The environment secretary, Hillary Benn, will this week renew calls for consumers to cut back on the amount of red meat in their diets, in a move likely to cause dismay among UK farmers.

Benn will outline his Food 2030 policy document at a food conference this week. Other proposals will include measures to curb food waste, including ending supermarkets’ bogof deals and the use of ‘best before’ dates, as well as moves to encourage the use of public land for allotments.

“Livestock production is a major contributor to greenhouse-gas emissions globally and some groups advocate a diet with less meat as a way for consumers to reduce the environmental footprint of their diet,” a Defra source told the Daily Mail.
