We only have 8.5 years left. People need to change their behaviour and become more educated. This then puts pressure on, and allows politicians to put in place the policy needed to reduce CO2 substantially to avoid climate catastrophe. The way we believe this will be achieved, is via an app used extensively by all types of people that uses positive peer-pressure as the driving force to record, incentivise and drive individual and group actions to reduce their CO2 footprint - a virtuous circle. We have just finished a crowdfunding campaign to build the app, and so are expanding!
