    AbstractCO2 emissions from maritime transport represent 3.3% of the world's total CO2 emissions and are forecast to increase by 150%–250% by 2050, due to increased freight volumes (Second IMO GHG study, 2009). Fulfilling anticipated climate requirements (IPCC, 2007) could require the sector to reduce emissions per freight unit by a factor of five or six. The International Maritime Organization (IMO) is currently debating technical, operational and market-based measures for reducing greenhouse gas emissions from shipping. This paper also investigates the effects of economies of scale on the direct emissions and costs of maritime transport. We compared emissions from the current fleet (2007), with what can be achieved by increasing average vessel size. The comparison is based on the 2007 levels of trade and predictions for 2050. The results show that emissions can be reduced by up to 30% at a negative abatement cost per ton of CO2 by replacing the existing fleet with larger vessels. Replacing the whole fleet might take as long as 25 years, so the reduction in emissions will be achieved gradually as the current fleet is renewed

    Negotiating their right to play: Asian-specific cricket teams and leagues in the UK and Norway

    The cultural significance of ‘ethnic-specific’ cricket teams and leagues has received limited scholarly attention, despite increasing evidence of their various social functions. This paper aims to contribute to this under-researched area by drawing upon two individual case studies of Pakistani Muslim cricket teams; the first is based in the UK and the second in Norway. In this paper we argue that leisure and sport are key spaces for the delineation of social identities and hierarchies. We identify how cricket represents a significant social network within both the British and Norwegian Pakistani communities. In particular, we articulate the role of cricket in establishing and maintaining friendships and relationships, bolstering a sense of belonging, initiating diasporic sentiments, as well as being significant in the development of social capital, and resisting institutionalised white privilege
