In 2025, Moderna 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) and Scope 2 (indirect emissions from purchased energy).
However, Moderna 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 Moderna amounted to 31,746 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 Moderna increased by 2.79%, suggesting that the company faced challenges in reducing its emissions from its core operations.a
In 2025, the total Scope 1 emissions of Moderna were 10,463 metric tons of CO₂ equivalent (tCO₂e).a
Since 2021, Moderna's Scope 1 emissions have increased by 14.46%, reflecting a rising long-term trend in Scope 1 emissions over time.a
Compared to the previous year (2024), Moderna's Scope 1 emissions decreased by 20.61%, highlighting the company's efforts to lower direct emissions from assets it owns or controls.a
In 2025, Moderna reported Scope 2 greenhouse gas (GHG) emissions of 284 tCO₂e using the market-based method and 21,283 tCO₂e using the location-based method.a
Since 2021, Moderna's Scope 2 greenhouse gas (GHG) emissions (Location-Based) have increased by 162.14%, reflecting a rising long-term trend in Scope 2 emissions over time.a
Compared to the previous year (2024), Moderna's Scope 2 emissions (Location-Based) rose by 20.21% in 2025, suggesting that the company faced challenges in reducing emissions from purchased electricity and energya
In 2025, Moderna reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Moderna reported Scope 1 greenhouse gas (GHG) emissions of 10,463 tCO₂e and total revenues of USD 1,922 millions. This translates into an emissions intensity of 5.44 tCO₂e per millions USD.a
In 2025, Moderna reported a Scope 1 emissions intensity of 5.44 tCO₂e per millions USD. Compared to the peer group median of 2.77, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, Moderna ranked 15 out of 21 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Moderna is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
