Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-bb10cb721760ac84 quantitative
committed in 2018 to converting its fleet of almost 6,000 buses
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The MTA case study opens: "In 2018, the MTA announced a commitment to transition the entire bus fleet to zero-emissions by 2040." The fleet size is given in the same document: the MTA "is transitioning its fleet of almost 6,000 buses to zero-emissions buses in four stages, closely aligned with the capital planning process."
Caveat
The manufacturer's own announcement of the 2025 order dates the transition plan to 2023 rather than 2018; the two refer to different events — the 2018 commitment and the later published plan. A separate federal write-up counts the fleet as 5,800 buses.

Claim 2 clm-2187a4804154bd6b quantitative
to zero emissions by 2040
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Both the operator and the manufacturer give 2040. The MTA document: "a commitment to transition the entire bus fleet to zero-emissions by 2040", tied to "the MTA's goal to reduce agency-wide greenhouse gas emissions 85% by 2040". New Flyer's release says the agency "unveiled a plan in 2023 to fully transition its 5,800-bus fleet to zero-emission vehicles by 2040".

Claim 3 clm-4d7e89f5d4601dee quantitative
Stage 1 was meant to put 560 battery-electric buses on the road
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The case study sets out four stages and describes the first: "Stage 1 (2015-2019 & 2020-2024) deploys 560 battery-electric buses to test infrastructure and operational feasibility."
Caveat
The document describes Stage 1 as a deployment to test infrastructure and operational feasibility, and does not itself say how many of the 560 were delivered.

Claim 4 clm-d490d2b5b3b1ce90 quantitative
by mid-2025 only 60 New Flyer buses were actually in service
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Streetsblog, reporting the June 2025 board meeting: "The 60 New Flyer electric buses that the MTA has already put into service are extremely unreliable because batteries overheat or fail to fully charge." The MTA's own press release from January 2025 counts the same 60: the 265-bus purchase "builds on the 60 zero-emission buses that came last year".
Caveat
No claim-specific caveat recorded

  2. Mass Transit (reprint of MTA press release) — MTA invests in 265 new zero-emission buses (Feb 2025)
Claim 5 clm-b5dca0b12048a5a5 quantitative
the MTA's own reporting to its board put them at 2,111 miles between major failures against 13,000 miles for diesel buses, available for a full day of service 60% of the time against 91%
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Streetsblog reports the figures presented to the board: "Only 60 percent of battery-electric buses are typically available for a full day of service, compared to 91 percent for diesel buses. And the number of miles a bus can travel before needing major repairs on average is just 2,111 miles for electric buses — and 13,000 miles for standard diesel buses."
Caveat
The report that carried these figures to the board was written by the independent engineer who oversees the MTA's capital projects, so calling them the authority's own reporting is a simplification. The source describes the mileage figure as distance before major repairs rather than between failures.

Claim 6 clm-6cf1bbb3b5112eec quantitative
Deliveries of the next 205 and 265 buses were paused in 2026
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The June 2026 board briefing is reported as: "Transit officials have paused orders on almost 500 electric buses they expected to receive last year and next amid reliability issues with the MTA's existing e-bus fleet." The same piece names both orders: "The 2025 order remains on hold, as does an order of 265 electric buses that was due to arrive in 2027."
Caveat
The 205-bus delivery was first paused in 2025, not 2026; the June 2026 briefing recorded that it remained on hold alongside the 265-bus order.

Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
"MTA board members on Monday advanced an amendment to the authority's 2024 contract with bus manufacturer New Flyer that lowers the number of 40-foot e-buses in the order from 380 to 295, and swaps in 85 diesel-electric hybrids in their stead." The article is dated 27 July 2026.
Caveat
On the day of the report the committee had advanced the amendment; the source says the final board vote was set for two days later.

Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The operator's own case study states it directly: "This transition will require approximately 262 MW of new power supply across 28 bus depots." The same paragraph says the MTA is "exploring options like on-site battery storage and solar generation to reduce grid power demands".
Caveat

Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The MTA press release states that the MTA and NYPA are "commissioning automated overhead pantographs that are expected to be operational at Jamaica Depot in fall of 2027".
Caveat
This is a forward-looking commissioning date given by the operator in January 2025, not an observed one.

