While we've focused on traffic and industry for air pollution control, a surprising source has emerged: home heating.
Homes in the UK now produce more particle pollution from wood and coal burning than vehicles on the roads.
This has led to calls for stricter regulations on stove sales, with experts advocating for cleaner burning practices instead of outright bans.
The focus is shifting towards educating homeowners about the impact of their fires on air quality and encouraging voluntary changes in behavior.
