以广州市为例,应用长期能源替代规划系统（LEAP）模型,通过设置政策情景、低碳情景和绿色低碳情景,模拟不同发展情景下广州交通领域未来的能源消费需求和CO2排放趋势,分析城市低碳发展的方向和路径。结果显示,随着城镇化进程的加快和生产生活运输需求的增加,广州交通领域碳排放总量将持续增长,但增长速度有所放缓。政策情景下,广州交通领域的CO2排放将于2035年左右达到峰值,严重滞后于广州市提出的碳排放总量达峰目标;低碳和绿色低碳情景下,通过加大低碳政策措施的力度,达峰时间有望分别提前到2025年和2023年。要实现城市交通的低碳发展,促进交通碳排放提前达峰,需要大力发展铁路和水路运输,全面落实公交优先发展战略,有效控制小汽车数量和出行频率,不断提高交通工具的清洁化和能效水平,逐步形成各种运输方式协调发展的综合交通运输体系,推动城市交通低碳发展。 相似文献

The purpose of this article is to analyze the advances of, and obstacles to, progressive attempts at modifying the balance of power over water through the use of the law as a tool for social transformation and to characterize the alternatives based on the ways in which they challenge neoliberal principles. The study of such dynamics using a broad perspective on the law which includes not only written laws, but also historical moments in which water laws were created and used, provides a platform to discern alternatives that in many cases might otherwise remain invisible.We critically analyze the major legal contradictions and tensions in Bolivia, Colombia and Peru that suggest post- and counter-neoliberal alternatives. First, certain alternatives indicate a break from neoliberal principles based on relational ontologies (that avoid divisions between nature and culture as well as between individuals and communities). Such breaks include the statement that water is a common good or a common resource for the benefit of all, the goal to re-establish the human connection with nature, and support for a water provision system based on reciprocity, community and cooperative principles. Second, additional proposals that can be characterized as counter-neoliberal oppose neoliberal means or outcomes, such as proposals for more equitable water allocation or inclusive participation mechanisms for decision making. Both counter- and post-neoliberal alternatives also find much resistance in water laws; however, they do represent progressive alternatives that reach state laws and challenge neoliberal conceptions of nature. 相似文献

Community economies can be considered as examples of the diverse economies growing outside common capitalist logics of private accumulation and profit, seeking to bypass or reconfigure dominant global trends of societal and economic organization. Yet, these communities seem to fit quite well under a neoliberal program in which responsibilities are shifting downwards, favoring multi-level governance over State intervention and accountability. This binary character makes imperative an open and critical discussion on the development of community initiatives, including on the motivations and visions of citizens practicing alternative ethical consumption. This article explores the neoliberal rationalities embraced by community members within the imaginaries of change they frame and examines how these rationalities contribute to (re)producing neoliberal conditions and forms of governance. Our analysis builds on semi-structured interviews conducted among the members of 11 initiatives in 5 EU countries and on participant observation. We argue here that communities articulate an “alternative imaginary” of change that appears imprinted by core neoliberal rationalities around questions of individual responsibility, the role of the State, and civic participation and equity. It is an imaginary related to the construction of CBEs to by-pass existing socio-political and economic configurations. This imaginary more often than not responds to neoliberal promises of individual freedom and autonomy and seems to undermine CBEs' more radical possibilities at the same time obscuring more diverse voices of transformation. 相似文献
