Pollution from the chimney of an old building pours out into the atmosphere amongst modern glass buildings in the City of London, London, England, United Kingdom. At street level, busses and traffic passes adding to the emissions, and all adding up to the poor air quality which people are breathing on a daily basis. London is trying to achieve air quality targets. The European Air Quality Index, run by the European Environment Agency EEA and the European Commission, allows users to check the current air quality across Europe’s cities and regions. Environmental groups called for the Government to take urgent steps, including creating and funding clean air zones in pollution hotspots.
