Today I officially walked out of the climate negotiations. I handed in my badge with 8 hundred others in an act of solidarity. We are in disbelief at the lack of ambition that has been bought to these negotiations.

I have walked out to send a message to Governments - we cannot afford to delay these talks anymore! We came to COP19 to see ambitious pledges and a clear path forged for the agreement to be made in 2015. Instead we have seen backwards steps taken by some countries namely Japan, Canada and Australia. We have seen other countries delay progress. We have seen no significant financial pledges made to scale up long term finance. Our scientists tell us we need to peak emissions by 2017 – we are not even close to that with the current ambition.

I have walked out because this is the most powerful message I can send to countries to get serious. Go back home and consult your people, tell them how significant the challenge we face is. Go to Lima (COP20) with ambitious targets and a willingness to create an agreement that reflects what is needed. I have walked out because I can no longer add anything to these negotiations. All I can do now is go home and teach people what I have learnt and encourage my country to stand up for what is right.
