City Partners Maintain Climate Change Action Despite National Cuts: Residential Energy Efficiency Programme Valued at Local Level

Cities, regional governments and their local utilities are taking leading roles in programmes to reduce greenhouse gas emissions. Agenda 21 highlighted the need for such local action to achieve the goals of the 1992 Earth Summit and the United Nations Framework Convention on Climate Change. This trend of increasing local action was demonstrated dramatically in Canada in 2006 when the newly elected federal government cancelled many of the previous government's climate change programmes. The EnerGuide for Houses Program illustrates the growing importance of local decisions where the federal government developed a home energy rating system that was delivered through a range of partnerships across the country. Despite all political parties voting to increase funding for the programme in 2005, the Conservative government cancelled it in May 2006. The response by provincial and local governments was immediate. Their actions revealed the ability and desire among lower-tier governments to sustain popular climate change initiatives. Both the political responses and financial implications are included in the examination of the shift in environmental responsibility from the national to the local sphere.

Changing places, changing emissions: The cross-scale reliability of greenhouse gas emission inventories in the US

Greenhouse gas (GHG) emission inventories, which currently inform abatement policy discussions, are developed mostly from national scale data. Nevertheless, although the policy debate tends to take place in global and national arenas, action to abate GHG emissions is inherently within the provenance of local institutions and communities. The purpose of this paper is to examine how much information is lost by not estimating GHG emissions data at scales finer than the whole US. Such information may be critical in bridging global and local policy. Differences in the composition of GHG emission sources based on GHG emission inventories at three nested spatial scales (national, state, local) for four study sites (in Kansas, North Carolina, Ohio and Pennsylvania) are analysed, drawing upon initial results of a large collaborative study known as the 'Association of American Geographers-Global Change in Local Places (GCLP)' project. The concept of spatial sovereignty of emissions is developed to test the cross-scale reliability of emission inventories. For the test year 1990, close agreement is found in the by-gas composition of GHG emissions among national, state and local inventories. Spatial sovereignty in this case is maintained. However close agreement is not found in the by-source composition of GHG emissions among national, state and local inventories. Spatial sovereignty in this case is not maintained. Regular compilation of state and local emissions source inventories may be necessary to track important spatial and temporal deviations from national trends.     

The effective practices of mobile phone producers' green supply chain management in reducing GHG emissions

The aim of this study is to identify management practices that effectively reduce greenhouse gas (GHG) emissions with regard to the green supply chain adopted by mobile phone producers. Six cases were surveyed (Apple, Samsung, LG, Huawei, Nokia, and ZTE). The main source of data was sustainability reports, which were retrieved from the Global Reporting Initiative database. A special data analysis technique called rank analysis was adopted. The results revealed that the effective practices to reduce GHG 1 emissions were related to production process and business travel; those that were effective for reducing GHG 2 emissions were related to facilities accreditation and energy saving; and those effective in reducing GHG 3 emissions were related to logistics and customer practices. No effective actions related to the management of relationships with suppliers were identified by this study. Indicative models for the relationship between actions and GHG emissions were developed, as was a value‐stream map. The previous studies reporting the effective practices in other industries reported results for reducing GHG 1 or GHG 3, or overall GHG emissions, without discriminating among the actions taken to reduce such emissions, although some limited actions were reported. This study describes the effective practices along the whole supply chain—both upstream and downstream—and it also lists the actions related to addressing all the emissions, whether GHG 1, 2, or 3.     

“一带一路”视域下环境保护问题的战略定位与治理体系

环境保护是"一带一路"建设的重要议题,它所面临的挑战更多源于沿线国家和地区经济发展任务繁重与生态环境先天脆弱之间的矛盾。仅仅依靠单个政府部门或某一政策,或者仅仅依靠单个国家或地区的某一倡议与行动,均不足以应对"一带一路"建设中的跨国环境风险,这将倒逼国内与国际社会提升环境保护的战略地位,构建新型环境治理体系。"一带一路"沿线的各地政府不仅要发挥生态环保的示范作用,还要建立横向若干部门和纵向各级政府的协同治理机制,完善环境保护跨国合作制度,鼓励企业、NGO组织与民间力量、智库共同参与环境治理。     

Economy wide impacts of ethanol and biodiesel policy in Canada: An input–output analysis

