What needs to come next after the first Kyoto Protocol period expires in 2012? If we agree that 2 degrees centigrade is the maximum limit beyond which dangerous climate change takes hold – and that to avoid this we need to stabilise emissions of all greenhouse gases at around 400ppmv (CO2 equivalent) – then it is clear that we urgently need a much stronger agreement if we are to reverse the current global trend of rising emissions.
How do we avoid the arguments about the amounts of greenhouse gases that individual nations are able to emit and make sure that we do not end up with another inadequate agreement?
Under the Contraction & Convergence solution, a scientifically-informed emissions reduction curve is drawn up which results in every person on the planet ending up with an equal right to emit. We speak to the architect of the scheme, Aubrey Meyer of the Global Commons Institute.
