This communique provides a summary of the production- and consumption-based greenhouse gas emissions accounts for Newfoundland and Labrador, as well as their associated trade flows. It is part of a series of communiques profiling the Canadian provinces and territories.1 In simplest terms, a production-based emissions account measures the quantity of greenhouse gas emissions produced in Newfoundland and Labrador. In contrast, a consumption-based emissions account measures the quantity of greenhouse gas emissions generated during the production process for final goods and services that are consumed in Newfoundland and Labrador through household purchases, investment by firms and government spending. Trade flows refer to the movement of emissions that are produced in Newfoundland and Labrador but which support consumption in a different province, territory or country (and vice versa). For example, emissions associated with the production of Newfoundland and Labrador crude oil that is exported to New Brunswick for refining and sale as motor gasoline are recorded as a trade flow from Newfoundland and Labrador to New Brunswick. Moving in the opposite direction, emissions associated with the production of a Quebec manufactured good that is exported to Newfoundland and Labrador for sale are recorded as a trade flow from Quebec to Newfoundland and Labrador. For further details on these results in a national context, the methodology for generating them and their policy implications, please see the companion papers to this communique series: (1) Fellows and Dobson (2017); and (2) Dobson and Fellows (2017). Additionally, the consumption emissions and trade flow data for each of the provinces and territories are available at: http://www.policyschool.ca/embodied-emissions-inputs-outputs-datatables-2004-2011/.
本公报概述了纽芬兰和拉布拉多以生产和消费为基础的温室气体排放占比,以及相关的贸易流量。它是介绍加拿大各省和地区的一系列公报的一部分简单地说,以生产为基础的排放账户衡量纽芬兰和拉布拉多产生的温室气体排放量。相比之下,以消费为基础的排放账户衡量的是纽芬兰和拉布拉多通过家庭购买、企业投资和政府支出消费的最终产品和服务的生产过程中产生的温室气体排放量。贸易流量指的是在纽芬兰和拉布拉多产生的、但支持另一个省、地区或国家消费的排放的流动(反之亦然)。例如,纽芬兰和拉布拉多原油出口到新不伦瑞克省进行精炼和作为汽车汽油销售,与生产相关的排放被记录为从纽芬兰和拉布拉多到新不伦瑞克省的贸易流。相反,魁北克制成品出口到纽芬兰和拉布拉多出售的过程中产生的排放被记录为魁北克到纽芬兰和拉布拉多的贸易流量。有关这些结果在国家背景下的进一步详细信息、产生这些结果的方法及其政策含义,请参阅本公报系列的配套论文:(1)Fellows and Dobson (2017);(2) Dobson and Fellows(2017)。此外,每个省和地区的消费排放和贸易流量数据可在http://www.policyschool.ca/embodied-emissions-inputs-outputs-datatables-2004-2011/上获得。

Multivariate Stochastic Volatility-Double Jump Model: An Application for Oil Assets 多元随机波动-双跳模型在石油资产中的应用
Pub Date : 2017-09-14 DOI: 10.2139/ssrn.3037158

We propose a new multivariate model to capture the presence of jumps in mean and conditional variance in the returns of oil prices and companies in this sector. The model is based on the presence of common factors associated with jumps in mean and variance, as it performs a decomposition of the conditional variance of each asset as the sum of the common factor plus a specific transitory factor in a multivariate stochastic volatility structure. The estimation is made through Bayesian methods using Markov Chain Monte Carlo. The model allows recovering the changes in prices and volatility patterns observed in this sector, relating the jumps with the events observed in the period 2000-2015. We apply the model to estimate risk management measures, hedging and portfolio allocation and performing a comparison with other multivariate models of conditional volatility. Based on the results, we may conclude that the proposed model has a better performance when used to calculate portfolio VaR, since it does not reject the hypothesis of correct nominal coverage with certain specifications presented in this work. Furthermore, we conclude that the model can be used to hedge oil price risks, through the optimal hedge ratio for a portfolio containing an oil company asset (stock) and the oil price contract. When compared to the standard methodology based on GARCH models, our model performs well in this application
我们提出了一个新的多元模型来捕捉石油价格和该行业公司回报中均值和条件方差跳跃的存在。该模型基于与均值和方差跳跃相关的共同因素的存在,因为它将每个资产的条件方差分解为多元随机波动结构中的共同因素加上特定临时因素的总和。利用马尔可夫链蒙特卡罗方法,通过贝叶斯方法进行估计。该模型可以恢复该行业观察到的价格变化和波动模式,并将其与2000-2015年期间观察到的事件联系起来。我们应用该模型来估计风险管理措施、对冲和投资组合配置,并与其他条件波动的多变量模型进行比较。根据结果,我们可以得出结论,所提出的模型在用于计算投资组合VaR时具有更好的性能,因为它没有拒绝在本工作中提出的某些规范下正确名义覆盖率的假设。进一步,我们得出结论,该模型可以通过包含石油公司资产(股票)和石油价格合约的投资组合的最优对冲比率来对冲石油价格风险。与基于GARCH模型的标准方法相比,我们的模型在该应用程序中表现良好

