Climate change is one of the most significant global challenges. According to the Climate Act, Finland's goal is to achieve carbon neutrality by 2035. The law sets three emission reduction targets: a 60% reduction in greenhouse gas emissions by 2030, 80% by 2040, and 90%, aiming for 95%, by 2050 compared to 1990 levels. This goal will be pursued by accelerating emission reduction actions and strengthening carbon sinks. The municipalities and companies of Central Ostrobothnia have a significant role in mitigating climate change. The transition to a carbon-neutral society is challenging but also provides a foundation for sustainable growth for municipalities and businesses. Although municipal organizations themselves account for only about 10% of the region’s greenhouse gas emissions, with other actors accounting for the remaining 90%, municipalities have a key role in climate mitigation. A sustainable future requires broad collaboration, with municipalities encouraging other local actors to engage in climate action. One solution for reducing municipal emissions is collaboration between municipalities and businesses. Companies play a crucial role in climate work through innovations, operational changes, and value chain cooperation. The aim is to involve local businesses in climate efforts, as cooperation between companies and municipalities moves the region closer to carbon neutrality. This collaboration also fosters regional clusters where materials and production by-products are efficiently recycled and utilized. Thus, cooperation between municipalities and businesses is vital for a vibrant and sustainable community. The project addresses the challenges in Central Ostrobothnia related to achieving emission reduction targets, energy efficiency requirements, and sustainability reporting. Current methods are insufficient, and broad cooperation between municipalities, businesses, and stakeholders is essential. In addition, SMEs and municipalities lack sufficient knowledge and concrete tools to implement climate responsibility and meet sustainability requirements. The project supports the transition from a linear economic model to a circular economy, while enhancing business competitiveness and sustainable growth. The project addresses a recognized need for development and aims to solve the following issues: achieving carbon neutrality and promoting cooperation, providing information and support for businesses and stakeholders on sustainability, and advancing circular economy-based business models and competitiveness. The main goal of the project is to support Central Ostrobothnia's carbon neutrality target by strengthening collaboration between various stakeholders, including micro and SMEs, municipalities, R&D organizations, and the third sector. This will be achieved by improving companies' energy and material efficiency and providing information and support on concrete emission reduction measures and calculation models. Additionally, the project will offer easily accessible, up-to-date information on various aspects of sustainability—environmental, social, and economic responsibility—and circular economy. In doing so, it supports the region’s sustainable future development and helps businesses and municipalities navigate changes. A third goal is to promote the shift from a linear economic model to a circular economy, fostering cross-sector cooperation and creating new business opportunities and sustainable models for regional companies and other actors. The project supports Central Ostrobothnia’s carbon neutrality goal by establishing a partnership model and creating the Central Ostrobothnia Sustainability Network, which will help businesses, municipalities, and other actors develop responsible, low-carbon, and sustainable practices. Actions include promoting the adoption of renewable and clean energy sources as well as material efficiency. The target groups will receive accessible information and tools to improve sustainability efforts, and sustainability expertise will be piloted in the region’s development companies. The dissemination of knowledge and tools will be supported by workshops focusing on sustainability communication, and companies will develop sustainability models, such as annual plans. Additionally, the project aims to shift from a linear economy to a circular economy by encouraging actors to commit to Green Deal agreements and developing eco-industrial and circular economy parks. Cross-sector cooperation will be supported, and new sustainable business models will be created. Regular network meetings, workshops, and events will be organized during the project. As a result, a regional sustainability partnership network will be established, with the capacity to continue after the project ends. Most participating actors will have set climate goals and committed to concrete actions to achieve them, with some also setting energy-saving or material efficiency targets. Furthermore, new emission red
