The urgent need to address climate change has led to global efforts towards achieving carbon neutrality. However, it is crucial to recognize the existence of carbon inequity, where certain regions or communities bear a disproportionate burden of carbon emissions compared to others. This paper explores the concept of carbon inequity and highlights the importance of considering driving factors in the pursuit of just energy transition. By examining the socioeconomic, environmental, and policy-related factors that contribute to carbon emissions, a comprehensive understanding of the underlying causes of carbon inequity is gained. The study emphasizes the need to address systemic issues such as economic development patterns, industrial structures, energy consumption habits, and social inequalities that perpetuate carbon inequity. It further discusses the significance of collaborative and inclusive approaches to carbon reduction, focusing on bridging the gap between regions with high and low carbon emissions. Policy implications are derived to guide decision-makers in formulating effective strategies for achieving carbon neutrality while ensuring equity and fairness. By considering both the overarching goal of carbon neutrality and the distributional aspects of carbon emissions, a more holistic and equitable approach can be adopted to accelerate the transition to a sustainable and low-carbon future. • It is crucial to recognize the existence of carbon inequity to address climate change. • This paper explores the concept and importance of carbon inequity of just energy transition. • Policy implications are derived to guide decision-makers while ensuring equity and fairness.

How to achieve the "double carbon" goal in energy systems has been the concern of governments. Integrated energy system (IES) is affected by climate change during his operation, in order to study the impact of climate change on IES and achieve the "double carbon" goal in energy systems, this paper proposes an integrated machine learning(IML) to forecast the long-term load, then investigates IES costs and carbon emissions in relation to climate, followed by the establishment of carbon peak energy system(CPES) and carbon neutral energy system(CNES), finally the honey badger algorithm is used to optimize the configuration of CPES and CNES. The results show that: IML can accurately make load forecasts. Under climate change, changes in load reduce the cost and carbon emissions of IES, and changes in equipment efficiency increase the cost and carbon emissions of IES. When both are considered, the cost and carbon emissions of IES increase by 1.18% and 0.92% per decade respectively. The costs of CPES and CNES increase by 0.93% and 1% respectively for every 10 years earlier than the year of achievement. To meet China's "double carbon" goal, CPES and CNES need to increase their costs by 1.97% and 2% respectively. • Integrated machine learning proposed for long-term load forecasting. • Studied the impact of system equipment efficiency and load with climate change. • Proposing carbon peaking energy system to achieve the carbon peak goal. • Proposed carbon-neutral energy system to achieve carbon neutrality goal. • The increased costs of achieving carbon peak and carbon neutral were studied.

Under the carbon neutrality goal, coal enterprises must seek breakthroughs from abandoned mines, develop new resources in the new era, turn problems into countermeasures, and participate in the carbon emissions market, for contributing to the accomplishment of the national strategic goal of carbon neutrality. To this end, we investigated the relevant national policies and regulations to clarify the boundaries disclosed by the carbon information of enterprises, understood the development direction of carbon storage in abandoned mines, and clarified the transformation and development of carbon storage in abandoned mines. We made a few suggestions: (1) China should learn from its past experience and other countries to develop the energy industry with Chinese characteristics and reform the economic system. (2) Coal enterprises must actively respond to the national carbon information disclosure policy, clarify their own responsibilities and carbon emission boundaries. (3) It is necessary to proactively obtain advanced knowledge and plan carbon storage pathways for abandoned mines. (4) Development problems of coal enterprises should be deduced using cases. The 'dual carbon' goals should be achieved steadily step-by-step. (5) Three measures, i.e. improving the existing resource structure, coordinating the information of abandoned mines, and promoting the cultivation of scientific and technological talents.

As the climate is warming up and climate disasters occur more frequently, China's carbon peak and carbon neutrality targets are gaining attention, with provinces starting to set carbon peak targets and constantly exploring low carbon economic development opportunities. However, the existing evaluation index system mainly focuses on low carbon cities and green cities, and there is no evaluation index system for carbon peak and carbon neutrality. This study adopts a combination of theoretical and empirical research and draws on domestic and international research results to construct the first index system for evaluating China's provincial carbon peak and carbon neutrality. The evaluation index system includes 18 indicators from three dimensions: climate ambition, low carbon status, and emissions trends. Using this index system, we calculated the carbon peak and carbon neutrality indices of 30 Chinese provinces. Further, the 30 provinces were classified into six categories, and corresponding policy recommendations for achieving the "Dual carbon" targets were put forward. The evaluation index system constructed in this paper can provide a reference for future carbon peak and carbon neutrality assessments. By disclosing the integrated index of each province, we hope to effectively curb the increasing local carbon emissions; avert inaction in areas with good natural endowments; and motivate the advancement of the latter, to boost the implementation of the "Dual carbon" targets coherently for the whole country. [Display omitted] • An integrated evaluation system on China's Provincial "Dual carbon" was proposed. • 30 provinces in mainland China were ranked based on the integrated index. • 6 groups were classified to show provincial differences on dual carbon performance. • Policy recommendations to fulfill China's climate commitment were put forward.

Due to large energy consumption and carbon emissions (ECCE) in the building sector, there is huge potential for carbon emission reduction, and this will strongly influence peak carbon emissions and carbon neutrality in the future. To get a better sense of the current research situation and future trends and to provide a valuable reference and guidance for subsequent research, this study presents a summary of carbon peak and carbon neutrality (CPCN) in buildings using a bibliometric approach. Three areas are addressed in the review through the analysis of 364 articles published from 1990–2021: (1) Which countries, institutions, and individuals have conducted extensive and in-depth research on CPCN in buildings, and what is the status quo of their collaboration and contributions? (2) What subjects and topics have aroused wide interest and enthusiasm among scholars, and what are their time trajectories? (3) What journals and authors have grabbed the attention of many scholars, and what are the research directions related to them? Moreover, we propose future research directions. Filling these gaps will enrich the research body of CPCN and overcome current limitations by developing more methods and exploring other practical applications. [ABSTRACT FROM AUTHOR]
