Miljö- och arbetsmiljötillsyn i små företag. En inledande studie
- 2005
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Studiens övergripande mål är att ta fram ett underlag för fortsatt diskussion om lagar, föreskrifter och tillsyn på miljö- och arbetsmiljöområdet i småföretag. Detta inkluderar att identifiera förslag som dels kan underlätta lagefterlevnaden på miljö- och arbetsmiljöområdet och dels kan undanröja konkurrens-hinder till följd av lagstiftning. Ett annat viktigt mål är att identifiera förbättringsområden inom vilka tillsyn och lagefterlevnad kan förenklas utan försämrad arbetsmiljö/större miljöpåverkan. Studien är kvalitativ med syftet att öka förståelsen för hur lagefterlevnad och tillsyn i små företag funge-rar inom områdena miljö och arbetsmiljö. Olika aktörers perspektiv lyfts fram i studien och statistik över omfattningen av tillsyn redovisas. Djupintervjuer har gjorts med 13 företag och 14 tillsynspersoner från länsstyrelser, kommuner och Arbetsmiljöverket. Studiens företag är positivt inställda till tillsynsbesök. Tillsynspersonernas polisiära roll har tonats ned över tid och balanseras av insatser för att motivera företagen. Företagen upplever ett stöd från tillsyns-personerna att leva upp till lagkraven. Företagen uppfattar tillsynen som en slags besiktning som 'godkänner' att deras arbetsmiljö- respek-tive miljöarbete uppfyller alla gällande lagkrav. I själva verket gör tillsynspersonerna ett urval av vad de ska inspektera vilket inte fråntar företagen något ansvar för att själva kontrollera lagefterlevnad. Lag-stiftningen går mer och mer mot egen kontroll av lagefterlevnad, både inom arbetsmiljö och miljö. Denna typ av regler är inget som uppskattas av studiens små företag. Tillfrågade företag förutsätter att tillsynen är konkurrensneutral men det finns exempel på motsatsen.

Bringing economic opportunity into line with environmental influence : A discussion on the Coase theorem and the Porter and van der Linde hypothesis
- 2006

Ingår i: Ecological Economics. - : Elsevier BV. - 0921-8009 .- 1873-6106. ; 56:2, s. 209-225

Tidskriftsartikel (refereegranskat)abstract
- Environmental concerns and tightened environmental policy parameters have been associated with the notion of additional costs of compliance rather than with innovation and sustainability. The contrary, has also been suggested, claiming that strict environmental legislation merely serves as a catalyst for firms to retain obvious economic and environmental mutual gains-so called win-wins-laying around waiting to be collected. Such implications can be seen from the Porter and van der Linde writings, heavily criticised by Palmer et al. as being built on faulty examples. This paper supports that conclusion and uses property rights and transactions costs theories to find private incentives to explore the win-wins for those actors who have the largest potentials to diminish the pressure on our environment. By applying the Coase theorem, emphasising transaction costs and property rights, this paper argues that strong public support is needed to create private incentives for exploring economic and environmental win-win innovations. The public support suggested is to (A) extend producer responsibilities-where the same costs which may be neglected by the end consumers will, if transferred to the design owner, be viewed as a production cost-and to (B) enforce environmental public procurement. Both may be combined with a support to (C) actors (such as non-governmental organisations and consumer agencies) positioning themselves as information bridges by informing the consumers. The negative effects of asymmetric information among actors can, thereby, be diminished as well as the low interest to primarily care for the environment among common consumers.

Tidskriftsartikel (refereegranskat)abstract
- We investigate whether mandatory energy performance certificates of existing residential properties contribute to property price premiums after the implementation of the EU directive on the energy performance of buildings in the Swedish private housing market. Analysing mandatory energy performance certificates of the 2009–2010 private housing transactions, we find that energy performance is associated with transaction price in situations when it is conditional on a reference benchmark. We also document property price premiums for energy performance within housing segments built before 1960 and those with a lower transaction price per square metre. Our results suggest that the property market values energy performance, and we make recommendations on which housing segments need policy support to encourage energy improvements.

