CDP, a charity which says it works with institutional investors with assets of $96 trillion (£77 trillion), said 70% of 1,500 large companies failed to provide data on their impact on forests in response to its queries last year.”The silence is deafening when it comes to the corporate response to deforestation,” said Morgan Gillespy, global director of forests at CDP, formerly known as the Carbon Disclosure Project.

“Consumers increasingly want to know that their shopping basket isn’t driving the destruction of the Amazon, extinction of the orangutans and the climate crisis,” she said in a statement.CDP has emerged as a leading voice in a broader push by investors seeking disclosure from companies on the risks they may face as global warming exposes them to extreme weather, supply chain collapse and a host of other forms of disruption.Since 2014, the charity has also asked companies to report on their impact on forests in terms of timber, palm oil, cattle and soy farming, as part of a growing recognition of the role forests play in preserving species and stabilising the climate.Of the 306 companies that did report data, 24% showed no or limited action to reduce deforestation, despite brand damage from being associated with the loss of forests the most frequently cited risk, CDP said.CDP named French beauty brand L’Oreal and German consumer goods manufacturer Beiersdorf AG as the leaders in seeking out sustainable sources of palm oil.But it warned the vast majority of companies were not moving fast enough on efforts to preserve forests.Some companies that CDP said had failed to respond to its questions on forests said they were committed to greater sustainability.British clothing chain Next, for example, said it had completed the CDP climate questionnaire for many years, and had laid out a commitment to source 100% of its timber from responsible or certified sources by 2025.
