We are facing a tragedy of the commons, and individual action does not solve that. This holds true for overfishing, pollution, greenhouse gas emissions, you name it. The change we need is pigovian taxes, which factor negative externalities into the price of the activity causing it, instead of letting them be amortised by society. Consumer-shaming is not how we solve a tragedy of the commons. If half the world stops burning fossil fuels tomorrow, the other half will enjoy cheaper oil and double their emissions the next day. Tax pollutants.
