    Get PDF
    In the context of achieving the targets of the energy economy, Poland’s demand for bioenergy is stimulated by several factors, including the biomass potential of agricultural cultivation. The objective of this article is to indicate perspectives for the sustainable production of energy crops in Poland through the production of total biomass as the main renewable source of energy utilized in the countries of Europe and supported by Directive 2009/28/EC of the European Parliament and of the Council of April 23, 2009 on the Promotion of the Use of Energy from Renewable Sources, currently in force. The most important reasons for promoting the production of plant biomass for energy purposes is the desire to work against climate change and reduce the emission of greenhouse gasses. This article indicates the significant role of Life Cycle Assessment (LCA) in biofuels and their production. Note is also taken of agro- climatic and soil conditions for the production of biomass in Poland as well as the economic aspects using the Agricultural Production Space Valuation Ratio (APSVR).Zapotrzebowanie w Polsce na bioenergię w kontekście realizacji celów gospodarki energetycznej jest stymulowane przez szereg czynników, w tym potencjał biomasy pochodzący z upraw rolniczych. Celem artykułu jest wskazanie na perspektywę zrównoważonej produkcji roślin energetycznych w Polsce poprzez produkcję całkowitej biomasy jako głównego odnawialnego źródła energii wykorzystywanego w krajach Europy, a wspieranego przez obecnie obowiązującą Dyrektywę Parlamentu Europejskiego i Rady 2009/28/WE z dnia 23 kwietnia 2009 r. w sprawie promowania stosowania energii ze źródeł odnawialnych (OŹE). Najistotniejszymi powodami promowania produkcji biomasy roślinnej na cele energetyczne jest chęć przeciwdziałania zmianom klimatycznym i redukcja emisji gazów cieplarnianych. W artykule wskazano na znaczną rolę analizy LCA (Life Cycle Assessment) dla biopaliw i ich produkcji. Zwrócono uwagę na warunki agroklimatyczne i glebowe uwarunkowania produkcji biomasy w Polsce oraz ekonomiczny aspekt jakim jest wskaźnik waloryzacji rolniczej przestrzeni produkcyjnej (WWRPP)

    The valuation tool user guide: monetizing Cradle to Cradle®

    Get PDF
    This User Guide outlines the object, scope and expected deliverables from the Valuation Tool component of the Cradle to Cradle ® C2C BIZZ project. It describes the compendium of subtools that have been developed comprising: i) overview of funding tools; ii) C2C investment appraisal tool; and iii) C2C value indexing tool. The underpinning methodologies, as well as their inherent strengths and limitations are also described. The C2C BIZZ project as a whole aims specifically to promote and enhance the implementation of C2C methods in business site development within North Western Europe (NWE) (PAD, p.14). It is intended to infuse C2C notions into conventional site development, restructuring and management. The primary focus of the project is on planning, building and managing of business sites with C2C credentials (PAD, p.18) using sites in Lille Metropole (La Lainiere), London (London Sustainable Industries Park) and Luxemburg (Ecoparc Windhof) as experimental fields. C2C BIZZ is not concerned with the internal operations and activities of occupiers or users of the developed site. Accordingly, the scope of the valuation tool is confined to the planning, building and management of C2C sites. The deliverable from this component is a compendium of subtools (see Figure 1 below) that may be used to analyse the financial performance of C2C credentials in business sites to aid the making of a business case for such developments and evaluating the financial incentives for particular C2C site development projects. This entire work is premised on the argument that the wider adoption of C2C principles within the built environment depends on the rate of uptake by the private sector. The private sector, being profit driven, are likely to engage in C2C site development if they are convinced of its capacity to contribute to their business goals which ultimately is a return on their investment. The tool development described in this document attempts to provide a framework for collating an evidence base that can assist in articulating the business case for C2C in business site developments

    Tourists’ Satisfaction Vs. Residents’ Quality of Life in Medium Sized European Cities: A Conjoint Analysis Approach for Cultural Tourism’s Impact Assessment

    Get PDF
    This paper discusses the use of conjoint analysis to assess the non market impacts of tourism presence in small and medium sized European cities. It presents the methodological approach developed to this purpose within the EU funded project PICTURE (Pro-active management of the Impact of Cultural Tourism upon Urban Resources and Economies) and its application to the case of the city of Syracuse, Italy. Tourism is one of Europe’s largest economic sectors and features among the largest key industries of the 21st century and cultural tourism is one of the forms of tourism that is expected to witness the most important growth in the future. Sustainable cultural tourism strategies have the potential to assist the conservation of local identities, embedded in their respective cultural heritage, while supporting economic growth. However, tourism in cultural sites can also bring negative impacts, which need to be analyzed and assessed. Economic valuation can support decision making in this sector. This paper first discusses to what extent is possible to value in economic terms the positive and negative externalities brought by cultural tourism to heritage destinations, and which are the currently available valuation techniques. Then it focuses on how to manage destinations in a way to limit negative impacts whilst spreading the positive ones in the region. Then it reports the results of a conjoint analysis study on the city of Syracuse, Italy, carried out on a sample of residents and tourists. In particular it looks at the marginal utility associated to attributes interpreting the carrying capacity of the site. Finally, the paper focuses on the potential and limitations of conjoint analysis studies for the above purposes. Conjoint analysis is a non market valuation technique frequently used to place a value on a good. It is a stated-preference method, in the sense that it asks individuals what they would do under hypothetical circumstances, rather than observing actual behaviors on marketplaces, simulating a hypothetical market and analysing stated preferences rather than observing actual market behaviour. In a typical conjoint analysis choice individuals are asked to choose among alternative variants of a good described by a number of attributes. The alternatives differ from one another in the levels taken by two or more of the attributes. The technique assumes the choice between the alternatives is driven by the respondent’s underlying utility. Conjoint choice experiments were initially developed by Louviere and Hensher (1982) and Louviere and Woodworth (1983). Conjoint choice experiments have been widely used to value environmental and natural resources, and more recently cultural heritage. Previous research seems to confirm that the technique is flexible enough and can be successfully adapted to the assessment of policy strategies. The paper discusses the steps that should be considered when developing a conjoint choice experiment for similar purposes.

