Voluntary carbon market
Voluntary carbon market is a market where participants buy and sell carbon credits outside a compulsory emissions trading scheme. Applying Voluntary carbon market requires a stated emissions scope, inventory boundary, baseline, energy system, and assessment horizon. Those choices determine how Voluntary carbon market can be compared or acted upon.
In simple terms
In practical use, Voluntary carbon market is a market where participants buy and sell carbon credits outside a compulsory emissions trading scheme. For Voluntary carbon market, its rules, eligibility conditions, incentives, prices, or financial terms must be tied to the covered activity within a declared emissions scope, inventory boundary, baseline, energy system, and assessment horizon. Voluntary carbon market connects with Carbon credit and Carbon capture and storage; each can affect its application without sharing its definition. The candidate link between Voluntary carbon market and Adaptation pathway remains a separate expansion question supported here by Integrity Council for the Voluntary Carbon Market.
Why it matters
Voluntary carbon market matters because decisions about it determine which emissions enter an inventory, which transition option appears credible, and how progress is compared over time. A defensible use of Voluntary carbon market therefore exposes its boundary, method, evidence, responsible actor, and uncertainty before a conclusion is accepted. That discipline keeps Carbon credit and Carbon capture and storage from being treated as proof of Voluntary carbon market when their criteria, scope, or results differ.
Example
An emissions and energy team evaluates Voluntary carbon market for a defined decision and records the relevant emissions scope, inventory boundary, baseline, energy system, and assessment horizon. For Voluntary carbon market, the team uses cited material from Integrity Council for the Voluntary Carbon Market to apply the instrument to the eligible activity or transaction, documenting the period, data, assumptions, and comparison with Carbon credit. It treats Carbon capture and storage and Adaptation pathway as separate questions rather than proxies for Voluntary carbon market.
How it differs
Carbon credit
Voluntary carbon market is a policy or financial instrument; Carbon credit has a different function. Evidence for Carbon credit does not establish Voluntary carbon market unless both sets of applicable criteria are met.
