will lead the way. industry says it will need helpm the government accepts this target and clearly commits to a net zero target by 2050 then we put the policies in place behind that, businesses will absolutely rise to the challenge. farming must play a part. burping cows are heating the climate and the committee expects people to be eating around 20% less

meat. trees planted on farmland can help absorb some of our carbon emissions. housing must be net zero emissions. housing must be net zero emissions as well. look at the insulation on this modular home in northamptonshire. it is called e—topia, the house kept warm thanks to solar panels on the river, which will heat hot water in the summer down through a grid of pipes under the home. that leaves the soil under the home. that leaves the soil under the house and creates a bowl of warmth which can be drawn on to heat the home in the winter —— heats the soil under the house. existing homes will also need to be better insulated. even then, the report says theres should be set at 19 celsius to save energy. that may prove unpopular. electric cars will do their bit. the report says ideally after 2030 no new conventional cars will be sold in the uk. people will continue to fly,

but on aircraft powered by fuel from waste, but the growth in flying must be constrained. the extinction rebellion group have been piling on the pressure over the climate and they say today's recommendations are too weak. we are still with this thing that if ijust turn the thermostat down, take one less flight, it thermostat down, take one less flight, it will all be ok, and i think the truth extinction rebellion are telling everyone is it is not going to be ok, stop kidding yourself. today's report does not guarantee a stable climate but it is the most ambitious attempt yet from any nation to stop adding to climate change. roger harrabin, bbc news. the committee's report sets different targets for different parts of the uk, with a slightly less stringent one for wales because of its reliance on agriculture, and a slightly tougher target for scotland because of its potential for planting trees. 0ur environment correspondent

kevin keane has spent the day with one family in aberdeenshire who are doing their bit to fight climate change. meet the martins, living a low—carbon lifestyle in aberdeen. mum, rachel, and dad, ben, had the family. —— head the family. then there's their two children, elizabeth and daniel. they live on a plant—based diet, meaning they don't contribute to animal emissions. i am cooking tonight yellow split peas... the kids still eat meat occasionally if they're out, but not at home. i'm assuming mum makes the best food in the world, but... most of the time, quite a lot of the food she cooks is delicious, so... what's your favourite? well, i don't know, but i quite like the daal she's cooking right now. the martins are a car—free family. they're members of a car—sharing club for longer distances, but most of theirjourneys are on foot or by bike. for ben that even means a shorter

commute to and from his work at the university. when we move here, we were in no hurry to get a car. and we just kind of decided that we'd see how we got on without one. and we've managed quite well, as a family, so we just decided no — no, no regrets. no holidays abroad, especially if that'd involve travelling by air. that's dad with his eyes closed. so this easter‘s adventure was to glencoe. the last time he used a plane was probably pretty long ago now. do you mind that? well... i don't know. i don't necessarily mind it. rachel shuns fast fashion, and buys most of her clothes from charity shops. she's alone in this, but thinks it's worthwhile. it's made in london and quite old, but i don't think it was ever worn until i got it, and that is just to me a real find,

a lovely wool tartan skirt. they are not living a zero—carbon lifestyle, but doing the best they can in a world that's not designed for this style of living. perhaps today's report will be the catalyst that brings about that change. kevin keane, bbc news, aberdeen. so what's the rest of the world doing to cut emissions? well, china emits over a quarter of the world's greenhouse gases, and our correspondent robin brant is in china's biggest city, shangai. robin, how hard are the chinese trying to combate climate change? —— shanghai. they are trying very hard, china signed up to the paris card, and lots of reasons for the government to try to deal with emissions here —— the paris accord. this night—time rainbow down in the city of shanghai, common in hundreds of cities across china. cities like this have expanded hugely over the

last 20 years and much of this power comes from coal, the big problem. 59% of china's power is generated by coal, 70% of its carbon dioxide emissions at the moment caused by coal. we have seen those emissions increase as well, and that is the big problem. ithink increase as well, and that is the big problem. i think one of the biggest challenges for this country's government, led by xi jinping, it hasi.4 country's government, led by xi jinping, it has 1.4 billion people it needs to cater for, an economy thatis it needs to cater for, an economy that is still growing at a very healthy rate of 6.5% compared with, say, the uk, and it wants to maintain that kind of stability, but air quality is a big problem here. much of that caused by coal powered stations, and i explained that for six months of the year in china that is really pushing the government to deal with climate change domestically. 0n the one hand, it is pioneering new energy vehicles, electric vehicles. it wants a fifth of all vehicles on the road here in

