Delivering the greenest government ever will require strong and decisive leadership. The benefits to countries who lead the way in low carbon technologies and approaches are great, from energy security to more resilient communities. This government has recognised the need to move from warm words to real action, to secure these benefits and to avoid irreversible climate change. This debate will focus on the new political landscape in relation to climate change and identify priorities for early action. What are the smart options for political leaders and policy makers to drive the transition to a low carbon economy at the same time as building far greater public support? How can politicians best demonstrate the practical and economic benefits of cutting carbon? What should civil society expect to see from ministers and MPs over the next 12 months?

Climate change is an international challenge that needs an international solution. This debate will look at the big picture of the global politics of climate change since Copenhagen, and how we can expect this to play out alongside other, ‘more established' foreign policy issues such as nuclear proliferation, energy security or trade. Is climate change treated in the same way as more traditional foreign policy issues, and how does it differ? How has the relationship between the old powers of the USA and EU and the new rising powers of China and India changed, and where does this leave the poorest and most vulnerable countries? What are the prospects for achieving a lasting international solution to this most urgent global threat? And can Cameron steer a course to success where others have failed?
