 Europe is setting the goal to combat climate change through collective effort. Every day, more technologies are developed to help us transition to a decarbonised Europe. To ensure a bright future for all, we want to understand the possible path for making decisions. However, information on the various developments and possibilities is scattered. Consequences and trade-offs are unclear and are many divergent interests. What if we could combine this information into a comprehensible tool, a single webpage? Then we could make informed decisions about the future of Europe. EU Calc provides a user-friendly modelling solution, accessible free of charge. It calculates greenhouse gas trajectories, social implications, cost, limitations and future energy demand. On the ambition level of your choice. An online course on climate change mitigation is offered to future decision-makers. With the help of EU Calc, we can make informed decisions about our path to a bright future.
