“…If the world does not implement a series of measures to control global warming, human beings will confront environmental deterioration, including increased global temperatures, more frequent extreme weather, and significant harm to land and marine ecosystems (Zou et al 2021 ). If global temperatures rise by 2 °C, around 13% of terrestrial ecosystems will be destroyed, and many animals and plants will become extinct; sea levels will rise by approximately 36 to 87 cm, and approximately 95% of coral reefs will face extinction (IPCC 2018 ).…”

The increasing global industrialization and over-exploitation of fossil fuels has induced the release of greenhouse gases, leading to an increase in global temperature and causing environmental issues. There is therefore an urgent necessity to reach net-zero carbon emissions. Only 4.5% of countries have achieved carbon neutrality, and most countries are still planning to do so by 2050–2070. Moreover, synergies between different countries have hampered synergies between adaptation and mitigation policies, as well as their co-benefits. Here, we present a strategy to reach a carbon neutral economy by examining the outcome goals of the 26th summit of the United Nations Climate Change Conference of the Parties (COP 26). Methods have been designed for mapping carbon emissions, such as input–output models, spatial systems, geographic information system maps, light detection and ranging techniques, and logarithmic mean divisia. We present decarbonization technologies and initiatives, and negative emissions technologies, and we discuss carbon trading and carbon tax. We propose plans for carbon neutrality such as shifting away from fossil fuels toward renewable energy, and the development of low-carbon technologies, low-carbon agriculture, changing dietary habits and increasing the value of food and agricultural waste. Developing resilient buildings and cities, introducing decentralized energy systems, and the electrification of the transportation sector is also necessary. We also review the life cycle analysis of carbon neutral systems.

“…The existence of a carbon emissions peak means that there will be a steady decline in carbon emissions after reaching a plateau [13]. Carbon neutrality refers to the total amount of greenhouse gas emissions produced by an enterprise, organization, or individual within a certain amount of time and the realization of a zero-carbon emissions status by offsetting these carbon emissions through forest planting, energy saving, and emission reduction [14,15]. Developed countries and major economies have developed their own targets to curb greenhouse gas emissions and are trying to do their part [16][17][18][19][20].…”

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.

“…More than 120 countries have successively proposed their carbon neutral plans: the major industrialized countries, most European Union countries, the US, etc., aim to achieve the target mostly by 2050 [ 3 , 4 ]; China is the leading developing country striving to the carbon mitigation, pledging to reach carbon peak before 2030 and achieve carbon neutralization by 2060 [ 5 ]. The decarbonization plan would bring profound benefits to the environmental sustainability [ 6 , 7 ], air quality [ 8 – 11 ], and human’s health; however, the related social impacts and technical constraints pose challenges to the rapid transition towards a carbon-neutral society from a fossil-based industrial and economic system [ 7 , 12 , 13 ].…”

Coal consumption leads to over 15 billion tons of global CO2 emissions annually, which will continue at a considerable intensity in the foreseeable future. To remove the huge amount of CO2, a practically feasible way of direct carbon mitigation, instead of capturing that from dilute tail gases, should be developed; as intended, we developed two innovative supporting technologies, of which the status, strengths, applications, and perspective are discussed in this paper. One is supercritical water gasification-based coal/biomass utilization technology, which orderly converts chemical energy of coal and low-grade heat into hydrogen energy, and can achieve poly-generation of steam, heat, hydrogen, power, pure CO2, and minerals. The other one is the renewables-powered CO2 reduction techniques, which uses CO2 as the resource for carbon-based fuel production. When combining the above two technical loops, one can achieve a full resource utilization and zero CO2 emission, making it a practically feasible way for China and global countries to achieve carbon neutrality while creating substantial domestic benefits of economic growth, competitiveness, well-beings, and new industries.
