Remaining carbon budget – that’s how fast the carbon clock is ticking

The clock is ticking. The carbon clock of the Mercator Research Institute on Global Commons and Climate Change (MCC) shows just how little time is left for political decision-makers. Visitors to the MCC website can find out how much time is left to implement effective action based on various policy objectives and scientific assumptions.

The MCC carbon clock demonstrates just how much carbon can be released into the atmosphere if global warming is to be limited to 1.5°C, or 2°C with high probability. By selecting a choice of temperature targets and estimates, you can see how much time remains in each scenario.

Disclaimer: The numbers are based on the latest Assessment Report (AR5) of the IPCC. It is very likely that these numbers will be updated after the release of the IPCC’s Special Report on 1.5 Degrees. This will then be considered here accordingly.

The calculation is based on the assumption that annual emissions remain at the level of 2014; while between 2000 and 2010, an annual growth of greenhouse gas emissions of 2.2% has been observed.
