Tesco, along with Target and CVS Health, has joined the ranks of global businesses requesting more information about their supply chains through environmental non-profit CDP.
It suggests the recent swell in leadership shown by the retail sector is part of a wider pattern of action from businesses, governments and councils around the world, which are increasingly using their purchasing power to tackle climate change.
A total of 115 organisations representing a combined annual spend of more than US$3.3 trillion (£2.5tn) are now requesting data from around 11,500 suppliers.
This is more than 15% increase from last year, when 99 organisations requested data.
Sonya Bhonsle, Head of Supply Chain at CDP, said: “With emissions in the supply chain on average around four times greater than those from a company’s direct operations and rising to up to seven times greater for retailers and consumer-facing companies, large multinational corporations cannot comprehensively address their environmental impact without looking to their supply chains.”
