The report is due to be discussed by the council in May

Research from north London's Camden Council's sustainability taskforce, said the move would help the authority cut the size of its carbon footprint.

The recommendation would affect schools, care homes and council premises if given the go-ahead.

Camden Council said the report was still at draft stage and would be discussed by executive members in May.

Report author councillor Alexis Rowell said it was important as much food was sourced from local suppliers as possible.

Livestock industry

"We're very concerned that the livestock industry produces 18% of the world's carbon emissions according to the UN, therefore for climate change and health reasons we need to be cutting down on meat and dairy," he said.

"But we're not saying that everyone should be vegetarian."

He added: You can get all the protein you need from a varied diet that includes less meat and dairy and more seeds and nuts.

"Even choosing different types of meat, like rabbit rather than beef - which is the most intensively reared meat, uses the most fossil fuels and is worse for your health - could do a huge deal of good."

Other recommendations in the report include making better use of green space on council estates, allowing people to develop gardens on roofs and banning bottled water from council canteens.