The Government of Canada has committed that Canada’s total greenhouse gas (GHG) emissions be reduced by 17% from 2005 levels by 2020. The new Renewable Fuels Regulations required 2% renewable content in diesel fuel and heating distillate oil and 5% for gasoline. This represents approximately 2.1 billion liters of ethanol and 600 million liters of biodiesel requirement per year, which would reduce GHG emissions by more than four million tones. Canada is expected to consume more fuel ethanol compared to its production capacity. The above mandates as well as the gap in consumption and production of biofuel will have enormous impact on the Canadian economy. In this backdrop, an input–output model of the Canadian economy is developed to estimate the macroeconomic impact of the ethanol and biodiesel production in Canada. The impacts on sectoral prices have also been calculated. Simulation exercises have been attempted to reach the mandates using modified Leontief model. Results show that agriculture sector is affected because of feedstock use in the biofuel sector. Mining and manufacturing industries also show a considerable impact. In addition, the impact on commodity prices cannot be ignored. Finally, to meet the target of Copenhagen commitment, the nation needs to revise the blending capacity of ethanol and biodiesel.     

Urban climate change and sustainability planning: an analysis of sustainability and climate change discourses in local government plans in Canada

This paper clarifies the competing discourses of sustainability and climate change and examines the manifestation of these discourses in local government planning. Despite the increasingly significant role of sustainability and climate change response in urban governance, it is unclear whether local governments are constructing different discourses that may result in conflicting approaches to policy-making. Using a governmentality approach, this paper dissects the contents of 15 Canadian local governments’ sustainability plans. The findings show that there are synergies and tensions between discourses of sustainability and climate change. Both share discursive space and shape local governance rationalities, though climate change response logics are not necessarily highlighted even where the action could result in greenhouse gas (GHG) emission reductions. In some cases, existing GHG intensive practices are being rebranded as ‘sustainable’. This suggests a tension between discourses of sustainability and climate change that may complicate attempts to address climate change through local sustainability planning.     

Green economy: Private sectors’ response to climate change

The focus of this paper is to present a discussion of the role of the private sector in response to the need for climate change adaptations. The study, which was conducted through a literature review, investigates the concept of the green economy and climate change, as well as businesses’ commitment to advance climate actions in ways that build resilience in vulnerable communities in developing countries. The paper calls on companies with national, regional, and/or global reach to adopt or develop strategies that improve resource efficiency, reduce greenhouse gas emissions, and reduce the loss of biodiversity. Businesses can accelerate this transition by aligning their investments with climate change adaptation opportunities, and thus, “green” the economy. In addition, green growth could be achieved through tactical public and private investments in mitigating climate change. The paper concludes that the private sector is a key sector in addressing the challenges of vulnerable communities, and it has much to contribute to the planning, development, and implementation of climate adaptation strategies, including sector‐specific expertise, technology, efficiency, financing, and entrepreneurship. Finally, some social conditions and environmental boundaries have been highlighted in this paper to attract the attention of business leaders who are trying to build initiatives and advance climate actions that will reduce socio‐community risks from climate change. Also, comprehensive initiatives and strategies have been recommended to private companies seeking to address climate vulnerabilities.     

Universities and Climate Change Mitigation: Advancing Grassroots Climate Policy in the US

Abstract

While US climate change mitigation policy has stalled at the national level, local and regional actors are increasingly taking progressive steps to reduce their greenhouse gas emissions. Universities are poised to play a key role in this grassroots effort by targeting their own emissions and by working with other local actors to develop climate change mitigation programmes. Researchers at the Pennsylvania State University have collaborated with university administrators and personnel to inventory campus emissions and develop mitigation strategies. In addition, they have facilitated a stakeholder-driven climate change mitigation project in one Pennsylvania county and started an ongoing service-learning project aimed at reducing emissions in another county. These campus and community outreach initiatives demonstrate that university-based mitigation action may simultaneously achieve tangible local benefits and develop solutions to broader challenges facing local climate change mitigation efforts. Outcomes include improved tools and protocols for measuring and reducing local emissions, lessons learned about service-learning approaches to climate change mitigation, and methods for creating climate change governance networks involving universities, local governments and community stakeholders.

