COP26 stands for Conference of the Parties and is a summit of world leaders who come together to discuss how to combat climate change. As the name suggests, this is the 26th in the series. People often remember COP21, where global leaders formed the Paris Agreement. The ambition of COP26 is to make fresh commitments to drastically cut emissions and keep temperature rises to 1.5 degrees above pre-industrial times.

In this week’s Walking the Walk episode, presenter Dominic Laurie talks to Head of Sustainability Will Ennett about the work that TalkTalk is doing to reduce carbon emissions. From embracing circular principles by designing products to maximise refurbishment to engaging with colleagues, customers and the supply chain – Will discusses how collaboration and innovation are at the heart of solving difficult environmental problems.
