UK Car Manufacturers Boost Sustainable Production with Renewable Energy

The UK automotive sector is making significant strides in sustainable production, with a 36% increase in on-site renewable energy generation

The UK automotive industry is accelerating its shift towards sustainable production, with a remarkable 36% increase in on-site renewable energy generation in 2026. This surge in green energy adoption is part of a broader industry commitment to reducing carbon emissions and building eco-friendly manufacturing plants.

The Society of Motor Manufacturers and Traders (SMMT) revealed these findings in its 27th UK Automotive Sustainability Report. The sector’s on-site renewables generation reached an impressive 80.4GWh, enough to power more than 32,000 British homes for a year and eliminate around 14,000 tonnes of CO2 from production processes.

Green Energy Powers UK Automotive Manufacturing

UK vehicle manufacturers are at the forefront of sustainable production, with more than a third (36.5%) of their electricity now coming from green energy sources. This includes both on-site generation and grid-supplied renewable energy.

Additionally, the industry has achieved an impressive recycling rate, with over 93% of manufacturing waste being reused or recycled.

The push for sustainability extends beyond factory operations. The UK automotive sector is also expanding its range of zero-emission vehicles, with more than 160 models available and nearly half a million new battery electric cars registered in 2026. This growth in electric vehicle (EV) adoption is supported by a significant increase in automotive apprenticeships and trainee numbers, which have risen by almost a third to more than 6,000 roles.

Challenges in Scaling Renewable Energy Generation

Despite these achievements, scaling on-site renewables generation presents significant challenges. The process requires complex planning, substantial upfront capital, and grid reinforcements. The largest projects face connection waits of up to 15 years, which can hinder the industry’s progress towards net-zero emissions.

To overcome these barriers, the SMMT advocates for removing regulatory obstacles and streamlining the planning process. By enabling more factories to generate their own clean power, the UK can further reduce the embedded carbon in vehicles and strengthen its position as a competitive, low-carbon manufacturing hub.

Electric Vehicle Transition: Progress and Challenges

The UK’s transition to electric vehicles is gaining momentum, with June 2026 marking the strongest performance for the total new car market since 2019. This growth is driven entirely by electrified vehicles, reflecting the substantial investment by manufacturers in low and zero-emission models across various brands, segments, and price points.

Hybrids and plug-in hybrids accounted for more than a quarter of registrations, while battery electric vehicles (BEVs) reached a 30% share. However, BEV uptake remains below the 33% target set for 2026. To meet this goal, the industry must achieve a 40% BEV share for the remainder of the year, a target that raises concerns about market deliverability.

The issue lies not in industry commitment but in the cost of bridging the gap between natural demand and regulatory requirements. Manufacturers have already absorbed over £12 billion in discounts to stimulate demand, a strategy that cannot sustain a durable transition. The cost of compliance, including lost margins and reduced capacity to compete, is intensifying and poses a significant challenge for the industry.

As BEV targets increase to 38% for cars and 34% for vans in 2027, and further to 52% and 46% respectively in 2028, the need for a sustainable transition becomes even more critical. The industry must focus on creating demand to recover the billions invested in developing and producing these vehicles, ensuring the transition is commercially viable.

Heavy Goods Vehicle Market: A Mixed Picture

The heavy goods vehicle (HGV) market in the UK faced a challenging second quarter of 2026, with new registrations falling by 14.7%. This decline pushed first-half demand down by 8.9% to 18,158 units, as fleet operators grappled with economic pressures and business cost constraints.

Despite the 7% during the quarter. However, this represents a small volume increase, raising market share from 0.8% to 1.0% compared to the same period last year. Year-to-date, ZEV HGV volumes have fallen by 6.6%, highlighting the significant challenges in the sector’s transition to zero emissions.

Manufacturers are delivering a growing range of ZEV models, but uptake remains constrained by higher upfront costs and infrastructure challenges. Long waits for grid connections and limited public charging provision continue to hamper adoption, despite government support through measures such as the Plug-In Truck Grant and the Depot Charging Scheme.

To accelerate decarbonisation, the industry calls for faster grid connections, accelerated depot planning approvals, and a long-term national infrastructure strategy. These measures would help support uptake across a diverse sector and boost operator confidence, ensuring the UK’s HGV market can meet its sustainability goals.
