Paul McCartney has called upon those involved in the current climate change conference to consider introducing a ‘Meat Free Monday’ initiative.

The Beatles legend has written two letters to figures involved in the Conference of the Parties’ discussions, which are taking place in Doha, Quatar, asking them to take account of livestock production and the impact it can have on climate change.

McCartney, who sent a copy of the letter to Christiana Figueres, Executive Secretary of the United Nations Framework Convention on Climate Change, and Qatar’s Deputy Prime Minister Abdullah bin Hamad Al-Attiyah, wrote: “Although more and more evidence is coming to light showing how the growth of the global meat industry is having alarming environmental consequences, the impact of the livestock sector on global warming does not yet seem to have been acknowledged by the Conference of the Parties (COP).”

It added: “I therefore call upon you to bring this issue to the attention of the conference and encourage the adoption of policy and individual actions, such as a weekly meat-free day… Encouraging initiatives such as Meat Free Monday would make a considerable difference to the future of the planet.”

Paul McCartney is reportedly working on a new album, the follow-up to this year’s collection of covers, Kisses On The Bottom. Producer Ethan Johns recently told NME that he had been in the studio with him, along with Mark Ronson. Adele producer Paul Epworth is also reported to be working on the record.
