Substantial abatements of CO₂ emissions from fossil fuel combustions are critical to shifting the current trend of fast global warming. In this Perspective, chemical fixation of CO₂ (CFC) is evaluated as a progressive abating strategy by a proposed “golden triangle” principle. We derive several simple equations to describe partially the relationships between energy and CO₂ arising from fossil fuel combustions in the power sector upon energy/mass-balance analyses of related electrochemical reductions of CO₂ (ERCs) as a route to CFC. Mitigation coefficients are obtained as figures of merit to quantify the intrinsic abatement capabilities of various reduction products, identifying privileged ERCs that may allow fossil fuel power, the current and expected dominant source of electricity at least before 2040, to drive the ERCs for emission abatements. The challenges for large-scale deployments of the ERCs as a substantial emission-abating strategy are discussed upon sensitivity analysis of mitigation efficiency for selected privileged ERCs.

大量减少化石燃料燃烧产生的CO ₂排放对于改变当前快速的全球变暖趋势至关重要。在此观点中，通过提出的“黄金三角”原理，将化学固定法CO ₂（CFC）评估为渐进减缓策略。我们通过对相关的CO ₂电化学还原反应进行能量/质量平衡分析，得出了几个简单的方程来部分描述电力部门中化石燃料燃烧产生的能量与CO ₂之间的关系。（ERC）作为通往CFC的途径。获得缓解系数作为品质因数，以量化各种减排产品的内在减排能力，确定可让化石燃料发电（至少在2040年前成为当前和预期的主要电力来源）驱使ERC减排的特权ERC。通过对选定特权ERC的缓解效率进行敏感性分析，讨论了将ERC大规模部署为一项重要的减排战略所面临的挑战。
