Homes for bats, on-site allotments and recycled kits are just some of the ways Premier League clubs are continuing to improve their ‘green’ credentials.
Tottenham and Liverpool have come joint-top of the 2021 Green League – a table measuring the sustainability of all 20 top-flight sides.
Tottenham Hotspur players now travel to matches on coaches powered by biofuel, reducing squad coach travel emissions by over 80%. While other clubs such as Liverpool have committed to decarbonising fuel through the use of sustainable aviation fuel in the future, which would also reduce emissions by 80%.
What is the sustainability table?
BBC Sport has worked with the United Nations-backed Sport Positive Summit since 2019 to research the sustainability of all 20 Premier League clubs, with the rankings updated each year.
Teams were asked to provide evidence of efforts in 11 categories. Two points are available for each category as well as two bonus points, making a maximum of 24 points.
Points were awarded for:
- Policy and commitment
- Clean energy
- Energy efficiency
- Sustainable transport
- Single-use plastic reduction or removal
- Waste management
- Water efficiency
- Plant-based or low-carbon food
- Communications and engagement
A bonus point was awarded if the club is certified to an internationally recognised sustainability management system or if a club track and report on percentage of fans taking various modes of transportation to games.