six years' time to be electric vehicles, but remember growth is slowing down and in the last couple of years we have seen stimulus efforts. they want people to buy more cars, to consume more, and all of that means more power, more electricity, inevitably. robin brant in shanghai, many thanks. the government is not planning to call in the police over the leak of classified information from the national security council, which led to the defence secretary gavin williamson being sacked last night. labour want a criminal investigation into whether the leak was a breach of the official secrets act. mr williamson has strongly denied being the source of newspaper reports about the potential involvement of the chinese firm huawei in britain's 5g network and says he's been the victim of a "kangaroo court". here's our political correspondent ben wright. welcoming the leader of iceland to number ten this morning, day after

dispatching her defence secretary in one of the most extraordinary ministerial sackings of recent yea rs. ministerial sackings of recent years. prime minister, did you get the wrong man? she told gavin williamson there was compelling evidence he was behind an unprecedented leak of secret information from the national security council last week about the chinese firm huawei's potential involvement in the uk's 5g network, but before his sacking mr williamson denied any involvement in leak. are you or any of your officials behind the huawei... you or any of your officials behind the huawei. .. absolutely not. you or any of your officials behind the huawei... absolutely not. he has continued to protest his innocence since saying a thorough inquiry would have cleared him. in the common the prime minister's deputy said the matter was closed. the unauthorised disclosure of any information from government is serious, and especially so from the national security council. the prime minister has said that she now considers that this matter has been closed, and the cabinet secretary

does not consider it necessary to refer it to the police. but labour said the matter needs further investigation and has called for a criminal inquiry. the prime minister believes her former defence secretary leaked information from the national security council. he vehemently denies it. only one of these accounts is accurate. i don't think we have ever seen a leak from the national security council and that's why this is so serious. one tory mp said further proof of gavin williamson's actions was needed. naturaljustice williamson's actions was needed. natural justice demands that williamson's actions was needed. naturaljustice demands that the evidence be produced so his reputation can be salvaged or utterly destroyed. doesn't it? the police won't get involved unless the head of the civil service thinks the 0fficial secrets act has been breached, and as it stands that is not happening. number ten's view is this was a political misjudgment of gavin williamson of the most serious

kind. leaking information from the national security council, where secrets are shared between senior ministers, intelligence and defence chiefs. mr williamson is kept out of sight today, but is adamant he has been wrongly blamed for a leak that has sunk his career, and launched a bitter argument between theresa may and the man who used to be one of her closest allies in government. ben wright, bbc news, westminster. 0ur chief political correspondent vicki young is in westminster. the government is saying this affair is closed. is it? yeah. they are saying this is not about what was leaked, but is about where it was lea ked leaked, but is about where it was leaked from, and they say ministers and members of that national security council have to be confident that the conversation, the discussions they have, will remain confidential. there was a rebuke from david lidington today in the commons towards ministers, saying they should speak with candour in they should speak with candour in the room but shut up when they leave it. as we are hearing, the

opposition are pushing for a police investigation to see if the official secrets act has been broken in any way, but there is a formal process. the net police say they would need a referral from the cabinet office and it is pretty clear today that is not going to happen —— the metropolitan police say. meanwhile gavin williamson denying he passed on any information in that 11 minute phone call with a journalist involved and he feels he has been stitched up, but not a lot of sympathy from his colleagues. 0ne but not a lot of sympathy from his colleagues. one said he was over promoted and self—serving, and a cabinet minister is booked earlier simply doesn't believe the denial, saying he spoke to the journalist and, let's face it, they were not speaking about the weather. vicki, thank you very much indeed. vicki young, at westminster. the canadian aerospace firm bombardier is putting its belfast operation up for sale as part of a reorganisation of the business. the company, which also has factories in morocco, is selling

