Achieving carbon-neutrality has become a global agenda following the ratification of the Paris Agreement. For the developing countries, in particular, attaining a low-carbon economy is particularly important since these economies are predominantly fossil-fuel dependent, to which Bangladesh is no exception. Therefore, this study specifically aimed at evaluating the environmental impacts associated with energy consumption and other key macroeconomic variables in the context of Bangladesh over the 1975–2016 period. As opposed to the conventional practice of using carbon dioxide emissions to proxy environmental quality, this study makes a novel attempt to use the carbon footprints to measure environmental welfare in Bangldesh. The outcomes from this study are expected to facilitate the carbon-neutrality objective of Bangladesh and, therefore, enable the nation to comply with its commitments concerning the attainment of the targets enlisted under the Paris Agreement and the United Nations Sustainable Development Goals declarations. The econometric analysis involved the application of methods that are suitable for handling the structural break issues in the data. The overall findings from empirical exercises reveal that aggregate energy consumption, fossil fuel consumption, and natural gas consumption boost the carbon footprint figures of Bangladesh. In contrast, nonfossil fuel consumption and hydroelectricity consumption are witnessed to abate the carbon footprint levels. Besides, economic growth and international trade are also evidenced to further increase the carbon footprints. Hence, these findings suggest that a clean energy transition within the Bangladesh economy can be the panacea to the nation's persitently aggravating environmental hardships. Furthermore, the causality analysis confirmed the presence of unidirectional causalities stemming from total energy consumption, fossil fuel consumption, natural gas consumption, hydroelectricity consumption, economic growth, and international trade to the carbon footprints. On the other hand, nonfossil fuel consumption is found to be bidirectionally associated with carbon footprints. In line with these aforementioned findings, several key policy suggestions are put forward regarding the facilitation of the carbon-neutrality agenda in Bangladesh.

CO 2 capture, utilization, and storage (CCUS) technology is a rare option for the large-scale use of fossil fuels in a low-carbon way, which will definitely play a part in the journey towards carbon neutrality. Within the CCUS nexus, CCU is especially interesting because these processes will establish a new “atmosphere-to-atmosphere” carbon cycle and thus indirectly offer huge potential in carbon reduction. This study focuses on the new positioning of CCUS in the carbon neutrality scenario and aims to identify potential cutting-edge/disruptive CCU technologies that may find important application opportunities during the decarbonization of the energy and industrial system. To this end, direct air capture (DAC), flexible metal-framework materials (MOFs) for CO 2 capture, integrated CO 2 capture and conversion (ICCC), and electrocatalytic CO 2 reduction (ECR) were selected, and their general introduction, the importance to carbon neutrality, and most up-to-date research progress are summarized.

China’s recently announced directive on tackling climate change, namely, to reach carbon peak by 2030 and to achieve carbon neutrality by 2060, has led to an unprecedented nationwide response among the academia and industry. Under such a directive, a rapid increase in the grid penetration rate of solar in the near future can be fully anticipated. Although solar radiation is an atmospheric process, its utilization, as to produce electricity, has hitherto been handled by engineers. In that, it is thought important to bridge the two fields, atmospheric sciences and solar engineering, for the common good of carbon neutrality. In this überreview, all major aspects pertaining to solar resource assessment and forecasting are discussed in brief. Given the size of the topic at hand, instead of presenting technical details, which would be overly lengthy and repetitive, the overarching goal of this review is to comprehensively compile a catalog of some recent, and some not so recent, review papers, so that the interested readers can explore the details on their own.

