This study applies a partial equilibrium forest sector model to analyse the impacts of biofuel deployment for road transport in the Nordic countries, when alternative use of the biomass resources and transport sector electrification are considered. We foresee a strong electrification of the transport sector, resulting in a demand for biofuels of approximately 2.5 billion L in 2035 and 1 billion L in 2050 in a 100% fossil-free base scenario. The simultaneous increase in demand from pulping industries and biofuel will cause an overall increase in wood use, of which the biofuels share will constitute approximately 20–25%. The utilization of harvest residues will increase more than 300% compared to the current level, since biofuel production will reallocate some of the current raw material used in district heating. Biofuel consumption in road transport will likely reduce after 2040 due to increasing electrification, but it is plausible that the declining domestic demand will be replaced by increasing demand from international biofuel markets in aviation and shipping. The main uncertainties in the scenarios are the future costs and profitability of forest-based biofuel technologies and the public acceptance of the close to 100 TWh of new renewable electricity production needed for the electrification of Nordic road transport.

We examine the financial performance of the forest products industry in the initial phase of the COVID-19 pandemic, employing data for publicly trading companies in the industry globally. We first examine the market investor reaction to the declaration of a pandemic by the World Health Organization (WHO) in March 2020 by conducting an event-study analysis. Then, we analyze medium-term changes in stock returns and their systematic risk by an econometric estimation of the capital asset pricing model. Our event-study analysis of the forest products industry shows that the forestry subsector was impacted more than the paper subsector when the WHO declared the pandemic. The effect was most prominent in North America. We find that the systematic risk for the forestry subsector tended to increase during 2020, until October. Again, this effect was most clear in North America. Conversely, the impact on the paper subsector was more stable.

Sound estimates of future heat and electricity demand with high temporal and spatial resolution are needed for energy system planning, grid design, and evaluating demand-side management options and polices on regional and national levels. In this study, smart meter data on electricity consumption in buildings are combined with cross-sectional building information to model hourly electricity consumption within the household and service sectors on a regional basis in Norway. The same modeling approach is applied to model aggregate hourly district heat consumption in three different consumer groups located in Oslo. A comparison of modeled and metered hourly energy consumption shows that hourly variations and aggregate consumption per county and year are reproduced well by the models. However, for some smaller regions, modeled annual electricity consumption is over- or underestimated by more than 20%. Our results indicate that the presented method is useful for modeling the current and future hourly energy consumption of a regional building stock, but that larger and more detailed training datasets are required to improve the models, and more detailed building stock statistics on regional level are needed to generate useful estimates on aggregate regional energy consumption.

The forest-based sectors are in a period of significant transition due to climate change mitigation efforts, changes in forest products demand and other external mega-trends. This study applies a three-step Delphi process to identify the main drivers and formulate possible scenarios for the development of the Norwegian forest sector towards 2040. The impacts of these scenarios are analyzed with a partial equilibrium forest sector model covering the Nordic countries. Experts in the sectors expected a further decrease in demand for printing and writing paper, but a significant increase in wood-based biofuel production. A “conservative” scenario, with a prolongation of current trends and no wood-based biofuel production, leads to declining wood prices but still slightly increased harvest levels in the Nordic countries—especially in Norway, due to increased timber volumes available for harvest. In a “green” scenario, the production of wood-based biofuels and new forest products increased, leading to higher wood prices from the end of the next decade. This will further decrease the production of printing paper.
