I was shocked recently to read about the extent of air pollution in Bolton and across Greater Manchester.

Pollution from road traffic has been linked to a range of serious health issues. Young children who are regularly exposed to air pollution can face a lifetime of lung problems. Even low levels of pollution can make children have asthma attacks.

It is estimated that pollution from road traffic contributes to 1,200 deaths a year across Greater Manchester. A major factor is the amount nitrogen dioxide produced when fuel is burned. Diesel vehicles are the largest source of nitrogen dioxide.

I was pleased to see that under the leadership of Greater Manchester Mayor, Andy Burnham, local councils are working together to clean up the air we all breathe. Clearly there are lots of steps that can be taken to make a difference.

Better investment in our buses and trains could make a massive difference. All too often people face unreliable buses and overcrowded trains. For those who rely on cars to get around our roads are often heavily congested, especially at peak times. Better public transport would benefit everyone.

Businesses which rely on diesel vehicles will need a great deal of support to help switch to more environmentally friendly vehicles. This may take time and money but will be worthwhile to benefit everyone.

Reducing the amount of nitrogen dioxide in the air will tackle air pollution and improve the quality of the air that we all breathe. Hopefully this will contribute to the fight against climate change too.
