Changes in the external costs of freight surface transport in Spain

This paper studies the external costs of surface freight transport in Spain and finds that a reduction occurred over the past 15 years. The analysis yields two conclusions: trucks have experienced a reduction in external costs, and rail has lower externalities. The external costs of road freight transport decrease between 1993 and 2007 (44%). The external costs of rail freight increase by 12%. During this period, the external costs of road freight related to climate increase by 16%, oppositely than those from air pollution and accidents (51 and 44%). The external costs of rail related to pollutant emissions and climate increase by 4% and 43%. Oppositely, the external costs related to accidents decrease by 27%. Road freight generates eight times the external costs of rail, 2.35 Euro cents per tonne kilometre in 2005 (5.6% accidents, 74.7% air pollution and 19.7% climate) vs. 0.28 (13.4% accidents, 53.9% air pollution and 32.7% climate).

Do charges to freight trucks and trains in the European Union reflect their social marginal costs? Application to the case of Spain

In the last few years, the European Union (EU) has become greatly concerned about the environmental costs of road transport in Europe as a result of the constant growth in the market share of trucks and the steady decline in the market share of railroads. In order to reverse this trend, the EU is promoting the implementation of additional charges for heavy goods vehicles (HGV) on the trunk roads of the EU countries. However, the EU policy is being criticised because it does not address the implementation of charges to internalise the external costs produced by automobiles and other transport modes such as railroad. In this paper, we first describe the evolution of the HGV charging policy in the EU, and then assess its practical implementation across different European countries. Second, and of greater significance, by using the case study of Spain, we evaluate to what extent the current fees on trucks and trains reflect their social marginal costs, and consequently lead to an allocative-efficient outcome. We found that for the average case in Spain the truck industry meets more of the marginal social cost produced by it than does the freight railroad industry. The reason for this lies in the large sums of money paid by truck companies in fuel taxes, and the subsidies that continue to be granted by the government to the railroads.

Integrating environmental and economic life cycle analysis in product development: a material selection case study

Purpose Achieving sustainability by rethinking products, services and strategies is an enormous challenge currently laid upon the economic sector, in which materials selection plays a critical role. In this context, the present work describes an environmental and economic life cycle analysis of a structural product, comparing two possible material alternatives. The product chosen is a storage tank, presently manufactured in stainless steel (SST) or in a glass fibre reinforced polymer composite (CST). The overall goal of the study is to identify environmental and economic strong and weak points related to the life cycle of the two material alternatives. The consequential win-win or trade-off situations will be identified via a Life Cycle Assessment/Life Cycle Costing (LCA/LCC) integrated model. Methods The LCA/LCC integrated model used consists in applying the LCA methodology to the product system, incorporating, in parallel, its results into the LCC study, namely those of the Life Cycle Inventory (LCI) and the Life Cycle Impact Assessment (LCIA). Results In both the SST and CST systems the most significant life cycle phase is the raw materials production, in which the most significant environmental burdens correspond to the Fossil fuels and Respiratory inorganics categories. The LCA/LCC integrated analysis shows that the CST has globally a preferable environmental and economic profile, as its impacts are lower than those of the SST in all life cycle stages. Both the internal and external costs are lower, the former resulting mainly from the composite material being significantly less expensive than stainless steel. This therefore represents a full win-win situation. As a consequence, the study clearly indicates that using a thermoset composite material to manufacture storage tanks is environmentally and economically desirable. However, it was also evident that the environmental performance of the CST could be improved by altering its End-of-Life stage. Conclusions The results of the present work provide enlightening insights into the synergies between the environmental and the economic performance of a structural product made with alternative materials. Further, they provide conclusive evidence to support the integration of environmental and economic life cycle analysis in the product development processes of a manufacturing company, or in some cases even in its procurement practices.

