Commitments through financial options: an alternative for delivering climate change obligations

Roland Ismer and Karsten Neuhoff ()

Climate Policy, 2009, vol. 9, issue 1, 9-21

Abstract: Governments willing to commit themselves to maintain carbon prices at or above a certain level face the challenge that their commitments need to be credible both for investors in low-carbon technology and for foreign governments. This article argues that governments can make such commitments by issuing long-term put option contracts on the price of CO 2 allowances. This mechanism gives investors the right, but not the obligation, to sell allowances to the government at the strike price. From the investors' point of view, a government is therefore fully committed to a price floor for allowances in the future. This proposed approach alters the incentives that a government faces when considering noncompliance and serves to prevent non-compliance. The proposal fares well when assessed against criteria to determine its suitability in legitimacy, enforcement, proportionality, lack of interference from other contracting States, and transparency. It also allows for fine-tuning through the number and duration of issued options and the strike price. A robust contract structure is proposed to protect against government interference that might threaten the credibility of commitments.
