Carbon Intensity Benchmarks
Benchmarks based on IOGP Environmental Performance Indicators and IEA data. Scale: 0-100 kg CO2e/BOE.
How this was calculated
Combustion emissions: Oil = 0.43 tonnes CO2/bbl (EPA AP-42, crude oil combustion). Gas = 0.055 tonnes CO2/Mcf (EPA natural gas combustion factor).
Flaring emissions: Flare rate x 0.055 x (1 - combustion_efficiency). Combustion efficiency assumed at 98%. The 2% uncombusted methane is converted at GWP = 28.
Fugitive methane: Leak rate (%) x production volume (converted to Mcf equivalent) x methane density x GWP of 28 (AR5 100-year).
Pneumatic devices: 5.4 tonnes CO2e per device per year (EPA average for gas-driven pneumatic controllers).
Tank emissions: 0.008 tonnes CO2e per bbl throughput per year (flash gas and working/breathing losses).
EPA Methane Fee: Inflation Reduction Act Sec. 60113. $900/ton (2024), $1,500/ton (2026+). Applies to methane emissions above facility thresholds.
Carbon intensity: Total annual CO2e divided by annual BOE production.

The oil and gas industry accounts for approximately 15% of global energy-related greenhouse gas emissions. As ESG reporting requirements tighten and carbon pricing mechanisms expand, operators need accurate tools to quantify their emissions footprint and identify reduction opportunities.
Combustion emissions from burning hydrocarbons are the largest source of CO2 in most operations. Flaring converts waste gas to CO2 but at less than 100% efficiency, meaning some methane escapes uncombusted. Since methane has a global warming potential (GWP) of 28 times CO2 over 100 years, even small amounts of uncombusted methane are significant.
Fugitive emissions from leaking equipment, valves, and connections are often the most cost-effective category to reduce. LDAR (Leak Detection and Repair) programs using OGI cameras, drones, or continuous monitoring can identify and fix leaks quickly. The EPA estimates that fugitive methane represents 1-3% of total gas production in the US.
The Inflation Reduction Act introduced a Methane Emissions Charge starting at $900/ton in 2024, escalating to $1,500/ton in 2026 and beyond. This applies to facilities reporting over 25,000 tonnes CO2e that exceed methane intensity thresholds. Understanding your exposure is the first step to managing it.
