On the eve of the 2012 Atlantic hurricane season, Calvert Investments, Ceres and Oxfam America released a new guide today for companies to improve their analysis and management of the risks that climate change poses to their operations and supply chains. The groups also urged better transparency and disclosure from companies on the threats they face because of increasingly frequent and severe climate impacts...The newly released guide, “Physical Risks from Climate Change: A guide for companies and investors on disclosure and management of climate impacts,” focuses on companies in the agriculture, food and beverage, apparel, electric power, insurance, mining, oil and gas, and tourism sectors, all of which are highly vulnerable to climate impacts.
