The objective of this paper is to investigate the determinants of the adoption of green public procurement (GPP) practices at the local authority level. A conceptual contribution of the paper is an analytical framework, which acknowledges that the adoption of green criteria in tenders should be modelled as a conditionally independent decision from the decision to rely on GPP strategies (guidelines). This approach can help provide novel insights into how various political, organizational, and individual characteristics influence GPP. The paper provides an empirical illustration by concentrating on the role of organizational size. This analysis is based on survey responses from civil servants representing 140 Swedish municipalities. The results are based on the bivariate ordered probit estimator and suggest that large municipalities are more likely to rely on GPP strategies but also less prone to adopt green criteria in tenders when controlling for the presence of such strategies. In large organizations, the centralization of the procurement implies efficiency gains, but it will often be accompanied with longer organizational distances between the procuring and the environmental departments. The paper also highlights the wider implications of the proposed framework, including how future research on GPP practices could approach the role of various political and individual factors.

The purpose of this paper is to investigate the relationship between green industrial policies and domestic biofuel production among OECD countries. The analysis builds on a data set including 24 OECD countries over the time period 2000–2016. This panel is estimated using a variant of the so-called Poisson pseudo-maximum-likelihood model and includes the mix of demand-pull (biofuel blending mandates) and technology-push policies (government R&D), as well as the interaction between these two types of instruments. The results suggest a positive relationship between blending mandates and domestic biofuel production. Thus, a more stringent blending mandate does not only increase the use of biofuels, but also domestic production (as a share of total fuel use). Government R&D has not, however, induced domestic biofuel industrialization processes. The results even suggest a negative interaction effect between government R&D and blending mandates, in turn implying that these two polices target different technological fields. The blending mandates tend to primarily favor commercialized first-generation biofuels, while government support to biofuel R&D has instead been focused on advanced biofuel technology.

This thesis examines the economics of biofuel development by studying the forest raw material market impacts of increased biofuel production, as well as the role of specific policy incentives. Paper [I] presents an economic assessment of two different developments – both implying an increased demand for forest ecosystem services – and how these could affect the competition for forest raw materials. A Swedish forest sector trade model is updated to a new base year and used to analyze the consequences of: (a) increased bioenergy use in the heat and power sector; and (b) increased forest conservation. A particularly interesting market impact is that bioenergy promotion and forest conservation tend to have opposite effects on forest industry by-product prices. Furthermore, combining the two scenarios mitigates the forest industry by-product price increase compared to the case where only the bioenergy-promoting scenario is implemented. In other words, the heat and power sector is less negatively affected in terms of increased feedstock prices if a bioenergy demand increase is accompanied by increased forest conservation. Paper [2] explores the forest product market impacts of increased domestic second-generation (2G) biofuel production in Sweden. Changes in forest raw material prices and resource allocation are assessed using a forest sector trade model, which has been extended with a 2G biofuel module to address such production. The simulation results show increasing forest industry by-product prices, e.g., displaying that increased 2G biofuel production leads to a more intense raw material competition. The higher feedstock prices make the use of forest biomass in the heat and power sector less profitable. Still, we find little evidence of substitution of fossil fuels for by-products. There is also evidence of synergy effects in that the higher by-product prices spur sawmills to produce more sawn wood, something which in turn induces forest owners to increase harvest levels. Paper [3] presents and demonstrates a conceptual interdisciplinary framework that can constitute the basis for evaluations of the full supply-chain performance of various biorefinery concepts. The framework involves soft-linking a bottom-up and a top-down model; it considers the competition for biomass across sectors, assumes exogenous end-use product demand, and incorporates various geographical and technical constraints. We demonstrate this framework empirically by modelling the case of a sawmill-integrated biorefinery, which produces liquefied biomethane from forest industry residues. This case shows, among other things, the importance of acknowledging price change responses when evaluating supply chains. Paper [4] studies the relationship between green industrial policies and domestic biofuel production among 24 OECD countries over the period 2000-2016. This panel is estimated using a variant of the so-called Poisson pseudo-maximum-likelihood model, and incorporates the mix of demand-pull (biofuel blending mandates) and technology-push policies (government R&D), as well as the interaction between these two types of instruments. The results suggest that a more stringent blending mandate tends not only to increase the use of biofuels, but also domestic production. Government R&D has not, however, induced domestic biofuel industrialization processes. The results instead imply that these two polices target different technological fields, in turn leading to no positive interaction between demand-pull and technology-push policies. Finally, Paper [5] investigates the factors that tend to influence Swedish municipalities’ uptake of green public procurement (GPP) practices in the transport sector. The analysis builds on survey responses from civil servants representing 140 Swedish municipalities, complemented by secondary data on, for instance, municipality size. The survey collected information about both individual (e.g., education) and organizational characteristics (e.g., strategies). These data were used to estimate a bivariate probit model, which addresses the endogeneity in the GPP decision-making process. The results indicate that municipality size increases the likelihood of adopting a GPP strategy but decreases the likelihood for GPP uptake. This suggests that larger municipalities benefit from more resources (e.g., staff), but suffer from a larger organizational distance between the procuring and environmental departments. Finally, the results lend meagre support to the street-level bureaucracy hypothesis, i.e., that individual characteristics influence the uptake of GPP.

