Previous studies on the effectiveness of improving sustainable development have acknowledged the importance of domestic research and development (R&D) activities. However, these studies remain general and ambiguous because they assume that all R&D activities are related to energy-saving and sustainable development. The corresponding empirical evidence is scabrous and ambiguous. In this paper, we focus on the effect of green innovation R&D activities on SO2 emission which is an important greenhouse gas affect global climate change and eco-civilization. Considering that there is heterogeneity exists in the innovation activities, the R&D activities are divided into three performers with two purposes. The empirical results based on a Chinese inter-provincial dataset of 2000-2016 suggest that the green innovation R&D activities are crucial for the reduction of the SO2 emission. However, the innovation R&D activities of different purposes and performers show statistically differentiated effects on SO2 emission. The major positive effect of green innovation R&D activities on SO2 emissions reduction is mainly from enterprises and utility-type of R&D activities. A further study based on the panel threshold also indicates that effects of green innovation R&D activities on SO2 emissions are nonlinear, depending on the technology absorptive ability.

Abstract. Simulations of present and future average regional ozone and PM2.5 concentrations over the United States were performed to investigate the potential impacts of global climate change and emissions on regional air quality using CMAQ. Various emissions and climate conditions with different biogenic emissions and domain resolutions were implemented to study the sensitivity of future air quality trends from the impacts of changing biogenic emissions. A comparison of GEOS-Chem and CMAQ was performed to investigate the effect of downscaling on the prediction of future air quality trends. For ozone, the impacts of global climate change are relatively smaller when compared to the impacts of anticipated future emissions reduction, except for the Northeast area, where increasing biogenic emissions due to climate change have stronger positive effects (increases) to the regional ozone air quality. The combination effect from both climate change and emission reductions leads to approximately a 10% or 5 ppbv decrease of the maximum daily average eight-hour ozone (MDA8) over the Eastern United States. For PM2.5, the impacts of global climate change have shown insignificant effect, where as the impacts of anticipated future emissions reduction account for the majority of overall PM2.5 reductions. The annual average 24-h PM2.5 of the future-year condition was found to be about 40% lower than the one from the present-year condition, of which 60% of its overall reductions are contributed to by the decrease of SO4 and NO3 particulate matters. Changing the biogenic emissions model increases the MDA8 ozone by about 5–10% or 3–5 ppbv in the Northeast area. Conversely, it reduces the annual average PM2.5 by 5% or 1.0 μg/m3 in the Southeast region.

This paper evaluates the real effects of pollution charges reform on [Formula: see text] emissions at the city level. Using the establishment of Comprehensive Work Plan for Energy Conservation and Emission Reduction (The Plan) in China as a quasi-natural experiment, our difference-in-differences estimation shows that: (1) increasing pollution charges has a significant and positive effect on controlling industrial waste [Formula: see text], and this relationship is robust to different specifications and alternative measures; (2) [Formula: see text] emissions can be reduced to achieve reduction targets by forcing companies to strengthen the degree of process production controls and end-of-pipe treatment; (3) eastern and western cities have a better pollution control effect than the other regions, and large cities have better emission reduction effects than smaller cities. Overall, this paper sorts out the evolution of China’s pollution charge policy, and reveals the mechanisms behind the real effects of pollution charges reform on [Formula: see text] emissions, thus providing timely implications for policymakers concerned with environmental protection.

Impacts Of Climate Change

Abstract Ho Chi Minh City (HCMC), the largest city in Vietnam, is steadily growing, certainly towards a mega city in the near future. Like other mega cities at the boom stage, it has to face with serious environmental matters insolvable for many years. The situation may be worse under the effects of global climate change, geological subsidence due to non-standard construction and sea level rise. The situation of HCMC can be damaged or even broken by resonant effects of unsolved environmental matters and latent impacts of climate change. This article shows the challenges to the urban sustainable development under the duo effect of urban environmental matters and climate change in Ho Chi Minh City. Opportunities and strategic directions to overcome the challenges are also analyzed and recommended.

Recognizing the pressing global problem of climate change, the IPCC was formed in 1988 as an apex source to holistically address the issue. It strives to critically congregate best scientific, technical and socio-economic data on global climate change to produce various papers and reports which become standard works of reference (UNEP, 2004). IPCC has contributed extensively to unleash the mitigation potential from the perspective of agriculture, correlating it with climate change policy, environmental quality and ultimately, sustainable development (Working group II, 2007). Agriculture lands form 40- 50% of the earth’s land surface and contribute to 10-12% of the Greenhouse gas (GHG) emissions. In this sector, by improved crop, soil, water, livestock and water management, the mitigation of climate change can be approached in a cost-effective way than other sectors. Hence this paper dwells into the significant role of IPCC to progress towards sustainable development in agriculture sector. It would discuss about how agriculture management activities would decrease GHG emissions and increase carbon sequestration (Technical group V, 2002). In the warming world, precipitation is skewed, sea level is rising, glaciers are melting, acidic levels in oceans are rising and dissolved oxygen in sea water is declining (IPCC, 2014). Hence major river floods are likely, which is a threat to the food production. This paper would highlight the need to limit effects of climate change to achieve sustainable development as the focus, and would further discuss social equity and poverty eradication. It would explore adaptation and mitigation methods to enumerate short and long-term goals to combat climate change from reinvented livestock and crop systems, beneficial land use changes, improved fertilizers and advanced technological perspectives (IPCC, 1990). It would enforce the learnings from IPCC’s contributions enumerating how agriculture must have a high synergy with sustainable development to address global climate change.

In December 2015, 196 countries will meet in Paris to reach a new global climate change agreement. This case looks at the climate negotiation process from the eyes of India's environment minister Mr Prakash Javadekar. In India's context, the energy sector has a big role to play in emission reduction as it is the largest emitter of the GHGs. When compared to US and China, India's per-capita emissions are miniscule but they are expected to rise substantially as the GoI is investing heavily in the infrastructure sector which has a substantial carbon footprint. The case discusses the mandatory emission cuts that India will announce considering the fulfillment of sustainable development goals. The case also points out, the government's promise of providing 24*7 electricity by 2019 which it feels can be an impediment in setting an aggressive emission cut target. The case questions if changes in the portfolio mix can be a part of the solution.

Well before island nations began to consider rising ocean levels, a feature of global climate change, they have been concerned with the allocation of water resources. The purpose of this chapter is to revisit the efforts of Zanzibar's academic, as well as private and public institutions, as they promote environmentally responsible entrepreneurial projects, while advancing women's economic empowerment. Analysis will examine the history of seaweed production and consider how Zanzibar's seaweed farmers have recently responded to the dislocations associated with global climate change. This discussion will also consider to what extent Zanzibari seaweed production reflects the norms enshrined in the United Nation's Rio + 20 platform, and the language of the UN's 2030 sustainable development goals.
