Evergen are an energy and environment company. Since 2010 we have been installing Solar generation, electricity storage and Energy Management Systems on homes, commercial properties and public sector buildings. As well as saving our customers £thousands on their annual energy bills, all of these activities have a direct impact on cutting CO2 emissions.

In early 2016 we started looking into ways of tackling urban air pollution. Air quality is huge problem and barely a day goes by without a story in the national or city media focusing on the deteriorating quality of our air and its impacts on human health. We wanted to find technology solutions to tackle this problem. After almost two years of researching and trials of a number of technologies, we have licensed the most advanced technology in this space – CityTree – the world’s first Biotech filter for cleaning urban air pollution.
