Heating your house produces CO2 (carbon dioxide) gases, this is unavoidable. But what you can do is offset these climate-impacting emissions by purchasing power that offers carbon-offsetting measures. This means that although CO2 is being produced in one part of the world, the offset contributions are paying for a reduction in these same greenhouse gas emissions in developing countries. Initiatives include solar housing in India, biogas plants in Nepal, wind farms in Madagascar and organic composting projects in Bali. We use reputable carbon-offset registries: myclimate (Switzerland) and TZ1 (USA).
