Eco Screening : Framtagning av ett verktyg för kartläggning och utvärdering av produkters miljöbelastning vid ÅF EcoDesign Center

The report describes an ecodesign thesis performed by the author at the ÅF EcoDesign Center. The basic idea of ecodesign is to develop products with a minimized environmental load, without neglecting other significant product aspects such as function and price. During the last couple of years the public interest in environmental friendly products has increased, which has made it possible for companies to make a profit from their investments in ecodesign. To meet the increasing market for ecodesign services ÅF started the ÅF EcoDesign Center, where the company has gathered all of their competence in ecodesign in order to help companies to become greener. The task was to develop a tool for an Eco Screening.

Överviktiga barns fysiska aktivitetsnivå

Throughout the history, the theories which have shaped our cities have varied from time to time. We have gone from a city development characterized by spontaneousness, where commerce and people side by side shared the space, into a function-based planning where people and functions are being increasingly separated. Regardless the forms of planning the city design causes implications for those who live there when the physical environment controls were we live, work and meet. In today's society where `sustainability ' has become a watchword the current community planning needs to be questioned so we, in the best possible way, can meet future changes. Searching for new planning strategies is part of this and in this essay the term `mixed-use´ will be investigated and analyzed in terms of its social aspects.

Studie av miljökonsekvensbeskrivingar till detaljplan : En jämförande analys av fyra MKB

When the local authorities establish a plan for land use planning, they have to judge if the influence on the environment could be of such a grade that they have to make a special Environmental Impact Assessment (EIA), following national laws and EU-directives. The laws for the process in Sweden is set by the Swedish Parliament, with advisory given by the central government authority, the National Board of Housing, Building and Planning, Boverket. For EU, the laws is set by the European Parliament and the Council. The laws and directions for this process have been changed for Sweden in recent years, and the aim of this study was to compare the contents of three different Environmental Impact Assess¬ments to see if there has been any change in appearances and content in later years, as well as to see if different municipalities and authors have effect on the EIAs. According to different studies some of the EIA done are without insufficient focus on main environmental issues in the EIA, or even that some information is missing.

Färden till hållbarhet : en studie kring påverkan och ansvarstagande för en hållbar turismutveckling i utvecklingsländerna

The purpose of this dissertation is to describe and analyse the effects of tourism in developing countries and the attitudes and working methods of Swedish tour operators towards sustainable tourism. We have chosen to use a qualitative research according to a hermeneutical view. We have carried through in-depth interviews with eight tour operators. The theories have been divided into the effects of tourism and sustainable tourism goals which have social, economic and environmental starting points. The empiricism describes the work and activities of the tour operators and compiles the interview material divided into attitudes on tourism effects and responsibilities.

Sammankoppling av fjärrvärmenäten i Nyköping och Oxelösund : miljö- och systemkonsekvenser

District heating covers most of the residential areas and industries in the twoneighbouring Swedish municipalities Nyköping and Oxelösund. In Nyköping,Vattenfall AB Värme produces heat in a bio-fuelled CHP plant. In Oxelösund,waste heat and use of waste gases from the steel production at SSABOxelösund is the basis in the district heating system.This report examines the environmental consequences of a connection betweenthe two district heating systems. A broad system approach is used and the focusis on environmental effects in the system.A system analysis has been performed on the result of simulations of differentheat and electricity production alternatives. The alternatives simulated wereone where Vattenfall Nyköping covers the base load in the joint district heatingsystem and two where the power plant at SSAB Oxelösund supplies the heatbase load.The conclusion in this report is that the consequences of connecting the twodistrict heating systems can be both positive and negative, depending onsystem boundaries and on the environmental focus.

Factors for success in Swedish biogas : a study based on the Swedish agricultural sector

The energy sector of modern time is currently faced with several challenges. These are both production oriented and environmental oriented in nature. The energy of the future is intended to support an increasing demand while at the same time reduce its environmental affection. This stresses a development towards production methods of renewable energy. Among the existing methods, biogas is presented as an attractive alternative.

