As Europe faces another scorching heatwave, the EU's Green Deal is under the microscope. This summer, the deal's effectiveness is being tested, as the extreme temperatures have brought both challenges and opportunities. The deal, unveiled in 2019, aims to reduce energy consumption, fossil fuel use, and greenhouse gas emissions, but the current heatwave has highlighted a critical issue: the need for adaptation. The EU's climate transition is facing a paradox as it grapples with the question of air conditioning. While the deal encourages electrification and renewable energy, the strain on the grid and the potential surge in electricity demand during heatwaves raises concerns. The debate revolves around whether air conditioning should be prioritized, especially in the face of rising temperatures and public health risks. The EU's climate policy is at a crossroads, with growing support for treating cooling as critical infrastructure rather than a consumer choice. The heatwave has exposed social inequalities, as wealthier households can afford cooling systems, while poorer families often endure dangerous indoor temperatures. This has sparked a class war, with the Green Deal's focus shifting from decarbonization to adaptation. The deal must now prove its ability to help Europe cope with rising heat, as the continent grapples with the urgent task of helping Europeans live with a changing climate.
