Carbon Markets as key policy instrument to combat Global emissions

Abstract

Carbon markets have emerged as a key policy instrument to combat global emissions by treating greenhouse gases (GHGs) as tradable commodities, encouraging activities that reduce, avoid, or capture emissions. Rooted in the Kyoto Protocol and reinforced by the Paris Agreement, carbon markets operate through compliance (cap-and-trade) and voluntary mechanisms, engaging diverse stakeholders — project developers, verifiers, standard bodies, and credit buyers. These markets foster climate action by enabling companies and individuals to offset their emissions while promoting renewable energy, afforestation, and energy efficiency projects. Technological advancements like blockchain-based carbon credits and tokenization have enhanced market transparency and liquidity. However, challenges persist, including conflicts of interest in project validation, limited participation of small-scale players, and regulatory ambiguities. Strengthening governance, ensuring inclusivity for marginalized groups, and promoting micro-carbon projects are essential for their success. With India’s commitment to achieving net-zero emissions by 2070, carbon markets hold immense potential to accelerate climate goals, driving both environmental sustainability and economic growth. The present article provides a broad understanding of carbon markets, covering their origin and evolution, current status, processes, stakeholders, as well as the lacunae and challenges they face, along with future prospects.
