In 2025, Indian Oil completed a corporate carbon footprint assessment and publicly disclosed its greenhouse gas (GHG) emissions according to the GHG Protocol, covering Scope 1 (direct emissions from owned or controlled sources), Scope 2 (indirect emissions from purchased energy) and Scope 3 (indirect emissions across the value chain).
However, Indian Oil has not published a category-level breakdown of its Scope 3 emissions, limiting visibility into specific value chain sources.

In 2025, the total operational greenhouse gas (GHG) emissions of Indian Oil amounted to 22,530,000 metric tons of CO2 equivalent. This figure includes both direct emissions from owned or controlled sources (Scope 1) and indirect emissions from purchased energy (Scope 2).a
Compared to 2024, the total operational greenhouse gas (GHG) emissions of Indian Oil decreased by 1.01%, showing that the company has made progress in taking action to reduce the climate impact of its operations.a
In 2025, the total Scope 1 emissions of Indian Oil were 21,240,000 metric tons of CO₂ equivalent (tCO₂e).a
Since 2021, Indian Oil's Scope 1 emissions have increased by 5.1%, reflecting a rising long-term trend in Scope 1 emissions over time.ac
Compared to the previous year (2024), Indian Oil's Scope 1 emissions decreased by 3.45%, highlighting the company's efforts to lower direct emissions from assets it owns or controls.a
In 2025, Indian Oil reported Scope 2 greenhouse gas (GHG) emissions of 1,290,000 tCO₂e without specifying the calculation method.a
Since 2021, Indian Oil's Scope 2 greenhouse gas (GHG) emissions (Unspecified Calculation Method) have increased by 84.29%, reflecting a rising long-term trend in Scope 2 emissions over time.ac
In 2025, Indian Oil reported its Scope 2 emissions using an unspecified methodology.a
In 2025, Indian Oil reported 353,880,000 metric tons of CO₂ equivalent (tCO₂e) of Scope 3 greenhouse gas (GHG) emissions, representing indirect emissions across its upstream and downstream value chain.a
The 2025 disclosure of Indian Oil includes a breakdown across 0 of the 15 Scope 3 categories defined by the GHG Protocol, down from 6 in 2024, indicating a decline in reporting granularity and reduced insight into the company's full value chain emissions.a
In 2025, Indian Oil reported total Scope 3 emissions of 353,880,000 metric tons of CO₂ equivalent (tCO₂e).a
Since 2021, Indian Oil's Scope 3 emissions have increased by 46.3%, reflecting a rising long-term trend in Scope 3 emissions over time.ac
Compared to the previous year (2024), Indian Oil's Scope 3 emissions remained relatively stable, indicating that Indian Oil's emissions have plateaued with no significant change in its value chain footprint.ab
In 2025, Indian Oil reported Scope 1 greenhouse gas (GHG) emissions of 21,240,000 tCO₂e and total revenues of USD 88,729 millions. This translates into an emissions intensity of 239.38 tCO₂e per millions USD.a
In 2025, Indian Oil reported a Scope 1 emissions intensity of 239.38 tCO₂e per millions USD. Compared to the peer group median of 216.15, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, Indian Oil ranked 15 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Indian Oil is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Indian Oil reported a total carbon footprint of 376,410,000 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 0.68% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.ab
The largest contributor to Indian Oil's total carbon footprint was Scope 3 emissions, accounting for 94.01% of the company's total carbon footprint, followed by Scope 1 emissions at 5.64%.a
