US President Joe Biden presented a national target for greenhouse gas emissions ahead of 2030.
This message has sent renewable power equities soaring, with Danish wind majors Vestas and Ørsted both benefiting from the outlook to heightened political emphasis on green energy.
Vestas stock is up 9.5 percent to DKK 1,319 (EUR 177.4), while the power company's value has increased by 6.7 percent to DKK 981.4.
The two companies' respective equity valuations have thereby jumped by DKK 23bn to DKK 266bn and DKK 26bn to DKK 412.5bn.
Stock analyst and close wind sector tracker Jacob Pedersen from Denmark's Sydbank says Biden's declaration could be worth a lot of money.
He points out that the announcement comes in extension of the EU Parliament reaching an agreement Wednesday to cut the union's CO2 emissions by 55 percent up to 2030.
"These two ambitious political objectives are extremely important signals for the environmental agenda that is currently gaining traction around the world. Achieving these goals is a long way off, and not all targets have been approved yet, but the direction is clear," Pedersen writes in a comment and continues:
"This trajectory is worth gold for Vestas, which holds an enviable position as the world's largest wind turbine manufacturer. Vestas thereby supplies solutions that are central for advancing the sustainability agenda and fulfilling the ambitious goals set by politicians."
Biden's pledge is non-binding, however. The US' prior reduction target within the Paris Climate Accord was a 26-28 percent before 2025 relative to 2005 emissions.