Mitigation paths for Chinese iron and steel industry to tackle global climate change

Based on a recognition of the essence of climate change and the pressure on China to reduce its greenhouse gas (GHG) emissions, this paper interprets the important role that the Chinese iron and steel industry may play in managing emissions. Through an investigation of the key sources of GHG emissions in the Chinese iron and steel industry, a comparison of the current Chinese and international situations, and a survey of the technology and methods available for reducing GHG emissions, and their application in China, the authors analyze the major issues currently faced by the Chinese iron and steel industry, and propose the following four approaches through which the industry might reduce its GHG emissions: (1) encouragement of clean development mechanism (CDM) projects, mainly involving secondary energy reuse, to provide capital and technology for GHG reduction activities in China; (2) stimulation of the social responsibility-based voluntary carbon market (VCM) to increase the long-term benefits for the Chinese iron and steel industry from emission reductions; (3) undertaking of strict energy auditing to help enterprises establish appropriate emission reduction targets and formulate reasonable plans; (4) promotion of emission reduction-oriented investment within the industry to obtain profits from project operation, while at the same time gaining extra compensation for emission reductions. More specifically, the design of each of these approaches should take into consideration the related economic factors and incentive mechanisms.     

Solid Waste Treatment as a High-Priority and Low- Cost Alternative for Greenhouse Gas Mitigation

The increased concern about environmental problems caused by inadequate waste management, as well as the concern about global warming, promotes actions toward a sustainable management of the organic fraction of the waste. Landfills, the most common means to dispose of municipal solid waste (MSW), lead to the conversion of the organic waste to biogas, containing about 50% methane, a very active greenhouse gas (GHG). One unit of methane has a global warming potential of 21 computed for a 100-year horizon or 56 computed for 20 years. The waste sector in Israel contributes 13% of total greenhouse gases (GHG) emissions for a time horizon of 100 years (for a time horizon of 20 years, the waste sector contribution equals to more than 25% of total GHG emissions). The ultimate goal is to minimize the amount of methane (CH₄) by converting it to CO₂. This can be achieved by physicochemical means (e.g., landfill gas flare, incineration) or by biological processes (e.g., composting, anaerobic digestion). Since the waste in Israel has a high organic material content, it was found that the most cost-effective means to treat the degradable organic components is by aerobic composting (investment of less than US$ 10 to reduce emission of one ton CO₂ equivalent per year). Another benefit of this technology is the ability to implement it within a short period. The suggested approach, which should be implemented especially in developing countries, could reduce a significant amount of GHG at relatively low cost and short time. The development of a national policy for proper waste treatment can be a significant means to abate GHG emissions in the short term, enabling a gain in time to develop other means for the long run. In addition, the use of CO₂ quotas will credit the waste sector and will promote profitable proper waste management.     

The Potential Role for Management of U.S. Public Lands in Greenhouse Gas Mitigation and Climate Policy

Management of forests, rangelands, and wetlands on public lands, including the restoration of degraded lands, has the potential to increase carbon sequestration or reduce greenhouse gas (GHG) emissions beyond what is occurring today. In this paper we discuss several policy options for increasing GHG mitigation on public lands. These range from an extension of current policy by generating supplemental mitigation on public lands in an effort to meet national emissions reduction goals, to full participation in an offsets market by allowing GHG mitigation on public lands to be sold as offsets either by the overseeing agency or by private contractors. To help place these policy options in context, we briefly review the literature on GHG mitigation and public lands to examine the potential for enhanced mitigation on federal and state public lands in the United States. This potential will be tempered by consideration of the tradeoffs with other uses of public lands, the needs for climate change adaptation, and the effects on other ecosystem services.     

Community energy plans in Canadian cities: success and barriers in implementation

Climate change and sustainable development concerns have motivated some municipalities in Canada to develop community energy plans, which focus on energy needs at the local level for the development of efficient, economical and environmental energy systems. Five Canadian cities that were early adopters of community energy planning principles were studied to assess whether implementation has occurred and what barriers have been experienced. The cities achieved success in the implementation of energy management in municipal operations despite barriers in jurisdiction, perception of cost, communication and capacity, but energy management in the community had not been fully implemented and long-term changes were not prevalent. While reductions were made in the greenhouse gas (GHG) emissions produced by municipal operations, the community's overall GHG emissions were not significantly reduced. Long-term impacts on a city's function and growth will be key if community energy planning is to significantly impact community-wide GHG emissions and energy use.     

Structural and technological changes of greenhouse gas emissions during the transition period in Polish industry

We analyzed the patterns of energy use and greenhouse gas (GHG) emissions in Polish industry arising during the transition from a centrally planned economy to a market economy. A method of analyzing industry energy use and GHG emissions is discussed. Using this method, the impact of changes in industrial production value, the share of specific industry branches in the total industrial production, energy intensity, and the mix of the energy carriers in the 1989–1993 period has been analyzed. The last year of the analyzed period shows favorable trends in efficiency and signs of production structure shift to a less energy-intensive one. Economic reform implemented after 1989, which released energy carriers' prices from government control, had important effects on the industrial sector. Energy efficiency and emission intensity trends of 1992–1994 were favorable; if they continue, production will return to 1989 levels with much lower energy consumption and significantly decreased GHG emissions.

