Over the last 10 years, the average weight of vehicles sold has increased by about 9% or around 100 kgs. Sales of small SUVs have increased 5 times, becoming the most sold vehicles in 2022 with about 4 million new units put on roads across Europe. Large SUV sales have also further increased by 7 times, although the total sales volume is roughly 700,000 units.

Considering the impact of weight on consumption and on greenhouse gas emissions (GHG) and primary energy demand (PED) for production, a compact family car – with a 100 kg average increase in weight – is responsible for about 1.4 tonnes of additional greenhouse gas emissions and 5.7 MWh of extra energy used.
