The very extreme figures seem related to 'old' and potentially poorly maintained mower engines, it is also important to note that the pollution figures relate to PAH, not to the whole range of emissions - SOx, NOx, CO2 etc. Still there is clearly a need for a debate about how gardens can be best maintained; getting rid of lawns also brings problems - see Wildlife Gardening forum !

The book I mentioned was first published in 2004. It doesn't say how old the facts are or where the facts even came from, sorry not a good basis for a thread starter - but I found the figures so staggering.
