To keep global warming below 2°C, the international community needs to maintain the total cumulative emissions below 1,000 billion tonnes of carbon dioxide. This is our ‘carbon budget’. So far we used 595 billion tonnes or nearly 60% percent of our carbon budget. 

Trillionthtonne expects that the 1,000 billion tonnes will be emitted by 31 October 2038. The international community is called to agree upon a sound post-2020 climate governance in order to attempt at reverting current trends and stay within our carbon budget.
