IMO the idea that LA is greener than Cophenhagen is ludicrous. Especially note that Copenhagen has a bike culture, and 1/5 of all trips are taken by bicycle.
A few snips from wiki:
The total length of operational track is 2,667 km, 640 km electrified at 25 kV AC, 946 km double track (2008).[3] 508 km is privately owned and operated. Track is standard gauge.
[edit] Railway links with adjacent countries
Sweden — yes — same gauge — voltage change 25 kV AC/15 kV AC.
Germany — yes —same gauge — voltage change 25 kV AC/15 kV AC.
The Oresund Bridge provides a rail connection with Malmö, Sweden. These trains have a 20-minute schedule, and continue further into Skåne County.
There are railway connections from Hamburg to Copenhagen via:
the old Little Belt Bridge — 1935
the Great Belt rail link with the Western Bridge and the Eastern Tunnel — 1997.
A train ferry opened in 1963 as part of the Vogelfluglinie from Rødby, Denmark to Puttgarden, Germany, providing a direct link from Copenhagen to Lübeck and Hamburg in Germany. Several daytime trains Hamburg–Copenhagen still use this ferry. Night trains and freight trains to and from Germany, however, use the Great Belt connection. When the Fehmarn Belt bridge is constructed (expected completion in 2018), it will greatly shorten the journey time between Copenhagen and Hamburg.
The Copenhagen metro[edit] Local city networks
S-train: A traditional suburban train network in the greater Copenhagen area. S-trains (in Danish: S-tog) are electric trains connecting the city center with the suburbs of Copenhagen. The numerous trains leave at 10 or 20 minute intervals. S-trains run from 05:00 hours (weekdays) (06:00 Sundays) until about 0:30 hours.
[edit] Metro
Copenhagen Metro: An automated driverless rail rapid transit system serving Copenhagen and Frederiksberg, Denmark. The system opened in 2002 and currently has two lines with 22 stations and 21.3 km of track, following the 2007 opening of an extension to Copenhagen Airport.

Motorways in DenmarkMain article: Road traffic in Denmark
Further information: Motorways in Denmark
The road network in 2008 totalled 73,197 km of paved road, including 1,111 km of motorway.[4] Motorways are toll-free except for the Great Belt Bridge joining Zealand and Funen and the Øresund Bridge linking Copenhagen to Malmö in Sweden.
[edit] Electric vehicles
Denmark is in a strong position in terms of integrating fluctuating and unpredictable energy sources such as wind power in the grid. It is this knowledge that Denmark now aims to exploit in the transport sector by focusing on intelligent battery systems (V2G) and plug-in vehicles.[5] [6]
[edit] Bicycle lanes and tracks
Three free city bikes in CopenhagenDanish cities and towns, especially Odense and Copenhagen, are known for catering for bicycle transportation. Nearly one-fifth of all trips in Copenhagen are by bicycle, and for home-to-work commutes, 36 % of all trips are by bicycle. Odense has been named the "bicycle city of the year" because of the great number of bicycle lanes in the city. A complete network of 350 km all-weather serviced lanes exists in the town
