據(jù)能源世界網(wǎng)7月2日倫敦報(bào)道，國際能源署(IEA)周四表示，如果不大幅加快清潔能源創(chuàng)新，到2050年實(shí)現(xiàn)碳排放凈零的全球目標(biāo)將無法實(shí)現(xiàn)。

2015年《巴黎協(xié)定》設(shè)定了一個(gè)目標(biāo)，在本世紀(jì)下半葉遏制全球變暖并達(dá)到凈零排放。

IEA在一份特別報(bào)告中分析了400多種清潔能源技術(shù)，并表示盡管現(xiàn)在使用的可再生技術(shù)可以實(shí)現(xiàn)大量的減排，但僅靠它們本身還不夠。

該報(bào)告發(fā)現(xiàn)，在航運(yùn)、卡車運(yùn)輸、航空和重工業(yè)等行業(yè)，目前幾乎沒有技術(shù)可以將排放降至零。

IEA執(zhí)行董事Fatih Birol對(duì)路透表示：“如果不對(duì)運(yùn)輸部門進(jìn)行脫碳，就不可能實(shí)現(xiàn)氣候目標(biāo)。

他補(bǔ)充道，大約一半的減排需要清潔技術(shù)的重大創(chuàng)新。無論我們對(duì)可再生能源做什么，僅靠它們是不夠的，到2050年實(shí)現(xiàn)零碳排放幾乎是不可能的。

需要?jiǎng)?chuàng)新的四項(xiàng)最關(guān)鍵的清潔技術(shù)是電池技術(shù)、碳捕獲和儲(chǔ)存、生物能源和低碳?xì)洌@些技術(shù)目前大多處于發(fā)展階段和/或成本高昂。

由于導(dǎo)致能源需求大幅下滑，預(yù)計(jì)今年全球二氧化碳排放量將比2019年降低8%，為2010年以來的最低水平。但除非采取行動(dòng)，否則隨著經(jīng)濟(jì)復(fù)蘇，二氧化碳排放量可能會(huì)反彈。

IEA表示，盡管目前用于將新技術(shù)引入市場(chǎng)的資金可能會(huì)減少，但一些國家正在制定的經(jīng)濟(jì)復(fù)蘇計(jì)劃為政府提供了支持清潔能源技術(shù)進(jìn)步的機(jī)會(huì)。

Huge acceleration of clean energy innovation needed to meet net zero target: IEA

A global goal to achieve net zero carbon emissions by 2050 will not be met without a huge acceleration in clean energy innovation, the International Energy Agency (IEA) said on Thursday.

The 2015 Paris Agreement set a target to curb global warming and reach net zero emissions in the second half of the century.

In a special report, the IEA analysed more than 400 clean energy technologies and said that although renewable technologies in use now can deliver a large amount of emissions reductions, they are not enough on their own.

It found that there are currently few technologies available for reducing emissions to zero in sectors such as shipping, trucking, aviation and heavy industries.

"Without decarbonising the transport sector there is no chance whatsoever of meeting climate targets," IEA executive director Fatih Birol told Reuters.

"Around half of emissions reductions that are needed still require major innovation of clean technologies. Whatever we do with renewables will not be enough on their own and it will be all but impossible to meet net zero by 2050," he added.

The four most critical clean technologies needing innovation are battery technologies, carbon capture and storage, bioenergy and low-carbon hydrogen, which are currently mostly in the development phase and/or costly.

Global CO2 emissions are expected to be 8% lower this year than in 2019 - their lowest level since 2010 - as energy demand has slumped due to the coronavirus pandemic, but they are likely to rebound as economies recover unless action is taken.

Although there are likely to be less funds available for bringing new technologies to market right now, economic recovery plans being developed by a range of countries provide an opportunity for governments to support clean energy technology progress, the IEA said.
