GreenWave

GreenWave

GreenWave is a regenerative ocean farming organization studying how kelp can be added to soil to increase its carbon storage potential while decreasing harmful nitrous oxide emissions on regenerative land farms. This project is part of The Travel Corporation’s Climate Action Plan to invest in carbon removal solutions.

Objective

While there have been many attempts to increase soil’s natural ability to store carbon (known as soil organic carbon), one unintended effect is the release of nitrous oxide, a greenhouse gas that is 300 times more potent than carbon dioxide. The use of kelp as a soil additive is emerging as a tool to reduce nitrous oxide emissions and create a net climate benefit.

GreenWave believes that kelp has strong potential to reduce both the need for nitrogen additives (fertilizer) on agricultural crops and nitrous oxide emissions in soils, progress that would have significant implications for climate benefit, as it counters the concern that increasing soil organic carbon can result in increased nitrous oxide emissions, negating climate change mitigation that comes with higher soil organic carbon storage. If GreenWave is correct and kelp can both reduce the need for nitrogen additives (fertilizer) and reduce nitrous oxide emissions while increasing soil organic carbon, regenerative ocean and land farms can work together to have a net climate benefit, adding another impactful nature-based solution to the fight against climate change.

Impact

TreadRight’s grant will go towards validating GreenWave’s research on the link between kelp’s effect on greenhouse gas emissions and carbon storage through a one-year field study using kelp grown on the GreenWave farm as a soil additive for regenerative land-based farms in the Northeast, USA. During the first year of the soil project, GreenWave will measure the impact on greenhouse gas emissions and assess potential for carbon soil sequestration. If the results are positive, GreenWave will pursue evaluating how regenerative ocean farmers can sell climate offset credits reflecting the amount of climate benefit created. While this will be a longer-term project, it will provide another source of income for regenerative ocean farmers and create incentives to use crops from regenerative ocean farms as a soil additive to create net climate benefits bridging land and sea.

UN GLOBAL GOALS

This solution is taking urgent climate action to address carbon dioxide emissions in the atmosphere.