En algunas ocasiones, dos recursos naturales no renovables pueden compartir espacio fisico; este es el caso del gas y del petroleo cuando estan disponibles en el mismo campo de produccion. En la literatura economica no se ha analizado en profundidad las implicaciones de esta caracteristica sobre las decisiones de extraccion de una empresa que cuenta con ambos recursos. A diferencia del caso con yacimientos distantes, la proximidad entre los dos combustibles fosiles facilita la inyeccion de gas en los pozos de crudo, lo cual permite aumentar la extraccion de este ultimo. Ademas, se debe tener en cuenta la correlacion de los precios y las externalidades que ambos recursos generan sobre el medio ambiente ya que las decisiones de extraccion se vuelven interdependientes. Dadas las relaciones tecnicas y economicas entre el gas y el crudo cuando se encuentran en el mismo campo, en este documento se postula el problema dinamico de maximizacion de beneficios de una empresa que extrae los dos recursos, con el fin de encontrar las sendas optimas de extraccion de cada uno para un horizonte de tiempo finito. Los modelos propuestos se validan para el caso colombiano. Para esto, se lleva a cabo la parametrizacion de las funciones de costos y se realizan simulaciones para una ventana de tiempo de 26 anos. Los resultados muestran que, cuando hay disponibilidad de gas, es optimo realizar inyeccion en casi todos los periodos. Sin embargo, en un escenario de precios decrecientes la produccion de petroleo y la inyeccion de gas deben disminuir, mientras que la venta de gas debe aumentar. Finalmente, la implementacion de un impuesto a las emisiones de carbono disminuye marginalmente la cantidad total producida de combustibles fosiles, pero reduce significativamente las emisiones de carbono. Ademas, la sensibilidad al impuesto disminuye con el aumento del precio del crudo.
在某些情况下,两种不可再生的自然资源可能共享物理空间;这就是天然气和石油在同一生产领域的情况。在经济文献中,这一特征对拥有这两种资源的企业的开采决策的影响还没有深入分析。与遥远的油田不同,这两种化石燃料之间的距离较近,便于向油井注入天然气,从而增加了后者的开采。此外,必须考虑到价格的相关性和这两种资源对环境产生的外部性,因为开采决策变得相互依赖。鉴于tecnicas关系研究所之间的原油和天然气当处在同一个领域,在本文的问题企业利润maximizacion dinamico提取两个资源,以找到分别optimas extraccion地平线的每个时间有限。提出的模型在哥伦比亚的案例中得到了验证。本文提出了一种方法,通过对成本函数进行参数化,并对26年的时间窗口进行模拟。结果表明,在天然气可用的情况下,几乎所有时期都可以进行注入。然而,在价格下降的情况下,石油产量和天然气注入应该减少,而天然气销售应该增加。最后,碳税的实施略微减少了化石燃料的总产量,但显著减少了碳排放。此外,对税收的敏感性随着原油价格的上涨而降低。

We analyze the significance of an ice-free Northeast Passage (NEP) as a shipping route for LNG, and the impacts on alternative transport routes and -capacities. The following aspects are considered: (1) Trends in LNG production, particularly in the Russian Arctic; (2) Developments in the Asian LNG consumer market; (3) Specifics and prospects of Arctic shipping. The major LNG trade flows between producers and the Asian consumer market are modeled. Methods from Operations Research are contrasted and the Cycle-Cancelling Algorithm applied to the transportation problem, in order to achieve a cost-optimal capacity allocation. The impacts of demand variations and a chokepoint shutdown on transport routes and -capacities are considered. Concepts from competition theory are used to model the effects on LNG pricing. The key finding is that an ice-free NEP is highly relevant for shipping activities of Russian LNG producers. It constitutes a competitive advantage and notably impacts the supply competition and pricing on the Asian LNG market. A discussion of results and a conclusion critically reflect upon the research undertaken, providing an outlook and suggestions for future research.
我们分析了东北无冰通道(NEP)作为LNG航线的意义,以及对替代运输路线和能力的影响。考虑以下几个方面:(1)液化天然气生产的趋势,特别是在俄罗斯北极地区;(2)亚洲LNG消费市场的发展情况;(3)北极航运的特点和前景。对生产商和亚洲消费市场之间的主要液化天然气贸易流进行了建模。对比了运筹学的方法,并将周期取消算法应用于运输问题,以实现成本最优的容量分配。考虑了需求变化和阻塞点关闭对运输路线和运输能力的影响。竞争理论的概念被用来模拟对液化天然气定价的影响。关键的发现是,无冰NEP与俄罗斯液化天然气生产商的运输活动高度相关。这构成了竞争优势,并显著影响了亚洲液化天然气市场的供应竞争和定价。结果的讨论和结论批判性地反映了所进行的研究,为未来的研究提供了展望和建议。

