Our Goals Towards a Zero Carbon Future

We’re committed to achieving net zero carbon emissions across our entire value chain by 2040.
We believe this starts with changing the way we live and work. So, we’re helping the UK to transition to net zero faster by using our products and services to empower our customers to avoid 20 million tonnes of carbon entering Earth’s atmosphere.

Plus, we provide our customers with greener choices to help them live more lower-carbon lives, and support businesses to turn ambition into action.
As a company, we plan to transition to electric vehicles and partner with industry experts like the Carbon Trust to implement the latest best practices. And as a brand, we want to use our TV platform, advertising, venues and partnerships to champion greener living.
