Carbon dioxide (CO2) is a major greenhouse gas that contributes to Earth’s global warming. Over the past two centuries, its concentration in the atmosphere has greatly increased, mainly because of human activities such as fossil fuel burning. One possible option for reducing CO2 emissions is to store it underground. This technique is called Carbon dioxide Capture and Storage (CCS). Air pollution – be it indoors or outdoors – is a major environmental health concern as it can lead to serious health effects, such as respiratory diseases, including asthma and lung cancer. Much progress has been made in Europe in improving outdoor air quality and limit values have been set for several pollutants. However, indoor air quality also requires attention because this is where we spend most of our time. Electricity is so much a part of our lives, there are electromagnetic fields (EMF) around us most of the time. Overhead power lines, wiring in buildings and electrical appliances generate "Extremely Low Frequency" (ELF) electromagnetic fields.