On 22 September 2020, within the backdrop of the COVID-19 global pandemic, China announced its climate goal for peak carbon emissions before 2030 and to reach carbon neutrality before 2060. This carbon-neutral goal is generally considered to cover all anthropogenic greenhouse gases. The planning effort is now in full swing in China, but the pathway to decarbonization is unclear. The needed transition towards non-fossil fuel energy and its impact on China and the world may be more profound than its reform and development over the past 40 years, but the challenges are enormous. Analysis of four representative scenarios shows significant differences in achieving the carbon-neutral goal, particularly the contribution of non-fossil fuel energy sources. The high target values for nuclear, wind, and bioenergy have approached their corresponding resource limitations, with solar energy being the exception, suggesting solar's critical role. We also found that the near-term policies that allow for a gradual transition, followed by more drastic changes after 2030, can eventually reach the carbon-neutral goal and lead to less of a reduction in cumulative emissions, thus inconsistent with the IPCC 1.5°C scenario. The challenges and prospects are discussed in the historical context of China's socio-economic reform, globalization, international collaboration, and development.

China’s newly announced carbon neutrality goal manifests its determination to advance green and low-carbon development. The country aims to peak carbon dioxide emissions by 2030 and achieve carbon neutrality by 2060. Consequently, guidelines and action plans have been actively deployed and issued. The carbon neutrality commitment (vision) and its detailed deployment (action) would contribute to climate change mitigation and corporate market value. Therefore, we categorize the carbon neutrality-related events and analyze their impacts on the stock market from July 2020 to March 2021. The main findings are as follows: (1) The action event have increased the carbon neutrality-related stocks by 0.04%, while that of the vision event is  – 0.003%, indicating that investors’ confidence increases when the carbon neutrality commitment is accompanied by specific and detailed guidelines. (2) The impact of carbon neutrality announcement becomes more positive and significant after related events occur repeatedly. (3) Carbon neutrality-related power industry and state-owned enterprises are potential beneficiaries of this decarbonization goal. Our study supplements the literature on climate policy and its economic value, potentially contributing to the next stage of global decarbonization.

Transportation carbon emission reduction has become an important driving point for China to achieve carbon peak and carbon neutrality. Based on the three-dimensional grey correlation analysis model, taking the five factors affecting transportation carbon emissions, namely, population, GDP, tertiary industry, energy structure and logistics scale, as the research object, the transportation carbon emissions of China’s low-carbon pilot and nonpilot provinces from 2010 to 2019 are calculated based on the Intergovernmental Panel on Climate Change (IPCC) carbon emission accounting method. The time series grey correlation degree and regional grey correlation degree of each influencing factor and traffic carbon emission are obtained using the provincial data, so as to provide policy suggestions for China to achieve the goal of “carbon peak and carbon neutrality” in the field of transportation. The results show that the descending order of the five influencing factors on transportation carbon emissions is: energy structure, logistics scale, population, GDP and tertiary industry. From 2010 to 2019, the time series grey correlation degree between the five influencing factors and transportation carbon emissions shows a fluctuating downward trend, but the impact of demographic factors has become more and more obvious in the past two years; According to the difference of grey correlation degree in different regions, the traffic development of various provinces in China is different, so it is necessary to formulate relevant policies individually.

First, a brief introduction is made to the four basic judgments and understandings of the goals of \"carbon peaking and carbon neutrality.\" Then, an in-depth elaboration is provided on the eight major strategies for achieving the goals of \"carbon peaking and carbon neutrality,\" including conservation and efficiency priority, energy security, non-fossil energy substitution, re-electrification, resource recycling, carbon sequestration, digitalization and cooperation between countries. Next, eight major implementation paths for achieving the goals of \"carbon peaking and carbon neutrality\" are discussed in detail, including industrial restructuring; building a clean, low-carbon, safe and efficient energy system, and renewing the understanding of China's energy resource endowment; accelerating the construction of a new-type power system with a gradually growing proportion of new energy, and realizing the \"possible triangle\" of high-quality energy system development; utilizing electrification and deep decarbonization technologies to promote the orderly peaking and gradual neutralization of carbon emissions in the industrial sector; promoting the low-carbon transition of transportation vehicles to achieve carbon peaking and carbon neutrality in the transportation sector; focusing on breaking through key green building technologies to achieve zero carbon emissions from building electricity and heat; providing a strong technical support for carbon removal to achieve carbon neutrality; accelerating the construction of the integrated planning and assessment mechanism for pollution and carbon reduction, establishing a sound strategy, planning, policy and action system, and optimizing the carbon trading system. Afterwards, it is particularly pointed out that the realization of the goals of \"carbon peaking and carbon neutrality\" cannot be separated from the support of sci-tech innovation. Finally, it is stressed that carbon neutrality is not the end, but an important milestone. If viewed from the perspective of future energy, the significance and historical status of the goals of \"carbon peaking and carbon neutrality\" will be more understandable.

