Biogas and biomethane: Movement

Gas that rarely crosses borders, though certificates do

What this tab covers How it moves between countries: share of output traded, physical form and transport, the largest exporters and importers, main routes, India's trade, and handling rules in transit.

Measure	Figure
Share traded	almost none crosses borders physically; certificates move instead (indicative)
How it moves	Grid injection where pipelines exist; compressed gas in cascades on trucks (India) or bio-LNG by truck and ship. Low energy density makes long-haul physical trade uneconomic, so it is used near where it is made.
Routes and chokepoints	Local; within the EU, mass-balanced certificates move across the interconnected grid.
India	No imports or exports; CBG is trucked in cascades to CNG stations or injected into city gas networks, and about 304,000 scmd of biogas had been sold under the CBG-CGD scheme by Nov 2025 (Renewable Watch).
Handling in transit	UN1971 methane, compressed (Class 2.1 flammable gas) for CBG cascades; UN1972 for bio-LNG.
