Oil pollution in the North Sea: the impact of governance measures on oil pollution over several decades

Oil pollution entering the marine environment has been an issue of concern for many decades. It can come from riverine or land-based sources, accidental and intentional discharges from ships, or as a by-product of offshore oil extraction. Growing awareness of the impact of oil pollution on the marine environment has led, since the late 1960s, to the introduction of measures to reduce or eliminate pollution from shipping and the offshore oil industry. A framework for environmental protection of the North Sea has developed over many decades through international agreements, regional cooperation, and national measures, while education has also played an important role with modern-day sailors being given due training to understand that dumping waste at sea is illegal in many areas, and is harmful to the marine environment. This paper presents data on trends in pollution from ships and oil installations. While significant reductions in oil pollution have been identified over more than two decades, there remain some areas where action is needed to reduce inputs still further, especially from oil and gas platforms

Evaluating the institutional sustainability of an urban water utility: A conceptual framework and research directions

This article was published in the journal, Utilities Policy [© Elsevier]. The definitive version is available at: http://dx.doi.org/10.1016/j.jup.2013.08.001Institutional sustainability (IS) is critical to translating infrastructure investments into actual service delivery. This paper examines IS for urban water utilities, and how its progress could be tracked. Common conceptualisations of IS in extant literature were found inadequate from an evaluation stand point. We conceptualize IS as a capacity rather than a financial issue, and, consistent with a process-based approach, we propose a new evaluation tool e the water utility maturity (WUM) model e which is flexible and considers different levels of IS. The WUM model, which requires further validation/verification, was piloted in two water utilities in South Asia with positive feedback

The carbon impact of short-haul tourism: A case study of UK travel to Southern France using life cycle analysis

Tourism holds a significant share in the global carbon footprint. Transportation to the destination is recognized as the primary contributor, although its contribution can be less dominant in the context of short-haul travel. Previous studies do not provide a critical comparative analysis of how changes in travel behaviour, notably modal shift, affect the total carbon impacts from short-haul holidays; nor do they explore the relative contribution of the specific elements of the holiday product or account for global variations when measuring those contributions. This paper presents a carbon impact assessment case study of short-haul tourism to Southern France by British tourists. It applies an advanced, Life Cycle Assessment-based, method of evaluation, the hybrid DEFRA-LCA (Ecoinvent) approach, which is capable of appraising both the direct and the embodied 'indirect' greenhouse gas emissions. The principal finding supports the traditional view that transportation generates the largest carbon footprint and that the most significant carbon savings can be achieved by switching from air and car-based travel to train and coach. However, the study also indicates that if tourists stay at the destination longer, and travel to the destination by train or coach, the destination-based elements of the holiday can make a large carbon contribution and even outweigh the share of the transit element. The Life Cycle Assessment also shows that the 'indirect' greenhouse gas emissions from tourism in Southern France are significant, thus emphasizing the importance of their incorporation into future carbon impact appraisals. © 2013 Elsevier Ltd.