Tourism and urban transport: holding demand pressure under supply constraints

Scholars and local planners are increasingly interested in tourism contribution to economic and social development. To this regard, several European cities lead the world rankings on tourist arrivals, and their governments have promoted tourism activity. Mobility is an essential service for tourists visiting large cities, since it is a crucial factor for their comfort. In addition, it facilitates the spread of benefits across the city. The aim of this study is to determine whether city planners respond to this additional urban transport demand pressure by extending supply services. We use an international database of European cities. Our results confirm that tourism intensity is a demand enhancing factor on urban transport. Contrarily, cities do not seem to address this pressure by increasing service supply. This suggests that tourism exerts a positive externality on public transport since it provides additional funding for these services, but it imposes as well external costs on resident users because of congestion given supply constraints.

Financial and Environmental Impacts of a Dry Port to Facilitate Competitiveness of Two Major Transit Seaports of Finland

Environmental problems and issues have received more and more attention during the last decades. Reasons for this are different increased external costs such as congestion, CO2 emission, noise and accident costs. Transportation sector is the only sector with increasing external costs. The EU will increase its attention in decreasing the external costs of transport. Aim of this research was to find out if a dry port solution could decrease costs of transport, especially external costs. Dry port concept is an intermodal transport system, where inland transport between port and dry port is performed by rail transport instead of traditional road transport. In addition, dry ports offer similar services as ports. Research is conducted by performing a literature review about dry port concept and costs of transport, especially external costs of transport. Financial and environmental impacts of the dry port concept are studied by comparing costs of road and rail transport by cost accounting and with a simulation model. Location of dry port is researched with gravitational models. Results of the literature review are that rail transport is environmentally friendlier mode of transport than road transport. Cost model and simulation model show that if only costs of freight movement are considered, rail transport is more inexpensive transport mode than road transport in terms of internal and external costs. Because of that dry port concept could decrease costs of transport, especially external costs. Results of gravitational models are that city of Kouvola is in a good position to be a dry port. Russian transit traffic through Finland improves location of Kouvola to be a dry port.

Kuljetusmuodoista yhteiskunnalle kohdistuvat kustannukset bulktavaraliikenteessä

Diplomityössä tarkastellaan liikennemuotojen yhteiskunnalle kohdistamia kustannuksia, jotka syntyvät ylläpidosta, investoinneista sekä ulkoisista tekijöistä. Liikenteen hinnoittelussa ei useinkaan huomioida ulkoisia kustannuksia kuten päästöjen, melun sekä onnettomuuksien aiheuttamia kustannuksia, joiden laskentaan ja muodostumiseen tässä diplomityössä kiinnitetään erityisesti huomiota. Työn teoriaosassa selvitetään taustaa liikenteen hinnoittelulle sekä esitetään Suomessa käytössä oleva malli liikenteestä muodostuvien kokonaiskustannuksien huomioimiseksi. Tämän lisäksi vertaillaan ulkoisten kustannuksien laskentaa Suomen ja Euroopan välillä. Empiriaosassa lasketaan yhteiskunnalle kohdistuvat kustannukset kahdessa case esimerkissä. Suomessa liikenteen aiheuttamat kustannukset huomioidaan osana hankearviointeja. Näissä ulkoisten kustannuksien osuus on vähäinen muihin kustannuksiin verrattuna. Kirjallisuusselvityksen sekä empiria osuuden perusteella Suomessa tarvitaan lisäselvitystä ulkoisista kustannuksista, jos halutaan saada niiden arvo vastaamaan paremmin Suomen olosuhteita. Investointi ja ylläpitokustannukset on kohdennettu vain tieliikenteessä ajoneuvosuoritetta kohden. Vastaavaa tietoa ei ole saatavissa muiden tarkasteltujen kuljetusmuotojen osalta.

