Climate investment plans were originally about looking at the total investment need to reach the climate goals in order to create an understanding of the capital needs of the transition. In the process of developing climate investment plans, however, many other schools of thought have been born. Investments made in the future that are not initiated to reduce CO2 emissions can account for a large part of future emissions, e.g. in infrastructure and buildings. How do these investments relate to the climate investment plan? How should we calculate the net climate benefit of an investment? How can climate benefit calculations contribute to better decision-making? The project addresses the need to better integrate climate investment plan aspects in the municipal management, governance and follow-up, as well as the need to design decision-making processes and develop decision-making documents as well as key figures and indicators that make it possible to steer towards adopted climate goals.
