BERLIN — UN Climate Change Executive Secretary Simon Stiell has warned that global conflicts are driving up fossil fuel prices and plunging economies into what he called “fossil‑fuel driven stagflation,” a development he says is compounding climate risks and deepening economic fragility for countries around the world — including vulnerable Pacific islands.
Speaking at the Petersberg Climate Dialogue in Berlin on Tuesday, Stiell said “this latest war has further 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.” He warned the economic fallout from sustained high fuel prices is “driving up prices, driving down growth, pushing budgets deeper into quagmires of debt, and stripping away governments’ policy options and autonomy.” Stiell framed stronger climate cooperation as central to addressing both economic instability and the accelerating impacts of global heating.
Stiell used the platform to press for urgent, measurable implementation of climate pledges. While he acknowledged that negotiations remain critical, he said the era now demands “projects on the ground” and elevated emphasis on the UNFCCC’s Action Agenda, which he said has been “mobilizing trillions of dollars within the real economy” and is helping make the clean energy transition “irreversible.” “Clean energy offers security and affordability — returning sovereignty to nations and their peoples,” he said, arguing that speedier deployment of renewables would lessen exposure to volatile fossil fuel markets.
The UN official singled out developing countries as a priority for increased investment, calling for “far more finance flowing into developing countries” to support energy system transformation, resilience and food systems. He identified a short list of priority actions, notably slashing methane emissions by 2030 — a measure he said would have a rapid and outsized impact on slowing near‑term warming — and scaling up resilience measures such as early warning systems that “save lives on a huge scale.”
Stiell also set a political benchmark: negotiators must deliver tangible results ahead of the second global stocktake at COP33, turning commitments agreed in recent rounds — including the landmark pledges recorded at COP28’s first global stocktake — into real‑world outcomes and infrastructure. His appeal echoed comments by UN Secretary‑General António Guterres, who at the same forum urged countries to “unleash the renewables revolution,” reinforcing the UN’s push for rapid decarbonisation paired with finance and implementation.
For Pacific island nations, the warnings carry immediate resonance. Delegates from the region have been raising alarms about rising import and fuel bills, and recent analyses warned the Iran‑related conflict risk premium on oil markets could sharpen the squeeze on small island economies. Fiji and other Pacific leaders have repeatedly framed the energy transition as an issue of climate justice and economic security, calling in earlier forums for greater climate finance to enable a shift away from costly fossil fuels.
Stiell’s message tightens the linkage between geopolitics, energy markets and climate policy and places a new emphasis on delivery: not only committing to decarbonisation, but rapidly financing and building renewable systems, cutting short‑lived climate pollutants like methane, and investing in resilience to shield the world’s most vulnerable from both the economic and environmental shocks of today.
