JIAO, Nianzhi (2021): Developing Ocean Negative Carbon Emission Technology to Support National Carbon Neutralization

JIAO, Nianzhi (2021): Developing Ocean Negative Carbon Emission Technology to Support National Carbon Neutralization. In Bulletin of Chinese Academy of Sciences (Chinese Version) 36 (2), pp. 179–187. DOI: 10.16418/j.issn.1000-3045.20210123001.

"We have established marine carbon sequestration theory, which has laid solid foundation for negative emission and set up the linkage between science and policy. At present, China should take the lead of the international program on the ocean negative carbon emission (ONCE), and put it into practice through top design, timely layout, and development of ONCE technology, and then establish ONCE protocols and standards for carbon trade."

Zhou, Hewen; et al. (2021): Prospective contributions of biomass pyrolysis to China’s 2050 carbon reduction and renewable energy goals

Zhou, Hewen; Bartocci, Pietro; Fantozzi, Francesco; Mašek, Ondřej; Agblevor, Foster; Wei, Zhiyu et al. (2021): Prospective contributions of biomass pyrolysis to China’s 2050 carbon reduction and renewable energy goals. In nature communications.

"While bioenergy with carbon capture and storage (BECCS) may need years to mature, this study focuses on developing a ready-to-implement biomass intermediate pyrolysis poly-generation (BIPP) technology to produce a potentially stable form of biochar, a medium for carbon storage, and to provide a significant source of valuable biofuels, especially pyrolysis gas."

Dai, Zhen; et al. (2021): Elicitation of US and Chinese expert judgments show consistent views on solar geoengineering

Dai, Zhen; Burns, Elizabeth T.; Irvine, Peter J.; Tingley, Dustin H.; Xu, Jianhua; Keith, David W. (2021): Elicitation of US and Chinese expert judgments show consistent views on solar geoengineering. In Humanit Soc Sci Commun 8 (1), pp. 1–9. DOI: 10.1057/s41599-020-00694-6.

"We performed face-to-face interviews using formal expert elicitation methods with 13 US and 13 Chinese climate experts randomly selected from IPCC authors or supplemented by snowball sampling. We compare their judgments on climate change, SG research, governance, and deployment."

Wang, Jing; et al. (2020): Large Chinese land carbon sink estimated from atmospheric carbon dioxide data

Wang, Jing; Feng, Liang; Palmer, Paul I.; Liu, Yi; Fang, Shuangxi; Bösch, Hartmut et al. (2020): Large Chinese land carbon sink estimated from atmospheric carbon dioxide data. In Nature 586 (7831), pp. 720–723. DOI: 10.1038/s41586-020-2849-9.

"Here we present recently available data on the atmospheric mole fraction of CO2, measured from six sites across China during 2009 to 2016. Using these data, we estimate a mean Chinese land biosphere sink of −1.11 ± 0.38 petagrams of carbon per year during 2010 to 2016, equivalent to about 45 per cent of our estimate of annual Chinese anthropogenic emissions over that period."

Feng, Dongdong; et al. (2020): Review of Carbon Fixation Evaluation and Emission Reduction Effectiveness for Biochar in China

Feng, Dongdong; Wang, Shizhang; Zhang, Yu; Zhao, Yijun; Sun, Shaozeng; Chang, Guozhang et al. (2020): Review of Carbon Fixation Evaluation and Emission Reduction Effectiveness for Biochar in China. In Energy Fuels 34 (9), pp. 10583–10606. DOI: 10.1021/acs.energyfuels.0c02396.

"As the world’s largest energy consumer (i.e., 24% of the world) and one of the largest biomass resource reserve countries (i.e., total reserves of 73.42 × 108 t a–1), for China, using biomass to prepare for biochar and store it in soil to realize the “carbon sequestration and emission reduction” is of great significance. This paper explores the physical–chemical properties of biochar and finds out its reason–manifestation–influencing factors for “carbon sequestration reduction”."
