Carbon Capture Utilization and Storage (CCUS) technology is an essential component to decarbonize society and reach carbon neutrality. Its success depends on not only technological advances but also people's reaction to it. This study applied traditional content analysis to uncover the CCUS reporting landscape and employed the Socio-Political Evaluation of Energy Deployment (SPEED) framework to explore how different aspects of the CCUS value chain were discussed in Chinese newspapers. A total of 492 news items from November 21st 2002 to May 8th 2021 were identified and analyzed. Results showed that news coverage of CCUS technology in China started in 2005. The media explained the nature and sources of carbon dioxide (CO 2), framed CCUS by various terms, for example, " greengen " and " a clean energy technology ", as well as demonstrated various tones in CCUS. The analysis found 71.3% (N = 351) of newsletters took an affirmative stance towards CCUS. It was also revealed that environmental frames appeared in almost every article, while much less attention was paid to other issues. Moreover, this research demonstrated that CCUS-related policies were driving media coverage closely year by year. However, current news presentations were inadequate due to technical misperceptions and a lack of comprehensive coverage. Therefore, this research proposed a science-for-the-community communication strategy that involved several key factors such as policy guidance, newspaper functions at different levels, journalist training, direct engagement of the public as well as student education. • This paper pioneered to investigate Chinese newspaper coverage of CCUS technology. • The frequency of CCUS inclusion in newspapers was somehow affected by policies in China. • CCUS reporting revolved its emission reduction potential, and CCUS influences on health and safety issues were limited framed. • The current CCUS reporting landscape had misperceptions and lacked comprehensive coverage of the value chain. • A science-for-the-community communication strategy that can make media communication effective was proposed.

National climate targets must be decomposed into key areas to guide mitigation actions. This paper presents a comparative study of China's low-carbon transition pathways at the sectoral level under the nationally determined contribution (NDC) and 2 °C targets, using the energy system model and detailed sectoral information. The results show that each sector plays different roles in terms of emission trends, mitigation potentials, technology roadmaps, investment requirements, and mitigation costs. The power sector is expected to contribute around 50% of the total mitigation. The industry sector has better cost-effective performance, with high mitigation potential and low investment requirement. By contrast, the transport and power sectors account for around 90% of total investment demand. The building and transport sectors have substantial mitigation opportunities that can be realized through technologies with negative mitigation costs. Conversely, the industry sector faces challenges in promoting carbon capture and storage, which has the highest mitigation cost. Compared with the sectoral transition pathways under the NDC target, the 2 °C scenario requires a rapid near-term decarbonization of the power sector and additional emission reductions in end-use sectors. This decarbonization is possible through comprehensive deployment of advanced low-carbon technologies as well as measures that increase investments in low-carbon infrastructure and decrease investments in fossil fuel-based technologies in the power and transport sectors. Therefore, it is important to thoroughly understand the sectoral transition pathways under different climate targets in order to coordinate inter-sectoral actions and resources in a cost-effective manner. • A quantitative study of sectoral low-carbon transition pathways in China was done. • Sectors perform differently in emissions trends, mitigation potential, and cost. • The performance of each sector changes over time and based on climate targets. • Different climate targets imply different technology roadmaps.
