Portugal's aviation emissions up 19% since 2019, Zero says

The environmental association Zero says pollutant emissions from aviation in Portugal have risen by 19% since 2019. The group warns that plans to expand airport capacity in Lisbon and Porto could undermine efforts to decarbonise the sector. Zero also notes that Portugal still lacks an adopted roadmap for reducing aviation emissions, raising concerns about how growth in air traffic will be reconciled with climate goals.
