Environmental guidance for your business in Northern Ireland & Scotland
Emissions from vehicle exhausts are a significant source of air pollution. Air pollutants in vehicle emissions include:
You should try to limit the vehicle emissions produced by your business as they may:
Emission limits
Make sure that your vehicles comply with emission limits and weight regulations. The exhaust emission standards are specified in the Ministry of Transport (MOT) vehicle test schemes. These MOT test schemes include exhaust emissions checks for all vehicles except:
The MOT vehicle testing schemes are operated by:
You can find exhaust emission limits per types of vehicles in the following links - or, if in doubt, contact the DVA in Northern Ireland or the DVSA in Scotland:
The DVA in Northern Ireland, and the DVSA in the rest of the UK, also carry out roadside checks, including the checks on exhaust emissions.
Air Quality Management Areas
Your local council monitors air quality in your area. If the air quality exceeds a certain threshold, it may declare an area to be an Air Quality Management Area (AQMA). Within an AQMA the council may test vehicles at the roadside and issue fixed penalties to drivers whose vehicles fail. Check out if you are in an AQMA:

Low emission zones
Some local councils are introducing low emission zones (LEZ) to reduce pollution in urban centres. These are areas where you may have to pay a daily charge if your vehicle doesn't meet certain emission standards or qualify for an exemption. Check with your local council, or in Scotland, also on the Low Emission Zones Scotland website, to find out if there are any low emission zones in your area:
Stationary vehicles
You must turn off your engine if your vehicle is stationary to reduce exhaust emissions and noise. You can be prosecuted or fined by some local councils if you leave your engine running while stationary.
Fuel efficiency and high emission standards
When buying new company vehicles, select models with high fuel efficiency and the highest emission standards both for air pollution and carbon dioxide emissions (CO2). You can find out the fuel efficiency of a vehicle from the Vehicle Certification Agency (VCA) or Society of Motor Manufacturers and Traders Ltd (SMMT):
You can benefit from tax breaks by buying low emission vehicles.

Alternative fuels and electric or hybrid vehicles
You can reduce your vehicle emissions and possibly reduce running costs by using alternative fuels, such as LPG, electric hybrids or full electric vehicles. See:
You can fit older vehicles with devices that reduce their emissions – for example diesel particulate filters. This can be a cheaper alternative to upgrading engines.
HM Revenue & Customs (HMRC) reward businesses that use cleaner, more fuel-efficient cars. Road tax and National Insurance Contributions (NICs) are linked to the car's exhaust emissions, particularly its CO2 emissions. You can get more details from the HMRC.

Driver behavioural changes for fuel efficiency
Service all your vehicles regularly.
Make sure tyres are correctly inflated.
Remove any excess weight by only carrying what you need. Remove roof bars and boxes when they are not needed.
Go on efficient driving programmes - for employees. Fuel efficient driving measures include:
Use air-conditioning and other electrical devices sparingly as this increases fuel consumption.
Monitor your fuel consumption to help detect problems early. Set monitoring systems for vehicle performance.
Pre-plan delivery routes to maximise the efficient use of vehicles.
Avoid using vehicles for short journeys. Encourage your staff to use public transport, cycle or walk.
Reduce the impact of necessary journeys by using less-congested routes, avoiding peak travel times and encouraging car sharing.
Energy Saving Trust has a smart phone app to track the fuel you use; if you have the information provided in mind and change your behaviour, this can save you money.
