Transport sector is one of the major oil consuming sectors; it consumes 51% of the final oil consumption (International Energy Agency, 2010). There is a huge need of a sustainable fuel for the transport sector. Current trend of fossil fuel based transport sector only adds to the greenhouse gas crisis more and more. Lots of studies are going on and a lot of emphasis is given to other alternative fuel for transport sector which can provide fuel for a long term option and large scale as well. Biomethane Compressed Natural Gas (CNG) hybrid can be one of the options for transport sector.

The biotechnology approach for methane mitigation technology involves identification of rice cultivars which emit less methane. It also involves the tailoring of plants which translocate less photosynthate to the roots and more to reproductive parts. Rice cultivation is responsible for 10% of GHG emissions from agriculture. In developing countries, the share of rice in GHG emissions from agriculture is even higher, e.g., it was 16% in 1994.
