What to do with this
Using Alcoa's emissions profile
- Alcoa runs high-intensity per facility (1.4M MT CO₂e/site); see how it stacks up against the rest of the Metals sector on the Metals industry page.
- It ranks #100 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.
