Andy,
In the UK we have standards set by IFOAM and the Soil 
Association which determine what is.is not regarded as Organic. 
Yes, they do cover the application of chemicals but they also take 
a wider view and include materials that are regarded as 
sustainable. Peat moss and any other forms of peat are not 
sustainable. Peat 'grows' at the rate of 1mm/year. Most machines 
remove 1m at a time=1000 years of 'growth'. The use of peat is not 
allowed in the organic standards. 

In the UK there are a growing number (sorryn about the pun!) of 
peat substitutes, coir is popular but some even regard that with 
suspicion due the large distance it has to travel to get to the UK. 
There are also some fine sees and potting composts based on 
composted bark but they can be a bit coarse.]

Thats the problem the Scottish peat bogs have been decimated. 
there are not that many left. Very little is burned these days but the 
characteristic smell of burning 'turf' is still very pleasant.
