Europe mastered the corona crisis, but a bigger one is already on the list: the climate crisis. The EU set ambitious goals for their climate change programme, but still the question remains how to reach them. Hopes in ClimateTech are thus huge and AI is to expected to play a key role. However, AI is also a driver to CO2 emissions: it consumes a lot of energy and it is also used e.g. to detect new oil deposits. How helpful is AI really and is Europe prepared to lead in and with AI the climate movement? Finally, what political and legal changes, technical infrastructure, economic conditions and so on are required to strengthen the climate tech community?
