Decarbonisation is central for achieving the goals of the Paris Climate Agreement, in which 196 countries have committed to significantly reduce their greenhouse gas emissions in order to limit global warming. This includes the expansion of renewable energies for electricity generation and the decarbonisation of traffic and transport as well as entire industries. Significant emission reductions in agriculture are critically important. To accelerate the transition to a world with net zero greenhouse gas emissions, the G7 Academies call for building a carbon-neutral and resilient energy system, strengthening international cooperation towards a just energy transition worldwide by introducing a renewable energy trading system and a global CO2 pricing mechanism, strengthening climate literacy and citizen involvement, and promoting technological and social innovation towards climate neutrality.
