Achieving carbon neutrality in commercial building developments - Perceptions of the construction industry

The building sector is one of the biggest energy consumers and carbon emitters. The importance of carbon emissions reduction is widely recognised as critical in dealing with rising global climate change concerns. This research focused on carbon emissions reduction in commercial developments. Semi-structured interviews were conducted with selected industry practitioners to identify factors contributing or impeding the achievement of carbon neutral commercial building development. The results showed that the lack of a clear definition of carbon neutral building presents a significant barrier in pursuit of this goal. Key success factors highlighted in this study include: market demand, material selection, facility manager’s knowledge, government support and leadership. In addition, an exemplar project plays a pivotal role in facilitating cultural change in the construction industry. This study provides a useful reference for carbon neutral building developments.     

Influences of landscape and lifestyle on home energy consumption

Rapid urbanization coupled with concerns about global climate change has renewed interest in energy conservation and carbon dioxide emissions reduction. Urban residential energy consumption is a valuable place to start reducing emissions, and urban tree planting programs have been both proposed and utilized as an energy conservation mechanism. Home energy savings associated with urban trees are often quantified using models because of the many complex interactions among variables that can influence home energy use. However, recent empirical analyses have found that energy savings associated with trees may be minimal relative to other important factors like building characteristics and human behaviors. We surveyed 176 residents from four neighborhoods in Raleigh, NC with varying socio-economic characteristics to assess relationships between summer energy usage, tree cover, homeowner behavior, and building characteristics. As hypothesized, we found that building characteristics, demographics, and human behaviors were all significant variables in describing the variability in summertime home energy usage. Although, total percent tree cover 18?m around the home did not affect summertime energy use, the number of trees in the NE and NW quadrants around each household did predict home energy use. These results indicate that planting trees may not be a successful strategy for reducing energy use from the residential sector in the heavily forested Southeast; rather efforts should target conservation and efficiency.     

Carbon Labelling and Low‐income Country Exports: A Review of the Development Issues

This article discusses the carbon accounting and carbon‐labelling schemes being developed to address growing concerns over climate change. Its particular concern is their impact on small stakeholders, especially low‐income countries. The popular belief that trade is by definition problematic is not true; carbon efficiencies elsewhere in the supply chain may more than offset emissions from transportation. Indeed, low‐income countries may offer important opportunities for carbon emission reductions because of their favourable climatic conditions and use of low energy‐intensive production techniques. However, their effective inclusion in labelling schemes will require innovative solutions to provide low‐cost data collection and certification.

Wood energy production,sustainable farming livelihood and multifunctionality in Finland

Climate change and the projected depletion of fossil energy resources pose multiple global challenges. Innovative technologies offer interesting possibilities to achieve more sustainable outcomes in the energy production sector. Local, decentralized alternatives have the potential to sustain livelihoods in rural areas. One example of such a venture has emerged around heating businesses in rural Finland, and is referred to as heat entrepreneurship. Heat entrepreneurship entails a system where a local forest owner, usually a farmer, provides heat to a small community or local building, such as a school. Heat is produced using local forest resources that would otherwise be unutilized. The purpose of this study is to examine heat entrepreneurship as a potential sustainable alternative for energy production and its multifunctionality. The data was collected by interviewing 15 heat entrepreneurs in the area of Central Finland. The study demonstrates how multifunctional farming-related energy production can provide more sustainable livelihoods for farmers by increasing social, economic and environmental sustainability. This is achieved by diversifying farmers' economic options, enhancing rural areas economically, increasing farmers' social networks and well-being and, to some extent, by boosting local environmental capital. However, the study also points to differences among the farmers and sustainability trade-offs, suggesting for the need to better acknowledge the local perceptions in policy-making.     

气候变化政治对海湾国家的影响

海湾地区气候炎热,淡水资源缺乏。长期以来,海湾国家主要依靠能源出口获取大量资金,借此修建海水淡化工厂等各种设施以适应和改善气候环境的影响。近年来,国际社会在应对全球变暖问题的协调合作中,已形成一种处理全球气候变化的政治。气候变化政治要求各国减少能源消耗和降低二氧化碳排放量以缓解全球变暖趋势,从而对海湾国家以能源出口收益来维护生存环境和社会稳定的基本经济模式构成冲击。面对气候变化政治带来的冲击,海湾国家目前的权宜选择只能是继续扩大能源出口,并尽量拖延实施气候变化协议来进行应对。然而,这种做法虽可以暂时保持海湾国家改善环境的努力和维护其经济政治结构稳定,但却难以消除全球气候变化政治今后长期推动能源结构调整和节能减排所带来的压力。     

