At the present day, requirements to the quality of marine fuel and to the volumes of air pollutant emissions become stricter for shipping in the Arctic Region. This article states that one of the most important ways to follow the emission limits is switching the ice-rated vessels to liquefied natural gas (LNG) as fuel. As compared with oil fuels, LNG has the superior calorific value and the best physical characteristic. It is noted that Russia has a number of opportunities to apply LNG both for supply of water and...

Opinions on the potential uses of risk analysis and environmental impact assessment (EIA) are different. Although many experts, researchers, practitioners and policy-makers agree that risk analysis is a valuable tool to inform decisions, they disagree about the extent to which risk estimates may be biased and should be allowed to influence public policies to protect health and the environment and to be used within the EIA process. The quality and value of any risk analysis depends on the adequacy of the data and t...
