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 The Climate Scoreboard analysis below is no longer being updated and does not reflect the latest pledges countries have put forward.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.
The Climate Scoreboard shows the progress that the national plans submitted to the UN climate negotiations will make in mitigating climate change. Our analysis shows that the national contributions to date, with no further progress post-pledge period, result in expected warming in 2100 of 3.2°C (with a range of uncertainty of 1.9 – 4.4°C). This analysis includes the Intended Nationally Determined Contributions (INDCs), Nationally Determined Contributions (NDCs), and long-term strategies.
The analysis was conducted using the C-ROADS climate policy simulator. The Climate Scoreboard shows the expected impact of the plans nations have submitted to the UN Framework Convention on Climate Change (UNFCCC) and assumes (1) the pledges are fully implemented, and (2) that no further reductions occur beyond those that have been formally pledged, specifically, actions after the end of the country’s pledge period. The plans include:
Nationally Determined Contributions – Plans submitted to the UNFCCC once the country or member state has ratified the Paris Agreement. In most cases when members ratified the Paris Agreement their INDCs became NDCs. Currently NDCs typically end in 2025 or 2030, however countries will be asked for additional NDCs in the coming years.
Long-term Strategies (also called Mid-Century Strategies) – Proposals that communicate the decarbonization pathway a country aspires to follow out to 2050.
Any analysis, including ours, that offers an expected temperature change in 2100 includes assumptions about what will happen after these contributions end. Thus, we also analyze scenarios in which nations are assumed to pledge and implement additional action. Greater ambition leads to further reductions in expected warning. For example:
National Plans – 3.2°C (5.8°F) – No change after national contribution pledge period.
<2.0°C Path – 1.8°C (3.3°F) – All countries peak by 2030 and then reduce steadily, with rates in the post-2030 period faster in the developed countries (5%/yr) than in the developing countries (3.5%/yr).
1.5°C Path – 1.5°C (2.8°F) – All developed countries peak by 2025 and then reduce steadily at 10%/yr; all developing countries peak no later than 2030 and then reduce steadily at 8%/yr.
With action to reduce fossil fuel emissions and greenhouse gas emissions from other sources, the world can still realize the pathway that keeps warming well below 2.0°C this century.

How You Can Help
Share the Scoreboard. You can follow, talk about, and publicize the progress of the global negotiations.
Engage others in a powerful simulation game. Join others who are bringing the international climate negotiations to schools, organizations, or groups in their communities by running our World Climate simulation game.
Exercise your power as a citizen. Based on what the Climate Scoreboard is reporting, you can thank those governments that have made responsible pledges, and you can demand more from those governments who need to do more.
