We’ve announced that we will reduce our carbon emissions by 87% by 2030, helping to limit global warming to 1.5°C by the end of the century.

As part of the transition to a low carbon business model, we had previously set ourselves a target in 2008 of an 80% reduction of our carbon emissions by 2020.

After reaching this target four years ahead of schedule, we’ve set a new 2030 target, approved by the Science-Based Targets Initiative, which is aligned with the most ambitious aim of the COP21 Paris Agreement. This aim seeks to limit global warming to well below 2°C above pre-industrial levels and pursue efforts to limit it even further to 1.5°C by the end of the century.

To meet this ambitious goal, we will be targeting innovative ways to further reduce our dependency on fossil fuels, for example through the adoption of low carbon vehicles in its fleet and reducing the carbon intensity of buildings.

Announcing the target, BT Chief Sustainability Officer Niall Dunne said: “The role that technology can play in creating a more resource efficient world is both profound and exciting. The benefits of leading climate action extend to our customers, suppliers and people. Our commitment to this 1.5°C target will help create partnerships and coalitions that continue the unstoppable momentum enabled by the Paris agreement.”

Tom Delay, Chief Executive, the Carbon Trust commented: “Over the past two decades BT has made impressive progress in reducing carbon emissions. To continue this journey, our recent work together has mapped out the steps the business will need to take over the coming decades to become a truly low carbon business. The ambition contained within the Paris Agreement gives us hope that we might avoid the most dangerous impacts of climate change. If we are going to deliver on this ambition then this is exactly the sort of leadership we need to see.”

As part of our wider energy programme, we’ve already made significant strides in reducing our end-to-end carbon footprint which has helped to deliver a total of £221m of energy savings since 2009/10. We are also well on our way to achieving our commitment to purchase 100% renewable electricity for our operations by 2020, where markets allow, sourcing 82% renewably last year.

In addition, we also promote energy efficiency by providing products and services that enable our customers to reduce emissions. As part of our 2020 ambitions, we aim to help our customers cut their carbon emissions by at least three times our own end-to-end carbon impact. So far we’ve reached 1.8 times, enabling customers to avoid 10 million tonnes of carbon in 2016/17, up 32% on the previous year. These carbon-abating products and services represented £5.3bn, or 22%, of our total revenue last year.

Our commitment to reducing our carbon intensity will help the UK Government meet its carbon reduction targets. International climate negotiations will continue at COP23 in Bonn this November.
