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 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.