This paper presents an economic assessment of two different policies – both implying an increased demand for forest ecosystem services – and how these could affect the competition for forest raw materials. A forest sector trade model is updated to a new base year (2016), and then employed to analyze the consequences of a more intense use of bioenergy and increased forest conservation in Sweden. These scenarios are assessed individually and in combination. A particularly interesting market impact is that bioenergy promotion and forest conservation tend to have opposite effects on forest industry by-product prices. Moreover, combining the two policies mitigates the forest industry by-product price increase compared to the case where only the bioenergy-promoting policy is implemented. Namely, the energy using sector (heat and power) is less negatively affected in terms of increased feedstock prices if bioenergy demand targets are accompanied by increased forest conservation. This effect is due to increasing pulpwood prices, which reduces pulp, paper and board production, and in turn mitigates the competition for the associated by-products. Overall, the paper illustrates the complexity of the forest raw material market, and the importance of considering demand and supply responses within and between sectors in energy and forest policy decision-making.

Biofuels and biochemicals play significant roles in the transition towards a fossil-free society. However, large-scale biorefineries are not yet cost-competitive with their fossil-fuel counterparts, and it is important to identify biorefinery concepts with high economic performance. For evaluating early-stage biorefinery concepts, one needs to consider not only the technical performance and process costs but also the economic performance of the full supply chain and the impacts on feedstock and product markets. This article presents and demonstrates a conceptual interdisciplinary framework that can constitute the basis for evaluations of the full supply-chain performance of biorefinery concepts. This framework considers the competition for biomass across sectors, assumes exogenous end-use product demand, and incorporates various geographical and technical constraints. The framework is demonstrated empirically through a case study of a sawmill-integrated biorefinery producing liquefied biomethane from forestry and forest industry residues. The case study results illustrate that acknowledging biomass market effects in the supply chain evaluation implies changes in both biomass prices and the allocation of biomass across sectors. The proposed framework should facilitate the identification of biorefinery concepts with a high economic performance which are robust to feedstock price changes caused by the increase in biomass demand.

Large-scale implementation of forest-based biofuel production will have an impact on biomass prices, something which in turn will affect biofuel production costs. The profitability of emerging biofuel production technologies is usually assessed using techno-economic or market approaches. While techno-economic approaches have a detailed description of technologies within plant-level or supply chain system boundaries, they build on exogenously given static biomass prices. Conversely, market approaches have a consistent description of the economic system including market interactions for prices within local or national boundaries, but they generally lack technological depth. This paper combines these two approaches using an iterative framework for a case study optimising the production cost of liquefied biomethane (LBG) using different configurations of sawmill-integrated biomass gasification.

Cost estimates are developed using system boundaries surrounding a LBG production plant, and the Swedish national borders, reflecting the plant-owner and policymaker perspectives, respectively. The results show that different plant configurations are favoured depending on the choice between minimising the biofuel production cost for the plant-owner or for the policymaker. Market dynamics simulated by the iterative procedure show that a direct policy support of 36–56 EUR/MWh would be needed to sustain large-scale LBG production, which is 12–31% higher than the necessary policy support estimated based on static biomass prices.

In order to reach the renewable energy policy targets in the transport sector, biofuels from forest raw materials (e.g., harvesting residues) can play an important role. However, these raw materials are currently used in both the heat and power (HP) sector and the traditional forest industries. It is essential to understand how these sectors would be affected by an increased penetration of second generation (2G) biofuels. This study investigates price development and resource allocation in the Swedish forest raw materials market in the presence of 5–30 TWh of 2G biofuel production. Sweden is an interesting case study due to its well-developed forest industries and mature district heating sector, something which makes it a suitable country for future 2G biofuel production. A national partial equilibrium model of the forest sector is extended with a 2G biofuel module to address the impacts of such production. The simulation results show increasing forest industry by-product (e.g. sawdust) prices, thus displaying that the 2G biofuel targets lead to increased raw material competition. The higher feedstock prices make the use of forest biomass in the HP sector less profitable, but we find meagre evidence of substitution of fossil fuels for by-products. In this sector, there is instead an increased use of harvesting residues. Fiberboard and particleboard production ceases entirely due to increased input prices. There is also evidence of synergy effects between the sawmill sector and the use of forest raw materials in the HP sector. Higher by-product prices spur sawmills to produce more sawnwood, something that in turn induces forest owners to increase harvest levels. Already in the 5 TWh Bio-SNG scenario, there is an increase in the harvest level, suggesting that this by-product effect kicks in from start.