Sustainable societies in the information age

This article interweaves the ideas of sustainable development, sustainable societies, and the power of advanced information technologies toward developing recommendations for social science research on information technology in society. Worldwide concern has arisen over the potentially catastrophic consequences of global climate and environmental change. As a result, sustainable development (i.e., the simultaneous protection of both the global environment and the global economy) is receiving considerable attention. Necessary for achieving sustainable development are sustainable societies, which are capable of designing, implementing, managing and evaluating long-term environmental programs. This article presents ten characteristics that describe sustainable societies and discusses how information technologies, from wireless personal digital assistants to intelligent agents to multi-media database systems, could support the evolution of sustainable societies. Topics for social science research related to designing and ameliorating the negative consequences of eight hypothetical computer-based systems are presented. Bruce E. Tonn is leader of the policy systems analysis group at Oak Ridge National Laboratory and co-principal investigator of the National Center for Environmental Decision-making Research. His research interests include environmental and energy policy, computers in society, decision making, and futures studies. He is past president of the Social Science Computing Association. His research focuses on planning, assessment and evaluation, energy use and conservation, and education.     

Meeting World Growing Energy Needs the Role of Nuclear Power

The 21st century will face an increased population with limited resources. The latest projection of the United Nations estimates an additional 1.65 billion people by 2030. The rising population should access to all modern services and welfare. Resources demand is expected to increase dramatically in the 21st century, especially in developing countries, where population growth is fast and billions of people nowadays have no access to these services. If no new, strong energy-policy interventions occur, the world’s energy needs will be well over 50% higher in 2030 than today. Fossil fuels will continue to dominate world fuel mix (IEA, International Energy Agency, in World energy outlook 2007, Paris, 2008). The consequent growth in energy-related emissions of carbon-dioxide is noteworthy. The challenge is to reach an energy system allowing this growth and assuring security, reliability, and environmental protection. With worldwide demand for energy expected to more than double by 2030, the need for safe, clean, reliable energy is essential. Much of greenhouse gasses emissions is due to the energy sector. Energy supply, generation and use (and its environmental consequences) is definitely the issue of our times and the coming. All technologies may be complimentary for fitting the demand. Known means exist to cut energy demand and change the fuel mix. In this paper, we will introduce the energy issue and show which role nuclear energy could have in reducing emissions.     

Urban high-resolution fossil fuel CO<Subscript>2</Subscript> emissions quantification and exploration of emission drivers for potential policy applications

Fossil fuel carbon dioxide (FFCO₂) emissions are the largest driver of anthropogenic climate change. Approximately three-quarters of the world’s fossil fuels carbon dioxide emissions are generated in urban areas. We used the Hestia high resolution approach to quantify FFCO₂ for Salt Lake County, Utah, USA and demonstrate the importance of high resolution quantification to urban emissions mitigation policymaking. We focus on the residential and onroad sectors across both urbanized and urbanizing parts of the valley. Stochastic Impact by Regression on Population, Affluence, and Technology (STIRPAT) regression models using sociodemographic data at the census block group level shows that population, per capita income, and building age exhibit positive relationships while household size shows a negative relationship with FFCO₂ emissions. Compact development shows little effect on FFCO₂ emissions in this domain. FFCO₂ emissions in high income block groups is twice as sensitive to income than low income block groups. Emissions are four times as sensitive to household size in low-income versus high-income block groups. These results suggest that policy options targeting personal responsibility or knowledge feedback loops may be the most effective strategies. Examples include utility bill performance comparison or publicly available energy maps identifying high-emitting areas. Within the onroad sector, high emissions density (FFCO₂/km) is associated with primary roads, while high emissions intensity (FFCO₂/VMT) is associated with secondary roads. Opportunities exist for alignment of public transportation extension with remaining high emission road segments, offering a prioritization of new onroad transportation policy in Salt Lake County.     

