Assuming responsibility for emission reduction is an important part of participating in the global governance of climate change. Countries with a carbon neutrality target now cover about 75% of global greenhouse gas emissions. Carrying out fairness evaluations of their carbon neutrality targets provide a strong basis for the global carbon inventory. In this paper, the target years of carbon neutrality for major countries and regions under the global target of 2 °C and 1.5 °C are studied using the burden sharing model. On this basis, this paper simulates the possible pathways of carbon neutrality and evaluates the ambition of emission reduction targets in terms of annual emission reduction, per capita emission, and cumulative per capita emission. The results show that, from the perspective of equity, most of the developing countries cannot meet the global goal of 1.5 °C. The United States and the European Union nations could achieve carbon neutrality by 2050 by continuing their annual emission reductions under their existing NDC targets. However, to achieve carbon neutrality by 2060, China's annual emission reduction rate from 2030 to 2050 will be 6.7%, and the annual amount of emission reduction accounts for 51% of the global amount under the 1.5 °C target. Meanwhile, China would become the main force behind global cumulative emissions in the following decades. Thus, the emission reduction pathways China chooses will have an important impact on global climate mitigation progress. Based on the above research conclusions, this paper proposes that developed countries and developing countries should explore bilateral or multilateral cooperation in technology and finance in the field of climate change. Under the great pressure to achieve carbon neutrality, China needs to carry out research on the overall emission reduction pathways as soon as possible and clarify the paths at the scale of sectors, industries, provinces, and time stages.

In this paper, ecological cement-based materials were prepared based on a large amount of EMR to provide a potential scheme for accelerating the digestion of EMR. Firstly, the performance change from low consumption and harmless pretreatment of EMR was discussed. Then the mechanical properties and water resistance of cement mortar pretreated with EMR were studied. Finally, the corresponding economic and environmental effects were analyzed. The results show th.at the particle size of EMR becomes smaller after lime and ball milling, and the phase of (NH4)2SO4 in EMR transforms into gypsum phase. The removal rates of Mn2+ and NH4+--N reached 98.69% and 96.46%, realizing the harmless treatment of EMR. When the content of EMR reaches 70% and the cement-sand ratio is 1:2, the mechanical properties and durability of cement-based materials are good. Compared with M15 mortar prepared with pure cement, EMR-cement mortar can achieve 17.6% economic saving and 36.8% greenhouse gas emission reduction. The research results can provide important technical support for the application of EMR in roadbed reinforcement and road cement stabilization base, and realize the efficient and low-carbon utilization of EMR waste.

In the context of climate change, nature-based solutions (NbS) are an advanced concept for human society to cope with climate risks and challenges; they can also help to build a scientific and standardized management system and an efficient and green social and economic system for the achievement of sustainable and high-quality development goals. Besides, it provides the fundamental guidelines and directions for the Xiong' an New Area, which has been planned and constructed with high standards and provides an important realistic scenario for the study of stormwater management modes. This paper introduces the concept and development process of NbS, summarizes its principles and approaches, and systematically analyzes the characteristics of rainstorm and flood disasters in the Xiong' an New Area and the tight situation of water supply and demand caused by rapid socioeconomic development against the background of frequent extreme weather events caused by climate change. Based on the moderate greenhouse gas emission scenario (RCP4.5) of the regional climate model, the numerical simulation results of 1980--2099 with a horizontal resolution of 25 km, and the reference period of 1986--2005, the future climate change prediction analysis and rainstorm and flood risk assessment in the Xiong' an New Area were carried out. According to the Xiong' an New Area' s stormwater management and the current extreme rainfall situation, the paper combines the future social and economic development and urban-rural ecological spatial pattern of the Xiong' an New Area, as well as the concept and construction goals of 'building an ecological city where human and nature coexist harmoniously in the lake city featuring blue sky and verdant fields,' and proposes nature-based solutions to strengthen climate risk management in the area and reduce the risk of extreme precipitation. The proposed stormwater management model for the Xiong' an New Area based on NbS includes three dimensions: ① We should adhere to the overall plan of ecological protection and restoration of the whole basin and improve the capacity of systemic climate governance. ② We should advocate the multi-scale vertical system design at the city level and improve the carrying capacity of urban resilience. ③ We should adhere to the general principle of seeking advantages and avoiding disadvantages and strengthen the development of ecological infrastructure. On the basis of effective engineering and institutional defense measures, actively implementing the concept of nature-based solutions in the stormwater management of the Xiong' an New Area is conducive to fully exploring and rationally utilizing the special water system conditions of the area and the integrated environmental advantages of urban lakes, seeking advantages and avoiding disadvantages, and minimizing the impact of extreme precipitation on the stable operation of the cities and the safety of people' s lives and property.

Carbon emission from crop production is one of the important sources of greenhouse gas emission in China, and it is a hot issue on agricultural ecological environment in recent years. Based on the statistical data of agricultural production input, crop yield, cultivated land area and crop sowing area in Hebei province from 2010 to 2018, this paper studied the dynamic changes of carbon emission of crop production inputs, and analyzed the proportion of carbon emission for each different crop production inputs, so as to provide a theoretical basis for energy conservation and emission reduction in agricultural production, and in the end to realize the low-carbon agriculture. The results showed that from 2010 to 2018, the carbon emission from crop production in Hebei province took 2015 as the turning point, showing a trend of increasing first and then decreasing. From 2010 to 2018, the total carbon emissions from crop production, carbon emissions per unit yield and carbon emissions per unit cultivated land area in Hebei province were 22.19-104-26.74x104tCO2 eq, 0.21-0.30tCO2eq·t-1 and 3.40-4.10tCO2eq·ha-1, respectively. The total carbon emission of crop production, carbon emission per unit yield and carbon emission per unit cultivated land area in 2018 were the lowest, decreasing by 17.0%, 30.0% and 17.0% respectively compared with the highest value. The 9-year average carbon emission of chemical fertilizer, pesticide, agricultural film, diesel fuel and irrigation electricity accounted for 38.6%, 2.1%, 11.5%, 34.7% and 13.1%, respectively. Chemical fertilizer and diesel fuel were the main sources of agricultural carbon emission, accounting for more than 30%. The dynamic change of carbon emission of crop production inputs was obviously affected by the national policies. It is suggested that the carbon emissions from agricultural production should be guided by national policies, and measures such as formulating mature agricultural management system, strengthening agricultural technology training and promoting the application of advanced cultivation techniques should be taken to reduce the carbon emissions from agricultural sources, so as to promote the green development of agriculture.

