Purchasing managers at the world’s largest companies used their clout to reduce carbon dioxide emissions in their supply chains by the equivalent of 434 million tonnes of carbon during 2016.

Figures compiled by carbon dioxide disclosure firm CDP drew on data from 89 businesses, including BMW, Johnson & Johnson, Microsoft and Walmart.

Supply chains are responsible for on average of four times a company’s direct emissions.

Twenty-nine companies – including American computer maker Hewlett-Packard, Dutch electronics group Philips and Brazilian chemicals firm Braskem  – were awarded a position on CDP’s first supplier engagement leader board.

Key to Paris Agreement

Dexter Galvin, Head of Supply Chain at CDP, said: “We congratulate the 29 leading companies that are using their buying clout to drive change across their supply chains.

“Companies have a critical role to play in delivering on the Paris Agreement, and as well as setting their own house in order, it is essential they turn their attention to the risks and opportunities outsourced to their supply chain.

“By harnessing their purchasing power, big buyers have the potential to deliver the large-scale, rapid change that is needed and lead the way towards our sustainable future.”
