There’s been limited progress … I sense frustration, especially among the developing country groups here at Cop. This is my 18th Cop – my first was Cop10 in Buenos Aires in 2004, in the distant days when Argentina was a developing world climate champion. When the totemic target of ensuring $100bn would flow to developing countries each year by 2020 was put on the table, in the last days of Copenhagen, it was done with only brief prior discussion. Lammy wanted to announce the UK’s return to climate leadership on the global stage, in contrast to his Conservative predecessors. Finding the money to put developing countries on to a green path makes sense for rich countries, and for rapidly developing economies such as China, as much as it does the poor.
