In the INDCs each country specifies what action it intends to do in terms of both climate adaptation and mitigation, and how these efforts are to be measured and reported. The INDCs have a central role in the Paris Agreement as they will constitute the basis of the new agreement.

Each party at the convention is encouraged (but not forced) to submit their INDC to the UNFCCC before the meeting begins. By now, most countries have submitted their contribution and all submissions are available on the UNFCCC website. While there are guidelines for what kind of information they should contain, each country decides to decide what their contribution looks like.

As a result, the submissions can look very different. For one, countries have chosen different years for when their emissions will peak and different base years for comparisons. Such differences complicates any cross-submission comparisons. Many countries have also been accused of lacking ambition.

We do, however, think it is important to emphasize that these contributions should be seen as the floor, or the minimum ambition, of what countries intend to do - not the ceiling. This explains why many countries are set to outperform the goals specified in their INDCs.

The correct answer to yesterday's question is: 40-70%. Did you get it right?
