One eutrophication goal in terms of an Environmental Index would be beneficial instead of two separate ones in terms of nitrogen and phosphorus reduction.

This is one of the deductions from Erik Geijer's thesis (see headline). He has been looking closer at conflicts between coherent goals in Swedish environmental policies and projects.

Conserve forest and supply forest fuel

Geijers result imply that if we were to protect another four percent of our forest land it would lead to a decrease of forest fuel which in its turn could lead to an increase in emission from non-renewable sources with about 0.9 percent.

The thesis also claims that "large-scale implementation of stump harvests would result in a 3% increase in the use of renewable energy sources" "but a 5% reduction in abundance of saproxylic beetles". There is also discussion regarding the conflict between clean energy and protection of the white-tailed eagle population.
