This paper proposes an assessment of long-term climate strategies for oil- and gas-producing countries—in particular, the Gulf Cooperation Council (GCC) member states—as regards the Paris Agreement goal of limiting the increase of surface air temperature to 2°C by the end of the twenty-first century. The study evaluates the possible role of carbon dioxide removal (CDR) technologies under an international emissions trading market as a way to mitigate welfare losses. To model the strategic context, one assumes that a global cumulative emissions budget will have been allocated among different coalitions of countries—the GCC being one of them—and the existence of an international emissions trading market. A meta-game model is proposed in which deployment of CDR technologies as well as supply of emission rights are strategic variables and the payoffs are obtained from simulations of a general equilibrium model. The results of the simulations indicate that oil and gas producing countries and especially the GCC countries face a significant welfare loss risk, due to “unburnable oil” if a worldwide climate regime as recommended by the Paris Agreement is put in place. The development of CDR technologies, in particular direct air capture (DAC) alleviates somewhat this risk and offers these countries a new opportunity for exploiting their gas reserves and the carbon storage capacity offered by depleted oil and gas reservoirs.

海湾国家长期气候战略中CO 2直接还原技术发展的经济评估

本文提出了针对石油和天然气生产国(尤其是海湾合作委员会(GCC)成员国)的长期气候战略的评估,涉及《巴黎协定》的目标,即将地面空气温度的升高限制在2°以内。 C在二十一世纪末。这项研究评估了在国际排放交易市场下二氧化碳去除(CDR)技术作为减轻福利损失的一种可能的作用。为了模拟战略背景,我们假设将在不同国家联盟(GCC就是其中一个国家)之间分配全球累积排放预算,并建立一个国际排放交易市场。提出了一种元博弈模型,其中,CDR技术的部署以及排放权的提供是战略变量,其收益是通过模拟一般均衡模型获得的。模拟结果表明,如果按照《巴黎协定》的建议建立全球气候制度,油气生产国,特别是海湾合作委员会国家将面临重大的福利损失风险,这是由于“不可燃的石油”造成的。CDR技术的发展,特别是直接空气捕获(DAC)的使用,在某种程度上减轻了这种风险,并为这些国家提供了开发其天然气储量和枯竭的油气藏提供的碳储存能力的新机会。模拟结果表明,如果按照《巴黎协定》的建议建立全球气候制度,油气生产国,特别是海湾合作委员会国家将面临重大的福利损失风险,这是由于“不可燃的石油”造成的。CDR技术的发展,特别是直接空气捕获(DAC)的使用,在某种程度上减轻了这种风险,并为这些国家提供了开发其天然气储量和枯竭的油气藏提供的碳储存能力的新机会。模拟结果表明,如果按照《巴黎协定》的建议建立全球气候制度,油气生产国,特别是海湾合作委员会国家将面临重大的福利损失风险,这是由于“不可燃的石油”造成的。CDR技术的发展,特别是直接空气捕获(DAC)的使用,在某种程度上减轻了这种风险,并为这些国家提供了开发其天然气储量和枯竭的油气藏提供的碳储存能力的新机会。
