Abstract: Global temperature rise over the long term will be proportional to the total amount of CO2 emitted. Any given probability of exceeding a targeted maximum temperature rise implies a maximum limit on the cumulative total of CO2 that can be emitted: a CO2 “budget”. This paper describes an approach to modelling cumulative emissions from light and heavy duty road transport from the present to 2050, focussing on the USA and Europe, and comparing the potential impacts of a range of technological and behaviourally-based abatement measures with such cumulative emissions budgets. The model shows that abatement measures would have a lower effect on cumulative emissions from 2000 to 2050 than on annual emissions in 2050, so that focussing only on annual emissions could be misleading. It shows that technological developments would be insufficient on their own to enable Europe and the USA to meet CO2 budgets for road transport. Behavioural changes, which potentially can be implemented much sooner, would be essential too. There is potential to keep European light duty emissions very close to CO2 budgets, and US light duty emissions not far above the least restrictive budget, but the model predicts that heavy duty emissions in both regions are likely to exceed their CO2 budgets. Deeper emissions reductions in other regions and sectors will be needed to compensate for this. Timing would be critical: for the greatest impact, behaviour change policies and interventions would need to be applied early and deeply. [Copyright &y& Elsevier]

Town centre management (TCM) has evolved considerably over the last 25 years in terms of both its purpose and methods. Whilst most reviews of TCM to date have focused on its development within the Anglo-Saxon world (typically North America and the United Kingdom), comparatively little attention has been given to other models of place and town centre management that have emerged across Europe. This paper seeks to redress the balance by exploring the relevance of other models from a number of European countries, which were researched using a case study approach and conceptualised within a framework which seeks to classify TCM schemes by their funding sources and structural formality. It is argued that, despite their lower budgets or lack of formal recognition, other models of TCM such as informal place management schemes or hybrids of formal and informal TCM schemes can often be just as effective in delivering positive outcomes for urban communities.
