The Climate Action Tracker
L o a d i n g
The Climate Action Tracker is an independent scientific project that tracks government climate action and measures it against the globally agreed Paris Agreement aim of "holding warming well below 2°C and pursuing efforts to limit warming to 1.5°C." A collaboration of two organisations, Climate Analytics, and NewClimate Institute, the CAT has been providing this independent analysis to policymakers since 2009.

- At their best, well-designed and ambitious net zero targets are key for reducing global carbon dioxide and other greenhouse gas emissions to net zero around 2050 and 2070, respectively. This is necessary to keep to the Paris Agreement’s 1.5°C temperature limit. Ambitious net zero targets can also guide the implementation of Paris-aligned actions in the short and medium term, in particular 2030 emission reduction goals.1Licence not specifiedabout 2 years ago
- As of November 2022, a substantial gap remains between the levels of emissions in 2030 projected in the NDCs submitted to the UNFCCC and between current levels of government action, and the lower levels that would be consistent with the temperature limit of the Paris Agreement. The benchmark emissions from a 1.5°C compatible pathway are at 27 GtCO2e in 2030. The emissions gap between this level and 2030 NDCs (excluding hot air)[1] is 19–22 GtCO2e in 2030 (the 'targets gap'), and 23-27 GtCO2e in 2030 for current policies and action (the 'implementation gap').1Licence not specifiedabout 2 years ago
- The Climate Action Tracker decarbonisation data portal provides a dashboard to track decarbonisation per country in various sectors. The portal aims to facilitate understanding of what factors drive the overall emissions trend in different countries (‘Where are we?’) and, for selected indicators, what the best-in-class/2°C/1.5°C compatible benchmark level would be (‘Where do we want to go?’).1Licence not specifiedabout 2 years ago
- The temperatures on the CAT thermometer are ‘median’ warming estimates in 2100. This means there is a 50% chance that the calculated temperature will be exceeded if the given emissions pathway is followed. The ‘median’ is based on the probability distribution generated by the climate model (MAGICC7) when it takes into account uncertainties in our knowledge of climate sensitivity, the carbon cycle, and the effect of greenhouse gases, aerosols, and other factors that are used to calculate the temperatures1Licence not specifiedabout 2 years ago
- Limiting warming to 1.5°C above pre-industrial levels means that the greenhouse gas emissions need to be reduced rapidly in the coming years, about halved by 2030, and brought to zero soon after around mid-century. The CAT evaluates progress towards this global goal by quantifying the aggregate effects of current policies and the pledges and targets put forward by countries and compares these with the emissions levels consistent over time with the 1.5°C limit using the MAGICC climate model.1Licence not specifiedabout 2 years ago
