+
+Creative Commons public licenses provide a standard set of terms and

+original works of authorship and other material subject to copyright
+and certain other rights specified in the public license below. The
+following considerations are for informational purposes only, are not

+
+     Considerations for licensors: Our public licenses are
+     intended for use by those authorized to give the public
+     permission to use material in ways otherwise restricted by
+     copyright and certain other rights. Our licenses are
+     irrevocable. Licensors should read and understand the terms
+     and conditions of the license they choose before applying it.
+     Licensors should also secure all rights necessary before
+     applying our licenses so that the public can reuse the
+     material as expected. Licensors should clearly mark any
+     material not subject to the license. This includes other CC-
+     licensed material, or material used under an exception or

+     licenses, a licensor grants the public permission to use the
+     licensed material under specified terms and conditions. If
+     the licensor's permission is not necessary for any reason--for

+     such as asking that all changes be marked or described.
+     Although not required by our licenses, you are encouraged to
+     respect those requests where reasonable. More considerations

+
+  h. Licensor means the individual(s) or entity(ies) granting rights
+     under this Public License.
+
+  i. Share means to provide material to the public by any means or

+     resulting from Directive 96/9/EC of the European Parliament and of
+     the Council of 11 March 1996 on the legal protection of databases,
+     as amended and/or succeeded, as well as other essentially
+     equivalent rights anywhere in the world.
+
+  k. You means the individual or entity exercising the Licensed Rights
+     under this Public License. Your has a corresponding meaning.
+
+
+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part; and
+
+            b. produce, reproduce, and Share Adapted Material.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material (including in modified
+          form), You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+
+                ii. a copyright notice;
+
+               iii. a notice that refers to this Public License;
+
+                iv. a notice that refers to the disclaimer of
+                    warranties;
+
+                 v. a URI or hyperlink to the Licensed Material to the
+                    extent reasonably practicable;
+
+            b. indicate if You modified the Licensed Material and
+               retain an indication of any previous modifications; and
+
+            c. indicate the Licensed Material is licensed under this
+               Public License, and include the text of, or the URI or
+               hyperlink to, this Public License.
+
+       2. You may satisfy the conditions in Section 3(a)(1) in any
+          reasonable manner based on the medium, means, and context in
+          which You Share the Licensed Material. For example, it may be
+          reasonable to satisfy the conditions by providing a URI or
+          hyperlink to a resource that includes the required
+          information.
+
+       3. If requested by the Licensor, You must remove any of the
+          information required by Section 3(a)(1)(A) to the extent
+          reasonably practicable.
+
+       4. If You Share Adapted Material You produce, the Adapter's
+          License You apply must not prevent recipients of the Adapted
+          Material from complying with this Public License.
+
+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
+
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database;
+
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material; and
+
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
+     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
+     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with
+     this Public License, then Your rights under this Public License
+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:
+
+       1. automatically as of the date the violation is cured, provided
+          it is cured within 30 days of Your discovery of the
+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop
+     distributing the Licensed Material at any time; however, doing so
+     will not terminate this Public License.
+
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.
+
+
+Section 7 -- Other Terms and Conditions.
+
+  a. The Licensor shall not be bound by any additional or different
+     terms or conditions communicated by You unless expressly agreed.
+
+  b. Any arrangements, understandings, or agreements regarding the
+     Licensed Material not stated herein are separate from and
+     independent of the terms and conditions of this Public License.
+
+
+Section 8 -- Interpretation.
+
+  a. For the avoidance of doubt, this Public License does not, and
+     shall not be interpreted to, reduce, limit, restrict, or impose
+     conditions on any use of the Licensed Material that could lawfully
+     be made without permission under this Public License.
+
+  b. To the extent possible, if any provision of this Public License is
+     deemed unenforceable, it shall be automatically reformed to the
+     minimum extent necessary to make it enforceable. If the provision
+     cannot be reformed, it shall be severed from this Public License
+     without affecting the enforceability of the remaining terms and
+     conditions.
+
+  c. No term or condition of this Public License will be waived and no
+     failure to comply consented to unless expressly agreed to by the
+     Licensor.
+
+  d. Nothing in this Public License constitutes or may be interpreted
+     as a limitation upon, or waiver of, any privileges and immunities
+     that apply to the Licensor or You, including from the legal
+     processes of any jurisdiction or authority.

