Tesco has reaffirmed its commitment to ethical sourcing after being accused by Greenpeace of selling beef from illegally deforested land in Brazil.

In a report issued this morning, Greenpeace claimed to have found Tesco selling beef from a supplier using farms linked with illegal deforestation in the Amazon.

Tesco said it had started to cut back its supplies from the supplier a year ago and had since ceased sourcing any canned beef products from the company.

“We are committed to tackling deforestation, including working with other consumer goods companies (through the Consumer Goods Forum) to help end deforestation by 202,” the supermarket said.

Ethics and sustainability remained an important part of its dialogue with suppliers, it added.
