The 24 milestone targets indicate steps along the way to the environmental quality objectives and the generational goal.
The milestone targets are intended to identify a desired social change and specify steps towards achieving the generational goal and one or more of the environmental quality objectives.
However, they are not to specify a state of the environment, since this is established in the environmental quality objectives and the associated specifications.
Milestone targets can also be added to the environmental objectives system on the basis of goals adopted within the European Union or by incorporating international agreements into the system.
The milestone targets are divided into five areas: reduced climate impact, air pollution, dangerous substances, waste, biodiversity.