Causal Relationship between Crude Oil Price, Energy Consumption and Carbon Dioxide (CO) Emissions in Ecuador 厄瓜多尔原油价格、能源消耗与二氧化碳排放的因果关系
Pub Date : 2017-09-01 DOI: 10.1111/opec.12102

This study examines the causal relationship between crude oil price, energy consumption and CO emissions in Ecuador over the period 1971–2013 incorporating indicators of economic performance. ARDL bounds testing approach to cointegration provides evidence of cointegration between the variables in the presence of structural break in the series. The long‐run effect of energy consumption on CO emissions in the oil‐dependent economy is found to be positive and statistically significant. The long‐run and short‐run causal effects of crude oil price on energy consumption and CO emissions in the economy are found positive and statistically significant, suggesting that higher crude oil prices create economic conditions that generate more energy consumption and CO emissions in the Ecuadorean economy. The direction of causality among the variables examined using Toda‐Yamamoto Granger causality test procedure suggests that a unidirectional causality runs from crude oil price to energy consumption and economic growth, and bidirectional causality between energy consumption and CO emissions. A unidirectional causality that flows from CO emissions to economic growth through financial development is also observed in the economy.
本研究考察了1971年至2013年期间厄瓜多尔原油价格、能源消耗和CO排放之间的因果关系,并结合经济表现指标。协整的ARDL边界检验方法提供了在序列中存在结构断裂的变量之间协整的证据。发现能源消耗对石油依赖型经济CO排放的长期运行效应是正的,且具有统计学意义。原油价格对经济中能源消耗和CO排放的长期和短期因果效应均为正的,且具有统计学意义,这表明较高的原油价格创造了经济条件,从而在厄瓜多尔经济中产生更多的能源消耗和CO排放。利用Toda‐Yamamoto Granger因果检验程序检验变量之间的因果关系方向表明,原油价格与能源消耗和经济增长之间存在单向因果关系,能源消耗与CO排放之间存在双向因果关系。在经济中也观察到二氧化碳排放通过金融发展流向经济增长的单向因果关系。

Option Prices Incorporate Fundamentals: Evidence from US Natural Gas Market 期权价格包含基本面:来自美国天然气市场的证据

We examine the incremental power of a large set of key fundamental, financial, and macroeconomic variables for forecasting the volatility of natural gas futures prices. Among other results, we find that the option implied volatility (IV) significantly improves the performance of predictions regarding the future volatility of the natural gas market. We also identify several fundamental and macroeconomic variables (e.g., open interests, default premiums, and the return of the housing index) which are statistically-significant in a predictive regression even after including the option implied volatility. On the other hand, we do not find a substantial increase in the adjusted-R2 of the predictive regressions (including IVs) after adding significant fundamental variables. The small incremental predictive power of fundamental variables is interpreted as a sign of the efficiency of the options market. We also observe that the adjusted-R2s of predictive regressions are higher when the time-to-maturity of the futures contract increases. Our results can help users of natural gas volatility forecasts (e.g., producers, utility companies, and portfolio managers) make better informed and more efficient operational and financial decisions.
我们研究了预测天然气期货价格波动的大量关键基础、金融和宏观经济变量的增量能力。在其他结果中,我们发现期权隐含波动率(IV)显著改善了对天然气市场未来波动率的预测。我们还确定了几个基本和宏观经济变量(例如,未平仓权益、违约溢价和住房指数的回报),即使在包括期权隐含波动率之后,这些变量在预测回归中也具有统计显著性。另一方面,在加入显著的基本变量后,我们没有发现预测回归(包括IVs)的调整后r2有实质性的增加。基本变量的小增量预测能力被解释为期权市场效率的标志。我们还观察到,随着期货合约到期日的增加,预测回归的调整后r2s更高。我们的研究结果可以帮助天然气波动率预测的用户(例如,生产商、公用事业公司和投资组合经理)做出更明智、更有效的运营和财务决策。

