Analysis
Portugal recorded 2.79 million tonnes of CO₂ equivalents for nitrous oxide emissions in 2024.
Compared with earlier readings it is down 4.4% on the previous year and down 17.1% over ten years.
Over the whole period, nitrous oxide emissions in Portugal peaked at 4.99 million tonnes of CO₂ equivalents in 1979 and was at its lowest, 225,828 tonnes of CO₂ equivalents, in 1850.
That places Portugal 107th out of 201 countries with data for 2024, putting it in the middle of the range.
The series is highly variable year to year, so single readings are best treated with caution.
