Reducing air pollution caused by traffic and industries and improving indoor climate

Cities worldwide are facing numerous challenges. Among these, we find air pollution, which is currently a global health issue causing premature deaths of millions each year. Air pollution in cities is predominantly caused by transportation and industry. With urbanisation set to increase significantly, the problem will affect even more people in the future if no action is taken.

Reducing air pollution from transportation requires that cities focus on changing the mobility patterns of its citizens by e.g. improving access to public transportation and encouraging the use of electric vehicles. In addition, governments lead the way for their citizens and set demands for limiting air pollution from industries, while encouraging developers and architects to design buildings to improve indoor air quality.

In 2018, Denmark got a new Clean Air Vision focused on doubling Danish exports of clean-air solutions by 2030.

A long-term focus on improved air quality

For many years, Denmark has been focused on developing different clean air technologies and solutions to those sectors that represent a significant source of air pollution, including shipping, industrial production and power plants. Coupled with strict environmental legislation and air quality monitoring, this sector-focus has helped to successfully reduce atmospheric pollution in most areas in Denmark to less than one-fifth of the levels during the late 1970s. Consequently improving the air quality in both urban and rural areas.

Air pollution reduction technology

SO2 and NOx found in smoke or exhaust from power and incineration plants can be cleaned by using catalysts and scrubbers. CO2 emissions can be reduced through Carbon Capture and Storage (CCS), where CO2 is physically removed from flue and waste gases. The CO2 can then be compressed to liquid form and stored in suitable underground locations. In Denmark, the geological conditions for storing CO2 are found in many areas of the country.

Improving air quality everywhere – for everyone

With more than 500 high-tech companies delivering clean air solutions for shipping, power and incineration plants, vehicles and indoor environment, Denmark holds the necessary knowledge to make similar improvements in other countries. As a country, we see great opportunity for mutual benefit in the transfer of knowledge and we aim at turning global air pollution challenges into opportunities for sustainable growth.
