Biomass refers to the mass of all living matter in a given area that includes all flora and fauna. There are different methods to measure the biomass. Fossil fuel burning releases CO2 which enters the atmosphere and increase the atmospheric CO2 concentration. According to IPCC report, forest ecosystem would release about 100 billion tonnes of CO2 by the next 50 years. Using forest residues (thinnings and logging slash) for bioenergy is an opportunity to restore forest health, wildfire resiliency, and wildlife habitat. Silvicultural operations to improve forest conditions can help revitalize rural economies while providing renewable energy feedstocks. CO2 storage is an integral part of the carbon capture and storage (CCS) chain, and therefore it is important to quantify the storage potential of geological sites such as coal fields, oil and gas fields, and deep saline water-bearing reservoir rocks. India has joined a number of international initiatives to speed up the development and dissemination of CCS technologies, notably the Carbon Sequestration Leadership Forum (CSLF), which provided a mandate for the involvement of the Department of Science and Technology (DST), and effectively engaged with industry experts. Popularizing the CCS technology is the only option to reduce the emissions and save the planet.