    Assessing the time-sensitive impacts of energy efficiency and flexibility in the US building sector

    The building sector consumes 75% of US electricity, offering substantial energy, cost, and CO2 emissions savings potential. New technologies enable buildings to flexibly manage electric loads across different times of day and season in support of a low-cost, low-carbon electric grid. Assessing the value of such technologies requires an understanding of building electric load variability at a higher temporal resolution than is demonstrated in previous studies of US building efficiency potential. We adapt Scout, an open-access model of US building energy use, to characterize sub-annual variations in baseline building electricity use, costs, and emissions at the national scale. We apply this baseline in time-sensitive analyses of the energy, cost, and CO2 emissions savings potential of various degrees of energy efficiency and flexibility, finding that efficiency continues to have strong value in a time-sensitive assessment framework while the value of flexibility depends on assumed electricity rates, measure magnitude and duration, and the amount of savings already captured by efficiency

    Impure Public Technologies and Environmental Policy

    Analyses of public goods regularly address the case of pure public goods. However, a large number of (international) public goods exhibit characteristics of different degrees of publicness, i.e. they are impure public goods. In our analysis of transfers helping to overcome the inefficient provision of such goods, we therefore apply the Lancastrian characteristics approach. In contrast to the existing literature, we consider the case of a continuum of impure public goods. We employ the example of international conditional transfers targeting to overcome suboptimal low climate protection efforts by influencing the abatement technology choice of countries.Impure Public Goods, Lancastrian Characteristics Approach, Conditional Transfers, Ancillary Benefits of Climate Policy

    Ecosystem properties and principles of living systems as foundation for sustainable agriculture – Critical reviews of environmental assessment tools, key findings and questions from a course process

    Get PDF
    With increasing demands on limited resources worldwide, there is a growing interest in sustainable patterns of utilisation and production. Ecological agriculture is a response to these concerns. To assess progress and compliance, standard and comprehensive measures of resource requirements, impacts and agro-ecological health are needed. Assessment tools should also be rapid, standardized, userfriendly, meaningful to public policy and applicable to management. Fully considering these requirements confounds the development of integrated methods. Currently, there are many methodologies for monitoring performance, each with its own foundations, assumptions, goals, and outcomes, dependent upon agency agenda or academic orientation. Clearly, a concept of sustainability must address biophysical, ecological, economic, and sociocultural foundations. Assessment indicators and criteria, however, are generally limited, lacking integration, and at times in conflict with one another. A result is that certification criteria, indicators, and assessment methods are not based on a consistent, underlying conceptual framework and often lack a management focus. Ecosystem properties and principles of living systems, including self-organisation, renewal, embeddedness, emergence and commensurate response provide foundation for sustainability assessments and may be appropriate focal points for critical thinking in an evaluation of current methods and standards. A systems framework may also help facilitate a comprehensive approach and promote a context for meaningful discourse. Without holistic accounts, sustainable progress remains an illdefined concept and an elusive goal. Our intent, in the work with this report, was to use systems ecology as a pedagogic basis for learning and discussion to: - Articulate general and common characteristics of living systems. - Identify principles, properties and patterns inherent in natural ecosystems. - Use these findings as foci in a dialogue about attributes of sustainability to: a. develop a model for communicating scientific rationale. b. critically evaluate environmental assessment tools for application in land-use. c. propose appropriate criteria for a comprehensive assessment and expanded definition of ecological land use

    Big Data has significant impact in developing functional smart cities and supporting modern societies. In this paper, we investigate the importance of Big Data in modern life and economy, and discuss challenges arising from Big Data utilization. Different computational intelligence techniques have been considered as tools for Big Data analytics. We also explore the powerful combination of Big Data and Computational Intelligence (CI) and identify a number of areas, where novel applications in real world smart city problems can be developed by utilizing these powerful tools and techniques. We present a case study for intelligent transportation in the context of a smart city, and a novel data modelling methodology based on a biologically inspired universal generative modelling approach called Hierarchical Spatial-Temporal State Machine (HSTSM). We further discuss various implications of policy, protection, valuation and commercialization related to Big Data, its applications and deployment

    Mitigation Strategies and Costs of Climate Protection: The effects of ETC in the hybrid Model MIND

    Get PDF
    MIND is a hybrid model incorporating several energy related sectors in an endogenous growth model of the world economy. This model structure allows a better understanding of the linkages between the energy sectors and the macro-economic environment. We perform a sensitivity analysis and parameter studies to improve the understanding of the economic mechanisms underlying opportunity costs and the optimal mix of mitigation options. Parameters representing technological change that permeates the entire economy have a strong impact on both the opportunity costs of climate protection and on the optimal mitigation strategies, e.g. parameters in the macro-economic environment and in the extraction sector. Sector-specific energy technology parameters change the portfolio of mitigation options but have only modest effects on opportunity costs, e.g. learning rate of the renewable energy technologies. We conclude that feedback loops between the macro-economy and the energy sectors are crucial for the determination of opportunity costs and mitigation strategies.Endogenous technological change, Climate change mitigation costs, Integrated assessment, Growth model, Energy sector, Integrated assessment