Liikennebiokaasun tuotannon ja käytön ulkoiset kustannukset Pohjois-Karjalassa

Työn tavoitteena oli selvittää liikennebiokaasuntuotannon ja käytön vaikutus liikenteen ulkoi-siin kustannuksiin Pohjois-Karjalassa. Biokaasua tuotetaan Joensuussa Kuhasalon jäteveden-puhdistamolla sekä Kontiosuon jäteasemalla, Kiteellä biokaasua tuotetaan BioKympin yh-teismädätyslaitoksessa. Lisäksi laskennassa huomioitiin yhden maatilakokoluokan biokaasun-tuotanto. Työssä selvitettiin kaksi skenaariota liikennebiokaasun tuotantomääräksi vuodelle 2015. Liikennebiokaasua voitaisiin tuottaa optimiskenaarion mukaan 3 426 MWh ja maksimi-tuotantoskenaarion mukaan 21 532 MWh. Liikennebiokaasun käytön vaikutukset liikenteen päästöihin laskettiin vuodelle 2015 ja vuo-delle 2020, jolloin liikennebiokaasua käytettäisiin 10 % liikenteen energiantarpeesta Pohjois-Karjalassa. Hiilidioksidipäästöt vähenevät vuoden 2020 tilanteessa samassa suhteessa kuin liikennebiokaasu korvaa fossiilisia polttoaineita. Muista päästöistä merkittävimmät päästövä-hennykset saatiin kun vuoden 2010 dieselautot muutettaisiin biokaasuautoiksi, tällöin hiuk-kaspäästöt alenisivat jopa 18 % vuoden 2010 päästöistä. Lisäksi selvitettiin liikenteen päästöjen pienenemisen vaikutus liikenteen aiheuttamiin ulkoisiin kustannuksiin. Laskettavat ulkoiset kustannukset olivat ilmastonmuutos, pakokaasupäästöt sekä energiariippuvuus. Pakokaasupäästöjen aiheuttamat ulkoiset kustannukset olivat vuonna 2010 noin 7 miljoonaa euroa. Liikennebiokaasua käyttävästä ajoneuvotyypistä riippuen ulkoiset kustannukset laskevat vuoden 2020 tilanteessa 10–16 % vuoden 2010 kustannuksista. Ilmastonmuutoksen ulkoiset kustannukset vuodelle 2010 olivat 9,5 miljoonaa euroa. Biokaasun käytön avulla kustannuksissa voitaisiin säästää 910 000 euroa vuonna 2020. Ener-giariippuvuuden hinta öljynkäytöstä oli vuonna 2010 noin 4,2 miljoonaa euroa ja vuonna 2020 kustannukset voisivat laskea 450 000 euroa.

Landscape gene flow, coexistence and threshold effect: The case of genetically modified herbicide tolerant oilseed rape (Brassica napus)

Globally there have been a number of concerns about the development of genetically modified crops many of which relate to the implications of gene flow at various levels. In Europe these concerns have led the European Union (EU) to promote the concept of 'coexistence' to allow the freedom to plant conventional and genetically modified (GM) varieties but to minimise the presence of transgenic material within conventional crops. Should a premium for non-GM varieties emerge on the market, the presence of transgenes would generate a 'negative externality' to conventional growers. The establishment of maximum tolerance level for the adventitious presence of GM material in conventional crops produces a threshold effect in the external costs. The existing literature suggests that apart from the biological characteristics of the plant under consideration (e.g. self-pollination rates, entomophilous species, anemophilous species, etc.), gene flow at the landscape level is affected by the relative size of the source and sink populations and the spatial arrangement of the fields in the landscape. In this paper, we take genetically modified herbicide tolerant oilseed rape (GM HT OSR) as a model crop. Starting from an individual pollen dispersal function, we develop a spatially explicit numerical model in order to assess the effect of the size of the source/sink populations and the degree of spatial aggregation on the extent of gene flow into conventional OSR varieties under two alternative settings. We find that when the transgene presence in conventional produce is detected at the field level, the external cost will increase with the size of the source area and with the level of spatial disaggregation. on the other hand when the transgene presence is averaged among all conventional fields in the landscape (e.g. because of grain mixing before detection), the external cost will only depend on the relative size of the source area. The model could readily be incorporated into an economic evaluation of policies to regulate adoption of GM HT OSR. (c) 2007 Elsevier B.V. All rights reserved.

