They are known as “the twins”, born in 1992 at the Earth Summit in Rio de Janeiro but diplomatically separated and left to develop at different speeds. One is the UN’s climate change convention, or UNFCCC, now a fully fledged global agreement with huge annual summits attended by heads of state and rock stars pledging to reduce emissions.
The other, the UN convention on biological diversity (CBD), aims to protect the world’s 10 million species of animals and plants, but it meets less often, is modest by comparison, and has yet to make its mark with the public in the same way as climate.
