Pemex said its direct greenhouse gas (GHG) emissions from its activities, known as Scope 1, fell by 11pc in 2023 to 64.1mn t CO2 equivalent (CO2e).
Scope 1 emissions from operations at its Deer Park refinery in Texas totaled 3.1mn t CO2e, 3.1pc less than in 2022.
The state-run company also reduced its methane (CH4) emissions by 14.6pc. Methane emissions from gas processing complexes fell from 140mn t in 2022 to 26mn t in 2023. Reductions were supported by a sharp decline in its petrochemical production last year, which fell by 18.4pc.
Methane emissions in its upstream activities remain almost flat, but the company increased the amount of methane vented directly to the atmosphere. Pemex only sent 56.1pc of its methane emissions to flares while it vented 43.8pc. In 2022, it had sent 67.6pc of its methane emissions to flares and 32.2pc vented to the atmosphere.
The state-owned company averaged 4,700 b/d of fuel stolen in 2023, equivalent to Ps 20.2bn ($1.07bn) in losses, according to the report. The amount of stolen product was lower than the 6,100 b/d in 2022, but the losses increased as a year before it only reported Ps 18.7bn ($983mn).
The firm's Scope 2 emissions — emissions caused indirectly from energy it purchases and uses — fell by 7.9pc on the year to 1.98mn t CO2e.
