Airbnb’s ($ABNB@US) fundraising arm plans to provide temporary housing to an additional 20,000 Afghan refugees, bringing the total to 40,000. Last month, the charitable arm of the short-term lodging service pledged to accommodate 20,000 refugees. A new blog post last week shared Airbnb will now have the capacity to go above and beyond that initial commitment. The refugee stays will be funded by contributions to Airbnb.org, CEO Brian Chesky, and donors to the Airbnb.org Refugee Fund. The company has not specified how much it plans to spend on the commitment or how long refugees will be housed.
