O2 vs CO2

At O2, we’re on a mission to reduce CO2

We’re committed to the environment

We're reducing CO2 by buying 100% renewable electricity to power our network.
Every O2 office, store, and phone mast where we directly control the bill is powered by renewable electricity.

We’re the only mobile network operator to commit to net zero carbon by 2025.
Out of the four mobile network operators in the UK we’re the only one to publicly commit to being net zero carbon by 2025, in our own operation.

We're the only network to receive the highest certification for carbon reduction in our supply chain
In fact we’re one of only 8 companies worldwide to hold the Carbon Trust level three standard for supply chain management. We were first certified in 2016 and we were recertified again for two years for emissions management in 2019.
