No meat, no dairy and three outfits a year: Welcome to Sadiq Khan’s plan for London

C40 is a global collective of city mayors chaired by Sadiq Khan .

It advocates extreme measures to halve greenhouse gas emissions by 2030 and limit global temperature rises to 1.5C.

Its more radical suggestions involved the abolition of private vehicles and the prohibition of meat and dairy consumption.

Critics say the report is emblematic of C40 as an unelected, self-appointed body.

Anna Beech , managing director for governance and executive engagement, helped draw up London ’s first climate change action plan under Boris Johnson .

C40 employs 279 people outside of this management team, all of whom are subject to a stringent eco-friendly office regime.

Internal staff documents ban the use of paper, even for note-taking and to-do lists.

Flights and taxis can only be justified in exceptional circumstances’ and additional time off in lieu is given to staff forced to travel by train instead.
