Simon Stiell: Fossil fuels drive cost crisis, clean energy is the solution

Fossil fuel dependency rips away countries' sovereignty and security, putting food prices, household budgets, business bottom lines, and entire economies at the mercy of geopolitical shocks, Executive Secretary of the United Nations Framework Convention on Climate Change (UNFCCC) Simon Stiell said in a statement, Report informs.

"War in the Middle East has exposed a brutal truth: fossil fuel dependency rips away countries" sovereignty and security, putting food prices, household budgets, business bottom lines, and entire economies at the mercy of geopolitical shocks. In a world of 'might is right' politics, that gets more volatile every month, the costs of fossil fuel subservience are spiralling out of control," Stiell says.

According to him, the latest conflict has unleashed what the International Energy Agency has called, "the greatest global energy security threat in history", constricting oil and gas supplies and sending prices soaring.

"Inflation inevitably follows, with higher bills for families and businesses of all sizes. The impacts are reverberating around the world. [Regional specific example of impacts.] The World Food Programme predicts that the war could push global hunger to record levels this year," reads the statement.

"Incredibly, however, some argue that the correct response to the current crisis is to slow the shift to renewable energy, and instead double down on the cause of the turmoil – fossil fuels. This defies economic logic and basic common sense. With geopolitics in disarray, energy price chaos will keep happening again. Continued dependence on fossil fuels would leave countries forever lurching from crisis to crisis," says Stiell.

"It would also mean our planet keeps heating up, supercharging climate disasters like mega storms, droughts, fires and floods," he adds, noting: "These are already ruining millions of lives and tearing shreds out of every economy, including [country]. [Regional examples of cost/disruption of climate impacts.] If temperatures keep rising unchecked, this will only get worse. And yet the cause - fossil fuels - continues to receive trillions of dollars in subsidies globally."

According to Stiell, the good news is there is a clear solution to both the climate crisis and the fossil fuel cost crisis: accelerating the shift to clean energy systems – where renewables supply the power, backed by modern grids and storage, and clean technologies, like electric vehicles, replace polluting alternatives.

He further notes: "Sunlight and wind don"t depend on narrow and vulnerable shipping straits. Clean energy like solar and wind power - allow nations to regain control of their economies and security; insulating their countries from global turmoil, while creating jobs, cutting pollution, improving health, boosting stability, and lowering costs. Renewable power is the cheapest there is. [In China, electric vehicles are set to avoid over $28 billion a year in oil import costs. OR other regional example of benefits.]"

Many countries are already seizing these benefits and protecting themselves from climate disasters, he says. "But others need support. Over $2 trillion flowed into clean energy last year – twice as much as fossil fuels – but very little went to the vulnerable developing economies that need it most."

He warns that it must change urgently. "Richer countries – and the international financial institutions they control – have every incentive to ensure that affordable finance flows to developing nations for climate action. Because a truly global shift benefits us all. In our interconnected global economy, climate disasters hammering supply chains are a major inflation driver for every country. But through international climate cooperation, countries are creating an alternative to the strong-arm politics dominating international affairs."

"At UN Climate Change, we're supporting this cooperation. Our annual conferences, known as COPs, have driven major progress – roughly halving the projected rise in global temperature, transforming global energy markets and supporting resilience-building. But we need to go far faster, and to ensure a just transition, including for economies and communities that have historically relied on fossil fuels.

The quicker countries move, the greater the gains, and the climate cannot wait. So, we're increasingly focused on turning climate commitments into real-world outcomes that benefit billions more people. COP29 in Azerbaijan produced a headline achievement with the adoption of a $300 billion annual target for developing countries by 2035 under the New Collective Quantified Goal. Last year at COP30 in Brazil, $1 trillion was committed to grids and storage, to invest in modern, clean energy systems. This year's COP31 in Türkiye will drive further progress across sectors and regions," Simon Stiell says.
