基于协调度函数的碳排放初始权区域分配模型研究

针对目前碳排放初始权区域分配模型中分配原则、指标体系不一致的问题,提出了碳排放初始权区域分配协调度概念,并确定了公平性原则、效率性原则、可持续发展原则、保障工业生产原则、保护环境原则作为碳排放初始权区域分配的具体原则,构造了基于各个分配原则下的碳排放初始权区域分配协调度子函数,建立了以碳排放初始权分配系统协调度最大为目标的协调度分配模型。将此模型应用到华东电网区域的碳排放初始权分配中,结果表明该模型合理、有效、可行性高,能较好的兼顾各个分配原则。该区域分配模型不依赖分配指标体系,能有效避免分配指标体系混乱问题,所建立的模型可以为碳排放初始权区域分配的研究提供借鉴。

基于城市交通平等路权的视角应对城市环境问题的法律路径

城市交通路权的分配影响城市环境变化问题,并关涉城市居民的出行、健康与生活舒适度。城市交通路权分配与城市环境变化问题之间存在着紧密的关联性。现阶段,我国法律中还未有关于路权的定义,而我国城市走上了以机动车为核心、构建快速交通系统的发展模式,忽视了甚至破坏了原有的城市慢行系统的存在,产生了很多城市环境问题。构建基于城市交通平等路权的应对城市环境变化的法律制度,符合我国的迫切现实需求。我国经济的快速发展,城市规模的不断扩大与可持续发展中以人为本的原则之间的矛盾从理论上要求我国应当以城市交通平等路权为切入点构建应对环境变化的法律,从而改善环境增加人民生活的满意度。     

Serving one another: Are shared and self‐leadership the keys to service sustainability?

Service has received increasing attention in the management literature, yet sustainability of service is often overlooked. In this Incubator we examine the potential for client involvement through shared and self‐leadership to foster empathy enhanced service and reduced costs, both of which may support a more sustainable service delivery process.

Compromising sustainable mobility? The case of the Gothenburg congestion tax

Congestion charging is widely considered an effective policy measure to regulate and reduce car traffic demand and associated environmental and health problems in cities. However, introducing restrictive measures to constrain individual choice and behaviour for the common good has often proven difficult. Using a specific case, the Gothenburg congestion tax introduced in 2013, we study the policy process behind the introduction of the tax and assess to what extent green values were compromised along the way. The tax was made possible by co-financing infrastructure investments, including roads, which seemingly contradicts stated goals of reducing car traffic and emissions. We show how the tax was ‘muddled through’ in a top-down political compromise by a grand coalition where different interests could legitimate their support in relation to the achievement of partially conflicting objectives and projects. However, to declare the regulatory goals fully neutralised would be to underestimate the scheme's direct environmental effects and restrictive potential. Finding a compromise with powerful political and economic interests was necessary to get it off the ground. Once launched, however, it can over time regain its restrictive properties and lead to more profound long-term effects.     

Spatial allocation of material flow analysis in residential developments: a case study of Kildare County,Ireland

Studies of urban metabolism provide important insights for environmental management of cities, but are not widely used in planning practice due to a mismatch of data scale and coverage. This paper introduces the Spatial Allocation of Material Flow Analysis (SAMFA) model as a potential decision support tool aimed as a contribution to overcome some of these difficulties and describes its pilot use at the county level in the Republic of Ireland. The results suggest that SAMFA is capable of identifying hotspots of higher material and energy use to support targeted planning initiatives, while its ability to visualise different policy scenarios supports more effective multi-stakeholder engagement. The paper evaluates this pilot use and sets out how this model can act as an analytical platform for the industrial ecology–spatial planning nexus.     

Comparing Green and Grey Infrastructure Using Life Cycle Cost and Environmental Impact: A Rain Garden Case Study in Cincinnati,OH

Green infrastructure (GI) is quickly gaining ground as a less costly, greener alternative to traditional methods of stormwater management. One popular form of GI is the use of rain gardens to capture and treat stormwater. We used life cycle assessment (LCA) to compare environmental impacts of residential rain gardens constructed in the Shepherd's Creek watershed of Cincinnati, Ohio to those from a typical detain and treat system. LCA is an internationally standardized framework for analyzing the potential environmental performance of a product or service by including all stages in its life cycle, including material extraction, manufacturing, use, and disposal. Complementary to the life cycle environmental impact assessment, the life cycle costing approach was adopted to compare the equivalent annual costs of each of these systems. These analyses were supplemented by modeling alternative scenarios to capture the variability in implementing a GI strategy. Our LCA models suggest rain garden costs and impacts are determined by labor requirement; the traditional alternative's impacts are determined largely by the efficiency of wastewater treatment, while costs are determined by the expense of tunnel construction. Gardens were found to be the favorable option, both financially (~42% cost reduction) and environmentally (62‐98% impact reduction). Wastewater utilities may find significant life cycle cost and environmental impact reductions in implementing a rain garden plan.     

Towards a governance of sustainable consumption transitions: how institutional factors influence emerging local food systems in Belgium

System innovations and transitions in the realm of sustainable consumption policies will seldom emerge automatically from the present socio-political and socio-technical contexts. This paper explores a set of perspectives related to the governance of transitions and develops their application to the relatively unexplored governance of sustainable consumption transitions. Empirical material stems from an extensive case study which analyses a food consumption niche in the form of collectively organised local food systems (LFS) in Belgium. More specifically, we analyse and discuss the institutional contexts and socio-political configurations within which the investigated system innovation cases are embedded. The results explore the role of governmental interplay in fostering innovative consumption practices for a transition towards a more sustainable, autonomous, citizen-based, LFS.     

(Dis)connected communities and sustainable place-making

Why, despite a recent surge in the UK in “sustainable communities” policy discourse, do so many community-led sustainability initiatives remain fragmented, marginal and disconnected from local government strategies? How can community- and government-led sustainability initiatives be better integrated such that they add significantly to a denser matrix and cluster of sustainable places? These questions, we argue, lie at the heart of current sustainable place-making debates. With particular reference to two spatial scales of analysis and action, the small town of Stroud, England and the city of Cardiff, Wales, we explore the twin processes of disconnection and connection between community sustainability activists and local state actors. We conclude that whilst there will always remain a need for community groups to protect the freedom which comes from acting independently, for community activists and policy-makers alike, there are nevertheless a series of mutual benefits to be had from co-production. However, in setting out these benefits we also emphasise the dual need for local government to play a much more nuanced, integrative and facilitatory role, in addition to, but separate from, its more traditional regulatory role.