Environmental accounting dimensions : Pros and cons of trajectory convergence and increased efficiency
- 2005
-
Ingår i: Implementing Environmental Management Accounting. - 1402033710 ; , s. 63-80
-
Konferensbidrag (refereegranskat)abstract
- Three dimensions of physically based environmental accounting are indicated-regional, company and product accounting-these have developed along different paths. In the globalised and highly specialised economy of today, company activities and their services are multinational and are to a decreasing degree to be seen as a subset of regions. Consequently, these accounting practices intersect each other, on three dimensions, from micro to macro levels. Even though they are all based on physical and energy input/output (I/O) analysis the differences in terminology, structure and evaluation methods make it difficult to exchange data and use them efficiently. This paper explores several aspects of these three environmental accounting dimensions such as the control engineering tradition, the lack of adequate data and the resource consuming work as well as incompatibility, overlapping scopes and aims. The conclusion is that the three accounting dimensions are similar in construction in spite of a development in independent paths. The differences are not primarily the three-letter acronyms of the tools but the objectives and control scope used in studies. If adopting a common framework and a global all-dimensional nomenclature there are great potentials for increasing the work efficiency, making the tools towards sustainability more sustainable.

Extra Financial Analysis - EFA: Environmental and financial performances of ABB, Akzo-Nobel and SCA. Picturing the business opportunities and risks associated to stakeholder perceptions and environmental and social prerequisites
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- External assessment of companies' environmental aspects often focus on the existence of strategies, commitments, management systems and reporting of firms that concerns environmental aspects. Instead, in line with extra financial analysis, in order to play a role in decision-making, analysis of environmental aspects should incorporate the influence that stakeholders may have on future revenues of the assessed firm and how well advanced corporate strategies are in meeting these threats, turning them into business opportunities. Thereafter, the environmental information financial analysts' use in their financial analyst reports as well as the relation between environmental and financial performance are illuminated. Three industry sectors, Chemicals, Electrical Equipment and Paper & Forest Products, are specially analysed in this report. Out of almost 4500 analyst reports about 36 percent contain environmental information, but when looking at industry sectors these numbers range from only 3 to up to 79 percent. The type of environmental information that the analysts focus on in their reports are on how firms' products and product portfolios are adopted to Environmental regulations facing customers/markets, Customer demands and Eco-Efficiency. This product perspective is strongly related to discussions of business opportunities of the firm. In fact, a good 77 % of the financial analyst reports containing environmental information dealt with opportunities linked to environmental aspects. To a lower extent, financial analysts write about company specific risk issues like emissions and litigations while their reports is virtually absent from aspects like environmental strategies, policies, management systems, reporting and auditing. The correlation between corporate financial and environmental performances is illuminated through regression analyses. Industry environmental risk is found to be negatively correlated to corporate return on assets - ROA - (in an static model) while (when applying a dynamic model) corporate environmental performance and ROA have a positive correlation in the short term, which can find support by other studies using different data.

Introducing Value Chain Stewardship (VCS)

Tidskriftsartikel (refereegranskat)abstract
- After a decade of international negotiations to limit greenhouse gas (GHG) emissions, a sufficient number of countries have ratified the Kyoto agreement. However, even with this positive development there is a formidable challenge since, according to the World Resource Institute (WRI 2004), For the most part, developed nations have failed to attain the non-binding emission reductions they committed to in the original climate treaty in 1992, Ensuring adherence to the reductions stated in the treaty by these nations may become an immense managerial task, not to mention the enforcement of sanctions. Instead of national emission targets the approach of this paper is to focus on trade within selected industry sectors - i.e. housing and transport - responsible for most of the world's GHG emissions. This paper shows that vehicle manufacturers - the design owners - may use their information advantages to influence customers to focus on other aspects of the vehicle than costs during use. Expanding the environmental responsibility of the design owners to coincide with the area of environmental impacts will convert emissions cost into a production cost. It is indicated in this paper that when applying the estimated costs for GHG emissions to the vehicle user, strong enough incentives are not given to drive technological change, but if the responsibility is allocated to the design owner the very same additional costs will be an incentive for the designer to use its information advantage to innovate away from those emissions-rendering technologies. A value chain stewardship (VCS) is, thus, established.

Research, Development and Demonstration Strategies on Environmental Technology. Suggested foundations for a Formas-Vinnova strategy
- 2007
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this report is to provide information for Formas and Vinnova to utilise in their development of a common strategy for their forthcoming environmentally adopted collaborative program. The structure of this report follows the assignment given by Formas and Vinnova to explore how three different aspects can and should influence the design of their forthcoming program. The three parts of the study, that each could constitute a report of its own, are: Definitions of environmental technology, Development trends in the world's vast latecoming economies and Comparative study on environmental policy-making processes for environmentally adopted solutions and technology transformation. When considering the size of the coming Formas-Vinnova programme for environmental technology the recommendation is to make the programme focused on e.g. technology development or demonstration projects. To gain greatest leverage it is vital to figure out how the programme can fit into the landscape of programs that support environmental technology in Sweden and thereby fill the gaps in support that Swedish environmental technology actors are experiencing today.

