Air Quality

Air quality can be divided into two areas:

• indoor air quality 
• atmospheric air quality

It is well established that both indoor and atmospheric air pollution have significant effects on human health as well as on the health of other living organisms. Pollution also leads to acid rain dissolving buildings at a faster rate than would be the case with better air quality conditions.

While particle pollution itself will sometimes form aerosols and smog and thus contribute to local cooling, the larger effect of pollution, in the sense of greenhouse gas emissions, is global warming. Air pollution has also caused a thinning of the protective ozone layer allowing more of the sun's ultraviolet light to pass through to the Earth's surface and cause damage to humans, animals and plants.

During the last thirty years, Denmark has reduced atmospheric pollution by most substances to less than one fifth of the levels characterizing the late seventies. The improvement has been achieved by increases in efficiency, catalyzation and by applying better filters to flue gases and exhaust pipes. Danish companies and research institutions have the knowledge necessary to make similar improvements in other countries.

Improving air quality is an international issue by its very nature. Improvements made by one country matter little on the global level. Danish companies can help nations around the world meet international regulations and improve air quality everywhere, for everyone.
