Climate change campaigners should be cautiously optimistic after the latest UN Climate Summit

World leaders met in New York on 23 September for a ‘Climate Summit’ with the aim of discussing some of the measures that will be contained within a new climate change agreement in 2015. Federica Genovese writes that while the summit provided little in the way of new commitments, it nevertheless demonstrated that the international community of climate policy supporters is growing ahead of the United Nations Framework Convention on Climate Change in December.
