I'm wondering what measures, given sufficient resources, could have a meaningful impact in quickly reducing global emissions. I'm especially interested in what would require the involvement of a large group of people (millions) and/or the use of large quantities of money ($ billions).Some examples:- Assist governments in accelerating the ecological transition in their countries, giving access to additional resources when needed- Institute funds to reward individuals who contribute to the environment, for example by installing renewable energy systems or consuming green energyIt would be great to learn more about the root causes of the slow reduction in emissions, the main challenges and why they haven't been solved yet.
