Briefings

A 2026 study found that total emissions of harmful air pollutants from cooking in London and Beijing are lower than those from vehicle exhausts. This finding challenges the assumption that transport is the primary source of air pollution in these megacities, suggesting that home cooking may be a more significant contributor to air quality issues in these specific urban centers.

Key points

• Total emissions from cooking in London and Beijing are lower than vehicle exhausts.
• This study found that cooking emissions are the primary source of harmful air particles in these cities.

Context

Decades of regulations and a shift toward less polluting road transport have reduced vehicle emissions in London and Beijing. However, this study reveals that cooking remains a major source of air pollution in these megacities.

Limitations

The study covers only London and Beijing centers. Results are based on a single study from 2026 with no additional background or context provided.