Estudo da produção de hidrogênio eletrolítico a partir de fontes eólica, solar e hidrelétrica

Introduces technical, economic and environmentally competitive solutions in the energy market is a great challenge for society. This work examines each of these aspects considering the production of electrolytic hydrogen with energy from wind power, solar and hydropower, in order to ensure an overview of this energy carrier. Initially, an assessment of the technical aspects is made addressing existing electrolysers technologies, its main characteristics and differences. The geographical distribution of wind, solar and hydroelectric potential in Brazil is also mapped, and a configuration scheme of a hydrogen production system is discussed. Subsequently, the economic analysis calculates the cost of investment in the alkaline electrolyser of 60 Nm³ / h, similar to the Brazilian bus powered by hydrogen project, coordinated by EMTU. Since the main input of electrolysis is electricity, is analyzed the latest energy auctions of each primary source and it is calculated the cost of production of the wind, solar and hydropower hydrogen. Postponed to this, are investigated the intrinsic environmental impacts of electricity generation process, proposing a readjustment of an indicator of ecological efficiency for the production of hydrogen. Finally, the work discusses the concept of externalities and demonstrates how the incorporation of external costs can leverage the hydrogen economy. In short, it is evident that the wind and hydroelectric hydrogens are more promising compared to solar hydrogen, whether in the economic aspect, because it achieved lower costs, whether in the environmental aspect, because it reached the highest ecological efficiency

Eco-Management and Audit Scheme (EMAS): An evaluation of success factors in the agricultural sector. The case of Italy's Emilia Romagna region.

Different tools have been used to set up and adopt the model for the fulfillment of the objective of this research. 1. The Model The base model that has been used is the Analytical Hierarchy Process (AHP) adapted with the aim to perform a Benefit Cost Analysis. The AHP developed by Thomas Saaty is a multicriteria decision - making technique which decomposes a complex problem into a hierarchy. It is used to derive ratio scales from both discreet and continuous paired comparisons in multilevel hierarchic structures. These comparisons may be taken from actual measurements or from a fundamental scale that reflects the relative strength of preferences and feelings. 2. Tools and methods 2.1. The Expert Choice Software The software Expert Choice is a tool that allows each operator to easily implement the AHP model in every stage of the problem. 2.2. Personal Interviews to the farms For this research, the farms of the region Emilia Romagna certified EMAS have been detected. Information has been given by EMAS center in Wien. Personal interviews have been carried out to each farm in order to have a complete and realistic judgment of each criteria of the hierarchy. 2.3. Questionnaire A supporting questionnaire has also been delivered and used for the interviews . 3. Elaboration of the data After data collection, the data elaboration has taken place. The software support Expert Choice has been used . 4. Results of the Analysis The result of the figures above (vedere altro documento) gives a series of numbers which are fractions of the unit. This has to be interpreted as the relative contribution of each element to the fulfillment of the relative objective. So calculating the Benefits/costs ratio for each alternative the following will be obtained: Alternative One: Implement EMAS Benefits ratio: 0, 877 Costs ratio: 0, 815 Benfit/Cost ratio: 0,877/0,815=1,08 Alternative Two: Not Implement EMAS Benefits ratio: 0,123 Costs ration: 0,185 Benefit/Cost ratio: 0,123/0,185=0,66 As stated above, the alternative with the highest ratio will be the best solution for the organization. This means that the research carried out and the model implemented suggests that EMAS adoption in the agricultural sector is the best alternative. It has to be noted that the ratio is 1,08 which is a relatively low positive value. This shows the fragility of this conclusion and suggests a careful exam of the benefits and costs for each farm before adopting the scheme. On the other part, the result needs to be taken in consideration by the policy makers in order to enhance their intervention regarding the scheme adoption on the agricultural sector. According to the AHP elaboration of judgments we have the following main considerations on Benefits: - Legal compliance seems to be the most important benefit for the agricultural sector since its rank is 0,471 - The next two most important benefits are Improved internal organization (ranking 0,230) followed by Competitive advantage (ranking 0, 221) mostly due to the sub-element Improved image (ranking 0,743) Finally, even though Incentives are not ranked among the most important elements, the financial ones seem to have been decisive on the decision making process. According to the AHP elaboration of judgments we have the following main considerations on Costs: - External costs seem to be largely more important than the internal ones (ranking 0, 857 over 0,143) suggesting that Emas costs over consultancy and verification remain the biggest obstacle. - The implementation of the EMS is the most challenging element regarding the internal costs (ranking 0,750).