User-Intermediaries and the Local Embedding of Low Carbon Technologies 用户中介与低碳技术的局部嵌入
Pub Date : 2017-08-16 DOI: 10.2139/ssrn.3019957
Jake Barnes
This article draws on three theoretical fields, innovation intermediaries, socio-technical transitions and domestication studies to develop a process perspective of how user-side intermediary organisations seek to locally embed low carbon technologies. The term local embedding is increasingly used by transition researchers in a variety of ways. The first contribution of this paper is to explore and substantiate the concept of local embedding as the process of integrating technologies into local contexts of use. Intermediary organisations are conceived as contributing to local embedding where they facilitate, configure and broker change towards configurations that work. Nonetheless, understanding how these key intermediary processes relate as well as the influence of system dynamics on the work intermediaries undertake is still largely uncharted territory. The paper’s second contribution is a process perspective on the agency of intermediary organisations in local embedding. The resulting perspective offers insights into the agency of user-side intermediaries and later phases of transition processes.
本文借鉴了创新中介、社会技术转型和本土化研究三个理论领域,发展了用户侧中介组织如何寻求在当地嵌入低碳技术的过程视角。局部嵌入这一术语越来越多地被转移研究人员以各种方式使用。本文的第一个贡献是探索并证实了局部嵌入的概念,即将技术整合到本地使用环境中的过程。中介组织被认为有助于本地嵌入,在其中它们促进、配置和代理更改以实现有效的配置。尽管如此,了解这些关键的中介过程是如何关联的,以及系统动力学对中介工作的影响,在很大程度上仍然是未知的领域。本文的第二个贡献是中介组织在地方嵌入中的代理过程视角。由此产生的视角提供了对用户端中介的代理和转换过程的后期阶段的见解。

This paper develops a path for the global energy system up to 2050, presenting a new application of the open source energy systems model OSeMOSYS to the community. It allows quite disaggregate energy and emission analysis: GENeSYS-MOD (Global Energy System Model) uses a system of linear equations of the energy system to search for lowestcost solutions for a secure energy supply, given externally defined constraints, mainly in terms of CO2-emissions. The General Algebraic Modeling System (GAMS) version of OSeMOSYS is updated to the newest version and, in addition, extended and enhanced to include e.g. a modal split for transport, an improved trading system, and changes to storages. The model can be scaled from small-scale applications, e.g. a company, to cover the global energy system. The paper also includes an application of GENeSYS-MOD to analyze decarbonization scenarios at the global level, broken down into 10 regions. Its main focus is on interdependencies between traditionally segregated sectors: electricity, transportation, and heating. Model calculations suggests that in order to achieve the 1.5°-2° C target, a combination of renewable energy sources provides the lowest-cost solution, solar photovoltaic being the dominant source. Average costs of electricity generation in 2050 are about 4 €cents/kWh (excluding infrastructure and transportation costs).
本文提出了到2050年全球能源系统的发展路径,提出了开源能源系统模型OSeMOSYS在社区中的新应用。它允许相当分解的能源和排放分析:GENeSYS-MOD(全球能源系统模型)使用能源系统的线性方程系统来寻找安全能源供应的最低成本解决方案,给定外部定义的约束,主要是在二氧化碳排放方面。OSeMOSYS的通用代数建模系统(GAMS)版本更新到最新版本,此外,扩展和增强了包括运输的模式分割,改进的交易系统,以及对存储的更改。该模型可以从小型应用(例如公司)扩展到覆盖全球能源系统。本文还包括应用GENeSYS-MOD分析全球层面的脱碳情景,分为10个区域。它的主要重点是传统上隔离的部门之间的相互依赖关系:电力、交通和供暖。模型计算表明,为了实现1.5°-2°C的目标,可再生能源的组合提供了成本最低的解决方案,太阳能光伏是主要来源。2050年的平均发电成本约为每千瓦时4欧分(不包括基础设施和运输成本)。

