Toshiba: In Response to Climate Change - Environment

GovernanceStrategyRisk ManagementMetrics and TargetsWe have a system in place by which the board of directors appropriately monitors our efforts to address climate change and other important environmental issues. In particular, the Corporate Environmental Officer brings up important issues related to management risks and opportunities to the President at Management Committee meetings or executive officers' meetings. These issues are also reported about twice a year to all directors, including outside directors, at board of directors meetings. What is discussed and decided upon at board of directors meetings is reflected in our groupmanagement strategy. Prior to board of directors meetings, the policies, strategies, and measures related to the environment, including climate change, are discussed at the Corporate Environmental Management Committee, which is chaired by the Corporate Environmental Officer. This semiannual meeting is attended by the environmental promotion managers of key group companies, corporate staff division manag...Get price
