What it does
This bill creates two main mechanisms: (1) it exempts AI data centers from federal bonus depreciation tax benefits UNLESS they achieve LEED Platinum or Gold green building certification, and (2) it requires large data centers (25+ megawatts) to disclose detailed information about water usage, electricity consumption, backup power, and emissions to federal agencies and state governments, with civil penalties up to $100,000/day for knowing violations. The bill aims to increase transparency about data center environmental impact while incentivizing green building standards.
Why we flagged it
The bill combines a mandatory environmental disclosure regime (Section 3) with a tax-code amendment (Section 2) that conditions bonus depreciation eligibility on green building certification. It is neither purely a tax bill nor purely a disclosure bill—it uses tax policy as a lever to drive environmental compliance.
What the text implies
- LEED certification requirement may create a de facto barrier for smaller or less-capitalized data center operators, concentrating market share among larger firms that can absorb certification costs.
- Disclosure of water rights, permits, and long-term supply agreements may expose competitive or proprietary business arrangements to public scrutiny and local political pressure.
