“As part of its overall strategy to become a carbon neutral city by 2025, Copenhagen has become the first Scandanavian city to adopt a policy that requires green roofs for all new buildings with roof slopes of less than 30 degrees. Copenhagen presently has 20,000 square meters (over 215,000 square feet) of flat roofs. It is hoped that as much as 5,000 square meters of new development each year will be covered with vegetation.”
