Why air quality is important Help Improve Air Quality Air quality in rural Somerset is very good, but less good in the towns where traffic congestion and still weather can combine to cause localised health-damaging pollution. You can help to minimise these problems in how you choose to travel, what fuel type you choose for motor vehicles, and even how you drive. See the toolkits from our friends at Clean Air Day for schools, workplaces and communities to find out more.
