Vienna is pursuing climate neutrality by 2040, a mandate established by the Vienna Climate Law in March 2025. Central to this transition is the “Raus aus Gas” (Out of Gas) program, which aims to phase out fossil gas and replace over 400,000 decentralized gas heating systems with geothermal energy, large-scale heat pumps, and renewable-based district heating.

To support this shift, the city is expanding local electricity generation via photovoltaics, advancing e-mobility, and exploring green hydrogen. To manage rising electricity consumption and imports, officials are focusing on improving distribution systems and ensuring grid stability through capacity markets and reserve power plants.

In a recent update to its climate roadmap, the city has expanded its strategic focus to include managing the impacts of heat and drought. While the 2040 neutrality goal remains the core objective, new priorities include stabilizing the drinking water supply, strengthening regional agriculture, and expanding natural recreational spaces. The updated roadmap also includes a redesigned heat action plan to manage extreme temperature periods and seeks to sharpen definitions for climate justice and neutrality. This legally mandated review, which occurs every five years, coordinates efforts across sectors such as mobility, construction, and the circular economy.
