Micron's latest full footprint is 11,196,799 tCO2e for FY24, up from 10,552,824 t in CY23; FY25 Scope 3 is not yet calculated. That size brings the 0.70x size deduction. Scope 1 and market-based Scope 2 fell again in FY25. Renewable electricity was 13% of total energy in FY25; its 100% claims for Malaysia, mainland China and the US rest on PPAs, unbundled certificates and green tariffs, with no split published. It has self-set targets, no SBTi commitment and no Scope 3 target. New York's regulator found its planned Clay fabs inconsistent with state greenhouse gas limits, but justified on national-security grounds.
Micron Technology scores 31/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Scores are free. Companies can never pay for anything about their own score. Last verified November 2026.
That places Micron Technology joint 691st of 994 companies scored, and joint 29th of 41 in Electronics / Hardware.
What is Micron Technology doing well, and where does it fall short?
Strongest on Carbon Footprint: Operations and Transparency & Accountability (8/10, 7/10). Weakest on Emissions Trajectory and Nature & Biodiversity Impact (0/10, 2/10).
Where Micron Technology lost points
For each question that lost points, the evidence our public rubric looks for that we didn't find.
- Emissions from its own operations8/10No verified figures published with their method and a falling trend.
- Emissions from its supply chain5/10Most of its supply-chain (Scope 3) emissions aren't measured.
- Whether its emissions are falling0/10No evidence its emissions are falling, not even from energy bills or mileage.
- How clean its energy is4/10Less than half its energy shown to be renewable, or no transition plan.
- Its effect on nature2/10No assessment of its effect on nature, and no basic environmental policy.
- How it uses materials and handles waste5/10No measurable waste or recycling targets reported publicly.
- Its effect on water5/10No measured water footprint with reduction targets.
- Its climate targets4/10Its targets aren't science-based or committed to the Science Based Targets initiative.
- How openly it reports7/10No annual impact report, or no pay linked to climate targets.
- Its record on controversies6/10Points deducted for controversies or its business model. The finding is under question 10.

How is Micron Technology's SINK score calculated?
Same ten questions for every company. No private weighting.
SINK = (0.3 × Base + 0.7 × Performance) × ScaleWhat evidence is Micron Technology's score based on?
12 sources used in this assessment. All publicly available. Each row shows which of the ten questions it informed.
17% of them were published by Micron Technology itself; the rest come from independent sources.
Scope 2, FY2025: market-based 3,820,977 t, location-based 4,437,982 t. The score uses market-based.

The 3 companies in the sector scoring nearest above Micron Technology.
Broadcom reported 3,089,798 tCO2e for 2025, up from 2,631,281 tCO2e in 2024, covering Scope 1, market-based Scope 2 and 12 Scope 3 categories; use of sold products is not reported.
See the breakdown →AMD reports a 30% cut in market-based Scope 1+2 emissions since 2020, but Scope 1 has roughly doubled and location-based Scope 1+2 rose 61% over the same period, so the reduction rests on renewable-energy instruments; Greenpeace reports that over 70% of its renewable energy came from unbundled RECs in 2023.
See the breakdown →LG has strong absolute emissions reductions in operations and comprehensive waste recycling, but renewable energy penetration remains under 20% despite RE100 membership.
