Carbon Footprint

Solar panels

We have a longstanding commitment to tackling climate change. We were the first FTSE100 company to set ambitious science-based targets to become a zero-carbon business by 2050, in line with the 1.5-degree trajectory recommended by the Paris Climate Agreement. In the UK, we are aiming to reach net zero earlier, by 2035.

In December 2020 we re-baselined our carbon figures to reflect the sales of our businesses in Thailand, Malaysia and Poland, as announced in 2020. During this process we have also incorporated data improvements since the latest assurance statement. All figures on this page are up to date. More information on our base year recalculation policy can be found here.

Some highlights from our climate change work include:

  • Reducing our absolute carbon emissions by 50% since 2015/16 using the market-based method for calculating our electricity impacts, and 32% using the location-based method.

  • 100% of electricity purchased for the UK, Ireland, Hungary and Slovakia is renewable, supported by renewable energy certificates.

In 2019/20 we have made good progress on our targets:

Target

Progress to date

Reduce absolute carbon emissions from our operations from 2015/16 levels: 35% by 2020, 60% by 2025 and 100% by 2050.

50% (using the market-based method)

Source 65% of our electricity from renewable sources by 2020 and 100% by 2030.

97% supported by renewable energy certificates

We measure and report our carbon emissions following the Greenhouse Gas Protocol. For more information about how we calculate our carbon footprint, including reporting standards, a more detailed definition of Scope 1, 2 and 3 emissions, and the current emission factors visit our carbon footprint methodology page.

To demonstrate how we will meet our commitment on sourcing 100% of our electricity from renewable sources, we have published our Group renewable electricity transition road-map here.
