據油價網7月9日報道，正如疫情對全球經濟產生了相當大的影響一樣，旅行限制和工業活動的暫停導致了全球排放量前所未有的下降。

根據總部位于赫爾辛基的綜合碳觀測系統(ICOS)的數據顯示，截至4月第一周，碳日排放量較2019年平均水平下降了17%，一些國家的二氧化碳排放量下降了26%。

這是有記錄以來降幅最大的一次，全球排放量已回落至2006年的水平。無論從絕對值還是百分比來看，這一降幅都遠高于歷史上其他類似時刻，如1973年阿拉伯石油禁運、或2008年全球金融危機。

然而，隨著封鎖措施的放松和經濟活動的恢復，排放量也有所增加。

根據ICOS的統計數據顯示，到6月10日，排放量已經反彈到僅比封鎖前低4.7%的水平，而且恢復的速度比許多人預期的要快。

全球能源投資受到影響

這一發展使許多人得出結論，僅靠緊縮措施不足以在促進經濟增長的同時充分減少排放，必須采取有利于環境的解決方案，以確保未來的可持續發展。

泰國可再生能源公司BCPG總裁兼首席執行官Bundit Sapianchai告訴OBG，從政策的角度來看，各國都應該更加積極地推廣綠色能源。疫情通過改變生活方式為綠色能源掃清了道路。

總部設在巴黎的國際能源機構(IEA)于6月份發布的一份報告顯示，今年全球能源投資將下降20%，約4000億美元，這也加大了對更多綠色投資的呼吁。

Covid-19 Could Boost Fossil Fuels, Slow Renewables In Emerging Economies

Just as the pandemic has had an considerable impact on the global economy, travel restrictions and the suspension of industrial activities have led to an unprecedented drop in global emissions.

According to data from the Helsinki-based Integrated Carbon Observation System (ICOS), by the first week of April daily carbon emissions had fallen by 17% against mean 2019 levels, with some countries experiencing a 26% fall in CO2 output.

The fall was the sharpest on record, with global emissions dipping back to 2006 levels. This was a far greater drop in both absolute and percentage terms than was seen at other comparable moments in history, such as the Arab oil embargo of 1973 or the 2008 Global Financial Crisis.

However, as lockdown measures have been eased and economic activity has resumed, emissions have also increased.

ICOS statistics found that by June 10, emissions had rebounded to a level just 4.7% below pre-lockdown levels, with the recovery taking place more quickly than many had expected.

Global energy investment takes a hit

This development has led many to conclude that austerity alone will not be enough to adequately reduce emissions while facilitating economic growth, and that environmentally friendly solutions will be necessary to ensure future sustainable development.

“From a policy perspective, every government should try to promote green energy more aggressively. Covid-19 has cleared a path for green energy by changing lifestyles,” Bundit Sapianchai, president and CEO of Thai renewable energy company BCPG, told OBG.

The call for more green investment was bolstered by the release of a report from the Paris-based International Energy Agency (IEA) in June, which found that global investment in energy was set to fall by 20% – some $400bn – this year.
