Climate change is not just an environmental issue

Over recent months the EU, the US and, most importantly, China, have all made substantial commitments to cut the growth of greenhouse gas emissions. They represent important progress but we need to challenge every country to be as ambitious as possible. Because even if agreement can be achieved, it may not be enough to address the scale of the challenge we face. This would make it all the more likely that we will not do what is necessary to meet our obligations to future generations.
