据能源世界网7月2日伦敦报道,国际能源署(IEA)周四表示,如果不大幅加快清洁能源创新,到2050年实现碳排放净零的全球目标将无法实现。
2015年《巴黎协定》设定了一个目标,在本世纪下半叶遏制全球变暖并达到净零排放。
IEA在一份特别报告中分析了400多种清洁能源技术,并表示尽管现在使用的可再生技术可以实现大量的减排,但仅靠它们本身还不够。
该报告发现,在航运、卡车运输、航空和重工业等行业,目前几乎没有技术可以将排放降至零。
IEA执行董事Fatih Birol对路透表示:“如果不对运输部门进行脱碳,就不可能实现气候目标。
他补充道,大约一半的减排需要清洁技术的重大创新。无论我们对可再生能源做什么,仅靠它们是不够的,到2050年实现零碳排放几乎是不可能的。
需要创新的四项最关键的清洁技术是电池技术、碳捕获和储存、生物能源和低碳氢,这些技术目前大多处于发展阶段和/或成本高昂。
由于导致能源需求大幅下滑,预计今年全球二氧化碳排放量将比2019年降低8%,为2010年以来的最低水平。但除非采取行动,否则随着经济复苏,二氧化碳排放量可能会反弹。
IEA表示,尽管目前用于将新技术引入市场的资金可能会减少,但一些国家正在制定的经济复苏计划为政府提供了支持清洁能源技术进步的机会。

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.
