In a major keynote speech at London Climate Action Week, the UN chief highlighted how the world’s dependence on oil is driving both the climate crisis and an energy sovereignty crunch, the latter linked to massive shipping disruption in the Strait of Hormuz and the war involving Iran, Israel and the United States. Tweet URL “These crises may seem separate but they share the same destructive origin: fossil fuels. And they demand the same answer: a fast, fair transition to clean energy and a surge in adaptation, resilience and climate justice for those already facing climate harm,” Mr. Guterres said, in a call for political leadership to push through global change akin to that required to phase out leaded gasoline and to ban chemicals that created a hole in the ozone layer. In brief: the UN plan for energy independence Cut emissions fast: emissions must peak now and reach net zero by 2050, including through a global push to curb methane pollution. emissions must peak now and reach net zero by 2050, including through a global push to curb methane pollution. Accelerate clean energy: renewables pick-up needs to continue, subsidies must end for fossil fuel projects and fossil fuel profits taxed to support vulnerable communities and the energy transition. renewables pick-up needs to continue, subsidies must end for fossil fuel projects and fossil fuel profits taxed to support vulnerable communities and the energy transition.

Earth’s tipping points It is more than a decade since world leaders agreed in Paris to limit global temperature rise to 1.5°C above pre-industrial levels, a remarkable show of international unity, led by the UN. Today, although that Agreement stands – and despite the US officially withdrawing for a second time in January this year – UN-backed scientists warn that average annual temperatures are likely to exceed that threshold in coming years. “Every fraction of a degree matters,” the Secretary-General insisted, as he forewarned of the irreversible damage to coral reefs unable to survive in too-warm waters, the melting ice sheets that threaten to reshape coastlines and displace millions, and the real possibility that some small island nations could disappear under the waves. Faced with this existential scenario, “the task before us is to strictly limit the overshoot, shorten its duration and bring temperatures down below 1.5°C as fast as possible”, Mr. Guterres maintained. ‘Mother of all energy shocks’ And while he pointed out that “any peace agreement is welcome and would bring much needed relief”, in reference to a 60-day pause in hostilities to allow ongoing Iranian-US talks in Switzerland, the UN chief noted that the Middle East crisis had unleashed “the mother of all energy shocks” comparable to the oil disruption of the 1970s and the full-scale Russian invasion of Ukraine. As damaging as the Middle East war has been for highly industrialized nations, the UN Secretary-General insisted that developing countries have been hit even harder “It is a debt shock, a food shock, a development shock”, he told the London audience. A just future from renewables “The good news is – unlike every past energy crisis – we now have a clear way out, a clean way out,” the Secretary-General continued. He noted that since 2010, the cost of solar energy has plummeted by almost 90 per cent, onshore wind by more than 70 per cent, and battery storage by 95 per cent. Renewables avoided more than the annual carbon dioxide emissions of the US, the EU and Japan combined, Mr. Guterres said, adding that clean energy investment now attracts almost twice as much as fossil fuels.
