UK vehicle makers are accelerating investment in sustainable production with on-site factory renewable energy generation rising by more than a third last year to reach record levels, according to new analysis from the Society of Motor Manufacturers and Traders (SMMT).

The 27th UK Automotive Sustainability Report shows the sector’s on-site renewables generation rose 36 per cent to 80.4GWh in 2025. The analysis, representing manufacturers of 99.7 per cent of all UK-built cars and commercial vehicles as well as the wider supply chain, reflects industry investment to cut carbon, reduce resource use and build greener plants for greener vehicles.

In addition to renewables generation, more than a third (36.5 per cent) of all industry’s electricity was supplied through green energy from the grid last year, while more than 93 per cent of manufacturing waste was reused or recycled.

Mike Hawes, SMMT chief executive, said, “The UK automotive industry is investing significant amounts to try and remain competitive, innovating to decarbonise from well to wheel and creating greener factories for greener vehicles in every nation of the UK. But ambition alone cannot deliver sustainability at the pace needed. Manufacturers need faster connections, more low-carbon power and energy costs that are internationally competitive.”