Psykologiska mekanismer och miljöperspektivet - sambandet mellan attityder och beteendeintentioner inför samhällets miljöpåverkan

Syftet med studien var att pröva vilka psykologiska mekanismer som påverkar sambandet mellan attityder och beteendeintentioner inför miljöpåverkan hos individer i konsumtionssamhället. Hypotesen var att det finns ett miljömedvetande hos människan, men att det är en skillnad mellan attityd och beteendeintention. Även emotioner inför miljöpåverkan hos deltagarna undersöktes, för att fördjupa studien. Undersökningen har gjorts kvantitativt via en webbaserad enkät, genom utskick via Facebook till vuxna individer i Sverige mellan 18-65 år (N=49). Svarsprocenten var 46 procent. Huvudresultatet visar att det finns en oro hos individer inför miljön och framtiden och 94 procent av deltagarna anser att miljöfrågor är viktiga.

Hållbar utveckling i kommunalt beslutsfattande : En studie om integrering och prioritering ur fritidspolitiskt perspektiv

The concept of sustainable development is a challenge that demands cooperation from all levels of society for it to be successful. The focus for this thesis is how politicians within the local councils understand the concept of sustainable development and how they implement it in political decision-making.The basis for the study is a questionnaire that was distributed to 303 local politicians in three municipalities of varying size in Southern Sweden. The study concentrates on departments within the local councils that are directly connected to the Swedish environmental law and the Swedish planning and construction law. One of the primary goals with the aforementioned laws is the achievement of sustainable development within one generation.The outcome of the study was that over half of the local politicians could correctly define sustainable development according to the World Commission on Environment and Development?s (WCED) definition.

Ha?llbar sockerro?rsodling fo?r etanolframsta?llning i Brasilien : Hur slagkraftig a?r dagens ha?llbarhetscertifiering och kan den fo?ra?ndra mark- och vattenpa?verkan fra?n odlingarna?

Climate changes today are mainly caused by anthropogenic activities and the increased emissions of greenhouse gases to the atmosphere and this has raised questions on how to reduce the usage of fossil fuels. Ethanol is a good alternative to conventional gas and has been used in Brazil since the 1970 ?s. In Sweden several newspapers has written about the poor working conditions on many farms thus making the Swedish company SEKAB design a certification for their ethanol to ensure that it can be considered to be a sustainable alternative.Furthermore WWF has developed a certification tool called Bonsucro in cooperation with Coca Cola, Ferrero group, BP and Shell. This is due to the fact that no global certification tool has been available up until now.

Fyra kommuner och två länsstyrelser har studerats genom litteratur och kvalitativa intervjuer med fysisk planerare. Två kommuner har kartlagt översvämningsriskerna, varav en har arbetat med att säkra staden..

Är den hållbara staden möjlig utan en levande landsbygd? : en studie av den miljömässiga hållbarheten i Det flerkärniga Skåne

Stora delar av världen genomgår idag en omfattande urbanisering, där allt fler flyttar från land till stad. Samtidigt ges diskussionen om hållbar utveckling mer och mer relevans och utrymme. Som en följd av rådande urbaniseringstrender tycks resonemang kring miljömässig hållbar utveckling ofta beröra hur de urbana strukturerna ska kunna komma att möta framtidens klimatutmaningar, snarare än att alternativa strukturer lyfts fram som möjliga, mer miljövänliga, alternativ. Denna uppsats syftar till att ge en djupare förståelse för vilken betydelse relationen mellan stad och landsbygd har för en miljömässigt hållbar utveckling. Uppsatsen tar sin utgångspunkt i en beskrivning av och diskussion kring miljömässig hållbarhet (och icke-hållbarhet) i staden respektive på landsbygden. Denna beskrivning och diskussion ligger sedan till grund för en analys av huruvida Region Skåne förhåller sig till de miljömässiga fördelar en stärkt relation mellan stad och landsbygd innebär.

Miljömärkningar och medvetenhet : En studie om unga vuxnas medvetenhet kring miljömärkningar

Dagens samhälle är präglat av materialism och dagens konsumtionsmönster är ohållbara ur miljömässig synpunkt. Konsumtionen skapar därmed miljöproblem och ett viktigt styrmedel för att göra den mer hållbar är miljömärkning. Miljömärkta produkter produceras på ett miljöansvarigt sätt utan kemiska bekämpningsmedel och gödsel som är skadliga för både människa och miljö. Syftet med denna studie var att undersöka den nuvarande medvetenheten kring miljömärkningar hos unga vuxna på Möckelngymnasiet. Metoden för studien var enkätutdelning till skolklasser som går sista året på gymnasiet.

Environmental impact assessment of energy recovery from food waste in Singapore : comparing biogas production to incineration

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
