In the Paris Agreement under the United Nations Framework Convention on Climate Change (UNFCCC), governments agreed to the long-term target of keeping the increase in global average temperature to well below 2 °C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C. 

Under the Paris Agreement, countries agreed to periodically update their Nationally Determined Contributions (NDC) over time, by an iterative process in 5-year intervals and, if possible, increasing the ambition of the previous NDC1.

By the end of June 2021, Montenegro, the other Energy Community Contracting Parties (Albania, Bosnia and Herzegovina, Kosovo2, North Macedonia, Georgia, Moldova, Serbia and Ukraine) and the EU (including 27 EU Member States) had updated their NDC2.0, all including emissions and removals from land use, land-use change and forestry (LULUCF) except Montenegro3. In 2025, Parties to the Paris Agreement are submitting the NDC3.0 with a 2035 target.

During 2024, Montenegro has updated its NDC3.0 and submitted it to the UNFCCC on 21 February 2025. As a Contracting Party of the Energy Community Treaty, an European Union (EU) Candidate Country, signatory to the Sofia Declaration, and actively committed Party to the UNFCCC and the Paris Agreement, in its updated NDC3.0, Montenegro aspires to comply with EU acquis and the EU climate change law and aims to increase its climate ambition to a 55% net greenhouse gas (GHG) emission reduction target by 2030 and to a 60% by 2035 compared to 1990 levels.
