Europe’s efforts to shield itself from any Russian energy supply shock mean its green push will face a setback, at least for now.

The invasion of Ukraine is forcing Europe to tap all energy resources to help protect against potential gas stoppages from Russia, its biggest supplier, and cut its dependence on the country. Some of the region’s top economies plan to increase gas-import capacities, build new LNG terminals, stockpile more coal and reopen power plants that burn the dirtiest fossil fuel.

That will inevitably lead to more emissions in the short term, just as countries are targeting long-term cuts to pollution.
