Greve Municipality has set the ambitious goal of achieving net-zero CO2 emissions and climate resilience by 2050 at the latest, with significant milestones of 49% reduction by 2025 and 75% reduction by 2030. As a DK2020 municipality, Greve commits to leading the way in the green transition, and the plan's origin in the country's first climate citizens' assembly in 2022 underscores the municipality's focus on citizen-centred climate work. The municipality's total CO2 emissions amounted to 246,000 tonnes in 2019, reflecting Greve's character as a commuter municipality with close links to the capital region. The geographic location along Køge Bugt creates both challenges and opportunities - from the risk of storm surges to potential for sea-based CO2 storage through eelgrass projects. Particularly notable is that 68% of CO2 emissions from heat consumption come from private households, where 84% of this share comes from natural gas. Greve's climate challenge is shaped by the municipality's dual character as both a coastal municipality and a suburban area. The shortage of groundwater resources combined with a growing population and climate change creates a complex picture where climate adaptation and CO2 reduction must be considered together. At the same time, the municipality's position between land and sea offers unique opportunities - from afforestation projects such as Greve Skov and Tune Skov to experimentation with eelgrass as a CO2 store in Gate21's Power Bio project. The most comprehensive planned measures focus on phasing out fossil fuels for heating, where the municipality is working purposefully to convert from oil boilers and natural gas boilers to district heating or heat pumps. Greve Fjernvarme's plan for converting 2,000 households east of the motorway constitutes the first phase, while VEKS is simultaneously working on fossil-free district heating by 2025. In parallel, the focus is on electrification of the transport sector, where the municipality has already decided to convert three bus routes to electric operation and developed a charging station strategy with a minimum of 27 public charging points. Despite the plan's comprehensive package of 53 concrete measures, calculations show a shortfall of 8,861 tonnes CO2 in 2030 and as much as 21,208 tonnes in 2050. This underscores that even ambitious municipal climate plans encounter the limits of what can be solved locally. The challenge of scope 3 emissions from consumption and material use in particular requires national solutions and technological development that the municipality cannot directly influence. Citizen and business engagement forms the backbone of Greve's climate strategy, from the annual Climate Action Day to cross-cutting collaboration with housing associations and homeowner associations. Frivilligcenter Greve's role as a central partner in the green association transition and the planned collaboration with local businesses on climate partnerships show how the municipality recognises that climate targets can only be reached through collective efforts across the entire local community.
