美國去年溫室氣體排放量上升了 6.2%

原因主要源自能源和交通這兩大領域。

CANAKKALE, TURKEY – DECEMBER 17: Wind turbines are seen at the Akfen Renewable Energy Group’s, Canakkale Wind Power Plant,  on December 17, 2021 in Canakkale, Turkey. The Canakkale region of Turkey hosts more than 1000 operating wind turbines. In November, Turkey's installed wind power capacity reached 10,585 megawatts making it the second-largest renewable capacity after hydropower. In October, Turkey ratified the Paris Climate Agreement, becoming the last country in the G-20 group to do so and setting an aim for net-zero emissions by 2053 and a focus on new climate initiatives. However, gas and coal continue to be the primary fuel sources in the energy sector, forcing the government to shift towards renewables, such as geothermal, hydropower, wind and solar energy. Over recent years, Turkey has increased installed capacity of renewable sources of energy as it endeavors to cut its near total dependence on imported petroleum products. Oil and gas imports, much of which are used to generate electricity, have become a significant strain on foreign exchange reserves especially as the country deals with a dire economic crisis with the Turkish lira losing more than 40 percent of its value against the U.S dollar this year. However according to Turkey's Energy and Natural Resources Minister Fatih Donmez, Turkey’s power capacity in renewable energy reached approximately 53,000 megawatts at the end of October, and, on November 11, electricity production from wind power hit a historic daily record, generating 20.1 percent of total power. Turkey’s renewable energy capacity is predicted to grow by 50 percent from 2021 through 2026, according to a recent report by the International Energy Agency (IEA).

根據 Rhodium Group 最新發佈的報告,美國 2021 年全年的溫室氣體排放量較 2020 年上升了 6.2%。這也就意味著,美國距離達成巴黎協定的減排目標又後退了一步。根據該協議,美國應該要在 2030 年結束前達到排放量比 2005 年減少 50% 至 52% 的水平。在 2020 年這項數據為 22.2%,但到了去年,排放量又增加到只比 2005 年少 17.4% 的狀態了。

造成更多排放量的原因,主要源自能源和交通這兩大領域。和 2020 年相比,兩者帶來的排放量分別增加了 6.6% 和 10%。在用電方面,美國去年對燃煤發電的依賴上漲了 17% 之多。同時在疫情期間,人們也更傾向於駕車出行。最終美國能否達到巴黎協定設下的減排目標,可能很大程度上要取決於政府未來在上述兩個領域的政策調整。