its entire aerostructures operation. bombardier employs around 3,600 people across several locations in northern ireland. the company said it is committed to finding the right buyer. the wikilea ks founder julian assange has begun his fight against extradition to the us over allegations he conspired to break into a classified pentagon computer. as protestors gathered outside the court, he appeared via video link from belmarsh prison for his first extradition hearing since being removed from the ecuadorian embassy in london where he had been in hiding for nearly seven years. mr assange said he would not surrender to the extradition and he had produced journalism that was "award winning" and "saved lives". the infected blood inquiry has heard evidence from a woman who was infected with hiv through her haemophiliac husband after doctors persuaded him to take contaminated medicines. the inquiry has already heard

heart—rending testimony from several victims of the scandal — and today clair walton told her story. sophie hutchinson is at the inquiry in central london. clair walton was the first of the family members to give their testimony is here at this public inquiry, and she described how she was infected through her husband. he was infected through her husband. he was given contaminated blood products for treatment for his severe haemophilia. he was infected with hepatitis c and hiv and as a result of that infection clair walton became infected with hiv. she told the inquiry he was never properly warned of the risk of these blood products, and in fact doctors had almost sort of praised him for having so many antibodies in his system against hepatitis c, to protect him from it, because he had been exposed to the virus so many times. she said medical staff knew

about the dangers, and she described about the dangers, and she described a time when her husband was pressured to keep taking the contaminated medicines. he was told that there was a shortage of the factor eight, of the old stock, and that they were keeping the good stuff for the little boys — the boys that hadn't been given, hadn't received hiv — and bryan accepted that. he accepted it and i think that's a mark of the man he was, that he was put under that emotional blackmail, you know, and to continue to take what potentially was old stock, infected blood products. claire wilton also heavily criticised the now—defunct macfarlane trust, which provided financial support for some of the

victims. she said in a quote that they had been benefiting from people dying. she said they had also held her and her husband in contempt when they were given a loan, the macfarlane trust bot part of the house. the enquiry heard that loan had now been written off and there was a round of applause here. sophie hutchinson reporting. our top story this lunchtime. an ambitious new targets for the uk to cut carbon emissions to almost zero in the next 30 years. and still to come... we'll be live at the start of the tour de yorkshire, where anti—fracking protesters have gathered to protest against team sky's new sponsors — the energy firm ineos. coming up on bbc news... shaun edwards is going to leave the wales rugby union set—up after this year's world cup. he's been defence coach since 2008, winning four six nations titles and three grand slams.

a fresh inquest is to be held into the death of nine—year—old ella kissi—debrah — who died after suffering an asthma attack in 2013. the original inquest concluded her death was caused by acute respiratory failure and severe asthma, but her family says new evidence proves her death was directly linked to illegal levels of air pollution near her home in south london. jon donnison reports. up up until 2010, ellie kissi—debrah had been a healthy young girl. after a chest infection she developed severe asthma. she was hospitalised 27 times over three years and died in 2013, just nine years old. the following year an inquest concluded she died of acute respiratory failure and severe asthma. but ella

lived just yards from the busy south circular road in south london and herfamily have circular road in south london and her family have always believed air pollution directly contributed to her death. after a six—year legal battle, her mum walked out of the high court today with a victory. the original inquest verdict quashed, and a fresh inquest ordered, which will hear new scientific evidence backing the family's claims. ella's mother also wants poor air quality to be included on her daughter's death certificate, some of the —— something the family believes would bea something the family believes would be a first. it's important, for her siblings who are quite young, to understand why she died and at the moment it's not there. for all she suffered, three comas, she deserves that and this is her moment, although she's not here, it really is her moment. the court heard that the family believe that government should be held responsible for

illegal levels of air pollution in their area. they also think this case could set a precedent and doctors say that each year in the uk air pollution is a factor in the deaths of some 40,000 people each year, much of it from traffic. a fresh inquest into the death of ella kissi—debrah is expected to start later this year. jon donnison, bbc news, at the high court in central london. india is evacuating 800,000 residents and tourists from low—lying parts of the south—eastern coast, in the face of a giant storm. tropical cyclone fani is sweeping in from the bay of bengal with wind speeds up to 127 miles per hour. it's already passed over sri lanka and is expected to make landfall tomorrow morning, before moving towards bangladesh. olympic champion caster semenya has hinted that she might walk away from athletics. yesterday she lost her appeal against new rules on testosterone