Exploring policy strategies for mitigating HFC emissions from refrigeration and air conditioning

The growing demand for cooling throughout the world, possibly increased by global climate change, requires the implementation of policies to mitigate the related greenhouse gas (GHG) emissions from energy and refrigerant use in the refrigeration and air conditioning (RAC) sector. This article aims to contribute to the discussion on strategies to reduce HFC emissions from RAC by looking at their different temporal effects, caused by stock-flow dynamics. From scenario modeling, we find that containment strategies are often most effective in reducing HFC emissions in the short run, whereas phase out strategies have more potential in the long run. Further findings suggest that early and quick implementation of phase out strategies could lead to important reductions in cumulative HFC emissions, because stock build up is prevented. This timing effect is less pronounced for containment strategies. Lastly, emissions from disposal, if unabated, can lead to equally large emissions annually as those from use. Preference for several short-term benefits of containment strategies might lead to sub optimal emission reduction strategies, endangering long term GHG emission reduction.     

Rising to the Kyoto challenge: is the response of Canadian industry adequate?

A major weapon in Canada's CO2-emissions reduction arsenal is reliance on moral suasion and voluntary action. In this regard, the Voluntary Challenge and Registry (VCR) program constitutes a major effort to encourage industrial firms to reduce their greenhouse gas emissions. In this paper, we begin by providing a critical review of Canadian climate change policy and Canada's international commitments. We then investigate the effectiveness of Canadian policies by analyzing a survey of industrial firms, examining factors that determine firms' familiarity with, participation in and commitment to the VCR program, and their stated potential to reduce emissions by 2008-2012 (Kyoto's commitment period). Results indicate that voluntary programs are unlikely to make a significant contribution to emissions reduction, with industrial firms indicating that, on average, they plan to reduce emissions by some 1-2% below their 1990 level under the current policy approach, much lower than Canada's 6% reduction target.     

Estimating local greenhouse gas emissions—A case study on a Portuguese municipality

This paper describes the study that led to the development of a carbon dioxide emissions matrix for the Oeiras municipality, one of the largest Portuguese municipalities, located in the metropolitan area of Lisbon. This matrix takes into account the greenhouse gases (GHG) emissions, due to an increase of electricity demand in buildings as well as solid and liquid wastes treatment, from the domestic and services sectors.Using emission factors that were calculated from the relationship between the electricity produced and amount of treated wastes, the GHG emissions in the Oeiras municipality, were estimated for a time series of 6 years (1998–2003).The obtained results showed that the electricity sector accounts for about 75% of the municipal emissions in 2003. This study was developed in order to obtain tools to base options and actions to be undertaken by local authorities such as energy planning and also public information.     

Carbon, nitrogen balances and greenhouse gas emission during cattle feedlot manure composting

Carbon and N losses reduce the agronomic value of compost and contribute to greenhouse gas (GHG) emissions. This study investigated GHG emissions during composting of straw-bedded manure (SBM) and wood chip-bedded manure (WBM). For SBM, dry matter (DM) loss was 301 kg Mg(-1), total carbon (TC) loss was 174 kg Mg(-1), and total nitrogen (TN) loss was 8.3 kg Mg(-1). These correspond to 30.1% of initial DM, 52.8% of initial TC, and 41.6% of initial TN. For WBM, DM loss was 268 kg Mg(-1), TC loss was 154 kg Mg(-1), and TN loss was 1.40 kg Mg(-1), corresponding to 26.5, 34.5, and 11.8% of initial amounts. Most C was lost as CO2 with CH4 accounting for <6%. However, the net contribution to greenhouse gas emissions was greater for CH4 since it is 21 times more effective at trapping heat than CO2. Nitrous oxide (N2O) emissions were 0.077 kg N Mg(-1) for SBM and 0.084 kg N Mg(-1) for WBM, accounting for 1 to 6% of total N loss. Total GHG emissions as CO2-C equivalent were not significantly different between SBM (368.4 +/- 18.5 kg Mg(-1)) and WBM (349.2 +/- 24.3 kg Mg(-1)). However, emission of 368.4 kg C Mg(-1) (CO2-C equivalent) was greater than the initial TC content (330.5 kg Mg(-1)) of SBM, raising the question of the net benefits of composting on C sequestration. Further study is needed to evaluate the impact of composting on overall GHG emissions and C sequestration and to fully investigate livestock manure management options.
