The European Commission’s Joint Research Centre are going to help users of a mobile application to track their carbon footprint.
MobGAS allows users to see the implications of the choices they make every day in terms of the three major greenhouse gases: carbon dioxide, methane and nitrous oxide.
Users can calculate individual emissions by entering information about everyday activities, such as cooking, transport, lighting and the use of electronic appliances.
MobGAS generates a diary of daily, weekly and yearly emissions which can be registered on a secure website, allowing users to compare their results with national and global averages.
You can download the software from the MobGAS website
