Natural gas is lauded as a cleaner-burning fuel than either coal or oil, but getting the fuel out of the ground can be a dirty process, especially given the widespread adoption of the technology known as hydraulic fracturing (" fracking "). Concerns about toxic air emissions from previously unregulated fracking sites led to the U.S. Environmental Protection Agency announcement on 18 April 2012 ...

For political, jurisdictional and technical reasons, environmental regulation of industrial pollution is often incomplete: regulations apply to only a subset of facilities contributing to a pollution problem. Policymakers are increasingly concerned about the emissions leakage that may occur if unregulated production can be easily substituted for production at regulated firms. This paper analyze...

This scientific study is focused on the analysis of an influence experimental diesel fuel mixtures containing various portions biocomponent unregulated gaseous emissions generated by a motor vehicle, which equipped with engine utilizing direct injection system “common rail”. The main reason for choice this type was its wide usage in current vehicles. were created as mixture standard low-sulfur ...

Emissions from passenger ferries operating in urban harbors may contribute significantly to emissions inventories and commuter exposure to air pollution. In particular, ferries are problematic because of high emissions of oxides of nitrogen (NOx) and particulate matter (PM) from primarily unregulated diesel engines. This paper explores technical solutions to reduce pollution from passenger ferr...

Environmental regulation is increasingly judged on its ability to stimulate innovation. While prior studies focus primarily on the direct effect on innovation by regulated firms, this paper examines the importance of indirectly induced innovation by both regulated and unregulated firms. Two channels for indirect effects are considered: passthrough of regulation-imposed costs into output prices ...

Unilateral carbon policies are inefficient due to the fact that they generally mean that abatement takes place in high-cost countries and because they are subject to carbon leakage. In this paper, we ask whether the use of carbon tariffs — tariffs on the carbon embodied in imported goods — might lower the cost of achieving a given reduction in world emissions. Specifically, we explore the role ...

In recent years more and more focus has been placed on the environmental aspects of ships, because of the great attention to exhaust gas emissions from ships including CO2, a leading contributor to Green House Gasses (GHG) emissions, due to their negative effect on global warming. Maritime transport has clear environmental advantages: it expends relatively little energy and its infrastructure r...