Sulphur Abatement Globally in Maritime Shipping 全球海运中的硫减排
Pub Date : 2017-06-29 DOI: 10.2139/ssrn.2994757
H. Lindstad, C. Rehn, G. Eskeland
In 2016, the International Maritime Organization (IMO) decided on global regulations to reduce sulphur emissions to air from maritime shipping starting 2020. The regulation implies that ships can continue to use residual fuels with a high sulphur content, such as heavy fuel oil (HFO), if they employ scrubbers to desulphurise the exhaust gases. Alternatively, they can use fuels with less than 0.5% sulphur, such as desulphurised HFO, distillates (diesel) or liquefied natural gas (LNG). The options of lighter fuels and desulphurisation entail costs, including higher energy consumption at refineries, and the present study identifies and compares compliance options as a function of ship type and operational patterns. The results indicate distillates as an attractive option for smaller vessels, while scrubbers will be an attractive option for larger vessels. For all vessels, apart from the largest fuel consumers, residual fuels desulphurised to less than 0.5 % sulphur are also a competing abatement option. Moreover, we analyse the interaction between global SOX reductions and CO2 (and fuel consumption), and the results indicate that the higher fuel cost for distillates will motivate shippers to lower speeds, which will offset the increased CO2 emissions at the refineries. Scrubbers, in contrast, will raise speeds and CO2 emissions.
2016年,国际海事组织(IMO)决定制定全球法规,从2020年开始减少海运对空气中的硫排放。该规定意味着,如果船舶使用洗涤器对废气进行脱硫,则可以继续使用含硫量高的残余燃料,如重质燃料油(HFO)。或者,他们可以使用含硫量低于0.5%的燃料,如脱硫的重油、馏分油(柴油)或液化天然气(LNG)。较轻燃料和脱硫的选择需要费用,包括炼油厂较高的能源消耗,本研究根据船型和作业模式确定并比较了遵守的选择。结果表明,馏分油是小型容器的有吸引力的选择,而洗涤器将是大型容器的有吸引力的选择。对于所有船舶来说,除了最大的燃料消耗者之外,脱硫至低于0.5%硫的残余燃料也是一种有竞争力的减排选择。此外,我们分析了全球SOX减排与二氧化碳(和燃料消耗)之间的相互作用,结果表明,馏分油的更高燃料成本将激励托运人降低速度,这将抵消炼油厂增加的二氧化碳排放。相比之下,洗涤器将提高速度和二氧化碳排放量。

Scaling Up Distributed Solar in Emerging Markets: The Case of the Arab Republic of Egypt 在新兴市场扩大分布式太阳能:以阿拉伯埃及共和国为例

Like many emerging markets, the Arab Republic of Egypt is keen to promote distributed solar, defined here as systems below 500 kilowatts, but has struggled to create conditions for growth in the sector. The aim of this paper is to identify policy actions to unlock the distributed solar market for on-grid and off-grid applications, using Egypt as a case study. The paper calculates the rate of return on investment for different distributed solar applications, identifies nonfinancial barriers to scaling up distributed solar, and derives policy implications. For on-grid applications, the analysis finds that neither net metering nor the feed-in tariff makes distributed solar financially attractive, despite recent reductions in electricity subsidies and adjustments of feed-in tariff levels in October 2016. For off-grid applications, the profitability of distributed solar depends highly on the local price of diesel: distributed solar is viable only in areas where diesel is not available at the official (subsidized) price. In addition, several nonfinancial barriers limit the scalability of the distributed solar market. These findings indicate that the distributed solar market in Egypt will remain a niche market in the next few years without strengthened government support. First, for on-grid applications, the net metering scheme should be kept in place until a bankable feed-in tariff has been established. Second, for off-grid applications, the government should explore interventions to unlock opportunities in the agriculture and tourism sectors. Third, the government should strengthen private-sector activity in the sector, including by addressing nonfinancial barriers, such as transaction costs and gaps in the availability of data, and by building capacity among users, suppliers, and financial institutions.
像许多新兴市场一样,阿拉伯埃及共和国热衷于推广分布式太阳能,这里的定义是500千瓦以下的系统,但一直在努力为该行业的增长创造条件。本文的目的是确定政策行动,以解锁分布式太阳能市场的并网和离网应用,并以埃及为案例研究。本文计算了不同分布式太阳能应用的投资回报率,确定了扩大分布式太阳能的非金融障碍,并得出了政策含义。对于并网应用,分析发现,尽管最近电力补贴减少,并于2016年10月调整了上网电价水平,但净计量和上网电价都没有使分布式太阳能在财务上具有吸引力。对于离网应用,分布式太阳能的盈利能力在很大程度上取决于当地的柴油价格:分布式太阳能只有在柴油无法以官方(补贴)价格获得的地区才可行。此外,一些非金融障碍限制了分布式太阳能市场的可扩展性。这些发现表明,如果政府不加强支持,未来几年埃及的分布式太阳能市场仍将是一个利基市场。首先,对于并网应用,净计量方案应该保持到位,直到建立一个可获得银行支持的上网电价。其次,对于离网应用,政府应该探索干预措施,以释放农业和旅游业的机会。第三,政府应加强私营部门在该领域的活动,包括解决非金融障碍,如交易成本和数据可用性方面的差距,以及在用户、供应商和金融机构之间建立能力。
