據油價網7月22日消息稱，彭博新能源財經在周三發布的《2021年新能源展望》報告中表示，如果想在2050年前實現凈零碳排放，未來30年，世界需要在綠色能源基礎設施和供應方面投資173萬億美元。

　　根據BNEF的數據，如果各國政府和企業想要實現他們近幾個月來競相承諾的2050年凈零排放目標，他們需要在未來30年投資92萬億美元至173萬億美元。

　　該研究公司表示，要想在2050年實現與凈零世界相適應的能源轉型，需要迅速擴大投資，并補充說，“實現凈零的途徑仍不確定。”

　　根據BNEF的說法，為了實現凈零排放，全世界每年需要增加一倍以上的投資。這些投資將從目前每年約1.7萬億美元躍升至“未來30年平均每年3.1萬億至5.8萬億美元之間”。

　　BNEF認為，這十年對于讓世界走上實現《巴黎協定》目標的軌道至關重要。

　　BNEF首席經濟學家Seb Henbest說：“沒有時間可以浪費了。如果世界要在本世紀中葉實現或接近實現凈零排放，那么我們需要加快部署這十年的低碳解決方案——這意味著更多的風能、太陽能、電池和電動汽車，以及用于建筑物的熱泵，工業上的回收和更多的電力使用，以及將生物燃料用于航運和航空。”

　　BNEF表示，資本支出將為投資者和金融機構創造機會，但沒有具體說明誰將為這筆巨額支出買單。

　　如果世界要將全球變暖控制在2攝氏度或以下，它總共需要至少 30 萬億至 40 萬億美元的投資，用于能源系統和鋼鐵和水泥制造業等眾所周知難以減少排放的行業的脫碳。這是Wood Mackenzie對支持越來越多國家實現能源轉型和凈零排放愿望所需投資的最低估計。

　　Net-Zero 2050 May Need Up To $173 Trillion Investments

　　The world will need to invest up to $173 trillion in greener energy infrastructure and supply over the next 30 years if it wants to achieve net-zero carbon emissions by 2050, BloombergNEF said in its New Energy Outlook 2021 report published on Wednesday.

　　If governments and companies want to see the coveted 2050 net-zero emissions they have been racing to pledge in recent months, they would need to invest between $92 trillion and $173 trillion in the next three decades, according to BNEF.

　　The energy transition that would be compatible with a net-zero world in 2050 would need rapid scaling of investment, the research firm says, adding that “the route to net-zero remains yet uncertain.”

　　According to BNEF, the world needs to more than double yearly investments in order to achieve net-zero emissions. Those investments should jump from around $1.7 trillion annually at present to “somewhere between $3.1 trillion and $5.8 trillion per year on average over the next three decades.”

　　BNEF believes that this decade will be critical to set the world on a track that could allow it to reach the Paris Agreement targets.

　　“There is no time to waste. If the world is to achieve or get close to meeting net-zero by mid-century, then we need to accelerate deployment of the low-carbon solutions we have this decade – that means even more wind, solar, batteries, and electric vehicles, as well as heat pumps for buildings, recycling and greater electricity use in industry, and redirecting biofuels to shipping and aviation,” BNEF chief economist Seb Henbest said.

　　Capital expenditures will create opportunities for investors and financial institutions, BNEF says, but didn’t specify who will foot the enormous bill.

　　If the world is to come anywhere close to limiting global warming to 2 degrees Celsius or below, it will need, collectively, a bare minimum of $30 trillion to $40 trillion of investment in energy systems and decarbonization of industries where emissions are notoriously hard to abate such as steel and cement making. That’s Wood Mackenzie’s bare-minimum estimate of investments needed to support the energy transition and the net-zero emission aspirations of a growing number of countries.
