Focus on the Mission Act of 2023

This bill prohibits the U.S. Department of Defense from requiring defense contractors to report greenhouse gas emissions. It specifically bans the Secretary of Defense from mandating any "greenhouse gas inventory" or reports on Scope 1, Scope 2, or Scope 3 emissions from contractors holding federal defense contracts. The law directly affects defense contractors who would otherwise have been required to track and disclose their emissions data. It removes a specific reporting requirement for contractors under Defense Department contracts, without altering other environmental regulations.
