One of the things that is potentially useful in getting people to pay attention at the director general level and up is that section 12 of the current act says:
Performance-based contracts with the Government of Canada shall include provisions for meeting the applicable targets referred to in the Federal Sustainable Development Strategy and the Departmental Sustainable Development Strategies.
In English what that means is that civil servants above a certain rank will have their annual performances reviewed. In part one of the considerations will be how much they adhere to the targets in the Federal Sustainable Development Act.
