根据年度CERES基准报告,美国电力部门的排放于2021年回报
根据该国100个最大的电力生产国的空气排放的新基准分析,全世界的经济在与冠状病毒大流行有关的关闭后重新开放,全世界的经济重新开放,美国电力部门的二氧化碳排放量增长了7%。在2020年,该行业的二氧化碳排放量下降了创纪录的10%,比报告的18版在排放量最大的一年减少。
2021年的增加破坏了所有电力部门空气排放的稳定下降趋势。它还强调了电力提供商需要在最近通过的通货膨胀法案中利用清洁能源激励措施,并迅速过渡到更清洁的资源,尤其是鉴于,鉴于电力部门必须在国家努力减少其努力的关键近期角色中发挥作用到2030年,总排放量为一半。
该报告是美国100个最大的电力生产商的基准空气排放,发现,美国发电的总体二氧化碳排放量仍比2007年峰值低约34%。发电厂SO2和NOX排放分别比1990年国会通过了《清洁空气法》的重大修正案时,分别低94%和88%。总体而言,包括可再生能源,水力和核能在内的零碳产生正在上升,在2021年在美国全美国电力的40%中的2021年达到了历史最高水平。
“尽管电力部门在我们的二十年分析中显示出明显的改善,但我们需要看到整个行业较大的排放量的加速,以达到我们2030年的减少目标。”Dan Bakal,Ceres气候和能源高级计划主管。“重要的是要认识到我们已经走了多远,但是不可能忽略我们仍然需要走多远才能达到巴黎协定设定的关键2030目标。尽管许多最大的电力生产商宣布了气候承诺和减少碳排放的策略,但迅速的脱碳要求增加了雄心壮志。”
报告显示,随着美国天然气价格上涨,二氧化碳排放量最近的增加也是由于煤炭发电的增加和天然气产生的减少所驱动的。尽管可再生能源的一代在2020年至2021年之间提高了一个百分点,但增加的一小部分是满足全球气候目标的必要年度估计的3%至4%的增长。
在未来几年中,随着《降低通货膨胀法》为风,太阳能和其他无碳电力源和数十亿美元的有针对性的赠款和贷款计划提供税收抵免,在美国将激励可再生能源和其他零碳生成来源。过渡到清洁电力。通过对现有车队的激励措施,该立法还承认核电厂对美国无碳电力供应的贡献。随着运输部门和其他目的使用Electify的运输部门,电力电力预计将占美国能源消耗的份额,这使清洁电网成为通往零净经济的途径的关键部分。
“While heat-trapping carbon emissions rebounded in the power sector last year, compared to 2020 levels in the depths of the pandemic, it's important to note that clean electricity continued forging ahead, reaching all-time highs,” said自然资源国防委员会(NRDC)科学办公室政策分析总监Amanda Levin。“To meet our nation’s climate goals, we must accelerate this ongoing shift to clean energy. The enactment of the Inflation Reduction Act, with its substantial clean energy investments, will help galvanize that move, resulting in bending power sector emissions back down and significantly cutting carbon pollution this decade.”
The annual analysis benchmarks key air pollutant emissions, including nitrogen oxide, sulfur dioxide, carbon dioxide, and mercury, from the 100 largest U.S. power producers. It relies upon publicly reported generation and emissions data from the U.S. Energy Information Administration and the U.S. Environmental Protection Agency and provides a useful record of the sector’s environmental performance. It consistently shows a decoupling of emissions and GDP, demonstrating that economic growth and emissions reductions can go hand in hand.
“电工业具有长期的传统,即利用技术解决我们国家最艰巨的能源挑战,现在我们必须运用同样的创新精神来解决气候危机的令人难以置信的人类损失。”星座总裁兼首席执行官Joe Dominguez,美国最大的无碳能源生产国。“建立在我们始终持续的核车队的基础上,Constellation致力于到2040年从清洁,无排放的资源中生产100%的电力,同时继续投资于脱碳,以使我们的经济脱碳并帮助我们的客户满足其可持续性金博宝怎么注册目标。”
Relying upon the most recent available data, the report includes extensive analysis of company-level emissions and production data from 2020 as well as evaluation of sector-wide trends for 2021. The 100 largest power producers in the United States collectively accounted for more than 80% of the sector’s total generation and reported air emissions across nearly 3,500 owned power plants, while fuel mix, emissions, and emission rates vary widely between companies. Air emissions from power plants are highly concentrated among a small number of producers. For example, nearly a quarter of the electric power industry’s sulfur dioxide and carbon dioxide emissions are emitted by just the top two and top five power producers nationally, respectively.
“电力工业在多年中取得了重要的进步,为我们的客户提供了越来越清洁的能源。”Entergy的可持续性与环境政策副总裁John Weiss金博宝怎么注册。“但是,我们还有更多和必须做的事情,这就是为什么Entergy加速我们向客户和社区所需的低碳和更气候的未来的过渡。这一年度基准继续帮助我们和整个行业负责提供这些结果。”
该报告的其他关键发现包括:
- Power plant mercury air emissions, as reported to the EPA’s Toxic Release Inventory database, have decreased 93% since 2000. The first-ever federal limits on mercury and other hazardous air pollutants from coal-fired power plants went into effect in 2015.
- 90 of the top 100 power producers generated power from zero-carbon resources in 2020.
- 尽管同比下降,但连续第六年下降,但2021年,天然气是美国发电的主要来源(38%),其次是煤炭(22%),该煤炭(22%)的产生率从2020年至2021年。
- Non-hydro renewables made up 13% of total U.S. generation in 2020. Of that, 29% came from solar, 68% from wind, and 3% from geothermal sources.
The benchmarking analysis is a collaborative effort between Ceres; Bank of America Charitable Foundation; power producers Constellation Energy and Entergy; and the Natural Resources Defense Council (NRDC). It is authored by ERM.
