摘要:

Climate mitigation has become a global issue and most countries have promised their greenhouse gas reduction target. However, after Trump took office as president of the United States (US), the US withdrew from the Paris Agreement. As the biggest economy, this would have impacts on the emission space of other countries. This paper, by using the integrated model of energy, environment and economy/computable general equilibrium (IMED/CGE) model, assesses the impacts of the US withdrawal from Paris Agreement on China, India in terms of carbon emission space and mitigation cost under Nationally Determined Contributions (NDCs) and 2°C scenarios due to changed emission pathway of the US. The results show that, under the condition of constant global cumulative carbon emissions and fixed burden sharing scheme among the countries, the failure of the US to honor its NDC commitment will increase its carbon emission space and decrease its mitigation cost. However, the carbon emission space of other regions, including China and India, will be reduced and their mitigation costs will be raised. In 2030, under the 2°C target, the carbon price will increase by US$14.3 to US$45.3/t in China and by US$10.7 to US$33.9/t in India. In addition, China and India will incur additional GDP loss. Under the 2°C target, the GDP loss of China would increase by US$23.3 to US$72.6 billion (equivalent to US$17.4 to US$54.2/capita), and that of India would rise by US$14.2 to US$43.1 billion (equivalent to US$9.3 to US$28.2/capita).

摘要:

Following the Paris Agreement, green and low-carbon development has entered into a new stage. China’s international responsibility to combat climate change is consistent with the inherent sustainable development needs of the country. In this paper, the reasonability of China’s Intended Nationally Determined Contributions (INDC) is examined and the fact that low-carbon development can lead to modernization is demonstrated based on data analysis of energy economics from developed countries. Considering the fact that such an energy revolution forms the basis for China’s low-carbon transition, a roadmap of the China’s energy utilization is presented. Based on research results from the Chinese Academy of Engineering, the three historical stages of China’s energy structure reform are analyzed. Promoting a low-carbon transition through an energy revolution is a long-term and arduous process that requires a genuine transformation of development outlook and patterns. By empirically analyzing situations at home and abroad, a conclusion is made that economic development and a low-carbon transition can be achieved simultaneously; specifically, low-carbon development fosters new points of economic growth and gives rise to different development paths.

How diplomacy saved the COP21 Paris Climate Conference, but now, can we save ourselves?

摘要:

To solve a problem, three things are necessary: awareness, means, and will. The 2015 COP21 Paris accord was a masterful, perhaps even world-saving, diplomatic advance toward making the world aware of climate change. Some of that success may have been because publications from the IPCC and the National Academy of Science were made available, on line, as prepublication offerings, in order to be widely viewed before the Paris Climate Conference. This provided diplomats and negotiators with the latest information about climate change, its nearness in time, its consequences, and how well current mitigation technologies can succeed. Whatever the reasons, the Paris Climate Conference, was a success. Leaders of 195 nations agreed that climate change is a real and present danger to life as is known to all. This important understanding was accomplished despite the presentation of well established scientific facts which, without very diplomatic handling, could easily have evoked overwhelming political opposition to an agreement and thus another COP failure. In this paper, the fact that how some scientific truths, written specifically to be overlooked, were presented in order to prepare COP21 participants for the conference is explained. Besides, the effectiveness and efficiency of currently favored mitigation policies, the extent of ongoing progress to better ones, and finally, how a new appreciation of climate change consequences can strengthen the will of nation states and industries to work toward solutions are evaluated.

摘要:

Global response to climate change has entered the phase of full implementation of the Paris Agreement. To control the global temperature rise below 2°C, all countries must make more efforts to reduce emission. China has combined its goal of emission reduction for combating climate change with its domestic sustainable development strategy to promote energy revolution and the transition of economic development to low-carbon patterns. Through reinforcing the commitment and action before 2020, the CO2 intensity of GDP can decrease by more than 50% by 2020 compared with that of 2005, and the external commitment target of a 40%–45% decrease can be over fulfilled. Currently, under the new economic normal, China further strengthens the policy measure, vigorously saves energy, enhances energy use efficiency and the economic output benefit, and simultaneously develops new and renewable energy and accelerates energy structural decarbonization, so that the annual decrease rate of the CO2 intensity of GDP keeps a high level of more than 4% and remains increasing. Thus, the decrease rate of the CO2 intensity of GDP will exceed the GDP growth rate, and then CO2 emission will peak around 2030. This will promote the fundamental turning of economic development mode, and lay a foundation for the establishment of a sustainable energy system with near-zero emissions and with new and renewable energy as the main body in the second half of this century. China implements the concept of green low-carbon development and accelerates the low carbon transition of energy and economy to achieve win-win results in economic growth and CO2 emission mitigation, and these policies and actions will also provide experiences for many other developing countries. On the other hand, China will continue to play a positive and constructive leading role in the implementation of the Paris Agreement internationally, and promote the construction of new mechanisms of win-win cooperation, fairness and justice and common development for global climate governance. Moreover, China will make an effort to build a community of common destiny for mankind, promote pragmatic cooperation among countries, especially among developing countries, and take combating climate change as a new development opportunity for jointly moving toward climate-friendly low-carbon economic development path.

