India is strengthening its national greenhouse gas inventory systems and improving emissions accounting as part of its contribution to global climate action. The country has recently submitted its first Biennial Transparency Report (BTR-1) to the United Nations Framework Convention on Climate Change (UNFCCC). Following that submission, a three-day knowledge sharing workshop on the national greenhouse gas inventory was jointly organised by the CSIR-Indian Institute of Petroleum (CSIR-IIP) and the Ministry of Environment, Forest and Climate Change (MoEFCC) at CSIR-IIP in Dehradun from 20th to 22nd May 2026. The event assembled technical experts and policymakers to review methodologies and reporting requirements. Participants included specialists from the CSIR-Central Institute of Mining and Fuel Research (CSIR-CIMFR), Central Mine Planning and Design Institute Limited, the Confederation of Indian Industry, IIT-Indian School of Mines Dhanbad, the National Institute of Advanced Studies, the Alliance for an Energy Efficient Economy and Jadavpur University. Sessions were chaired by senior officials and academics including advisers and additional directors from the MoEFCC, a professor from IIM Ahmedabad and senior scientists from CSIR-IIP. The agenda prioritised sectoral approaches and harmonised methods for inventory compilation. The programme featured technical and brainstorming sessions on preparation of the Second Biennial Transparency Report (BTR-2) and on development of country specific emission factors for India. Discussions addressed emissions accounting for the Energy and Industrial Processes and Product Use (IPPU) sectors, with attention to iron and steel, road transport, pipeline transportation, fugitive emissions and industrial process emissions. Delegates also examined reporting of key categories and the role of ethanol blending in transportation fuels and its projected contribution to reducing fuel imports under the Government of India vision of Viksit Bharat by 2047. The workshop concluded with deliberations on the planned submission of BTR-2 by the end of 2026 and BTR-3 by 2028. A newly constructed selfie point at CSIR-IIP was inaugurated after the event. Organisers indicated that continued collaboration between research institutes and industry will support enhanced transparency and methodological rigour in national inventory preparation ahead of forthcoming reporting milestones.
