WeWork is trying a new tactic in the push toward corporate sustainability by saying it was committed to being “a meat-free organization.” The global network of shared office spaces said in an email to employees last week that “moving forward, we will not serve or pay for meat at WeWork events and want to clarify that this includes poultry and pork, as well as red meat.” The company’s co-founder and chief culture officer, Miguel McKelvey, said the new policy was one way it could do more to become environmentally conscious. After the policy garnered headlines over the weekend, sustainability experts said it is rare — even as employers become more focused on showcasing their environmental friendliness — to see companies make a direct connection between meat and climate emissions. Such environmentally tied policies on employee behavior — such as tracking printing habits or financial rewards for public transit use — could be a sign of things to come, as employers seek to prove their environmental mettle with millennial workers attracted by such progressive policies.
