EcoCounts is a North London charity aiming to revolutionise the way we account for CO2 emissions. Our methodology involves participants meticulously recording their personal carbon footprint, derived from their daily purchases and activities. Our objective is to implement carbon budgets for participants, eventually progressing towards the implementation of personal carbon trading. This unique system allows individuals within our group to trade carbon emissions, empowering everyone to manage their emissions effectively while collectively reducing the overall carbon footprint of the community. To achieve this we need a high level of accuracy in our information not obtainable from the use of online carbon calculators or broad estimates.
