The economic growth in Vietnam has not been without cost as the natural environment - forests, biodiversity and coastal zones-came under additional pressure. To address the situation with the aim of proactive prevention, the Prime Minister issued the Directive No. 25/CT-TTg, dated 31/8/2016, on some urgent missions and solutions to protect environment. In Article 3, item (c) of the Directive, the Prime Minister requested MPI “to study and regulate a specific level of environmental expenditures in total amount of investments for investment projects”.

This is a pioneer study investigating the relationship between environmental compliance and TFP convergence for SMEs. It examines the impacts of environmental compliance, and its combination with innovation, on TFP convergence of manufacturing SMEs. We applied the dynamic panel regression method to estimate stochastic TFP. We find evidence of a β-convergence but a σ-divergence. Impacts of environmental practices of firms—pollution abatement and control expenditure, and environmental treatment—are only significant through their interaction with innovation.

Effluent discharges from municipal, industrial, and agricultural activities constitute major sources of pollution on land and water bodies. During the 1990s, large -scale application of Constructed Wetlands (CWs) as a remediation option drew much attention globally from the public and green groups alike. The most common application of CWs is for flow management in river system and little is documented on using CWs for treating polluted river water.

Only a few studies consider the increased ventilation rate associated with active modes. One study [22] showed that the minute ventilation rate (product of the breathing rate and the volume of air per breath) of cyclists was on average twice that of car commuters (an increase from 12 L min-1 to 24 L min-1 ) and two studies [21, 23] suggest 31 L min-1 , and 40-60 L min-1 for cyclists, respectively. No studies could be found specifically in relation to the exposure of commuters who run to work, though one would expect these to be comparable or higher than those of...

We begin with two fairly obvious points. First, not surprisingly, for both of the maquiladoras, the health damages (whether measured in number of cases or in dollars) from uncontrolled emissions are considerably higher than for controlled emissions. For the iron foundry, damages are approximately 17 times as high for uncontrolled emissions as for controlled emissions. For the chemical plant, they are approximately 50 times as high. Thus, it bears emphasis that the magnitude of the health damages from maquiladora emissions depends critically on the level of emissions abatement.

Unfortunately, data on the installation and use of pollution control equipment at our two sample maquiladora plants is limited. While the two plants claim to use emissions abatement devices, regulatory inspection and monitoring data is not available, and there is no easy way of verifying these claims. To account for this issue, we present estimates of health damages given: (i) emissions that would result if the plants used no pollution control devices whatsoever, and (ii) emissions that would result if they used all of the pollution control equipment that is standard in U.S.

It requires detailed data on plant characteristics, including the type of products or output, the scale of production, the type of production technology, and the type of abatement equipment used. In the summer of 2001, we interviewed managers and engineers of the plants on our list (both in person and by telephone) in an attempt to obtain these data. Only two of the industrial facilities on our list—the gray iron foundry and the chemical plant described above—provided all of the information needed to estimate emissions.

The available data does, however, suggest that present PM10 values exceed the recommended limit values in the majority of Member States. In future projections, planned actions should be taken into consideration. These include the SOx and NOx Protocols within UNECE and the Auto-Oil programme. Abatement policies for other pollutants will also have an impact.

Accessibility is a key ingredient of well-being and prosperity in contemporary societies. The ability of individuals, families, entrepreneurs and firms to exchange goods and services, to be where activities are being carried out, and to interact with people on a regular basis is crucial not only to economic life but also to the quality of life. With the growth of economic and social networks over the course of the past two centuries, and t he spatial dispersion of activities, transportation has become a vital part of the systems providing access to those activities.

Technical approaches seek to reduce the emissions produced by road vehicles using the transport system by intervening with the vehicles being used and the fuels they are burning. By definition, these approaches address per unit emissions rather than the amount of activity causing the emissions. An exclusively technological approach may be insufficient to address the growth in emissions, for a number of reasons. First, growt h in activity continuously puts pressure on technology gains.

Starting from the in situ quality of waterbodies themselves and working backwards to address threats to quality sounds like simple common sense. It is, but it is not how one would describe the current regulatory system. The focus of the current system is on specific numeric discharge limits applied to a precisely defined universe of pollution sources. The quality of surface waters themselves is a binding regulatory issue only if quality is adequately monitored and if point sources are found to be the source of the problem. Effluent taxes could play an important role in...

Economists have long advocated pollution taxes as a policy to improve water quality. One of the reasons water effluent taxes are embraced by economists interested in market-based policies is that sources of water pollution are varied and difficult to assess individually in terms of control costs. In principle, taxes overcome this problem. With a price—the tax—applied to pollution emissions, firms compare the price to their costs of emissions control. If the price is higher than control costs, they reduce emissions rather than pay the tax.

Water is crucial for the economy. Virtually every industry from agriculture, electric power and industrial manufacturing to beverage, apparel, and tourism relies on it to grow and ultimately sustain their business. Yet water is becoming scarcer globally and every indication is that it will become even more so in the future. Decreasing availability, declining quality, and growing demand for water are creating significant challenges to businesses and investors who have traditionally taken clean, reliable and inexpensive water for granted.

Analysis and abatement of air pollution involve a variety of technical disciplines. Formation of the most prevalent pollutants occurs during the combustion process, a tightly coupled system involving fluid flow, mass and energy transport, and chemical kinetics. Its complexity is exemplified by the fact that, in many respects, the simplest hydrocarbon combustion, the methane-oxygen flame, has been quantitatively modeled only within the last several years.

A Abatement: Reducing the degree or intensity of, or eliminating, pollution. Abatement Debris: Waste from remediation activities. Absorbed Dose: In exposure assessment, the amount of a substance that penetrates an exposed organism's absorption barriers (e.g.,, skin, lung tissue, gastrointestinal tract) through physical or biological processes. The term is synonymous with internal dose. Absorption Barrier: Any of the exchange sites of the body that permit uptake of various substances at different rates (e.g., skin, lung tissue, and gastrointestinal-tract wall).

The contents of this book are based loosely on presentations at a special symposium, “Application of Interface Science to Environmental Pollution Control,” held as part of the ACS National Meeting in Chicago, August 26–30, 2001. This symposium offered an opportunity for researchers from a range of disciplines to discuss the role of interface science in environmental remediation. The development of an archival book based on this meeting is a timely contribution to a burgeoning area of research that is now attracting the attention of a diverse research community.
