More people thinking about how to reduce #CO2 emissions can only have a positive effect. In all contexts (e.g., individuals, organisations), what needs to happen is that society makes plans, & follows through on them, to provide lower CO2 activities. We generally know what those lower CO2 activities are. For example, #transport is the highest CO2-emitting activity sector, therefore, replacing private vehicles with EV public transport will decrease CO2 emissions
