A quick note: Climate Interactive was one of the first teams to add up all the pledges countries were putting forward for the UN climate change negotiations initially around the Copenhagen climate talks in 2009 and the analysis played a historic role in the ensuing ten years of negotiations. During that time the addition of assessments like the UNEP Emissions Gap report, expanded efforts like the Climate Action Tracker, and many others, the need to offer another analysis of the gap between where policies are headed and what is needed has felt well covered. As a result, Climate Interactive has decided to invest our time in other endeavors. The Climate Scoreboard analysis below is no longer being updated and does not reflect the latest pledges countries have put forward. The C-ROADS simulation model that we used to create this analysis is still updated and available for your use. We encourage you to continue using C-ROADS with groups to interactively create your own scenarios for what is needed to address climate change.
Climate Interactive and MIT Sloan used the C-ROADS climate policy model to simulate hundreds of scenarios with combinations of mid-century strategies for different nations. We identified more than 600 that succeed in limiting expected warming to no more than 2°C by 2100.
This analysis provides pathways that countries could follow to ensure their long-term emissions trajectory is consistent with the Paris Agreement goal to limit warming to well below 2°C and aim for 1.5°C.
