The UK's journey towards a greener future took a significant step forward in 2025, with a notable decline in greenhouse gas emissions. This progress is not just a one-off; it's part of a consistent trend that has seen emissions fall in 27 of the last 36 years since 1990. What makes this particularly interesting is the context: despite record-high temperatures and elevated gas prices, the UK managed to reduce its emissions to levels not seen since the Victorian era.
One of the key drivers of this reduction was the dramatic fall in coal and gas usage. Coal, in particular, experienced a remarkable decline, dropping to levels last seen in 1600, during the reign of Queen Elizabeth I. This decline was primarily due to the phase-out of coal-fired electricity generation and a slowdown in the steel industry. The UK's last coal-fired power plant, Ratcliffe-on-Soar, closed its doors in 2024, contributing significantly to the reduction in coal demand.
Gas usage also hit a 34-year low in 2025, with demand similar to the early 1990s when the UK began its 'dash for gas'. This period saw a wave of new gas-fired power stations, but now, gas demand has fallen by nearly two-fifths since 2010. The reasons for this decline are multifaceted, including more efficient gas boilers, improved insulation, and, of course, the record-high temperatures and elevated gas prices of 2025.
The transport sector also played a role in the UK's emissions reduction. Despite rising traffic levels, oil use fell by 0.9% year-on-year, thanks in part to the growing number of electric vehicles (EVs) on the nation's roads. By 2024, there were nearly 3 million EVs, plug-in hybrids, or electric vans, which is cutting UK emissions by more than 7 MtCO2 annually. This shift towards electrification is not just environmentally beneficial; it's also financially rewarding for drivers, with EV owners saving significantly on fuel costs compared to petrol or diesel vehicles.
However, it's important to note that the UK's progress is not without its challenges. While emissions have fallen to 54% below 1990 levels, the country still has a long way to go to meet its future climate goals, including the seventh 'carbon budget' and the 2050 net-zero target. To achieve these ambitious targets, emissions would need to fall by an average of 15 MtCO2e each year until 2050.
In conclusion, the UK's emissions reduction in 2025 is a significant milestone, but it's just one step on a longer journey towards a sustainable future. The decline in coal and gas usage, coupled with the rise of EVs, is a promising sign, but continued effort and innovation will be needed to meet the country's climate commitments. As we move forward, it's crucial to maintain this momentum and explore new ways to further reduce emissions and mitigate the impacts of climate change.
