Second, governments could build carbon-neutral cities or other large-scale demonstration projects, while grass-roots efforts could help existing towns and cities move toward being carbon-neutral. These actions would help spread information and build consumer interest in fossil-fuel-free technologies, until they become the first choice for new projects.
Third, divestment from fossil fuel assets and withdrawal of insurance support for fossil fuel projects would help burst the ‘carbon bubble,’ making it unprofitable to develop remaining fossil fuel reserves.
Next, activists and opinion leaders could emphasize the moral implications of fossil fuels – that is, the idea that burning fossil fuels in ways incompatible with the Paris climate targets is immoral. This has the potential to shift societal norms and, consequently, widespread patterns of behavior.
Fifth, a massive climate literacy campaign to strengthen education about the climate in schools and universities, resulting in a generation of workers and leaders who are focused on stopping climate change.
And finally, better education of the general public by disseminating information about the carbon impacts of consumer and lifestyle choices – basically the climate equivalent of nutrition labeling."
