Overview

GreenWave's Kelp Climate Fund is a subsidy program for ocean farmers to support a bundle of climate impacts, including carbon sequestration, nitrogen removal, and reef restoration.

GreenWave intends to grow the fund to $1 million in annual seed subsidies supporting 250 farmers planting 1 million feet of kelp seed.

Geographic Scope: North America (United States and Canada)

Focus Areas:

  • Blue carbon capture and sequestration

Eligibility:

  • Ocean farmers growing more than 1,000 feet of kelp seed
  • All seaweed farmers in North America meeting minimum acreage requirements
  • Accepted on first-come, first-serve basis until fund is spent down

What the Program Provides:

  • Access to GreenWave's My Kelp app for data collection and tracking

Program Evolution (2025-26 Season):

  2. Spring Sales & Stabilization Bonus: $1 per pound match of kelp sold or stabilized (up to $15,000), paid in spring with proof of delivery or processing

Farmers can earn up to $25,000 per year combined.
