now the united nations intergovernmental panel on climate change says more people could be fed usinga switch to plant—based diets. our environment analyst, roger harrabin, reports. this alpine landscape was once covered by forest, the trees sucked carbon dioxide from the atmosphere and regulated the climate. then humans cleared some of the land forfood but cattle burp methane and that strongly heats the atmosphere. this sort of low intensity grazing may produce protein from poor soil and it does have some environmental benefits but it create more greenhouse gases than growing plant protein. scientists meeting here in the alps are not saying we have all got to go vegan to protect the climate, they are saying that we do need to cut down on red meat and dairy produce and shift on towards eating more vegetables. and that message may not go down very well here in a region that is so heavily dependent on cheese and meat. we need to do what we can on the land but actually it's important to maintain food production and so there will always be some emissions on land. so in fact we have to do

there are some interesting remarks from zhou dadi, a member of china's national expert panel on climate changer one emitter of greenhouse gases. we hold our hands up, so china will take more action internationally to combat climate change. he then said china had already reduced emissions intensity relative to gdp by 44%, which is quite handy because he promised to get it down by 45% by next year. so he said a study suggests it is very likely we can achieve this target before 2025. in other words, peak absolute greenhouse gas emissions by 2030, we can do it five years earlier. these are political statements. do you believe them? look, from china, i am encouraged by them. the big issue for china as i understand at the moment is the growth in the vehicle sector, you know, because the number of new cars coming online is huge. so they seem to be making very good progress with their electric vehicle manufacturing, and i am hopeful that they can do that by 2025. i mean, that will be the single biggest contribution towards actually achieving what we need to do — stay below two degrees. there are a lot
