A CO2 budget for everyone on earth

German Minister for the Environment, Norbert Röttgen, is pleading for a CO2 emission limit for everyone on earth. It’s going to be difficult climate talks in Durban at the COP17 these upcoming weeks. (At least everyone agrees on that.) But to come to terms on climate protection goals, he says in an interview with Der Spiegel, a German weekly newsmagazine, inevitably there has to be a CO2-budget for the emission of greenhouse gases per capita in the future.
