This article discusses how will the world know how much carbon is being emitted? As climate negotiators consider rules for verifying commitments under the Paris Agreement, they will have to confront a difficult truth: There currently is no reliably accurate way to measure total global emissions or how much CO2 is coming from individual nations.
Will we be able to verify the Paris climate accord? Right now science is not up to the task, say the people in charge of assessing our annual emissions of CO2. There is, they say, no sure way of independently verifying whether national governments are telling the truth about their own emissions or of knowing by how much global anthropogenic emissions are actually increasing.
