The Green Star league competition recognises Sefton schools' work on a variety of environmental issues, looking at the school’s Carbon emissions and the energy rating of the school buildings.

Each school, upon registration, is allocated a baseline number of Green Stars with bonus stars being awarded during the year for any additional outstanding work carried out that schools tell us about. There are two leagues, a primary and a secondary category. Each year the league winners and the most improved schools are invited to the Eco-Champions award ceremony to receive their trophies and certificates.
