In 2021, Portugal's carbon footprint was 51.9 kilotons of carbon dioxide emissions, equivalent to 5.0 tons per capita, 25.3% less than in 2010.

Half of the emissions were emitted in Portugal (15.2% from households and 34.8% from production activities due to domestic demand), while the other half were emitted abroad (19.3% in EU Member States and 30.7% in other countries).

The EU's carbon footprint is higher than that estimated for Portugal (on average 1.5 times higher, or 2.8 tons more per capita), although the reduction since 2010 is less marked than in Portugal (-18.7%).   

Outside the EU, China was the country that contributed the most to the national carbon footprint (7.4% of the total).
