TOKYO -- China leads the world in the number of research papers published on technologies related to the global pivot away from greenhouse gases, and is catching up to the U.S. in terms of the quality and impact, a Nikkei survey shows.
China produced more papers than any other country in 16 of the 18 research areas examined, including solar cells and artificial photosynthesis, in Dutch publisher Elsevier's database of more than 82 million articles across 7,000-plus journals between 2015 and 2020.
