Low emission zones: the likely effects on the freight transport sector

London’s air quality has improved over recent decades, but is still the worst in the UK. Road transport emissions play an important part in this pollution. A low emission zone (LEZ) would help to accelerate the introduction of cleaner vehicles, and reduce the numbers of older, more polluting vehicles operating in London. The survey work carried out indicates that there is support among goods vehicle operators for an LEZ in London, depending on the precise scheme definition. Operators would generally try to comply with LEZ regulations, with most companies either using technical approaches to ensure that their London vehicle fleet complied with the required emission standard or by redeploying vehicles with the appropriate emission standard from other locations.

E-learners’ experiences of time

This paper explores the experiences of e-learners participating in continuing professional development programmes in three UK universities. Data was collected using questionnaires, discussion group postings and informal telephone interviews. These were analysed using two approaches to content analysis: a coding scheme and metaphors. Findings indicated that: e-learners reconstruct their approaches to time management at an early stage in their programme; the e-learners developed different time management strategies (planned, opportunistic, planned/opportunistic); and metaphors illustrated their underlying experiences of time. These provide the basis of recommendations for e-tutors. Finally, the paper explores methodological issues and outlines some implications for practice.

Towards a Systematic Framework for the Modelling of the Allocation of Carbon Dioxide Emission Quotas in China

The needs for effectively controlling carbon dioxide emissions and properly allocating carbon dioxide emission permits or allowances in China have never been so great. In this paper, a systematic multi-agent-based framework for the modelling and analysis of the allocation of carbon dioxide emission quotas in China is proposed. A carbon trading market model as the core of the activities of allocation management is constructed and discussed. In addition, examples of the modelling and simulation work are presented.
