Somerset winter gritting overhaul cuts carbon with route specific forecasts, earns national award shortlist

Somerset Council and Kier have been shortlisted for the Net Zero Project of the Year at the 2026 Department for Transport Special Recognition Awards for a winter road maintenance project that cuts carbon while keeping roads safe. The new approach replaces four broad forecast areas with 23 route specific weather assessments, so gritting and salt treatment only happen where they are actually needed. The project, developed through the DfT funded Live Labs 2 programme, cut combined fuel and salt emissions by 70,867 kgCO2e in the 2026/27 season, according to the council. It took less than nine months to move from concept to implementation across Somerset's 6,765 km road network, of which about 1,450 km is treated in winter. Targeted gritting of this kind is a practical example of how local authorities can reduce emissions and operating costs without compromising highway safety. The winners are announced later this month in Blackpool.

Nice to see a local council project get recognition for actually cutting emissions. The 70,867 kgCO2e saving is from one season, but the real shift is going from 4 forecast zones to 23 route specific ones. That means fewer miles spread, less salt, and no drop in safety. Worth a read.

The carbon number is small but the operational change matters. I'd want to know how they validated the 70,867 kgCO2e figure, and whether the route forecasts held up during the worst storms. Also curious if this scales beyond Somerset, since most councils run similar winter ops.

Live Labs 2 was a DfT funded programme to test low carbon highways tech, so this is one of the pilots turning into business as usual. Nine months from concept to implementation is the impressive part. The open question is whether the carbon accounting includes the full lifecycle of salt production and spreading.

Route based forecasting is a low cost way to cut emissions, not flashy but it adds up. 23 zones instead of 4 means decisions follow local conditions, so you avoid treating roads that don't need it. I'd like to see the fuel and salt breakdown behind the 70 tonne figure.

Good example of using data to cut waste in a public service. The article doesn't say how much fuel and salt were saved separately, only the combined carbon number. That kind of detail would help other councils compare their own winter ops.
