We have a HSE Management Committee, which was created by our executive officers to ensure that HSE issues are addressed throughout the company. The committee is composed of executive managers of our different business segments and of directors of our controlled companies. The work of the HSE Management Committee is supported by three permanent subcommittees, two temporary commissions and one temporary work group, each one responsible for a specific HSE issue, such as licensing and environmental compensation and risk assessment.
We have also created an Environmental Committee, which is composed of three members of our Board of Directors, including our Chairman and our Chief Executive Officer. The committee is responsible for, among other things: (1) overseeing and managing environmental and work safety issues affecting us; (2) establishing measurable environmental targets and ensuring compliance; and (3) recommending changes in environmental, health and safety policy, if necessary, to our board of directors. The Environmental Committee charter is still subject to approval by our Board of Directors.
