Thank you, Mr. Chairman.
Generally speaking, the department has adopted Ms. Brundtland's definition. You no doubt remember the Brundtland Commission which was created several years ago and which was a major United Nations commission. The commission proposed a definition whereby, when resources such as energy are used, it is not necessary to renew this type of energy in particular, but to ensure that, through science, technology or research, a substitute resource is available in the future. That is really the definition we use.
Several private sector organizations and organizations within civil society believe that we should always be able to replace what is being used in the same subsector. For our part, we believe that the definition of the Brundtland Commission has a more reasonable application, since it refers to the constant renewal of a resource, but not necessarily of the same resource.
