A practical RFP playbook for blue-carbon credit buyers: what to specify, which questions to ask, how to score bids and what to contract for.

The eight quantification and accounting errors that most often damage kelp-carbon projects — and the specific checks that catch each one early.

Carbon credits come in two fundamentally different kinds — removals and avoidance. Knowing the difference is the single most useful skill a credit buyer can learn.

The legal landscape for ocean carbon claims: where greenwashing exposure comes from, how regulators and courts are acting, and how to reduce risk.

How economists put a value on kelp forests — the methods, the ranges, the honest caveats, and how valuation actually changes coastal decisions.

If two parties claim the same tonne of carbon, the atmosphere loses. Here is what double counting is, why Article 6 exists, and what buyers should check.

How ocean CDR field trials actually get permitted: research exemptions, environmental review, discharge rules, marine consent and community engagement.

Ex-ante credits sell carbon sequestration before it happens — how the instrument works, the delivery risks, and the safeguards buyers should demand.

Which carbon standards can actually issue kelp and seaweed credits today, where the methodology gaps are, and the due-diligence questions buyers should ask.

Beyond mangroves lies the frontier of blue carbon: kelp export, seabed sediments and ocean alkalinity. What buyers should know about early-stage credits.

Most corporate emissions hide in the value chain — and many value chains touch the ocean. How scope 3 accounting handles seafood, shipping and ocean removals.

Ocean alkalinity enhancement is a leading candidate for durable ocean carbon removal. How it works, what it might store, and the questions still open.

A clear-eyed framework for deciding when offsets are defensible: reduce first, then judge credits by integrity, permanence, additionality and claims.

Article 6 of the Paris Agreement sets the rules for trading carbon between countries. Here's how the rulebook reaches coastal and ocean projects.

Digital MRV — satellites, drones, acoustics, eDNA and machine learning — is collapsing the cost of verifying coastal carbon. Here's what works and what doesn't.

Adding alkalinity near kelp forests could store carbon and buffer acidification locally. What the chemistry promises, what ecology warns, and the safeguards that count.

Natural capital accounting puts ocean ecosystems onto balance sheets. What's counted, who counts it, and how it changes decisions about the coast.

Buffer pools are the insurance behind every credible kelp carbon credit. How they are sized, what a marine heatwave triggers, and what buyers should ask.
