Through the deal with carbon-removal startup Planetary, Frontier Climate aims to reduce ocean acidity and ultimately remove 115,211 tonnes of carbon from seawater between 2026 and 2030. (The Logic)

Talking point: Frontier launched in 2022 as a joint initiative between Shopify, Google, Stripe, Meta, and McKinsey Sustainability. The company is trying to make it more financially feasible for startups to remove emissions by providing revenue for the carbon dioxide they capture and store. Last year, the firm bought more than 667,000 tonnes of CO2 across 16 deals, an analysis by The Logic found. Most of its deals so far have focused on removing carbon from the atmosphere. While the ocean serves as a natural carbon sink, levels of CO2 in the waters have increased dramatically in recent decades. Planetary adds antacids to the seawater to help restore the chemical balance and has project sites in Nova Scotia and Virginia.
