The Paris Agreement aims to limit global warming to well below 2°C above pre-industrial levels and pursue efforts to limit it to 1.5°C. To achieve this, countries have submitted Intended Nationally Determined Contributions (INDCs) outlining their post-2020 climate actions. The current INDCs collectively reduce greenhouse gas (GHG) emissions compared to current policies, but still imply a median warming of 2.6–3.1°C by 2100. More can be achieved, as the agreement calls for strengthening targets over time. Substantial enhancement or over-delivery on current INDCs is required to maintain a reasonable chance of meeting the temperature target. The analysis assesses the implications of current INDCs for GHG emissions, the factors influencing these emissions, and the consistency with the Paris Agreement's temperature objective. It also explores the potential for accelerated action after 2030 to limit warming to well below 2°C. The findings highlight the need for additional national, sub-national, and non-state actions to reduce emissions and achieve the Paris Agreement's goals.The Paris Agreement aims to limit global warming to well below 2°C above pre-industrial levels and pursue efforts to limit it to 1.5°C.