Green Consumption and Social Change: Debates over Responsibility,Private Action,and Access

Attempting to influence everyday consumer practices is an increasingly popular strategy used to address environmental problems and further social change. This article focuses on exploring the controversial topic of green consumption, a growing area of study that brings together multiple disciplines including environmental sociology and the sociology of consumers and consumption. The article begins with a summary of the literature on green consumption and is then organized around three debates over how green consumption contributes to, or fails to contribute to, social and environmental change. The first debate is over locating responsibility for carbon dioxide emissions, the main contributor to greenhouse gases and climate change. The second debate considers what average people are doing to help address environmental problems. The third debate is about access to green consumption. Should policies work to increase access to greener products and efficient technologies for everyone or does the question of access push aside questions of inequality (race, class, and gender) and sufficiency (how much is enough)? These debates, in different ways, attempt to address the broader question of how social change happens and what we should do to support it.     

Inflation and the misallocation of resources

This paper analyzes the effects of inflation on the resource allocation between the financial sector and the manufacturing sector. We develop a model with heterogeneous workers who can be employed either in the manufacturing sector, which produces a consumption good, or the financial sector, which provides liquidity services. A rise in inflation reduces the demand for labor in the manufacturing sector and increases the demand for financial services. This induces a shift of resources from the manufacturing sector to the financial sector and reduces consumption opportunities. An empirical investigation using 55 countries strongly supports the result that higher inflation increases the relative size of the financial sector.     

Worlds apart,worlds together: converging and diverging frames in climate and energy governance

This paper argues that past research has overlooked how the way problems and solutions are framed contribute to a prevailing gap in the global governance of climate and energy. Empirically, this paper investigates the frames of energy and climate change as expressed in key documents from the International Panel on Climate Change (IPCC) and International Energy Agency (IEA). Partly in contrast to past research, this paper finds (1) that there is a growing similarity in how the IPCC and IEA frame climate and energy; (2) that the IEA has gone from ignoring to acknowledging climate change and the transformation to a low-carbon energy system; and (3) that there is a prevailing difference in emphasis, whereas the IPCC only marginally discuss energy, while the IEA is still mainly talking about energy needs and fossil fuels even if climate change and renewables have entered their agenda.     

The Road Through Paris: Climate Change,Carbon, and the Political Dynamics of Convergence

Abstract

This article tracks the key events that set the stage for the 21st Conference of the Parties to the UN Framework Convention on Climate Change (COP21) in Paris, particularly as they relate to politics of convergence. One side of this coming together is an intersection of issues, where new terrestrial and aquatic carbon sequestration programs have blurred the margins of climate change mitigation and resource grabbing. These programs, enclosing forests, farmlands, and oceans, are likewise fused together in what can be described as an emerging ‘carbon complex’ that is part of the wider blue/green economy. On the reverse side, the clear intersection of issues as witnessed by radical, and historically sectoral, agrarian/social justice movements is causing them to intertwine in resistance. The realm of climate change has proven to be an exceptional space of struggle and countermovement building. Political interactions between movements have become increasingly sophisticated—requiring frameworks that address environmental, agrarian, and oceanic issues at once, as the issues have become ever more complex. Agrarian/social justice movements maintain that their agendas for food sovereignty and climate justice hinge upon exposing fault lines in the system and advocate overall system change. COP21 and its parallel side events were together a landmark moment, but part of a much more involved process, ‘the road through Paris’, along which movements had carved out transnational and local spaces of convergence against the backdrop of a global carbon complex.

Implementation challenges to the adaptive reuse of heritage buildings: Towards the goals of sustainable,low carbon cities

It is well acknowledged that low carbon emissions is one of the key factors contributing to sustainable urban development and effectively tackling climate change. Adaptive reuse of buildings is a form of sustainable urban regeneration, as it extends the building's life and avoids demolition waste, encourages reuses of the embodied energy and also provides significant social and economic benefits to the society. Thus, it embraces the different dimensions of sustainability. However, the debates over which sustainability factors are key, and how to address them all in practice, remain unresolved. This study begins with an intensive literature review of the factors that contribute to the goal of sustainable development in the conservation of built heritage. This is followed by in-depth interviews with practitioners who have participated in adaptive reuse projects in Hong Kong. These interviews confirm the reliability of the shortlisted sustainability factors. More importantly, this paper examines the challenges in incorporating a sustainability framework into adaptive reuse projects. The authors stress that the framework for achieving sustainable, low carbon adaptive reuse should be viewed more holistically, integrating social, economic, environmental, urban and political policies.     

