Dynamic Models of Fixed Capital Stocks and Their Application in Industrial Ecology

NTNU Publications, link to full article

Summary: Industrial assets or fixed capital stocks are at the core of the transition to a low-carbon economy. They represent substantial accumulations of capital, bulk materials, and critical metals. Their lifetime determines the potential for material recycling and how fast they can be replaced by [...]

Multiregional environmental comparison of fossil fuel power generation-Assessment of the contribution of fugitive emissions from conventional and unconventional fossil resources

NTNU Publications, link to full article

In this paper we investigate the influence of fugitive methane emissions from coal, natural gas, and shale gas extraction on the greenhouse gas (GHG) impacts of fossil fuel power generation through its life cycle. A multiregional hybridized life cycle assessment (LCA) model is used to evaluate sever [...]

More caution is needed when using life cycle assessment to determine energy return on investment (EROI)

NTNU Publications, link to full article

Cumulative energy demand (CED) estimates from life cycle assessments (LCAs) are increasingly used to determine energy return on investment (EROI), but the difference in indicators can lead to a misclassification of energy flows in the assessment. The core idea of EROI is to measure the relation of e [...]

Grid infrastructure for renewable power in Europe: The environmental cost

NTNU Publications, link to full article

Climate mitigation policies in Europe call for an extensive build-up of renewable power, which will increase from 320GW in 2012 to 536GW by 2020. The renewable expansion will mainly consist of the installation of new wind and solar power plants, which require additional transmission lines. The Europ [...]

Life cycle assessment of an offshore grid interconnecting wind farms and customers across the North Sea

NTNU Publications, link to full article

Purpose: This study aims to contribute to an improved understanding of the environmental implications of offshore power grid and wind power development pathways. To achieve this aim, we present two assessments. First, we investigate the impacts of a North Sea power grid enabling enhanced trade and i [...]

The "bad labor" footprint: Quantifying the social impacts of globalization

NTNU Publications, link to full article

The extent to what bad labor conditions across the globe are associated with international trade is unknown. Here, we quantify the bad labor conditions associated with consumption in seven world regions, the "bad labor" footprint. In particular, we analyze how much occupational health damage, vulner [...]

EFFECTS OF SECTOR AGGREGATION ON CO<inf>2</inf> MULTIPLIERS IN MULTIREGIONAL INPUT-OUTPUT ANALYSES

NTNU Publications, link to full article

The past few years have seen the emergence of several global multiregional input-output (MRIO) databases. Due to the cost and complexity of developing such extensive tables, industry sectors are generally represented at a rather aggregate level. Currently, one of the most important applications of i [...]

A global environmental assessment of electricity generation technologies with low greenhouse gas emissions

NTNU Publications, link to full article

Limiting climate change by stabilizing the global temperature requires the near complete phase-out of conventional fossil fuel power generation and its replacement through technologies with low greenhouse gas emissions, such as renewable energy, nuclear power, and fossil fuel power plants with CO 2 [...]

Ecological footprint of nations: Comparison of process analysis, and standard and hybrid multiregional input-output analysis

NTNU Publications, link to full article

The ecological footprint (EF) is an indicator of human requirements on bio-productive land, an essential but limited resource, which use is related to environmental burden. In this article, we compare three methods for calculating national EF: a) the process analysis represented by Global Footprint [...]

Addressing biogenic greenhouse gas emissions from hydropower in LCA

NTNU Publications, link to full article

The ability of hydropower to contribute to climate change mitigation is sometimes questioned, citing emissions of methane and carbon dioxide resulting from the degradation of biogenic carbon in hydropower reservoirs. These emissions are, however, not always addressed in life cycle assessment, leadin [...]
