Biogas has emerged as a promising renewable energy option for addressing energy poverty, environmental degradation, and rural development challenges. In alignment with Sustainable Development Goal 7 (SDG 7), which calls for universal access to affordable, reliable, sustainable, and modern energy, biogas holds significant potential in India due to the country’s agrarian economy, large livestock base, and abundant organic waste. Despite its technical viability and socio-economic benefits, adoption levels remain below expectations, largely due to limited awareness, inadequate financing mechanisms, and weak marketing approaches. This paper explores the marketing of biogas in India, with particular attention to strategies that emphasize economic, health, environmental, and social benefits. By drawing upon national initiatives such as the National Biogas and Manure Management Programme (NBMMP) and community-based dissemination models, the study identifies critical gaps in outreach and consumer engagement. A SWOT analysis is presented to examine the strengths, weaknesses, opportunities, and threats of biogas marketing in India. The findings underscore the need for integrated marketing approaches that combine policy support, financial innovation, and grassroots-level awareness campaigns. The study concludes with policy and business recommendations to scale biogas adoption, positioning it as a sustainable and market-driven solution to achieve SDG 7 in India.
