What to do with this
Using Occidental Petroleum's emissions profile
- Occidental Petroleum runs high-intensity per facility (247K MT CO₂e/site); see how it stacks up against the rest of the Petroleum and Natural Gas Systems sector on the Petroleum and Natural Gas Systems industry page.
- It ranks #66 of 2,289 reporting parents nationwide, compare it directly against specific peers on the compare tool.
- Not sure how to read a total-CO₂e figure or a per-facility intensity number, the how-to-read guide walks through what each field means and what it doesn't.
