The Imps have earned a top three finish in Planet League after carrying out a series of environmentally friendly activities.
After five weeks of staff and supporters making more environmentally friendly choices and scoring goals from activities such as walking to a shop, litter picking and eating plant-based meals, City finished third in the competition.
Vicki Chapman, Lincoln City Foundation’s director of finance, said: “This is a huge achievement, particularly given that second place was taken by Manchester United, with first place going to Northampton Town.”
City’s Planet League players completed a total of 4,870 activities which scored 9,938 goals, saving 25,318 kg of CO2 - which is the equivalent of planting 1,443 trees.
Chapman added: “Taking part in Planet League is both fun and addictive, with a wide-range of activities that the whole family can get involved in.
“My son enjoyed the craft activities aimed at children, finding bugs and hugging trees. It’s a great way of teaching children how they can reduce their carbon footprint and be more eco-friendly in a fun way.
"This helps to embed lifelong changes such as remembering to turn off lights and walking or cycling short distances instead of driving."
