Case Studies

Emulsion Fuels

The three major producers of emulsion fuels, diesel fuel with high water content, encountered significant difficulties in marketing their product within the EU. The problem stemmed from the fact that (1) there was no technical standard for such fuels, with the result that the market demand was being tainted by inferior product, and (2) the individual producers efforts to obtain favorable tax treatment (there are significant environmental benefits to using such fuels as opposed to regular diesel) were hampered by the absence of a common definition. We organized a trade association, European Emulsion Fuels Association (EEMFA), and lobbied the EC. By relying upon an underutilized procedure, the parties sponsored, under the auspices of the EC, a voluntary standard that has since been accepted by the industry. Since the adoption of the standard there has been a significant expansion of the emulsion fuel market.
