U.S. and European officials pushing for tougher climate action are worried the energy crunch that’s snarling the global economy could also undermine crucial United Nations talks next month.

Government officials speaking on condition of anonymity said they were concerned that the squeeze in energy markets, surging prices, and the resurgence of coal will cast a shadow over efforts to curb emissions when 197 countries meet at the climate change summit, known as COP26, in Glasgow, Scotland.

The risk is that the price spike makes emerging economies — for example India — more reluctant to ditch coal because that would threaten energy security, three government officials said. Whereas countries like the U.K. have tried to use gas as a so-called "bridging fuel” as they shift to lower-carbon options, the surge in prices makes that option less palatable — at least for now. The crisis has also thrown into sharp relief the volatility that can accompany renewable energies.
