On April 15, the Economics of Ecosystems and Biodiversity (TEEB) for Business Coalition released its report Natural Capital at Risk: The Top 100 Externalities of Business which analyzed the environmental costs of doing business. Prepared by Trucost, the report found that the environmental impact of business, such as health costs related to air pollution and loss of natural resources, account for $4.7 trillion in the global economy per year. The Coalition, which includes the World Business Council for Sustainable Development and the World Wildlife Fund (WWF), recommended that companies mitigate exposure to risks in order to support their supply chain and improve investment.
