The survey, requested by Abbey Ward councillors, measured vehicle emissions on Bearwood Road between The Bear and the junction with Poplar Road, and used number plate recognition software and cctv to identify the most polluting vehicles.
Some of the report’s findings show that:
- Buses contributed 57% of NOx (nitrogen oxide) emissions in Bearwood Road despite making up only 6 percent of vehicle flow.
- Cars contributed 31 percent of NOx emissions although they are 86% of the vehicles in the street.
- 29 percent of buses are Euro 2 emission standard or older (i.e. over 10 years old) and the majority of buses are using technology at least 14 years old.
- Although the bus companies attribute emissions to Heavy Goods vehicles, only 1% of the traffic flow is comprised of HGV type vehicles.
For years the bus companies have argued that their vehicles do not contribute significantly to the pollution levels on Bearwood Road, but this report blows that argument out of the water.
