Abstract China repond quickly to explosure of Covid-19. This paper aims to evaluate the impact of lockdown on 5 major airborne pollutant in Shanghai. Chongming, Xuhui and Jinshan areas of Shanghai were studied and compared. Overall, the Covid-19 lockdown has changed pollutant concentration in both long and short terms. All the five concentrations except for O3 increased. SO2 had significant correlations with all other pollutants. Ozone on eath surface are mainly from green plants and can be reduced by both NO2 and some organic matters. PM2.5 nd PM10 are more external than local procuced. NO2, SO2 and PM matters sharply reduced in Jinshan and Xuhui during dued to the limited usage of fossil fuel. All these activies could both meet humen’s neccesary needs and keep a better air quality. Proper and systematic measures should be taken to in keeping better air quality and economic growth in the whole world.

Abstract. Vehicles burning fossil fuel emit a number of substances that change the composition and chemistry of the atmosphere, and contribute to global air and water pollution and climate change. For example, nitrogen oxides and volatile organic compounds (VOCs) emitted as byproducts of fossil fuel combustion are key precursors to ground-level ozone and aerosol formation. In addition, on-road vehicles are major CO2 emitters. In order to tackle these problems, molecular hydrogen (H2) has been proposed as an energy carrier to substitute for fossil fuel in the future. However, before implementing any such strategy it is crucial to evaluate its potential impacts on air quality and climate. Here we evaluate the impact of a future (2050) H2-based road transportation sector on tropospheric chemistry and air quality for several possible growth and technology adoption scenarios. The growth scenarios are based on the high and low emissions Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios, A1FI and B1, respectively. The technological adoption scenarios include H2 fuel cell and H2 internal combustion engine options. The impacts are evaluated with the Community Atmospheric Model Chemistry global chemistry transport model (CAM-Chem). Higher resolution simulations focusing on the contiguous United States are also carried out with the Community Multiscale Air Quality Modeling System (CMAQ) regional chemistry transport model. For all scenarios future air quality improves with the adoption of a H2-based road transportation sector, however, the magnitude and type of improvement depend on the scenario. Model results show that with the adoption of H2 fuel cells decreases tropospheric burdens of ozone (7%), CO (14%), NOx (16%), soot (17%), sulfate aerosol (4%), and ammonium nitrate aerosol (12%) in the A1FI scenario, and decreases those of ozone (5%), CO (4%), NOx (11%), soot (7%), sulfate aerosol (4%), and ammonium nitrate aerosol (9 %) in the B1 scenario. The adoption of H2 internal combustion engines decreases tropospheric burdens of ozone (1%), CO (18%), soot (17%), and sulfate aerosol (3%) in the A1FI scenario, and decreases those of ozone (1%), CO (7%), soot (7%), and sulfate aerosol (3%) in the B1 scenario. In the future, people residing in the contiguous United States are expected to experience significantly fewer days of elevated levels of pollution if a H2 fuel cell road transportation sector is adopted. Health benefits of transitioning to a H2 economy for citizens in developing nations, like China and India, will be much more dramatic particularly in megacities with severe air-quality problems that are exacerbating.

Background The progress of green credit in China is accelerating, but its development is uneven and insufficient in different regions. And whether the issuance of green credit can effectively promote the improvement of the environment and economy is not well understood. Objective Previous research has found that green credit promotes economic growth through improvement of the industrial structure and green technological innovation. However, these studies have not considered the positive externality of environmental improvement even though environmental improvement and economic growth are requirements of the sustainable development concept. Methods We use the chain-mediated model to estimate the impact of green credit issuance on the economic growth of different provinces since the large-scale implementation of green credit in China with data from 2008 to 2016. Results and conclusion This paper shows that the issuance of green credit can improve labor supply rather than labor productivity through the improvement of air quality to achieve regional economic growth. Such a chain-mediated path is different from the economic growth caused by industrial structural adjustment and green technology innovation. At the national level, every 1% increase in green credit issuance relative to industrial loans will increase the per capita gross domestic product (GDP) by approximately 4.6 yuan, or 0.012%, through air quality and labor supply, accounting for 2.875% of the total effect. Heterogeneity analysis indicates that due to regional industrial structure differences and diminishing marginal effects, the impact of green credit is stronger in the western region than in the eastern and central regions. For every 1% increase in the proportion of green credit issuance relative to industrial loans, the per capita GDP growth achieved through the chain-mediated path is approximately 30.17 yuan in the western region, approximately 6.6 times greater than that at the national level. Within a 95% confidence interval of 5000 bootstrap samples, this path is found to be true, and the chain-mediated effect accounts for approximately 12.96% of the total indirect effect. Limitations The limitation of this paper is the measurement of green credit. Although green credit has a large volume, it remains underdeveloped, and there is a lack of perfect indicators. Most existing studies have adopted only alternative or reverse indicators to measure the issuance of green credit. For example, this paper takes the interest expenditure of six high-energy-consuming enterprises as the reverse indicator, which may to a certain extent lead to the overestimation of the issuance of green credit and its impact on the environment and economy. Future research can accurately explore the performance of green credit on the basis of its mature development.

