Growing energy consumption is a global problem. The information and communications technology (ICT) industry is in a critical role as an enabler of energy savings in other sectors. However, the power consumption of the ICT sector also needs to be addressed, to contribute to the overall reduction of power consumption and carbon emissions. A new era...

Finland, Sweden and Norway, have their own geographical and societal characteristics including sparse population, long transportation distances and cold weather. These Nordic countries are also highly dependent on P-imports and have strict regulation of trace elements for recycled fertilizers. Considering the bad state of the Baltic Sea due to P-di...

This study focuses on the lifespan of consumer electronics. The article reviews end-of-life terminology in scientific literature and suggests distinguishing end-of-use and end-of-life stages. The question, when electronics become waste, is approached using the concept of a system called PSSP language, which classifies artefacts based on their attri...

Increasing exploration and exploitation activity in the Arctic Ocean has intensified maritime traffic in the Barents Sea. Due to the sparse population and insufficient oil spill response infrastructure on the extensive Barents Sea shoreline, it is necessary to address the possibility of offshore accidents and study hazards to the local environment...

Circular economy has emerged as a sustainable alternative to the traditional, linear, extract-produce-use-dump economy. The scientific society, practitioners, policymakers, and business sectors are all actively taking part in driving the transition toward circular economy in their own sectors.

A new approach to allocate environmental responsibility, the ‘value added-based responsibility’ allocation, is presented in this article. This metric allocates total environmental pressures occurring along an international supply chain to the participating sectors and countries according to the share of value added they generate within that specifi...

The two main methods used to estimate raw material embodied in imports are life cycle assessment (LCA) and multi-regional input-output (MRIO) models. The key advantage of LCA is its higher product resolution but it relies on global or regional averages, which could bias results. Our outcomes suggest that this obstacle could be avoided for primary g...

For Finland, parti...

Further to Directive 2009/28/EC on the promotion of the use of energy from renewable sources, the share of biofuels in transport should rise to a minimum of 10% in Member States by 2020. In Finland, the goal is set at 20%, and it is estimated that this can be produced entirely in domestic factories, as long as the projects already underway will be...

In using input output models for environmental analysis, lack of data regarding technology of trade partners has been traditionally overcome following the " domestic technology assumption " that is, domestic technical coefficients and loads intensities were used in assessing imports. Nevertheless, this assumption may significantly bias results, rem...
