Canada sold C$4 billion ($3 billion) of debt Tuesday, its first issue under an amended framework for green bonds that allows the country to raise funds to support nuclear power.
The 10-year bonds have a 3.5% coupon and yield half a basis point less than Canadian government debt due in December 2033.
The new framework makes Canada the first sovereign to venture into nuclear power finance through its green bond sales, the government said in a statement. European Union lawmakers have voted to give certain nuclear projects a sustainable label, a decision that left its parliament deeply divided amid concerns about waste disposal, the potential for weapons proliferation and the risk of accidental radiation.