China has been committed to achieving carbon neutrality by 2060. China's pledge of carbon neutrality will play an essential role in galvanising global climate action, which has been largely deferred by the Covid-19 pandemic. China's carbon neutrality could reduce global warming by approximately 0.2-0.3 °C and save around 1.8 million people from premature death due to air pollution. Along with domestic benefits, China's pledge of carbon neutrality is a \"game-changer\" for global climate action and can inspire other large carbon emitters to contribute actively to mitigate carbon emissions, particularly countries along the Belt and Road Initiative (BRI) routes. In order to achieve carbon neutrality by 2060, it is necessary to decarbonise all sectors in China, including energy, industry, transportation, construction, and agriculture. However, this transition will be very challenging, because major technological breakthroughs and large-scale investments are required. Strong policies and implementation plans are essential, including sustainable demand, decarbonizing electricity, electrification, fuel switching, and negative emissions. In particular, if China can peak carbon emissions earlier, it can lower the costs of the carbon neutral transition and make it easier to do so over a longer time horizon. China's pledge of carbon neutrality by 2060 and recent pledges at the 26 th UN Climate Change Conference of the Parties (COP26) are significant contributions and critical steps for global climate action. However, countries worldwide need to achieve carbon neutrality to keep the global temperature from growing beyond the level that will cause catastrophic damages globally.

Abstract China’s pledge to reach carbon neutrality before 2060 is an ambitious goal and could provide the world with much-needed leadership on how to limit warming to +1.5°C warming above preindustrial levels by the end of the century. But the pathways that would achieve net zero by 2060 are still unclear, including the role of negative emissions technologies. We use the Global Change Analysis Model to simulate how negative emissions technologies, in general, and direct air capture (DAC) in particular, could contribute to China’s meeting this target. Our results show that negative emissions could play a large role, offsetting on the order of 3 GtCO2 per year from difficult-to-mitigate sectors, such as freight transportation and heavy industry. This includes up to a 1.6 GtCO2 per year contribution from DAC, constituting up to 60% of total projected negative emissions in China. But DAC, like bioenergy with carbon capture and storage and afforestation, has not yet been demonstrated anywhere approaching the scales required to meaningfully contribute to climate mitigation. Deploying NETs at these scales will have widespread impacts on financial systems and natural resources, such as water, land and energy in China.

Carbon neutrality is a critical pathway to achieving a sustainable future. Investigating the driving factors for carbon neutrality can provide empirical evidence to support ecosystem protection. Prior studies used mean regression to investigate carbon neutrality, concealing the heterogeneity of carbon neutrality. In this paper, we introduce a dynamic spatial Durbin quantile regression (DSDQR) model along with its estimation method, and derive the marginal effect formulas for independent variables at different quantiles. Then we apply this methodology to examine the impact mechanisms of environmental governance pressure, economic growth, and their interaction effects on carbon neutrality performance using Chinese provincial data spanning 2011–2022. Key findings include: (1) Temporal, spatial, and path dependencies in carbon neutrality performance are prevalent across nearly all provinces. (2) Environmental governance pressure exhibits an inhibitory short-term effect on carbon neutrality in provinces at medium and low quantiles, while it has a positive long-term impact in high quantile provinces. (3) Economic growth generally hinders carbon neutrality performance in most provinces. However, economic growth in high quantile provinces exerts a positive long-term influence on carbon neutrality performance after the COVID-19 pandemic. (4) The interaction between environmental governance pressure and economic growth demonstrates a significant positive short-term impact on carbon neutrality performance post-epidemic, yet it has a negative long-term effect in high quantile provinces. Finally, this article calls for differentiated decarbonization strategies based on provincial carbon neutrality development stages.
