BERLIN, 22 April 2026 — UN Climate Change Executive Secretary Simon Stiell has warned that surging fossil fuel costs linked to ongoing global conflicts are compounding economic instability and risking a period of “fossil‑fuel driven stagflation” that will hit vulnerable countries hardest, including Pacific island states. Speaking at the Petersberg Climate Dialogue in Berlin on Tuesday, Stiell described the moment as “perilous times,” saying recent wars have “locked‑in much higher fossil fuel costs for months and likely years to come, delivering a gut‑punch to every nation and billions of households.”
Stiell argued the impacts go beyond energy markets, warning higher fuel prices are “driving up prices, driving down growth, pushing budgets deeper into quagmires of debt, and stripping away governments’ policy options and autonomy.” He urged world leaders to treat climate cooperation as integral to stabilising economies as well as cutting emissions: “Climate cooperation is key to fending off the twin‑reapers of global heating and fossil fuel cost chaos.”
Highlighting what he framed as a turning point, Stiell said the global shift to clean energy “is now irreversible,” and stressed the need to convert diplomatic commitments into on‑the‑ground projects. “Negotiations are one — and they remain critical. Now, in this era of implementation – we must turn them into projects on the ground,” he said, calling for the Action Agenda to be elevated “to share centre‑stage with negotiations” as a vehicle for rapid deployment and investment.
Stiell pointed to finance as the linchpin, urging “far more finance flowing into developing countries” to modernise energy systems and boost resilience. He singled out methane cuts and food systems as priority areas — “Methane is an ultra‑potent greenhouse gas. Slashing emissions by 2030 will have a huge impact on putting the brakes on global heating” — and underscored the need for resilience measures such as early warning systems.
For Pacific nations already feeling the squeeze of rising fuel and food costs, Stiell’s warnings echo earlier regional alerts. Pacific policymakers have been cautioned to prepare for higher energy bills and supply risks after recent spikes in global oil prices tied to Middle East tensions; analysts have also flagged risks to fertiliser and food supply chains through bottlenecks such as the Strait of Hormuz. Fiji and other island states have long pressed for increased climate finance and a fair, funded pathway away from fossil fuel dependence — a stance reiterated domestically by leaders including Finance Minister Professor Biman Prasad in recent COP discussions.
Stiell framed the urgency in terms of the international accountability process: measurable progress is needed “so that by the second global stocktake at COP33, we are on track to meet the commitments made at the first.” His remarks at Petersberg aim to inject momentum into both implementation and funding debates ahead of the next major UN reviews, pressing wealthy nations and multilateral institutions to accelerate financing and tangible projects that bolster both the climate and economic security of vulnerable states.
