The UK has ambitious, legally binding targets in place to significantly reduce emissions of the five most damaging air pollutants (Nitrogen Oxides, Sulphur dioxide, Ammonia (NH3), Primary particulate matter (PM2.5), and Non-methane volatile organic compounds) by 2020, and 2030. In 2019, we published the National Air Pollution Control Programme (NAPCP), which set out the technical analysis for how our policies would achieve these emission reduction commitments. In March this year, we published emission projections which indicate that we are now not likely to meet the 2020 target for NH3 and PM2.5. We are now in the process of revising the NAPCP and will set out the additional measures needed to bring the trajectory of emissions reductions back on track. The new NAPCP will capture the changing context brought about by wider policy commitments, like net zero. Future progress will continue to be evaluated, ensuring the government remains on track to deliver the required emission reductions.
