Climate change is one of the biggest threats and injustices of our time. Nationally Determined Contributions (NDCs) are national climate action plans that embody efforts by each country to reduce national emissions and adapt to the impacts of climate change. They are the single most important instrument for the implementation of the Paris Agreement and achieving its long term goals for climate adaptation and mitigation. The Paris Agreement on Climate Change requires Parties to submit new or updated Nationally Determined Contributions (NDCs) every five years. This means 2020 was the year for the first round of revisions to commitments made in 2015 when the Paris Agreement was adopted.
