Running Tide, a climate-conscious start-up based in the US, has embarked on an unprecedented journey to cleanse the planet of excess carbon dioxide (CO2). This endeavor has now led to the production of the ‘first ever’ carbon removal credits from an open ocean project, an effort that was pre-sold to the prominent e-commerce giant, Shopify.

This groundbreaking initiative aligns with the universal fight against climate change, aiding in the ambitious goals set by the Paris climate agreement. By extracting carbon dioxide from the atmosphere, Running Tide takes a significant step towards controlling the adverse effects of Global warming.
So, what exactly is Running Tide’s method of removing carbon? The process is both unique and inspiring. Waste wood, including wood chips, which would usually be burnt, is coated with limestone and then dispatched to the ocean. This occurred 190 miles south of Iceland, where the limestone-enriched wood was spread across the water’s surface. The limestone serves a dual purpose, not only helping to sequester carbon but also fighting against ocean acidification.
As the wood sinks into the depths, nearly a mile under the ocean, it effectively traps the carbon, preventing it from re-entering the atmosphere. Throughout May, June, and July, Running Tide managed to sink a total of 1,000 metric tons of waste wood, thereby removing an impressive 275 net metric tons of CO2.
This project was no random experiment but rather a meticulously planned venture. Adhering to strict standards from the Scientific Advisory Board and undergoing rigorous review by an independent science board, Running Tide ensured the process’s safety and effectiveness.
Shopify, recognizing the potential of this project, made an advanced purchase of Running Tide’s removal credits in 2020, thus supporting the development phase. Shopify’s head of sustainability, Stacy Kauk, emphasized the importance of “funding innovation” and taking risks to spur the carbon removal industry.
With a current charge of $250-$350 per tonne, Running Tide’s initiative not only marks a significant achievement in carbon removal technology but also exemplifies the potential of human innovation to harness nature for a sustainable future.
It’s an exciting era for environmental enthusiasts as companies like Running Tide redefine the boundaries of ecological preservation. Their efforts are a beacon of hope, signaling that our oceans might just hold the key to a cleaner, greener tomorrow.
