SHUT DOWN June 2024. Portland, Maine company that raised $54M+ (led by Sacca's Lowercarbon Capital) to dump thousands of tons of Canadian wood chips coated in limestone into the North Atlantic off Iceland. Microsoft removed their credits for failing verification. Scientists departed over ecological concerns.

Key Facts

  • SHUT DOWN June 14, 2024 — all operations ceased, 32 remaining staff laid off (down from 120 at peak)
  • Raised $54M+ led by Chris Sacca's Lowercarbon Capital (Series B, 2022)
  • Shifted from kelp sinking to dumping thousands of tons of Canadian wood chips coated in limestone into the ocean off Iceland
  • Microsoft removed Running Tide credits from its portfolio because they failed verification standards
  • MIT Technology Review reported scientist departures over concerns about ecological effects and undisclosed ocean fertilization discussions
  • Icelandic newspaper investigation revealed the wood chip dumping — Prof. Jon Olafsson (Univ. of Iceland): 'Throwing wood chips into the ocean does nothing for the atmosphere'
  • Sold carbon credits to Shopify, Microsoft, and Stripe — all based on unverifiable claims of permanent ocean carbon storage

Red Flags

1

Verification failure

Running Tide admitted it was 'impossible to monitor the wood chips for more than three hours after release.' Microsoft removed their credits from its portfolio.
