Across the 40 most recent environmental services rounds shown, the largest disclosed amount is $17M for Aquafortus (2023-02-23). That level stands out against a next tier of $8M–$10M rounds (e.g., Ucaneo $8M on 2024-09-10; Rebalance Earth $7M on 2024-09-09; HeatTransformers $16M on 2023-04-04; ClearBlue Markets $8M on 2023-03-20), while many other disclosed rounds cluster closer to the $100K–$2M band (e.g., Agricarbon $50K on 2025-03-04; PuriFire Labs $120K on 2023-02-15).
The stage and disclosure mix is also skewed: 11 of 40 entries are “undisclosed” and 19 of 40 are “Series Unknown,” with only a handful explicitly labeled Seed/Pre-Seed/Angel/Series A (e.g., Ucaneo Seed $8M on 2024-09-10; HeatTransformers Series A $16M on 2023-04-04). Geographically, the list shows a UK concentration (multiple entries in London, plus Seafields Solutions in Stockport and Bluemethane in the UK) and several date-adjacent launches in late Q1–Q2 windows (e.g., 2023-03-20 to 2023-04-04 includes ClearBlue Markets $8M, Aquafortus $17M, HeatTransformers $16M, and Bygen $2M on 2024-04-15 is a separate later spike). The rounds span 2022-11-14 (Reefy) through 2026-05-12 (BurnBot), with the newest row undisclosed.

Frequently asked
What are the largest and smallest disclosed rounds in this environmental services set, and how uneven is the spread?
The largest disclosed amount is Aquafortus at $17M (2023-02-23). The smallest disclosed amount is Agricarbon at $50K (2025-03-04); between them, many disclosed deals sit in a lower $100K–$2M band (e.g., PuriFire Labs $120K on 2023-02-15; Tree Trust $2M on 2023-05-08).
Do any disclosures or labeled stages dominate the list compared with explicitly named rounds?
“Series Unknown” appears in 19 of 40 rows, and “undisclosed” appears in 11 of 40 rows, so 30 of 40 entries provide no comparable disclosed stage+amount pairing (e.g., BurnBot 2026-05-12 undisclosed; Plant-for-the-Planet 2024-12-03 undisclosed). Where stages are specified, Seed/Pre-Seed/Angel/Series A are represented but less frequent (e.g., HeatTransformers Series A $16M on 2023-04-04; Blume Pre-Seed $100K on 2024-05-14; Waro Angel $1M on 2023-10-16).
Which city or geography shows clustering rather than one-off coverage?
London shows repeated activity: Zulu Ecosystems is listed in London (2024-09-18, $760K) and Rebalance Earth is also London (2024-09-09, $7M), while Greenspark (2023-02-01) is also London (undisclosed). The UK appears again via other locations (e.g., Seafields Solutions in Stockport 2023-04-25 at $370K, and Bluemethane in the UK listed for 2024-05-14 at $100K).
Are there notable bursts in the most recent time window (e.g., last ~12 months of the rows shown)?
From 2025-06-12 (Open Space Institute $1M) through the newest 2026-05-12 (BurnBot undisclosed), the disclosed entries vary widely but still include several mid-sized rounds: Ucaneo’s Seed $8M (2024-09-10) is just outside that window, while within 2025–2026 disclosed amounts include Open Space Institute $1M (2025-06-12) and Agricarbon $50K (2025-03-04). Several 2025/2026 rows also remain undisclosed (e.g., BurnBot 2026-05-12; 3R-BioPhosphate 2026-04-23; C-LEANSHIP 2026-04-22).
Which outliers are worth closer attention because they sit far from the rest of the disclosed amounts?
Aquafortus’ $17M (2023-02-23) and HeatTransformers’ $16M (2023-04-04) are the clearest high outliers relative to most other disclosed amounts like $1M (Open Space Institute 2025-06-12), $760K (Zulu Ecosystems 2024-09-18), and $90K (Ecobean 2022-12-01). On the low end, the $50K Agricarbon round (2025-03-04) undercuts the rest of the disclosed range, including $60K Washington Water Trust (2023-12-06) and $90K Ecobean (2022-12-01).