Growing energy use and greenhouse gas emissions have implied an increased attention to the development of renewable energy sources. Bioenergy from forest biomass is expected to be one of the cornerstones in reaching renewable energy targets, especially in forest-rich countries such as Sweden. However, forest biomass is a limited resource, and an intensified use of bioenergy could affect roundwood and forest products’ markets in several ways. The overall purpose of this thesis is to analyze price formation and resource allocation of forest raw materials in the presence of increased bioenergy demand. The empirical focus is on the competition for wood fibres between bioenergy use and the traditional forest industries, as well as synergy effects between the various sectors using forest raw materials. The methodologic approach is partial equilibrium modeling (forest sector model), and the geographical focus is on Sweden. The thesis comprises three self-contained articles, which all address the above issues.

The first paper presents an economic assessment of two different policies – both implying an increased demand for forest ecosystem services – and how these could affect the competition for forest raw materials. A forest sector trade model is updated to a new base year (2016), and used to analyze the consequences of increased bioenergy use in the heat and power (HP) sector as well as increased forest conservation in Sweden. These overall scenarios are assessed individually and in combination. The results show how various forest raw material-using sectors are affected in terms of price changes and responses in production. A particularly interesting market impact is that bioenergy promotion and forest conservation tend to have opposite effects on forest industry by-product prices. Moreover, combining the two policies mitigates the forest industry by-product price increase compared to the case where only the bioenergy-promoting policy is implemented. In other words, the HP sector is less negatively affected in terms of increased feedstock prices if bioenergy demand target are accompanied by increased forest conservation. This effect is due to increasing pulpwood prices, which reduces pulp, paper and board production, and in turn mitiges the competition for the associated by-products. Overall, the paper illustrates the great complexity of the forest raw material market, and the importance of considering demand and supply responses within and between sectors in energy and forest policy designs.

The second article investigates the forest raw material market effects from introducing second-generation transport biofuel (exemplified by Bio-SNG) production in Sweden. Increases in Bio-SNG demand between 5 and 30 TWh are investigated. The simulation results illustrate increasing forest industry by-product (i.e., sawdust, wood chips and bark) prices, not least in the high-production scenarios (i.e. 20-30 TWh). This suggests that increases in second-generation biofuel productions lead to increased competition for the forest raw materials. The higher feedstock prices make the HP sector less profitable, but very meagre evidence of substitution of fossil fuels for by-products can be found. In this sector, there is instead an increased use of harvesting residues. Fiberboard and particleboard production ceases entirely due to increased input prices. There is also evidence of synergy (“by-product”) effects between the sawmill sector and the use of forest raw materials in the HP sector. Higher by-product prices spur sawmills to produce more sawnwood, something that in turn induces forest owners to increase harvest levels. Already in the 5 TWh Bio-SNG scenario, there is an increase in the harvest level, thus suggesting that the by-product effect kicks in from start.

Biofuels and green chemicals are likely to play significant roles in achieving the transition towards a zero-carbon society. However, large-scale biorefineries are not yet cost-competitive with their fossil-fuel counterparts, and it is therefore important to identify biorefinery concepts with high economic performance in order to achieve widespread deployment in the future. For evaluations of early-stage biorefinery concepts, there is a need to consider not only the technical performance and the process costs, but also the performance of the full supply chain and the impact of its implementation in the feedstock and products markets. The third article presents – and argues for – a conceptual interdisciplinary framework that can form the basis for future evaluations of the full supply-chain performance of various novel biorefinery concepts. This framework considers the competition for biomass feedstocks across sectors, and assumes exogenous end-use product demand and various geographical and technical constraints. It can be used to evaluate the impacts of the introduction of various biorefinery concepts in the biomass markets in terms of feedstock allocations and prices. Policy evaluations, taking into account both engineering constraints and market mechanisms, should also be possible.

Overall, the thesis illustrates the importance of considering the market effects when designing and evaluating forest policies and bioenergy policy targets. The forest industry sector and the bioenergy sector are closely interlinked and can both make or break one another depending on the policy design. The results indicate that for an increased demand of bioenergy, an industrial transformation is to be expected, as well as increased roundwood harvest.

3 PhD projects: Markets and price formulation (LTU, economics); Technologies and value chains (Chalmers) and; Location and industrial change (LTU, energy engineering). The general system perspective has its starting point in the importance of biomass and bioenergy in the transition to a long-run sustainable energy system and to an efficient spatial resource utilization and production with increased value chains. Focus is on biorefineries. A spatial approach will be applied in combination with national energy system modelling in connection with technological development potentials and industrial applications is linked to the feed-stock supply as well as market and policy issues.
