<aside> 💡 High-Level Description:

The Department for Environment, Food & Rural Affairs (DEFRA) of the UK has been a stalwart in environmental governance and establishing methodologies across various sectors. Within the car sector, DEFRA's methodology focuses keenly on providing robust and comprehensible metrics for carbon emissions. Recognizing the massive contribution of vehicles to the UK's carbon footprint, DEFRA's guidelines are tailored to encompass the diverse range of vehicles on the roads, from compact cars to SUVs.

DEFRA's approach not only accounts for direct emissions derived from fuel combustion but also considers the broader life-cycle emissions of vehicles, including manufacturing, maintenance, and disposal. Their methodology, backed by extensive research and consultation with automotive industry experts, provides a solid foundation for the UK's policy-making, encouraging sustainable car manufacturing and usage. Through DEFRA's efforts, consumers, manufacturers, and policymakers are better equipped to make environmentally conscious decisions regarding transportation.
