In 2025, Carnival reported 7,882,273 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 Carnival includes a breakdown across 2 of the 15 Scope 3 categories defined by the GHG Protocol, down from 8 in 2024, indicating a decline in reporting granularity and reduced insight into the company's full value chain emissions.a
In 2025, Carnival reported total Scope 3 emissions of 7,882,273 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 0% of these emissions originated from upstream activities such as purchased goods and capital goods, while 100% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2019, Carnival's Scope 3 emissions have decreased by 19.06%, reflecting a declining long-term trend in Scope 3 emissions over time.ab
Compared to the previous year (2024), Carnival's Scope 3 emissions remained relatively stable, indicating that Carnival's emissions have plateaued with no significant change in its value chain footprint.a
In 2025, Carnival reported emissions for 2 out of the 15 Scope 3 categories defined by the GHG Protocol.a
The limited disclosure restricts visibility into specific emission sources across the company's value chain.
In 2025, the largest contributors to Carnival's Scope 3 emissions were:a
In 2025, Carnival reported Scope 1 greenhouse gas (GHG) emissions of 9,263,016 tCO₂e and total revenues of USD 26,621 millions. This translates into an emissions intensity of 347.96 tCO₂e per millions USD.a
In 2025, Carnival reported a Scope 1 emissions intensity of 347.96 tCO₂e per millions USD. Compared to the peer group median of 0.44, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, Carnival ranked 25 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
This places Carnival among the least efficient performers, with one of the highest emissions intensities in its sector.a
In 2025, Carnival reported a total carbon footprint of 17,178,803 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 6.56% decrease compared to 2024, indicating progress in reducing its overall greenhouse gas output.a
The largest contributor to Carnival's total carbon footprint was Scope 1 emissions, accounting for 53.92% of the company's total carbon footprint, followed by Scope 3 emissions at 45.88%.a
