Overview

• Schleswig-Holstein places second and Mecklenburg-Vorpommern third in the new Länder ranking, with Hamburg at the bottom.
• The analysis scores states across renewable power, transport and mobility, land use and nature protection, and buildings and heat using concrete indicators such as renewables share, charging coverage, protected areas and heat-pump uptake.
• Category leaders vary: Schleswig-Holstein tops renewable electricity and exports green power at times, the city states lead transport, Brandenburg and the Saarland top land and nature, and Brandenburg leads buildings and heat.
• Baden-Württemberg ranks penultimate overall despite strong charging coverage and a high heat-pump share, while Hessen finishes 14th and the Saarland 13th due to weak building efficiency, slow heating progress and other gaps.
• WWF links its call for reliability to an ongoing federal Energiewende review led by Economics Minister Katherina Reiche, whose planned cost-focused reset has prompted warnings from environmental groups about a potential slowdown.
