To develop a credible and science-based Net Zero Emissions roadmap, GAIL undertook a comprehensive
assessment of its
historical and projected GHG emissions. The Company has been reporting its greenhouse gas emissions since
2011, and
time series data were analysed to understand trends and peak emission years. GAIL has adopted FY 2021-22
as the base
year for its GHG emissions assessment and target-setting. For the purpose of projection, the highest
emissions
observed over the past three financial years have been considered as the baseline reference, ensuring
consistency
and comparability.
GAIL has adopted a science-based approach to formulate a comprehensive roadmap for achieving Net Zero
emissions.
GAIL’s Net Zero ambition is underpinned by a robust assessment of its GHG emissions footprint across the
three
scopes. Scope-1 emissions represent direct emissions from owned or controlled operations, while Scope-2
covers
indirect emissions from the consumption of purchased electricity or steam. Scope-3 emissions, which often
constitute
the largest share in the Oil & Gas value chain, include indirect emissions from activities such as
employee commute
and the use of sold products like Natural Gas and Liquid Hydrocarbons.
Net Zero Action Plan
In FY 2025-26, GAIL continued to pursue its Net Zero target through Electrification of Natural Gas-based
equipment, generation of equivalent Renewable Energy, Compressed Biogas (CBG), Green Hydrogen, CO₂
Valorisation, Energy Efficiency Improvement Projects, and Nature-based Offsetting.
GAIL continues to base its decarbonisation strategy on three elements: Avoidance, Mitigation, and
Offsetting with new expansion projects preferably designed as "Net Zero by Design" to avoid increasing
baseline emissions. GAIL has also planned capital investment of approximately INR 6,400 Crore in Renewable
Energy and green fuel projects during this phase.
GAIL has developed its Net Zero Plan based on the following abatement levers:
- Electrification
Electrification of the compressor at Vijaipur (3.6 MW electric motor drive, commissioned January 2025) continues in successful operation. Electrification of three additional compressors of similar capacity is planned/underway.
- Renewable Energy (RE)
RE capacity grew from 146 MW during FY 2024-25 to 154 MW (118 MW wind + 36 MW solar) during FY 2025-26. The target remains 3,600 MW by 2035.
Commissioned this year: 7.75 MW Floating Solar and 1.8 MW ground-mounted solar, both at Vijaipur.
Under execution: 17.5 MW Floating Solar at Pata; 12.5 MW Rooftop Solar across various installations; 178.2 MW Wind Power Project in Maharashtra.
Approved, work commencing shortly: 600 MW Solar + 550 MWh BESS in Uttar Pradesh (Jhansi); 100 MW Solar + 22 MWh BESS in Maharashtra.
- Compressed Biogas (CBG)
GAIL still plans 26 CBG plants overall. The Ranchi plant (5 TPD, based on 150 TPD MSW) has been running since January 2025. Six additional projects (~94.6 TPD combined capacity) are under implementation across Bengaluru, Sultanpur, SBS Nagar, Moga, Ambikapur, and Korba.
through surveys, workshops, and consultations to evaluate the importance and severity of impacts.
- Green Hydrogen
The 10 MW PEM Electrolyser-based Green Hydrogen plant at Vijaipur continues to operate, with hydrogen blended with natural gas for captive fuel use. GAIL is making provision for cascade filling of Green Hydrogen at Vijaipur, expected to be operationalised in FY 2026-27, enabling commercial sale of the product.
- Carbon Valorization
The 1 TPD pilot-scale biological CO₂ capture project using microalgae continues at Pata. The 15 TPD CO₂-to-Ethylene pilot with the partner is now in the trials stage (progressed from "startup and commissioning" last year). GAIL continues to explore CO₂-to-SAF and other value-added pathways.
- Energy Efficiency Improvement Projects
Energy Efficiency is often called the “first fuel” in clean energy transitions, as it provides some of the quickest and most cost-effective CO2 mitigation options while lowering energy bills. Energy Management System is implemented at major O&M locations and various energy efficiency improvement initiatives are being undertaken on a regular basis. The Company’s major installations are already ISO-50001 Energy Management System certified.
- Nature based Offsetting
Afforestation forms an integral part of GAIL's carbon offsetting strategy, contributing to enhanced carbon sequestration, biodiversity conservation, ecosystem restoration, and climate resilience. Through sustained tree plantation programmes, GAIL continues to strengthen green cover across its operational locations and surrounding communities, complementing its broader decarbonisation initiatives.
More than 4 Lakh trees have been planted in the last 03 years, including plantation of ~75,000 trees near Vijaipur (Guna), ~42,000 trees under ‘Ek Ped Maa Ke Naam 1.0’ and
~48,000 trees under ‘Ek Ped Maa Ke Naam 2.0’ across various GAIL locations.