摘要: Recently, China, Japan, and the Republic of Korea (Korea) are conducting a government-commissioned feasibility study on the Free Trade Agreement among the three countries (CJKFTA) to form a regional free trade zone in East Asia. Considering that freer trade can cause unexpected impact on domestic environment, there is a need to evaluate the environmental impact of such a trade policy. This move should be made to help negotiators understand and pay more attention to environmental issues during CJKFTA negotiations, and to help lobby with the government to carry out appropriate policy instruments for adaptation or mitigation. Following the Chain Reaction Assessment Method that integrates and links the elements of trade, production, and environment, the present research aims to quantitatively assess CJKFTA’s possible impact on China’s environment. This is done by estimating the variations of China’s major conventional pollutants and greenhouse gases (GHGs) emission in two policy scenarios to represent CJKFTA’s scale and composition effects on China’s environment. Estimating the variations is based on a static Computable General Equilibrium model, working with Global Trade Analysis Project (GTAP) 7 database and China’s energy-environment statistics. Based on these assessments, CJKFTA is predicted to lead to notable environmental impact, including increased emissions of agricultural total nitrogen, agricultural total phosphorus, chemical oxygen demand, and GHGs. On the other hand, decreased emissions of industrial SO and dust are also expected to happen. Suitable policies need to be made to combat negative effects and amplify positive ones, while aiming at a more sustainable regional freer trade system.

摘要:

《巴黎协定》提出把全球平均地表气温升幅控制在较工业化前水平的2°C 之内,并努力限制在1.5°C之内。这是第一个使“全球2°C 温升目标”具备法律效力的国际条约,《联合国气候变化框架公约》第二条关于最终目标的定性表述,至此演进为《巴黎协定》第二条包含具体数值的全球温升目标。从政府间气候变化专门委员会(IPCC) 第二次评估开始,为《联合国气候变化框架公约》谈判提供有助于确定定量化长期目标的科学信息就成为后续历次评估的重要任务,但由于涉及非科学评估范畴的价值判断,IPCC 从未从科学上认定全球升温到何种程度是不可接受的。应对气候变化长期目标的确定经历了长期的过程,“全球2°C 温升目标”是建立在科学评估基础上的一个政治共识。本文从“全球2°C 温升目标”的由来、IPCC 围绕《联合国气候变化框架公约》第二条开展的系列评估,以及不同政治层面对温升目标的推动等几个方面,分析了国际应对气候变化长期目标的演进过程,及其对未来科学评估、谈判进程和全球低碳发展走向的影响。

《化学科学与工程前沿(英文)》 2008年 第2卷 第2期   页码 209-213 doi: 10.1007/s11705-008-0039-7

摘要: By considering the features of fluidized-bed reactors and the kinetic mechanism of biomass gasification, a steady-state, isothermal, one-dimensional and two-phase mathematical model of biomass gasification kinetics in bubbling fluidized beds was developed. The model assumes the existence of two phases – a bubble and an emulsion phase – with chemical reactions occurring in both phases. The axial gas dispersion in the two phases is accounted for and the pyrolysis of biomass is taken to be instantaneous. The char and gas species CO, CO, H, HO, CH and 8 chemical reactions are included in the model. The mathematical model belongs to a typical boundary value problem of ordinary differential equations and its solution is obtained by a Matlab program. Utilizing wood powder as the feedstock, the calculated data show satisfactory agreement with experimental results and proves the effectiveness and reliability of the model.

Gas-solids separation model of a novel FCC riser terminator device: super short quick separator (SSQS)

LU Chunxi, LI Ruxin, SHI Mingxian, LIU Xiancheng

《化学科学与工程前沿(英文)》 2008年 第2卷 第4期   页码 462-467 doi: 10.1007/s11705-008-0068-2

摘要: The gas flow field and the separation efficiency of a novel fluid catalytic cracking (FCC) riser terminal device, named as Super Short Quick Separator (SSQS), were studied. On the basis of above investigations, a section-lateral-mixing separation model was proposed, which included both the effect of inertia and structure of gas outlet on particles capture. After final modification, the results predicted with this model could be in good agreement with the cold experimental data. According to this model, the separation efficiency of SSQS is mainly influenced by the difference between the arc radius and the center pipe radius as well as the magnitude of particle tangential velocity.

《结构与土木工程前沿(英文)》 2015年 第9卷 第4期   页码 359-382 doi: 10.1007/s11709-015-0304-z

摘要: This paper deals with the fatigue crack growth simulations of three-dimensional linear elastic cracks by XFEM under cyclic thermal load. Both temperature and displacement approximations are extrinsically enriched by Heaviside and crack front enrichment functions. Crack growth is modelled by successive linear extensions, and the end points of these linear extensions are joined by cubic spline segments to obtain a modified crack front. Different crack geometries such as planer, non-planer and arbitrary spline shape cracks are simulated under thermal shock, adiabatic and isothermal loads to reveal the sturdiness and versatility of the XFEM approach.

摘要:

The prevalence of tuberculosis infection among adolescents born after terminating the Bacillus Calmette–Guérin (BCG) booster vaccination in China was estimated using tuberculin skin testing (TST) and QuantiFERON-TB Gold assay (QFT) to investigate the influence of neonatal BCG vaccination on the performance of TST. Data analysis was conducted for 2831 eligible participants aged 5–15 years from the baseline survey of a population-based multi-center prospective study. The prevalence rates of TST (induration≥10 mm) and QFT positivity were 9.3% (264/2827) and 2.5% (71/2831), respectively. The rate of QFT indeterminate result was 2.2% (62/2831). The overall agreement between TST and QFT was low (concordance= 88.0%; κ coefficient= 0.125). Only TST was positively associated with BCG vaccination with an adjusted odds ratio of 1.71 [95% confidence interval, 1.26–2.31]. A history of close contact with patients of active TB was significantly associated with positivity for TST and QFT. Our results suggested that BCG neonatal vaccination still affects TST performance, and a two-step approach might be considered for TB infection testing among adolescents in China.
