Abstract

Recent rapid and unexpected cost reductions in decarbonization technologies have accelerated the cost-effective decarbonization of the US economy, with greenhouse gas (GHG) emissions falling by 20% from 2005 to 2020. The literature on US economy-wide decarbonization focuses on maximizing long-term GHG emissions reduction strategies that rely mostly on renewable energy expansion, electrification, and efficiency improvements to achieve net-zero GHG emissions by 2050. While these studies provide a valuable foundation, further research is needed to properly support decarbonization policy development and implementation. In this review, we identify key decarbonization analysis gaps and opportunities, including issues related to cross-sectoral linkages, spatial and temporal granularity, consumer behavior, emerging technologies, equity and environmental justice, and political economy. We conclude by discussing the implications of these analysis gaps for US decarbonization pathways and how they relate to challenges facing major global emitters.

美国能源系统去碳化

最近，去碳化技术的成本出乎意料地迅速降低，加速了美国经济具有成本效益的去碳化进程，从 2005 年到 2020 年，温室气体（GHG）排放量下降了 20%。有关美国经济范围内去碳化的文献主要集中在最大限度地减少温室气体排放的长期战略上，这些战略主要依赖于可再生能源的扩张、电气化和效率的提高，以便在 2050 年之前实现温室气体净零排放。虽然这些研究提供了宝贵的基础，但仍需进一步研究，以适当支持去碳化政策的制定和实施。在本综述中，我们确定了去碳化分析的主要差距和机遇，包括与跨部门联系、空间和时间粒度、消费者行为、新兴技术、公平和环境正义以及政治经济学有关的问题。最后，我们将讨论这些分析差距对美国脱碳途径的影响，以及它们与全球主要排放国所面临挑战的关系。

期刊介绍： The Annual Review of Environment and Resources, established in 1976, offers authoritative reviews on key environmental science and engineering topics. It covers various subjects, including ecology, conservation science, water and energy resources, atmosphere, oceans, climate change, agriculture, living resources, and the human dimensions of resource use and global change. The journal's recent transition from gated to open access through Annual Reviews' Subscribe to Open program, with all articles published under a CC BY license, enhances the dissemination of knowledge in the field.
