The UK Foreign Secretary, speaking at New York Climate Week's Opening Ceremony on 21 September 2026, asserted that climate breakdown and nature loss constitute an urgent national security issue. The Secretary, who previously served as Energy Secretary, highlighted the need for a change in how these issues are perceived and addressed within government.
The Foreign Secretary noted that in 2026, clean energy investment is projected to reach $2.2 trillion globally, compared to $1.2 trillion in fossil fuels. The speech also referenced the UK's recent nature security assessment, which concluded that ecosystems are being degraded worldwide.
The UK has enacted carbon budgets aiming for an 87% reduction in emissions by 2040, consistent with a 1.5-degree target. Additionally, the government has announced an intention to invest £400 million in the Tropical Forest Forever facility to support international efforts in protecting tropical forests. The UK is also pursuing a clean power plan for a clean power system by 2030.
