Similar things to what was done in America. Lots of regulations. The "Great Smog" of 1952, which resulted in several thousand deaths in a matter of days, spurred action, resulting in the Clean Air Act of 1956 and other legislation. It banned many of the more polluting activities which had been common at the time, use of low grade coal and wood in home heating, use of unfiltered diesel engines on transportation in the city, use of coal in power stations near to the city. Factories and power plants were also moved farther away from the city. Here's an interesting little writeup that has some really fascinating graphs on London pollution: http://www.st-andrews.ac.uk/~dib2/atmos/urban.html http://www.st-andrews.ac.uk/~dib2/atmos/urban.html