Urban food planning, city logistics and sustainability: the role of the wholesale produce market. The cases of Parma and Bologna food hubs.

At global level, the population is increasingly concentrating in the cities. In Europe, around 75% of the population lives in urban areas and, according to the European Environmental Agency (2010), urban population is foreseen to increase up to 80 % by 2020. At the same time, the quality of life in the cities is declining and urban pollution keeps increasing in terms of carbon dioxide (CO2) emissions, waste, noise, and lack of greenery. Many of European cities struggle to cope with social, economic and environmental problems resulting from pressures such as overcrowding or decline, social inequity, health problems related to food security and pollution. Nowadays local authorities try to solve these problems related to the environmental sustainability through various urban logistics measures, which directly and indirectly affect the urban food supply system, thus an integrated approach including freight transport and food provisioning policies issues is needed. This research centres on the urban food transport system and its impact on the city environmental sustainability. The main question that drives the research analysis is "How the urban food distribution system affects the ecological sustainability in modern cities?" The research analyses the city logistics project for food transport implemented in Parma, Italy, by the wholesale produce market. The case study investigates the renewed role of the wholesale market in the urban food supply chain as commercial and logistic operator, referring to the concept of food hub. Then, a preliminary analysis on the urban food transport for the city of Bologna is presented. The research aims at suggesting a methodological framework to estimate the urban food demand, the urban food supply and to assess the urban food transport performance, in order to identify external costs indicators that help policymakers in evaluating the environmental sustainability of different logistics measures

La razionalizzazione del trasporto merci su strada

Il presente lavoro, senza alcuna pretesa di esaustività, ha inteso ricostruire il quadro normativo relativo alla disciplina dell’autotrasporto merci su strada. In primis, ci si è soffermata sugli aspetti generali del settore, approfondendo, in seguito, la normativa europea e nazionale. Tale excursus, ha permesso di riscontrare i molteplici interventi legislativi susseguitisi in ambito di regolamentazione dell’autotrasporto merci su strada, evidenziando i passaggi più significativi in tema di riordino della disciplina. Si è pertanto proceduto all’analisi del primo importante intervento legislativo del settore, intercorso ad opera della Legge n. 298/1974, disciplinante gli aspetti di natura pubblicistica del settore. Tale provvedimento, ha un apposito Albo Nazionale per gli autotrasportatori di merci per conto terzi, identificando i requisiti necessari per l’accesso al mercato e l’esercizio della professione di autotrasportatore di cose in conto terzi. Importati novità vengono introdotte con il D.lgs. 286/2005, provvedimento che ha portato al raggiungimento del processo di liberalizzazione del mercato. Successivamente si è proceduto a riscontrare l’intensa produzione normativa, posta a regolamentazione del settore, che nella ricerca di un equilibrio tra esigenze di mercato e corretto esercizio dell’attività di autotrasporto, si propone di addivenire al raggiungimento degli obiettivi comunitari di armonizzazione della disciplina e qualificazione del settore dell’autotrasporto. Significativi, in tal senso, i recenti interventi di riforma posti in essere con il “Pacchetto comunitario del 21 ottobre 2009” ( Regolamento (CE) 1071/2009 e Regolamento (CE) 1072/2009. Da ultimo, al fine di verificare le eventuali debolezze del sistema normativo vigente, in relazione al raggiungimento degli obiettivi comunitari suesposti, si è ritenuto di indirizzare la ricerca verso un’attenta valutazione dell’efficienza dei modelli di trasporto merci su strada, verificandone l’impatto in termini di maggior incidenza sui costi esterni derivanti dal trasporto. A tal proposito, particolare attenzione è stata rivolta anche alla disciplina del trasporto in conto proprio.
