How can nitrogen oxides (NOx) emissions of hydrogen internal combustion engines (ICE) technologies be minimised and what is the lowest it could be?

Background

Tackle climate change and improve air quality by decarbonising transport. Transport is the largest emitting sector of greenhouse gases (GHG) in the UK, contributing 27% of domestic emissions in 2019. Our transport system must change to deliver the Government’s Net Zero ambition and DfT will drive forwards that change through our longer-term green transport agenda. Sustainability will be at the heart of levelling-up. People everywhere will feel the benefits - villages, towns, cities and countryside will be cleaner, greener, healthier and more prosperous and pleasant environments in which to live and work.

Key areas of focus are:
• Decarbonisation of road vehicles
• Accelerating modal shift to public and active transport
• Decarbonising how we get our goods
• Place based solutions and environmental impacts
• UK as a hub for green transport, technology and innovation
• Reducing carbon in a global economy

The Transport Decarbonisation Plan (TDP) sets out the steps we will take to deliver the necessary carbon reductions across every form of transport. DfT's progress towards a decarbonised transport system has a vital role in delivering net zero across the wider economy by 2050 and science, engineering, innovation and research are essential in driving this change.