What does the Dow Jones Sustainability Group Index really tell Us?
- 2001
-
Ingår i: Paper presented at the Business Strategy and the Environment Conference, September 18-19, 2000 at the University of Leeds.
-
Konferensbidrag (refereegranskat)abstract
- Quite often the Dow Jones Sustainability Group Index (DJSGI), which identifies and keeps tracks on the performance of the sustainable driven companies, is referred to as an evidence of that integration of economic, environmental and social considerations in company strategies and management gives increased shareholder values in return. For instance a search on the Internet for 'Dow Jones Sustainability' resulted in a good 1000 hits, e.g. on WBCSD, Deutche Telekom and US EPA. There are, however, no deeper studies carried out really determining the design of the sustainability index and how the devise affects the outcome. This paper has investigated the structure of the sustainability index and compered it with other sector indexes and funds i.e. 'Dow Jones Global Indexes'. The study shows that the sustainability index, to a higher degree, is focusing on the technology community and somewhat lesser on the financial and industrial sectors then the general Dow Jones index does. Moreover, the largest difference of these two indexes is the asymmetric distribution of company size. The market capitalisation of the sustainable group is found to be 2.5 times larger then corresponding average for the general index. Other comparisons show that technology sector companies and large multinational companies have higher growth of stock value; consequently; legitimate questions arise. Are we comparing Apples and Oranges? What comes first the 'Hen or the Egg'? This paper finally discusses if the DJSGI really steers companies towards sustainability and the problem of sectoralisation

What does the performance of the Dow Jones Sustainability Group Index tell us?

Ingår i: Eco-Management and Auditing. - : Wiley. - 1535-3966 .- 0968-9427 .- 1099-0925. ; 8:3, s. 123-133

Tidskriftsartikel (refereegranskat)abstract
- The Dow Jones Sustainability Group Index (DJSGI) is really a family of indexes used to identify and track the performance of sustainably run companies. When the DJSGI was introduced in September 1999, it was claimed to outperform the more generalized Dow Jones Global Index (DJGI) with respect to market capitalization growth. Corporations, NGOs and governmental agencies often refer to the DJSGI for illustrating that integrating economic, environmental and social factors into the operations and management of a company increases shareholder value and business activity transparency. The DJSGI is also used by global corporations to legitimize the efforts they put into sustainability. However, there have been no studies carried out to date that illuminate the business activity transparency of the DJSGI. This study investigates the structure and transparency of the DJSGI compared with the DJGI. The results of this study show that the DJSGI focuses more on the technology sector than the general DJGI does. The average market capitalization value of companies listed in the DJSGI was found to be two-and-a-half times the corresponding average for those listed in the DJGI. This raises some legitimate questions. Does the superior performance of the DJSGI reflect the greater efforts DJSGI companies put into sustainability, or a dependence on asymmetric distributions in company sectors, world regions or market capitalization? This paper therefore endeavours to illustrate the transparency of the DJSGI.

Ingår i: Corporate Environmental Strategy. ; 8:2, s. 95-97
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The growing interest in applying sustainability criteria to investment observed throughout the industrial world has resulted in the creation of numerous sustainability funds. The Dow Jones Sustainability Group Index DJSGI., which is probably the best-known sustainability index, was presented by Ivo Knoepfel in Issue 8/1 of Corporate Environmental Strategy. In his article, the methodology underlying the DJSGI is said to have had a consistent framework. However, in a recent study we have highlighted some of the major elements upon which the DJSGI is based1, and have found evidence to suggest that there might be other factors, unrelated to sustainability, contributing to the apparently superior market performance of the DJSGI, and which may bring its framework consistency into question 2. This , response attempts to illuminate some of these factors.

