Pompey fans can help the environment and be in with a chance of winning some fantastic prizes, as the club compete in the Green Football Cup.
Starting today and running until Wednesday, February 7, you can score points for the Blues by making pledges.
It could be ditching the car to walk or cycle, or perhaps swapping meat for vegetarian or vegan meals.
Each pledge you make will earn points for Pompey to help power the club up the leaderboard.
Simply click here to get involved and you can also read a special veggie cookbook, which includes a recipe from our very own Tom Lowery for a delicious sweet potato burger.
The campaign is all part of the build-up to the Green Football Weekend from February 2-5, when clubs will be taking part in greener games to reduce carbon pollution.
The football community have the power to drive change and help our planet, so get involved as we look to turn the Blues green!
