资源简介：
Natural gas vehicles (NGVs) have been promoted in China to mitigate air
pollution, yet our measurements and analyses show that NGV growth in China
may have significant negative impacts on climate change. We conducted
real-world vehicle emission measurements in China and found high methane
emissions from heavy-duty NGVs (90% higher than current emission limits).
These emissions have been ignored in previous emission estimates, leading
to biased results. Applying our observations to life-cycle analyses, we
found that switching to NGVs from conventional vehicles in China has led
to a net increase in greenhouse gas (GHG) emissions since 2000. With
scenario analyses, we also show that the next decade will be critical for
China to reverse the trend with the upcoming China VI standard for
heavy-duty vehicles. Implementing and enforcing the China VI standard is
challenging, and the method demonstrated here can provide critical
information regarding the fleet-level CH4 emissions from NGVs.