+
+How we got here, what each state publishes, and what we checked ourselves vs. took from agency pages or
+secondary reporting.
+
+## 1. Can NEI give a data-center emissions trend? No.
+
+Test state: Virginia. Reference list: 183 unique DEQ registration numbers from the Public Evidence Project's
+index of DEQ data-center air permits (194 rows). In NEI, Virginia's agency facility ID is the 5-digit DEQ
+registration number, so the join is exact.
+
+| NEI year | permitted data centers present | NOx t |
+|---|---|---|
+| 2012-2014 | 1 | 2-17 |
+| 2015-2021 | 3 | 41-85 |
+| 2022 | 28 | 362 |
+| 2023 | 28 | 394 |
+
+- 155 of 183 permitted registrations never appear in any NEI year 2012-2023.
+- The 2022 jump is 25 sites appearing at once, including one permitted since 2003: a reporting change.
+- For comparison, DEQ's own 2024 data has 148 data-center sites reporting 796 t NOx.
+
+NAICS 518210 facilities in NEI, 12 large markets, 2017 -> 2023: VA 2 -> 23, TX 1 -> 4, GA 0 -> 1, OH 0 -> 4,
+AZ 0 (all years), OR 0 -> 19, WA 0 (all years), NV 2 -> 4, CA 91 -> 118, IL 12 -> 11, IA 2 -> 4, PA 1 -> 6.
+NAICS alone undercounts: Virginia data centers also use 541513.
+
+## 2. What states publish
+
+"Verified" = we downloaded the data and found data centers in it. Other entries come from agency pages and
+rules as read on 2026-11-04 and were not re-verified row by row.
+
+| State | Public facility-level actuals? | Notes |
+|---|---|---|
+| VA | yes, 2024 only (verified) | DEQ ArcGIS: Air Sites layer has a data-center flag (199 sites, covering all 183 permit-index registrations); emissions layer is current year only. VCU's 2015-2024 series came from DEQ directly. Emissions statements required at 25 tpy VOC/NOx in emissions control areas (9VAC5-20-160); permits also require annual emissions data. Generator run logs: on site, records request only. |
+| CA | yes (CARB verified) | CARB facility tool by SIC, 2000-2024 in our pull, criteria tons, no PM2.5. Bay Area AQMD toxic air contaminant inventory 2012-2024 covers all permitted facilities since reporting year 2020 (diesel PM only for engines). Per-engine hours reported at permit renewal; the spreadsheet has been released by records request, not posted. Other districts not checked. |
+| PA | yes (export verified) | DEP 25-year site-level inventory (Power BI) 1999-2025; synthetic minors report since 2020. 23 NAICS-518210 facilities in DEP's facility list, 8 with emission rows. DEP Data Center Permit Tracker lists permits, not emissions. Allegheny County separate. |
+| AZ | yes, Maricopa (scraped) | Annual inventories from non-Title V permittees on request (Rule 100 §505), criteria + HAPs per engine, 2001-2025. No bulk export. Other counties/ADEQ not checked. |
+| OR | partly (2020 toxics file verified) | Statewide air toxics inventories 2016/2020. Standard ACDP annual reports 2013-2023 (scanned PDFs) include monthly hours per generator split into maintenance, emergency and demand response. Post-2024 reports in DEQ's online records portal (not checked). DEQ counts 39 campuses and 2,482 large generators (2026). |
+| TX | partial (verified) | TCEQ STARS site summaries 2010-2024; only sites over 30 TAC 101.10 thresholds; emergency generators under PBR 106.511 need no registration. Abilene/Stargate absent from 2024. |
+| OH | partial | EIS archive 2000-2023 covers Title V and synthetic minors; 4 data centers in 2023 (not yet in this dataset beyond NEI). |
+| IA | partial | Title V actuals published (Microsoft West Des Moines campuses); minor sources report every 3 years, not published. |
+| GA | majors only | Public point-source files cover majors; one data center (QTS Metro). No state list of data-center permits. |
+| WA | no (records request) | Ecology approval orders require annual reports with monthly emissions, hours per engine and every engine start with its purpose; not posted. Public point-source file has no data centers. |
+| IL | no (records request) | 35 IAC 254 requires annual emission reports from all permitted sources; database not published. |
+| NV | no (records request) | Clark County and NDEP collect annual inventories; only a 2017 NDEP summary is public. Washoe County dropped annual reporting in 2025. |
+
+## 3. Known limits of v1
+
+- Reported values are emission-factor estimates. Pollutants and reporting-year definitions differ by state.
+- Hyperscaler sites often sit under shell LLCs. We added the ones with documented evidence (`aliases.csv`);
+  the rest are missing or unattributed. Google, Apple and Meta are not found by name in Maricopa County.
+- Oregon criteria pollutants come from NEI; the state annual reports are not parsed yet.
+- Pennsylvania's export was done by hand and isn't scripted.
+- Values flagged by `qa_flag` are kept as reported.
