In this study, carbon sequestration potential via energy tree plantation in the rural wasteland of Assam, India was estimated under two different plantation species scenarios,viz., (i) Acacia nilotica, and (ii) Bambusa tulda. Furthermore, CO2 emission reduction potential in local tea industries by replacing coal with bioenergy available from the energy plantation was also investigated. It was observed that plantation of B. tulda could sequester more carbon than A. nilotica. Both the plantations could generate adequate bioenergy to substitute coal in tea industries. Over a 50-year time period, using bioenergy as a replacement to coal in tea industries could result in significant negative CO2 emission. Compared to A. nilotica, higher emission reduction is achievable from B. tulda bioenergy feedstock. It is also recommended to undertake further study through site-specific data coupled with life-cycle assessment for precise understanding of carbon sequestration potential of bioenergy plantation.
