Seems like a plug for BP who are the other companiesCurrently diesel sold in Australia can contain up to 50 parts per million of sulphur compared to the less than 15ppm that European countries are bound by.
Although it has to be said that companies in Australia, such as BP, are already selling diesel with a maximum of 10 parts per million of sulphur, two years before any Australian legislation requiring them to do so comes into effect.