On the value of land
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The issue of sustainable development is once again moving the production factor land into the focus of economic theory and practise. There are three production factors, capital, labour and land. Land is a synonym to ecosystems. During the major part of the 20th century land in economic theory has been handled as a peripheral issue. The sustainability context implies a challenge to take land in proper consideration. That means to in an adequate way consider system characteristics that result in complex systems, such as thresholds, resilience, irreversibilities, and interdependencies between systems and system levels. The thesis examineshow land can be understood and handled in the context of a sustainable development,the relations between land and society on a conceptual level and in operative terms,the relations between system levels and between the three sustainability dimensions ecological, economic and social,the importance of agriculture and animal production in a sustainable development. The major findings are that in contexts such as economically profitable and natural resource-efficient milk production; methods to measure sustainability performance of production systems generally; and societal strategies for management of natural resources that support economic and social development within ecological sustainability limits, three “laws” need to be handled appropriate: Liebig’s “Law” of the minimum, Shelford´s “Law” of tolerance, and the “Law” of diminishing return in biological-ecological productions systems.The thesis identifies examples within dairy sciences, systems ecology, and engineering sciences that affect or may affect policies in real world systems from local to global level that can be substantially improved. In order to suggest relevant measures a tool-kit supporting a sustainable development have been generated, integrating contributions from agricultural sciences, systems ecology, economic theory, economic geography, applied environmental sciences and theories of complex systems. The thesis summarises around 30 years of professional experiences mainly within advanced consultancy, during which this tool-kit has been developed and applied. Evaluation of some applications afterwards shows relevance. For some of the examples analysed in the thesis, found weaknesses are such that global food security literally is threatened within one to twenty years.

Enhancing the value of corporate sustainability : An approach for aligning multiple SDGs guides on reporting
- 2022
-
Ingår i: Journal of Cleaner Production. - : Elsevier Science Ltd. - 0959-6526 .- 1879-1786. ; 333
-
Tidskriftsartikel (refereegranskat)abstract
- In the past two decades, there has been ongoing development of corporate sustainability reporting frameworks to increase awareness of sustainability-related issues from various company stakeholders. At the same time, major reporting frameworks dealing with sustainability issues increasingly publish guides to support corporations Sustainability Development Goals (SDGs) commitments. For corporations, it is challenging to use these guides to obtain the highest benefits for fulfilling corporate sustainability targets and provide valuable reporting on these for its stakeholders. This paper aims to provide a structural alignment approach and a robust alignment methodology that corporations can repeatedly use to harmonize the SDGs guides of the Global Reporting Initiative (GRI) and the International Integrated Reporting Council (IIRC) to satisfy their evolving SDGs reporting challenges. The corporate sustainability assessment and reporting performance of four telecommunication companies on their SDGs commitment and their SDGs reporting challenges are examined to support them with tailor-made guidance established by aligning various SDGs guides of GRI and IIRC. The alignment process is carried out by utilizing the alignment framework and the alignment approach established by the paper. By applying the proposed alignment approach and alignment framework, the paper concludes that corporations can increase their SDGs reporting performance by satisfying their SDGs challenges with the deliverables of the SDGs guides. It adds value to strategic corporate sustainability literature by analyzing the relationship among companies SDGs approaches in the same sector and supporting the various SDGs guides of GRI and IIRC by applying the alignment approach established in this paper.

Bokkapitel (refereegranskat)abstract
- Understanding short-term electricity price forecasting has received considerable attention in recent years. Despite this increased interest, the litera-ture lacks concrete consensus on the best-suited forecasting approach. This study conducts an extensive empirical analysis to evaluate the short-term price forecasting dynamics of different regions in the Swedish electricity market (SEM). We utilise several forecasting approaches ranging from standard conditional volatility models to wavelet-based forecasting. In addition, we perform out-of-sample forecasting and back-testing, and evaluate the performance of these models. Our empirical analysis indicates that the ARMA-GARCH model with the Student’s t-distribution signifi-cantly outperforms other frameworks. Wavelet-based forecasting is only performed based on the mean absolute percent error (MAPE). Our results of the robust fore-casting methods can display the importance of proper forecasting process design, policy implications for market efficiency, and predictability in SEM.

