UK Warming, Wildlife Loss and Lower Energy Use: What the ONS Environment Review Tells Us

The Office for National Statistics has published a sweeping annual overview of the UK’s environment, climate and nature, drawing on official statistics to map where progress is being made — and where serious pressures remain.

What the ONS Has Published

Picture the UK’s environmental story laid out in a single document — temperatures, species counts, energy bills, carbon output — and you’ve got a sense of what the ONS has just released. The article, titled *Beyond GDP Insights – Environment, Climate and Nature, UK: 2025*, brings together economic, environmental and social statistics to give a broad picture of where Britain stands on climate and nature. It’s not a policy announcement. It’s the data.

The ONS posted the overview this week, describing it as an annual review of UK progress from an environmental, climate and nature perspective.

The Temperature Numbers Are Hard to Ignore

The UK climate has been warming at around 0.25°C per decade since the 1980s, according to the ONS, citing the Met Office’s *State of the UK Climate 2024* report. And it’s not just a long-term trend — 2022, 2023 and 2024 were all among the five warmest years ever recorded in the UK. Three of the top five, back to back.

People are feeling it. In a survey covering 3 September to 26 October 2025, adults across Great Britain were asked how climate change had affected them in the previous twelve months. Heatwaves came out on top, with 55% of respondents saying they’d been affected. Strong winds were reported by 38%, and drought by 26%.

Nature Under Pressure

The wildlife picture is sobering. The UK’s priority species abundance index — a measure tracking the health of species considered most at risk — had fallen to just 37% of its 1970 baseline by 2021. So we’re talking about populations sitting at barely over a third of where they were half a century ago. The ONS notes the index has been relatively stable since 2016, but that stability comes from a very low starting point.

Natural England’s own analysis of the State of Nature report puts average species decline at about 19% since 1970, with 16.1% of UK species now threatened with extinction.

Where Progress Is Showing Up

But it’s not all bleak. Energy use is down — domestic electricity consumption across Great Britain fell by 19% between 2005 and 2023, and gas consumption dropped by 31% over the same period. That’s a meaningful shift in how households are using energy.

The UK’s emissions intensity has also fallen sharply. In the second quarter of 2025, the figure stood at 141 tonnes of CO2 equivalent per million pounds of gross value added — down 64% from 389 tonnes back in 1999. The economy is producing less carbon per pound of output than it was a generation ago.

UK natural assets were valued at £1.634 trillion in 2022, delivering an estimated £47.6 billion in annual benefits. Woodlands alone removed 18 million tonnes of CO2 equivalent in 2022, valued at £5.1 billion. Urban nature helped cut heatwave costs by £820 million in the same year.

The Bigger Picture

The ONS frames this as a statistical overview rather than a verdict on government policy. But the numbers sit alongside legally binding targets under the Environment Act 2021, which commits the UK to reducing emissions and reversing biodiversity loss. Whether the data shows those targets are on track is a question the article leaves to policymakers and the public to weigh up.

Jil Matheson, the National Statistician whose office oversees this kind of reporting, has described the ONS’s broader *Beyond GDP* work as an effort to measure national progress in ways that go beyond economic output alone — capturing wellbeing, environment and sustainability alongside traditional financial indicators.

Key Takeaways

• The UK has warmed at roughly 0.25°C per decade since the 1980s, with 2022, 2023 and 2024 all ranking among the five warmest years on record
• UK priority species abundance stood at just 37% of its 1970 baseline by 2021, with 16.1% of UK species now threatened with extinction
• Domestic gas consumption fell 31% and electricity use dropped 19% between 2005 and 2023, while UK emissions intensity is down 64% since 1999

What This Means for Kent Residents

Kent sits at the sharp end of many of the pressures the ONS review describes. The county’s long coastline makes it above all exposed to the effects of warming seas and coastal erosion, while its position as one of England’s driest counties means drought — reported by more than a quarter of UK adults as a climate impact they’ve already felt — is a real and growing concern for households, farmers and water suppliers alike. Hotter summers are already affecting how people live and work here, and local authorities across Kent are increasingly factoring heat and flood risk into planning and infrastructure decisions. If you’re a homeowner or business owner, it’s worth looking at your energy use — the national trend towards lower consumption shows what’s possible, and schemes supporting home insulation and renewable energy are available through local councils and the government’s Great British Insulation Scheme. For anyone concerned about local nature and biodiversity, organisations including Kent Wildlife Trust run volunteering and habitat restoration projects where residents can get directly involved.
