Analysis
In 2024, year-on-year change in co₂ emissions in Portugal stood at -2.08 million tonnes.
That represents a change of up 32.8% on the previous year and down 921.8% over ten years.
Over the whole period, year-on-year change in co₂ emissions in Portugal peaked at 8.25 million tonnes in 1989 and was at its lowest, -5.84 million tonnes, in 2020.
That places Portugal 196th out of 215 countries with data for 2024, putting it in the bottom quarter.
The series is highly variable year to year, so single readings are best treated with caution.
