The Government of Canada issued a $4 billion ten-year sovereign green bond in February 2024, the second issuance under its green bond programme since it launched in 2022. The bond is the first to be issued under the government's updated framework, which was revised in November 2023 to add nuclear energy expenditures as an eligible category for the allocation of proceeds.

Proceeds from the issuance will be directed towards clean energy, clean transportation, and energy efficiency projects, consistent with the environmental objectives underpinning the programme. The inclusion of nuclear energy in the updated framework marks a notable evolution in how the Canadian government characterises eligible green expenditure, reflecting a growing debate internationally about the role of nuclear power in low-carbon energy transitions.

UPDATED FRAMEWORK AND NUCLEAR ELIGIBILITY

The revision to Canada's sovereign green bond framework, published in November 2023, extended the list of eligible expenditure categories to encompass nuclear energy spending. This addition places Canada alongside a small but growing number of sovereigns and multilateral institutions that have moved to include nuclear within their sustainable finance frameworks, a step that has generated both support and criticism within the responsible investment community.

Proponents of nuclear inclusion argue that the technology produces electricity with minimal greenhouse gas emissions over its lifecycle and that it can provide the reliable baseload generation capacity that variable renewable sources such as wind and solar cannot consistently deliver. Critics contend that the long construction timelines, cost overruns associated with new nuclear projects, and challenges around waste management complicate its classification as unambiguously green. The Canadian government has nonetheless determined that its domestic nuclear expenditure qualifies under the updated framework.

The updated framework retains clean energy and clean transportation as core eligible categories, alongside energy efficiency measures. These areas align with the standards recommended by internationally recognised principles for green bond issuance and with Canada's own federal climate targets, which include commitments to achieve net zero emissions by 2050.

MARKET AND PROGRAMME CONTEXT

Canada's sovereign green bond programme, launched in 2022, is part of a broader effort by the federal government to mobilise institutional investor demand for climate-aligned fixed income assets. Sovereign green bonds from G7 governments attract particularly strong interest from asset managers with environmental, social, and governance mandates, including pension funds and insurers required to demonstrate the sustainability credentials of their portfolios.

A ten-year maturity matches the typical duration preferences of long-term institutional buyers, and a $4 billion issue size is large enough to ensure liquidity in secondary markets, which is a key consideration for investors who may need to trade the bonds before maturity. The Department of Finance manages the issuance through the government's regular debt programme, with the bonds qualifying for Canada's debt management objectives alongside conventional bond sales.

The issuance will be followed by allocation and impact reporting, through which the government discloses how proceeds have been applied to eligible categories and provides metrics on the environmental outcomes achieved. This reporting commitment is standard for sovereign green bond programmes and enables investors to assess whether the proceeds are being deployed in line with the framework's stated objectives.
