Harmful NOx emissions from trucks have halved in only ﬁve years, according to new government
statistics. Department for Transport ﬁgures show a 52% fall between 2013 and 2018 as haulage ﬁrms have upgraded to cleaner Euro 6 lorries.
The Road Haulage Association says that the trend is set to continue and projects that NOx emissions from HGVs will have reduced by more than 80% by the end of 2025.
But the Association in its NOx Emission Assessment warns that many operators face an uncertain future as local authorities press on with plans which will see hauliers charged up to £100 per day to enter clean air zones.
RHA chief executive, Richard Burnett says that efforts to improve air quality will fall short until they proportionately target sources of emissions. “The government is signing off poorly conceived measures which punish hauliers for local authority failures to keep emissions in check,” he said.
“But we’re leading the way – we’ve more than halved our NOx emissions in the last ﬁve years and this will only continue as ﬁrms upgrade their ﬂeets.”
Lorries and buses account for a small, declining proportion of NOx emissions according to National Atmospheric Emissions Inventory data.
Figures from 2015 show that the sectors were responsible for only 7.6% of NOx, whilst the share from other key sources such as ‘passenger cars’ and ‘combustion in industry’ were much higher.