Global climate change caused by excessive greenhouse gas（GHG） emissions has been widely concerned. Agricultural activities are the second largest source of GHGs emissions, so it is urgent to reduce agricultural GHGs emissions. Biochar, which has stable properties, abundant aromatic carbon and pores, is produced by pyrolysis of biomass under high temperature and limited oxygen conditions. The effect of biochar amendment on GHGs mitigation and soil carbon sequestration is excellent, and biochar application has the potential to participate in China’s ongoing carbon trading of voluntary emission reduction（VER）. However, the factors affecting the carbon sequestration and GHGs emission reduction effect of biochar are complicated, so it is necessary to systematically summarize the mitigation effect, influencing factors and research progress of biochar. This paper reviewed researches on the GHGs emission reduction and carbon sequestration effect of biochar through pot and field experiment as well as meta-analysis research. At the same time, CiteSpace software was used for visual analysis to explore the research hotspots and development trends in this field. The opportunities and challenges faced by biochar application projects participating in carbon trading were summarized based on the characteristics of domestic and foreign carbon trading market development and corresponding supporting policies. Corresponding solutions were also provided in this study, which offered scientific guidance and useful reference for the development of carbon sequestration and GHGs emission reduction research of biochar and the successful participation of biochar application projects in carbon trading.

Textile printing and dyeing industry is one of the industrial industries with the largest discharge of wastewater and pollutants. It is also featured by energy-intensive and high-carbon emission characteristics. Low-carbon wastewater treatment has become an important path for sustainable development. Based on the analysis of the greenhouse gas emission characteristics of printing and dyeing wastewater treatment process, the concept of carbon emission potential in terms of used dyes was proposed. To address the complexity and variability of wastewater treatment process and wastewater quality, an accurate estimation method of carbon emission in wastewater treatment process was established according to carbon and nitrogen mass balance. The progress and development direction of low-carbon treatment technology for textile printing and dyeing wastewater were summarized in this paper.

This paper, focusing on liberalism and justice, mainly discussed the historical limitations and profit -- driven nature of carbon politics, which operates on climate agreements. Based on the external characteristics of greenhouse gas emission, the governance of international anarchy and the constraint of national limited rational behaviors, the paper elaborated on the necessity and good visions of establishing a cooperative mechanism of carbon politics. However, the deprivation of modern rules on carbon politics suggested the capital and interest demands of climate change politics, and carbon politics in the name of climate distribution justice was represented by the effectiveness of technological ownership and market share. Therefore, the current global environmental governance system mainly speaks for the interests and ideologies of the developed countries and the very requests from the environment itself have been referred back.

A key problem in prediction theory is to improve adaptiveness to data characteristics. This paper proposed a novel method called buffered adaptive grey rolling model or BARGM model, which combines the buffer operator and grey rolling model. First, the new model decomposes original sequence into continuous data slices, and uses feedback input to adjust modeling data by buffer operator with variable weight on each data slice, then a extended grey forecasting model is utilized to model the adjusted data slices stepwisely and generate the extrapolation values. With comparison to GM(1. 1). BARGM lias two obvious features: Changing the monotonicity of traditional time response function and strong expansibility. The case study uses the BARGM and benchmark models to analyze China's greenhouse gas emission data, and the results demonstrate that the accuracy of fitting and prediction improve obviously, and prove the new model's effectiveness.

Atmospheric carbon dioxide( CO2) enrichment constitutes as one of the primary components of human-induced global change, significantly shaping soil carbon( C)and nitrogen( N)biogeochemieal cycles. Plant photosynthesis and growth are expected to increase under elevated atmospheric CO2 and ultimately promote the enhancement of soil Cstorage. On the other hand, soil C input enhanced by elevated atmospheric CO2 may also increase soil CO2 emissions, stimulating some soil Orelease back to the atmosphere. However, to what extent the capacity of terrestrial ecosystems acting as a sink under elevated CO2may be offset by the enhancement of soil source strength of greenhouse gases( GHG) emissions remains largely uncertain. Hence, a deep insight into the response and feedback of terrestrial C and N cycling to elevated CO2 would be of great importance for quantifying the terrestrial and soil C sequestration potential under global change scenarios. This paper fully reviewed the mechanisms and controls on terrestrial C and N cycling response to elevated CO2. We found that elevated CO2 significantly increased the accumulation of plant biomass C, production and release of soil GHG, and soil C and N pools, while decreased the supply of soil labile N. Klevated CO2 decreased upland uptake of CH4. Klevated CO2-enhanced emission source of soil GHG to the atmosphere completely offset the soil C sink capacity, and also more than half of the terrestrial C sequestration potent ial, which showed a declining trend with CO2 enrichment levels. Meanwhile, we proposed the potential h iotie and abiotie faetors influencing soil GHG exchanges between terrestrial ecosystems and atmosphere under enriched C02. This review would provide an important theoretical basis for estimation of terrestrial carbor i balance. [ABSTRACT FROM AUTHOR]
