Growing fossil fuel divestment commitments and the mainstreaming of climate risk into financial analysis are increasingly shaping the cost and availability of capital for parts of the hydrocarbon sector. Yet the architecture of sustainable finance is sufficiently broad to accommodate oil and gas companies that can demonstrate credible, commercially grounded progress toward lower-carbon operations. This paper maps 12 options for hydrocarbon producer engagement with sustainable capital markets to four distinct pathways through which ESG engagement can reduce weighted average cost of capital (WACC): a risk-based channel, a constraint-based channel, an outcome-based channel, and an instrument-based channel.