Claim 10 clm-63a10dc59f1d7f30 quantitative
State law sets a 2040 deadline for the whole fleet
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Streetsblog writes: "State law mandates that the entire fleet comprise zero-emissions buses by the end of 2040." Two further reports in the same source list say the same thing in other words — the MTA "has committed to meeting the state's mandate to have a fully electric fleet by 2040" (24 June 2025) and "the MTA's legally required transition to a zero-emissions fleet by 2040" (23 June 2026).
Caveat
The statute itself is not among the entry's sources; three reports by the same publication are. The entry previously said the opposite — that no state law requires the transition — which is the error this passage corrects.

a bill that would have required zero-emission-only bus purchases from 2029 was stricken in the New York Senate in May 2024
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The Senate page for S6089 (2023-2024) carries the title "Relates to the purchase of zero-emission buses", the status "Stricken", and the last Senate action "May 06, 2024 — recommit, enacting clause stricken". The bill text reads: "NO LATER THAN JANUARY FIRST, TWO THOUSAND TWENTY-NINE, EVERY PUBLIC TRANSPORTATION SYSTEM ELIGIBLE TO RECEIVE OPERATING ASSISTANCE ... SHALL BE REQUIRED TO PURCHASE ONLY ZERO-EMISSION BUSES."
Caveat
The bill covered every public transportation system in the state eligible for operating assistance, not the MTA alone.

mapped · no interpretation or interpolation added by this passport
What the mapping says
Streetsblog reported the board presentation of 23 June 2025: "Only 60 percent of battery-electric buses are typically available for a full day of service, compared to 91 percent for diesel buses. And the number of miles a bus can travel before needing major repairs on average is just 2,111 miles for electric buses — and 13,000 miles for standard diesel buses." The same piece notes the comparison is not a manufacturer effect: "the diesel buses are also built by New Flyer."
Caveat
The figures were carried to the board in a report by the independent engineer who oversees the MTA's capital projects, so they are not purely the authority's own presentation. The source describes the mileage as distance before major repairs.

A year later the board was given 2,500 miles against 8,500
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Both June and July 2026 reports carry the second pair. In June 2026: "The agency's existing electric buses only go 2,500 miles on average between major failures that take them off the road, compared to 8,500 miles on average for diesel buses, Jessie Lazarus, the MTA's head of rolling stock procurement, told agency board members." The July piece repeats it: the buses "cover only about 2,500 miles on the road before a mechanical breakdown takes them out of service, compared to 8,500 miles for diesel buses."
Caveat
The two pairs are not a like-for-like series. The diesel baseline itself moves from 13,000 to 8,500 miles between the two briefings, and the sources describe the measure differently in each year — distance before major repairs in 2025, distance before a breakdown that takes the bus out of service in 2026. The electric figure rises while the reported diesel figure falls, so the narrowing gap cannot be read as an improvement on a fixed yardstick.

What the mapping says
The quotation and the title are both in the source: "“They’re also in service about 30 or 40 percent less than our diesel buses,” said Lazarus." She is identified in the same article as "Jessie Lazarus, the MTA’s head of rolling stock procurement", speaking at a June 2026 MTA board meeting; the piece adds that she "presented data that indicates that the MTA’s battery-powered New Flyer buses have been breaking down more than three times as frequently as their diesel-powered counterparts."
Caveat
The quoted sentence begins “They’re also in service…” in the source; the entry quotes it from the second word onwards.

Claim 15 clm-ddf9b84f00a1a762 quantitative
In July 2026 the MTA reduced a 380-bus order to 295 and replaced the 85 cancelled battery-electric buses with diesel-electric hybrids, with the remaining deliveries pushed to April–December 2028.

What the mapping says
"MTA board members on Monday advanced an amendment to the authority’s 2024 contract with bus manufacturer New Flyer that lowers the number of 40-foot e-buses in the order from 380 to 295, and swaps in 85 diesel-electric hybrids in their stead. The buses are expected to arrive between April and December of 2028, officials said — three years after the MTA was supposed to begin accepting orders of the battery-electric buses." The article is dated 27 July 2026.
Caveat
The order cut applies to the 40-foot buses in the 2024 New Flyer contract. On the day of the report the committee had advanced the amendment, with the final board vote set for two days later.

Claim 16 clm-2d2a021f227e2299 descriptive
mean distance between failures and availability are standing MTA performance measures
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Both measures appear as routine MTA reporting categories rather than one-off figures. The June 2026 report reproduces an MTA chart captioned "Buses older than 12 years old clearly lag behind their younger compatriots on mean distance between failure", credited to the MTA, and the same article notes Lazarus using the measure for the electric fleet. Availability for a full day of service is reported the same way in June 2025: "An agency review found that just 60 percent of the battery-electric buses could stay in service for a full day."
Caveat
The sources show both measures used in MTA board material and reproduce an MTA chart built on one of them, but none of them states that either is a formally published standing performance indicator.

The quotation is verbatim: "“Our lesson from this experience is that we must set some framework for evaluating the performance of propulsion before we go all in,” Jessie Lazarus, the MTA’s head of rolling stock procurement, told the committee on Monday. “We had 500 spots for battery-electric buses that didn’t really pan out, and so we have to catch up with our net new bus deliveries.”"

mapped · no interpretation or interpolation added by this passport
What the mapping says
The figure is the operator's own: "This transition will require approximately 262 MW of new power supply across 28 bus depots." The case study frames depot power as the central obstacle, calling the charging equipment the investment that is "most consequentially" needed, alongside vehicles and workforce skills.
Caveat
The 262 MW figure is a planning estimate in the transition plan, not a built or contracted quantity.