being able to is courage. walking away with your head held high is dignity. a further message read, that's me and always will be, i'm finished. if she does walk away from the sport, then scrutiny of the athletics world governing body and its new regulations will increase. its president continues to back its stance. athletics has two classifications. it has age, it has gender. we are fiercely protective about both, and i'm really grateful that the court of arbitration has upheld that principle. the complex issue has split opinion amongst fans of the sport, but there was support today from some of the south african‘s fellow athletes, including team gb sprinter dina asher—smith. caster is my friend, so i hope she'll be ok. caster semenya wants to compete freely. however, there are increasing signs that reigning world and olympic champion‘s career could yet be brought to a halt. richard conway, bbc news.

various issues, such as suggestions that they'd crossed ethical lines, such as the huge spending and there unspectacular style of riding, but they've come together and they were they've come together and they were the focus of attention here this morning with chris froome setting off from here and leading the new tea m off from here and leading the new team out. now, you mentioned the protesters. they were relatively small in number, good—natured, nothing too divisive, but they were vocal and we'll be waiting to see what happens on the rest of the four day race, which culminates today in selby and finally on sunday. david 0rnstein reporting from doncaster, many thanks. voting is taking place today in local elections across england and northern ireland, to decide who'll run services such as housing, school admissions and rubbish collections. there will also be elections for six directly—elected mayors. there are no local elections this year in wales or scotland. the first results are expected

inquests begin next week into the 2017 london bridge terror attack, which left eight people dead. for those who were there, it will mean re—living the trauma of that day. now, for the first time, two women caught up in separate terror attacks in london have spoken about the impact on their lives. here's our home affairs correspondent, danny shaw. we walked away from situations that could have killed us, hugely affected us much more, but i think the psychological effects are definitely something we share. they've become friends through adversity. two women who survived separate terror attacks in london reliving their experiences on camera for the first time. sirens. injune 2017, eight people died in van and knife attacks near london bridge. natalie tait was eating

out with a friend. the whole market just went into chaos. screaming. we heard gunshots, very quick, um, very, very loud gunshots and with that the chap from the restaurant said, "come in, come in," and we basically locked down in the restaurant. the fear was incredible. i was convinced that i was going to die on that evening and i didn't know how it would happen, i didn't know when it would happen, but i...it‘s the only time in my life that i felt that i was going to die and that fear takes over your whole body. the explosion, the noise, i knew instinctively that it was some sort of a bomb that went off. joanette fourie was on a train at parsons green station when a device packed with nails and knives partially exploded.

knowing what to do. so i knew i had to get off, had to call 999, i had to make my way out. voice over: a terrorist's method of operation is... joanette knew what to do because she'd had training. police are encouraging others to do the same, to help them cope if there's an attack. some of the victims and survivors of terrorist attacks that i've worked with and spoken to over the last year or so, they've told me, where they have had a bit of training, and they have been able to give a bit of thought to the situation they've been caught up in, they've been able to respond differently. either protect themselves better, or, as importantly, protect others. the bombings in sri lanka brought back painful memories for joanette and natalie, but their experiences have made them stronger. it is a reminder that things can happen and you're not always 100% safe, even when you might assume that you are. but equally, i won't continue to be troubled, because they're not having that.

they will not win by affecting the rest of my life. danny shaw, bbc news. one of horse racing's most successful jockeys, ruby walsh, has announced he's retiring from the sport. the 39—year—old has ridden over 2,500 winners in a career spanning a quarter of a century. he's gone out in style, riding kemboy to victory in the punchestown gold cup. racing legend ap mccoy has described ruby walsh as the greatest jump jockey of all time, and compared him to lionel messi on a horse, saying what he had was uncoachable and unteachable. princess charlotte's fourth birthday has been marked with the release of three photographs taken by her mother. charlotte, who is fourth in line to the throne, was captured by the duchess of cambridge at kensington
