Compressed Biogas (CBG): A National Blueprint for Upscaling Policy and Practice

April 24, 2026

Centre for Science and Environment (CSE) report on Compressed Biogas attempts to highlight the complete CBG ecosystem in India—its current status, challenges and opportunities - with the aim of presenting a set of recommendations (a ‘national blueprint’) for upscaling the sector keeping its potential in mind. The selection of the three states - Punjab, Haryana and Gujarat - for a deep-dive was based on ground truths. Punjab and Haryana, where agriculture is dominant, face the issue of biomass or stubble burning every year: CBG plants can ensure biomass utilisation in these states, thus helping reduce open stubble burning. Gujarat was shortlisted because it is one of India’s leading states in terms of functional CBG plants and offers models and success stories that the rest of the country can replicate.

CSE researchers have studied the CBG ecosystem in these states, including the state policies (if available), status of operational plants, issues and challenges related to feedstock, CBG off-take, and bio-digestate management. They also examined the cost economics and feasibility of the operational plants, and documented the good practices.