The Impact

This study investigates the impact of energy subsidy, energy consumption, urbanization, economic growth, foreign direct investment, and trade openness on carbon dioxide emission and other greenhouse gases in Nigeria. Based on the method of cointegration and Autoregressive Distributed Lag (ARDL), the study utilized data from 1970 to 2018 for the analysis. The study found fossil fuel consumption, economic growth, trade openness and PMS Price (a proxy for subsidy) as significantly increasing emission (Carbon dioxide) in Nigeria. The implication is that as that as the prices of PMS goes up (due to subsidy reduction), more of fuel is consumed. Our analysis demonstrated that PMS is price inelastic in Nigeria. In addition, subsidy or its removal will have no impact on carbon dioxide emission and other greenhouse gas emission in Nigeria. The study recommends the development of cleaner, renewable fuels and the development of abatement technology so as to mitigate the environmental impacts of growth. In addition, since the reduction in subsidy has no deterrent impact on fossil fuel consumption in Nigeria, then the recent removal of fossil fuel subsidy in Nigeria is a welcome development at least for the environment.

This paper assesses the impact of pollution on worker productivity by relating exogenous daily variations in ozone with productivity of agricultural workers as recorded under piece rate contracts. We find robust evidence that ozone levels well below federal air quality standards have a significant impact on productivity. These results suggest that, in contrast to common characterizations of environmental protection as a tax on producers, environmental protection can also be viewed as an investment in human capital, and thus a tool for promoting economic growth.

No2 Pollution

Abstract. The Indian economy has grown significantly during the past decades. Satellite-based remote sensing enables atmospheric pollution to be observed globally, in remote regions, and in regions where the infrastructure for air quality monitoring is limited. Here, we investigate the temporal evolution of tropospheric nitrogen dioxide (NO2) since the early 2000s, and correlate NO2 abundances with indicators of economic development, notably gross state domestic product and electricity generation capacity, for all 35 Indian states and union territories. From 2003–2012, NO2 pollution and economic growth are strongly correlated, leading to annual increases of up to 4.4 %. This increase is strongest in states in East India having heavy industry. In 2012, the amount of tropospheric NO2 reached a maximum; since then, tropospheric NO2 pollution has stabilized or is even declining. While the Indian economy continues to grow, this decline in observed NO2 values may be a result of a slow-down in Indian economic growth, combined with the implementation of cleaner technology. Additionally, we identify regional pollution sources such as individual steel smelters and the cement industry, which are severely degrading air quality. In Tamil Nadu, economic growth has not led to increasing NO2 columns, which we attribute to the investment in the development of renewable energy sources during the 2000s.

The Impact

The current examination ascertains the impact of foreign direct investment, urbanization, economic growth, fossil fuel consumption  on carbon emissions in eleven rising Asian economies. Panel data has been scrutinized from 1990 to 2018, and (ARDL)/PMG model is executed. The outcomes of the model exemplify that in these growing Asian economies, the triumph to cuitivate economic growth, foreign direct investment, urbanization and fossil fuels are bestowing CO2 emissions and deteriorating the environmental circumstances at the regional level. Moreover, the conclusions emphasis that foreign direct investment is a source of environmental humiliation and increases carbon emissions at the regional level. Furthermore, outcomes of the investigate also confirmes the existence of (EKC) in these eleven emerging Asian economies. The study also suggest that by lessening the consumption of fossil fuel energy and encouragement of an environmental responsive economic growth policy will be suitable for the affluence in these emerging developing Asian economies and also the rest of world.
