FAQ
What is a carbon credit platform?
A carbon credit platform helps individuals or organizations discover, evaluate, purchase, manage, or retire carbon credits. Some platforms operate marketplaces, while others specialize in procurement, ratings, portfolio management, carbon removal, or market infrastructure.
What are the best carbon credit platforms?
The right platform depends on the buyer's needs. Options include Carbon Compared for project comparison, Pachama for nature-based projects, Sylvera for carbon credit ratings, Ceezer and Senken for enterprise procurement, Carbonfuture for carbon removal, and Cloverly for API-based climate integrations.
How do companies buy carbon credits?
Companies can purchase carbon credits through marketplaces, project developers, brokers, or procurement platforms. Many platforms allow buyers to compare projects by methodology, location, price, certification, permanence, and expected delivery before purchasing or retiring credits.
What should buyers look for when comparing carbon credits?
Important factors include additionality, permanence, verification methodology, project transparency, delivery risk, vintage, location, third-party ratings, price, and how credits are tracked and retired.
What is the difference between carbon avoidance and carbon removal credits?
Avoidance credits represent activities intended to prevent or reduce emissions that might otherwise occur. Carbon removal credits represent projects that remove carbon dioxide from the atmosphere and store it through biological, geological, or technological processes.
Can individuals buy carbon credits?
Yes. Some carbon credit platforms support individual and small-business purchases, while others are designed primarily for enterprise buyers purchasing larger volumes or building long-term carbon portfolios.
