Hong Kong to update air-quality plan, with city’s power companies facing lower emissions targets from 2026

Hong Kong’s two power companies will have to further reduce emissions of key air pollutants from 2026 onwards, with the city expected to release updated blueprints to tackle air quality issues and climate change by the second half of this year.

On Thursday, the government approved new caps on emissions of sulphur dioxide (SO2), nitrogen oxide (NOX) and respirable suspended particles (RSP), reducing the three pollutants by 9 per cent, 10 per cent and 6 per cent, respectively.
