Firms in the UK are failing to engage with their supply chains with regards to climate change and emissions. 

Research by the Carbon Disclosure Project (CDP) and PwC has discovered 48 per cent of companies are not focussing on this issue - the majority of emissions from value chains are not currently measured.

While nearly three-quarters report direct risks, when it comes to indirect risks this figure drops to under a third. 

The research suggests organisations are not sufficiently assessing the whole value chain.

Speaking after the latest Intergovernmental Panel on Climate Change report confirmed that global warming is man-made, chief executive at CDP Paul Simpson said: "UK companies must better integrate climate change management into their business strategy."

Jonathan Grant, director at PwC, added the debate about the science should now be over as far as firms are concerned and so attention should turn to identifying business risks and finding solutions.
