北京首都机场绿色滑行时间估算

采用北京首都机场2014年实际CDM地面放行数据确定航空器的污染物排放量与离场排队飞机数量和落地滑入飞机数量的强关联性,构建包含这两个解释变量为影响因素的多元线性回归模型,用以估算几种常见机型在首都机场地面运行时的最小污染物排放量和绿色滑行时间。对比实际污染物排放量与最小污染物排放量,得出首都机场离场地面污染物排放量远远超过最小污染物排放量。

确定河流污染物综合降解系数动态变化规律对提高水环境容量测算精度和水环境管理具有重要意义。通过现场模拟法,采用一维稳态模型测算了淮河支流洪河五沟营-塔桥乡河段COD、氨氮和总磷在枯水期、平水期和丰水期的综合降解系数,COD、氨氮和总磷降解系数在各水期的关系为枯水期平水期丰水期,提出了建议值并利用实测浓度对计算结果进行了检验,结果表明,不同水期综合降解系数吻合情况较好。     

Local hegemonies resisting a green shift and what to do about it: the introduction of a regional park in southern Norway

In the Lister region in the southern part of Norway, attempts are currently being made to facilitate for a green shift. The paper discusses two different approaches towards such a challenge. The first is procedural, where success or failure hinges on the methods applied in the effort to convince locals to incorporate climate considerations. The alternative is to reflect upon how a green ideology blends into pre-existing ideological elements in the region. It is claimed that an important reason for the failure so far to place the environment at the core of regional development, is that too much emphasis has been put on the first approach, on procedure and dialogue, whereas few efforts have been made to understand the structure of the discursive terrain in the region. What prevents a green shift has less to do with methods and is more connected to the dominance of a logic of economic growth and the fact that locals are confident that nature is already dealt with in a sensible manner. The conclusion is that we need to understand what people are concerned about and what prevents them to change, before we start telling them how to think and do development.

经环境污染损失调整的重庆市绿色GDP核算研究及应用

传统的GDP核算模式建立在资源耗减、环境破坏和公众健康不断透支的基础之上,不能体现经济活动对自然资源的消耗和对生态环境造成的破坏。为了将环境污染损失纳入GDP核算体系,以2010年重庆市绿色GDP核算为例,运用虚拟治理成本法进行环境价值量核算。结果表明,基于环境污染损失调整后的重庆市绿色GDP为7920.28亿元,污染扣减指数为0.4%。     

《京都》15年后:分阶段减排政策与“绿色悖论”问题

低碳经济的政策分析,通常囿于单一国家层面的局部均衡结果,较少考虑到全球整体行动的外部影响,但从《联合国气候变化框架公约》建立以来的全球一致减排行动,却产生了一些意料之外的负面效果。本文通过梳理《京都议定书》签订以来,全球低碳经济合作中遇到的新挑战,以及碳交易市场的建设状况,采用制度分析与新古典框架下的市场均衡分析方法,讨论了全球一致减排行动所触发的"绿色悖论"问题。研究发现,造成"绿色悖论"的主要原因,一方面是由于国际合作存在制度设计上的缺陷,《京都议定书》及其关键性的附件一,将重点放在如何限制发达工业国的减排设计上,但却忽视了发展中国家在协议期内有可能出现的增排问题,以及发达国家向发展中国家污染转移的碳泄漏等问题;另一方面,当对不可再生资源的使用征税、以及对其替代品进行补贴时,将会导致在当前期对于化石能源的加速开采,并可能导致对同时期的化石燃料替代品的其他可再生资源的开采速度也大幅度加快,造成了在双重加速开采下的全球绿色福利损失以及CO2排放量的急剧升高,化石能源消费与温室气体排放面临到比协议签署前更为严峻,甚至与全球合作减排框架的设计初衷相悖的结果。研究结果表明,非全局性的减排公约和分阶段的减排政策,是造成"绿色悖论"现象的重要条件,缺少了大量发展中国家和一些重要工业国的缔约,使得负面的环境外部性难以克服;同时,减排任务和责任有所区别的分阶段设计,会把在未来行动期内可预见到的更高地化石能源使用成本转嫁到当前的行动期,造成短时间内资源与环境的迅速破坏。但本文的研究也表明,社会最优经济与对可再生能源进行补贴是克服"绿色悖论"现象的两条可行路径,且需要有与其相匹配的政府政策的支持。由此,本文的主要政策建议是,中国需要加强在国际气候公约中的影响力,提升自身话语权;以碳税政策作为发展低碳经济制度设计的主要政策工具;加快技术进步、提高能源使用效率,对于可再生能源研发进行补贴;根据国情不断优化碳税税率,并适时调整与其相匹配的新能源补贴等相关政策。     

SMART-SREC: A stochastic model of the New Jersey solar renewable energy certificate market

Markets for solar renewable energy certificates (SRECs) are gaining in prominence in many states, stimulating growth of the US solar industry. However, SREC market prices have been extremely volatile, causing high risk to participants and potentially less investment in solar power generation. Such concerns necessitate the development of realistic, flexible and tractable models of SREC prices that capture the behavior of participants given the rules that govern the market. We propose an original stochastic model called SMART-SREC to fill this role, building on established ideas from the carbon pricing literature, and including a feedback mechanism for generation response to prices. We calibrate the model to the New Jersey market and backtest it, analyzing parameter sensitivity and demonstrating its ability to reproduce historical dynamics. Finally, we run simulations to investigate the role and impact of regulatory parameters, thus providing insight into the crucial role played by market design.

The potential implementation of green infrastructure assessment using high-resolution National Agriculture Imagery Program data for sustainable hazard mitigation

As green infrastructure gets its attention in hazard mitigation, it is necessary to improve general understanding on what makes green infrastructure important for hazard and resiliency research. To better understand how green infrastructure fits with more traditional notions of structural and nonstructural mitigation, this study examines the relationship between green infrastructure and ‘structural and nonstructural’ mitigation approaches for hazard mitigation. Also, this study discusses a new measurement of locational aspects and spatial patterns of green infrastructure by utilizing high-resolution data in urban areas, and its potential implementation in hazard mitigation. Compared to previous research using land-use land-cover datasets, the normalized difference vegetation index (NDVI) utilizing National Agriculture Imagery Program dataset provides an ability to capture green infrastructure in greater detail. A visual comparison suggests that the NDVI data are able to capture and identify more types of ‘green’ land uses in Harris County. The total green infrastructure percentages for Harris County, Texas, based on 1-m high resolution were found to be 61.5% of the area, compared to the 51.5% based on the National Land Cover Database. This study provides support for utilizing high-resolution data to establish guidelines for green infrastructure’s spatial characteristics and sustainable hazard mitigation. The outcomes of this study will be helpful in the strategic planning and implementation of green infrastructure in urban areas with hazard issues.
