Introduction
I am a research scientist with formal training in the natural sciences, which included a Masters of Science degree with major in analytical biochemistry. Through my industrial and academic career I consider myself now a cross-disciplinary research scientist, particularly after my PhD in Planning and Development at Aalborg University where my thesis was "Transport and Industrial Ecology: Problems and Prospects". My aim is to improve the scientific knowledge of environmental impacts of human activities.

In the VW diesel scandal, automakers were found to be cheating with emission data, by e.g., tampering with on-board detection systems. We have calculated changes in the energy use and emissions of carbon dioxide equivalents that would arise through several options open to automakers, to ensure that the emission of nitrogen oxides is kept within the...

Producing electricity by harvesting solar energy in photovoltaic (PV) solar cells can, as we will see, lead to serious unintended consequences. It is the manufacturing of the PV that causes the most evident impacts on health and the environment. The large consumption of water for rinsing wafers between etching steps, creates a subsequent need for w...

As has been shown, the development of renewable energy is connected to a large number of negative, unintended consequences. However, it is critical to also consider the reduction of energy use, as a key issue in this discussion, irrespective of whether the energy is taken from renewable or nonrenewable sources. This was touched upon in Chap. 2, whi...

There are indications that blending biofuels into fossil fuels make the exhaust more toxic, in comparison with exhaust from pure fuels. The basis for this is not known, but research points to the creation of new types of emission components, facilitating easier entry of carcinogens(e.g. PAHs)into lung cells. It is urgent to provide new knowledge of...