Analysing domestic activity to reduce household energy consumption

This paper presents our reflections on the issue of behavioral change according to energy conservation constraints and on the status of sustainability in the design of ambient interactive systems at home. We point out how ergonomics contributes to the study of human factors underlying energy consumption. Relating to situated cognition and human computer interaction, our approach relies both on the ergonomic evaluation of feedback consumption displays and on the modeling of domestic activities in order to identify household concerns in real settings. We present empirical results to illustrate this global approach. The results of those studies allow the design of interactive systems: informative and pedagogical systems as well as pervasive and adaptive ambient systems. In our approach, sustainability is taken into account as a design criterion, as security could be, whereas the main design purpose is to aid households in their daily life in order to build a "sustainable situation".     

Southern knowledge online? Climate change research discoverability and communication practices

The networked age promises global digital cultures with flattened power relations, given the affordances of information and communication technologies to collapse distance, enable easier cross-country collaborations and create new opportunities for knowledge production and sharing. In the academic domains, indications are that knowledge patterns continue to reflect physically based geopolitical realities – where knowledge from the South is still peripheral while knowledge from the North still dominates in terms of all the conventional metrics. This study explores the potential role of digital affordances to challenge structural Northern bias and generates questions about knowledge production and dissemination in the climate change knowledge domain. It is framed by the field of scholarly communication within an African setting and by the emergent field of climate change which is fraught with debates and contestations, particularly regarding mitigation and adaptation. It draws on Southern theory which interrogates the global dynamics of knowledge production and dissemination. It explores the intersection of the discoverability and visibility of local climate change research methodologically from the outside in, through an experiment of searches for ‘climate change/South Africa’ and from the inside out by reviewing the online presence of one climate change group in a top-ranked African university.     

COP 21 Charades: Spin,Lies and Real Hope in Paris

Abstract

UN Climate talks have become an annual fixture on the global diplomatic calendar since 1995. Some have been praised, others denounced, but the levels of greenhouse gas emissions have risen regardless year-on-year. This essay and eyewitness account argues that the Paris COP 21 talks like its predecessors failed to deliver a meaningful result, judged from either a scientific or social justice point-of-view. However it did reveal the presence of a growing and increasingly sophisticated and powerful climate justice movement that heralds the most hope for a just response to the global climate crisis     

This Changes Nothing: The Paris Agreement to Ignore Reality

Abstract

At the 21st session of the Conference of the Parties to the United Nations Framework Convention on Climate Change held in Paris, France, 30 November to 11 December 2015, an Agreement was reached by the international community including 195 countries. The Agreement has been hailed, by participants and the media, as a major turning point for policy in the struggle to address human-induced climate change. The following is a short critical commentary in which I briefly explain why the Paris Agreement changes nothing. I highlight how the Agreement has been reached by removing almost all substantive issues concerning the causes of human-induced climate change and offers no firm plans of action. Instead of substantive cuts in greenhouse gas (GHG) emissions, as soon as possible, the intentions of the parties promise escalation of damages and treat worst-case scenarios as an acceptable 50:50 chance. The Paris Agreement signifies commitment to sustained industrial growth, risk management over disaster prevention, and future inventions and technology as saviour. The primary commitment of the international community is to maintain the current social and economic system. The result is denial that tackling GHG emissions is incompatible with sustained economic growth. The reality is that Nation States and international corporations are engaged in an unremitting and ongoing expansion of fossil fuel energy exploration, extraction and combustion, and the construction of related infrastructure for production and consumption. The targets and promises of the Paris Agreement bear no relationship to biophysical or social and economic reality.     

Modernity’s dirt: carbon emissions and the technique of life

ABSTRACT

Under colonialism, the concept of dirt was frequently employed ideologically to make judgements about relative worth. In Africa, a particular European cultural idiom or “technique of life” was presented as superior because of its “cleanliness.” This paper is concerned with modernity’s “technique of life” at a particular historical moment when, as a result of environmental crisis, it is suddenly called upon to give an account of itself. I undercut modernity’s claim to cleanliness by suggesting that what it introduces alongside regimes of order and sanitation is a much more globally destructive form of dirt in the form of increasing carbon dioxide levels. The CAIT Climate Data Explorer is a website that compares carbon dioxide emissions across a range of categories. This paper reads three graphs generated by this website as incomplete figures for making visible modernity’s “technique of life.” Realist fiction, read as a supplement to the climate graph records, is able to reinvest some of the abstract categories employed by the climate data tool – transport, fugitive emissions and electricity use – with the details that characterise particular techniques of life and to reveal the way they continue to be defined, at this historical moment, by narratives of development and consumption.
