UK Prime Minister Keir Starmer’s speech at COP30 in Belém, Brazil, delivered an emphatic message: the UK is “all in” on the fight against climate change, reaffirming its commitment to net zero, ambitious clean energy investments, and global climate cooperation. Addressing world leaders at a defining moment for global climate diplomacy, Starmer declared the “consensus is gone” on climate action, but stressed that the UK would double down rather than retreat, positioning the nation at the forefront of the clean energy revolution.

The opening session of COP30 in Belém, Brazil, launched a pivotal moment in global climate diplomacy as world leaders, diplomats, and experts assembled on the edge of the Amazon rainforest to address the planet’s escalating climate challenges. The event emphasized that COP30 represents not only a key milestone—marking 30 years since the first Conference of the Parties (COP)—but also a make-or-break moment as nations face mounting climate-related disasters, record-breaking temperatures, and surging energy demands.

In October 2025, the UK government revealed the eagerly anticipated Carbon Budget and Growth Delivery Plan, a comprehensive roadmap detailing how the nation will meet its statutory carbon budgets and revitalise momentum towards the 2050 net zero target. This new initiative comes after a period of concern around missed milestones and responds directly to legal and advisory pressures, including a High Court ruling that mandated clearer plans for achieving emissions reductions. The plan provides much-needed clarity for investors, businesses, and communities, anchoring delivery in real-world action and transparent policy commitment.

For the first time ever, global greenhouse gas emissions are projected to fall within the next decade, according to the latest United Nations analysis. After decades of relentless growth—including record highs set just last year—new national pledges, combined with rapid investment in clean energy, have begun to bend the emissions curve downward. The UN Framework Convention on Climate Change (UNFCCC) now expects about a 10% reduction by 2035, compared with 1990 levels—though this is far short of the 60% cut scientists say is required to keep global warming below the critical 1.5°C Paris Agreement threshold.

Great British Energy, backed by the UK government, has announced a £30 million investment into 34 NHS trusts to accelerate solar panel deployments across England. This project is an integral part of a wider sustainability strategy, expanding the successful solar rollout to around 70 new healthcare sites and scaling NHS solar generation nationwide. As the single largest public-sector energy consumer—with annual bills topping £1.3 billion—the NHS now has a crucial opportunity to slash costs, future-proof its infrastructure, and reinvest millions in direct patient care.

The latest data from the Department for Energy Security and Net Zero (DESNZ) underlines a striking statistic: 76% of the UK public now support the development of solar energy projects. This massive groundswell of approval is not only a testament to the positive perception of renewable energy but also signals a broader shift in attitudes across the country, with solar PV at the heart of Britain’s clean energy transition. According to the DESNZ Public Attitudes Tracker (Spring/Summer 2025), overall support for solar energy as a key electricity source is among the highest of all renewables, consistently outpacing wind and biomass at 86% overall support when asked more generally.

In 2025, renewable energy is undergoing its most transformative period since the dawn of the clean power revolution. Global investment in renewables surpassed £1.7 trillion this year, with new technologies redefining efficiency, affordability, and scalability. From artificial intelligence in grid forecasting to next-generation solar cells, emerging solutions are enabling a cleaner, smarter, and more resilient energy future.

According to two new United Nations reports released in July 2025, the world has officially passed a “positive tipping point” in the shift to renewable energy. UN Secretary-General António Guterres hailed the milestone as a defining moment, announcing that “the fossil fuel era is flailing and failing” as solar and wind power dominate new global electricity capacity. Together, renewables accounted for over 92% of new electricity generation added to the global grid in 2024—an unprecedented record that confirms clean energy’s irreversible momentum.
