Carbon Budget

Back to Overview

The carbon budget indicates the amount of greenhouse gases that humanity “is allowed” to emit into the atmosphere in order to reach the 1.5°C target of the Paris Climate Convention. According to the Mercator Research Institute on Global Commons and Climate Change, with current emissions, this budget will be exhausted by early 2028, whereas for the 2°C target we still have until the end of 2045. The basis for this calculation is an annual global emission of 42 Gt per year and a carbon budget of 420 Gt or 1160 Gt according to the scenarios.
