The reason for this is that the use of diesel creates emissions of nitrogen dioxide and fine soot (particulate matter), more so than from petrol engines, that if not reduced or controlled are known to cause significant chronic health problems such as respiratory diseases and cancer.

Moreover, poor air quality has a disproportionate impact on those who are most vulnerable in society, including children, those with pre-existing conditions and the elderly.

All of these factors have led to many organisations such as the GLA, National Highways, HS2 to stipulate specific requirements for the road going and non-road going vehicles used on their projects. Many UK cities now similarly have ‘Low Emissions Zones’ and ‘Clean Air Zones’ to reduce emissions of air pollutants. Understanding the key issues associated with poor air quality, and what your organisation can do to reduce its air quality impacts is likely to have key benefits for your business, as well as wider community benefits in the places you work.

Of course, switching fuel and power source to an alternative with lower emissions is the goal for both air quality and climate change impacts – hybrid, battery, hydrogen…

The School Plant Category Group focuses on minimum engine emission standards, as well as operator behaviour. Have a look at the Plant Commitment Charter for more information and how to get involved.
