Germany
Germany hit the milestone of 900 CNG (compressed natural gas) filling stations nationwide in December 2011. Gibgas, an independent consumer group, estimates that 21% of all CNG filling stations in the country offer a natural gas/biomethane mix to varying ratios, and 38 stations offer pure biomethane.

Greece
Greece uses natural gas buses for public transport in Athens. Also the Public Gas Company (DEPA) has a network of 11 stations (as of 2017), under brand "Fisikon", and plans more stations in next 5 years.

Ireland
Bus Éireann Introduced the first NGV (natural gas vehicle) on 17 July 2012. It will operate on the 216 city centre to Mount Oval, Rochestown, route until mid-August on a trial being undertaken in partnership with Ervia. The Eco-city bus is made by MAN.

Italy
Natural gas traction is quite popular in Italy, due to the existence of a capillar distribution network for industrial use since the late 50s and a traditionally high retail price for petrol. As of April 2012 there were about 1173 filling stations, mainly located in the northern regions, while the fleet reached 730,000 CNG vehicles at the end of 2010.

Ukraine
Ukraine's first compressed natural gas refueling station (CNGS) was commissioned in 1937. Today, there is a well-developed CNGS network across the country. Many buses were converted to run on CNG during the 1990s, primarily for economic reasons. The retrofitted cylinders are often visible atop the vehicle's roof and/or underneath the body. Despite their age, these buses remain in service and continue to provide reliable public transport combined with the environmental benefits of CNG.

United Kingdom
CNG buses are beginning to be used in the UK, e.g. by Reading Buses (which  is a bus operator serving the towns of Reading, Bracknell, Newbury, Slough, Windsor, Wokingham, Fleet, Henley-on-Thames and the surrounding areas in the counties of Berkshire, Oxfordshire, and Hampshire).
