Sweden's Riksdag is set to vote on June 11 on a government proposal that would loosen protection for some of the country's most valuable coastal areas and make room for nuclear power. If adopted, the change could open parts of northern Bohuslän, Öland, the High Coast and the archipelagos of Östergötland and Småland to projects now blocked by the Environmental Code.

The timing matters because the government wants to clear the way for new nuclear power where it is currently prohibited, and it is doing so in a place where protection has long been treated as a line that should not be crossed. One application already under review concerns new nuclear power at Studsvik outside Nyköping, and another involves plans for four to six SMR reactors in Valdemarsvik municipality, inside areas that currently carry protection.

Karin Lexén, one of the named authors behind the criticism, says the point of the safeguard is that certain areas should not have to defend themselves project by project, process by process, or mandate period by mandate period. That argument cuts to the center of the dispute: the government describes the change as a limited adjustment inside a strong environmental protection system, while critics see a fundamental reversal of long-standing protection for unique natural areas.

The protection for unbroken coasts was introduced after decades of heavy exploitation of Sweden's shoreline, as concern grew in the 1970s and 1980s about the need for long-term management of land and water. Special rules were then created for larger stretches of coast to preserve values tied to nature conservation, cultural heritage, outdoor recreation and tourism. The proposal now on the table would remove the national interest designation for the highly exploited coast in relation to nuclear power, even as the government has also pushed weaker shoreline protection, weaker species protection and greater state authority over so-called national interests.

That wider pattern has sharpened the stakes around Wednesday's vote. Major referral bodies have sharply criticized the plan, but the government has dismissed those objections and says Sweden can expand fossil-free energy without bringing its most valuable coastal environments into use. If the Riksdag approves the proposal, the effects could arrive quickly, with protected land from northern Bohuslän to Valdemarsvik potentially facing a new round of industrial planning almost immediately.
