ConocoPhillips has significant marketing operations in Europe. In the UK, there are more than 400 branded JET retail sites, which are operated by independent dealers. ConocoPhillips assets on these sites are purely associated with branding. Distribution is via terminals, one of which is owned by ConocoPhillips, using a contracted road tanker fleet.

Other markets served are aviation and marine. JET supplies the United Kingdom's growing secondary airports using owned and shared refuelling tankers and storage. Marine markets are served using contracted vehicles, as is the LPG business.
