Office space sharing company WeWork says it is no longer serving red or white meat at company events.

In an email to employees Thursday, co-founder and Chief Creative Officer Miguel McKelvey said the company won't serve pork, poultry or red meat, and it won't allow employees to expense meals that include those meats to the company. Fish will stay on the menu.

McKelvey said the change means WeWork will use less water and produce less carbon dioxide as well as saving the lives of animals.

The company said employees are welcome to bring whatever food they want to work.

The policy is effective immediately and also applies to the company's Summer Camp gathering in the United Kingdom in August. McKelvey wrote that WeWork could save 10,000 animals by eliminating meat at the upcoming Summer Camp event. It has 6,000 employees and some 5,000 attended the event in 2017.

WeWork has locations in 22 countries and a total of 75 cities, including Toronto, Montreal and Vancouver. The company declined to say how much water it expects to save in 2018 or 2019 from the new policy, or how much carbon dioxide it could save in the next two years. The company gave longer term projections based on its estimates for future growth over five years.

WeWork's meat policy may be unique, but the company is joining a group of companies that have recently looked for ways to reduce their impact on the environment. Coffee chain Starbucks, airlines including American and Alaska, and the Hilton and Hyatt hotel chains have all recently announced that they will stop using plastic straws so they produce less plastic waste. Some cities have banned the straws as well.