Does energy efficiency matter for prices of tenant-owned apartments?
- 2022
-
Ingår i: Environmental Science and Pollution Research. - : Springer Heidelberg. - 0944-1344 .- 1614-7499. ; 29, s. 66793-66807
-
Tidskriftsartikel (refereegranskat)abstract
- In this study, we use Energy Performance Certificate (EPC) information to investigate the effect of energy efficiency on the selling price of Swedish tenant-owned apartments. While there is a large body of literature on how energy efficiency affects the sales price of single-family houses, none has exclusively focused on tenant-owned apartments. For owners of tenant-owned apartments in Sweden, heating is for a large share included in the monthly fee paid to the tenant association, which usually does not change on a short-term basis. This raises the question whether homebuyers incentives for acquiring energy-efficient tenant-owned apartments are large enough to be capitalized into the prices. By hedonic models and matching methods, we found mixed results. In our most optimistic scenarios, tenant-owned apartments enclosed in energy-efficient buildings are sold with a premium of approximately 0.8 to 1.2% compared to apartments in non-efficient buildings. The results in this study are not robust to all model specifications and vary across regions. In comparison with recent studies using data for single-family houses in Sweden, our detected capitalization is smaller. Our results highlight a need for targeted measures if EPCs are to be fully capitalized in prices for all dwelling types in which buyers have different economic incentives for reducing their energy consumption.

Management of Sustainability Issues in Industry - A stakeholder perspective
- 2006
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The society and stakeholder demands on corporate handling of social and environmental issues have increased substantially during the last decade which has resulted in vast resources spent on developing and implementing management systems and tools for sustainability issues. An important question to consider is consequently how companies as well as their stakeholders perceive the economic, environmental and social benefits from using these systems and tools in companies. The main findings of the study is that most stakeholder groups perceive that the use of systems and tools for managing sustainability issues result in higher environmental and social performance for the company and its products but it is not likely that the economic performance of the company automatically improves by taking these actions. The main conclusion of the study is that the core of corporate strategies, management and product assessments of sustainability issues should be to deal with how environmental and social aspects influence company revenues and future market shares

Hydrogen production in the Swedish power sector: Considering operational volatilities and long-term uncertainties
- 2021
-
Ingår i: Energy Policy. - : ELSEVIER SCI LTD. - 0301-4215 .- 1873-6777. ; 148
-
Tidskriftsartikel (refereegranskat)abstract
- With more renewables on the Swedish electricity market, while decommissioning nuclear power plants, electricity supply increasingly fluctuates and electricity prices are more volatile. There is, hence, a need for securing the electricity supply before energy storage solutions become widespread. Electricity price fluctuations, moreover, affect operating income of nuclear power plants due to their inherent operational inflexibility. Since the anticipated new applications of hydrogen in fuel cell vehicles and steel production, producing hydrogen has become a potential source of income, particularly when there is a surplus supply of electricity at low prices. The feasibility of investing in hydrogen production was investigated in a nuclear power plant, applying Swedish energy policy as background. The analysis applies a system dynamics approach incorporating the stochastic feature of electricity supply and prices. The study revealed that hydrogen production brings alternative opportunities for large-scale electricity production facilities in Sweden. Factors such as hydrogen price will be influential and require in-depth investigation. This study provides guidelines for power sector policymakers and managers who plan to engage in hydrogen production for industrial applications. Although this study was focused upon nuclear power sources, it can be extended to hydrogen production from renewable energy sources such as wind and solar.

Levelized cost of hydrogen for refueling stations with solar PV and wind in Sweden : On-grid or off-grid?
- 2022
-
Ingår i: Energy. - : Pergamon-Elsevier Science Ltd. - 0360-5442 .- 1873-6785. ; 241
-
Tidskriftsartikel (refereegranskat)abstract
- The European Union expects that hydrogen will play a vital role in future energy systems. Fuel cell electric vehicles currently present a key development path for electrification of the transport sector, which requires infrastructure investments of hydrogen refueling stations, preferably powered by renewables such as solar and wind energy. The economic feasibility of refueling stations depends on geographical locations. This study introduces a model to identify the key cost components of renewable hydrogen for refueling stations, and simulates the performance using solar radiation, wind speed, and electricity price data in a selection of Swedish cities. The study demonstrates the importance of integrating the electricity grid in green hydrogen production. Wind speed is crucial in reducing the cost, whereas solar radiation has less influence. In addition, a combination of solar and wind brings better performance in an off-grid scenario. The most encouraging finding is the cost of 35-72 SEK/kg (3.5-7.2 V/kg), which is competitive with reported costs in other EUcountries, especially since this cost excludes any government support scheme. The study provides a reference for investors and policy makers foreseeing the industrial landscape for hydrogen energy development. (c) 2021 The Authors. Published by Elsevier Ltd.
