Carbon Markets
How carbon is priced, traded, and moved — from compliance markets to the voluntary market and the mechanics that keep them honest.
Carbon marketA carbon market is any system where the right to emit or the reduction of emissions is bought and sold as a tradable unit.Read guide →Compliance carbon marketA compliance carbon market is a regulated system where entities covered by an emissions cap must hold allowances for what they emit.Read guide →Voluntary carbon marketThe voluntary carbon market is where organisations and individuals buy verified carbon credits without a regulatory obligation.Read guide →Cap and tradeCap and trade is a policy design where a hard emissions limit is combined with trading of allowances to meet it at lowest cost.Read guide →Emissions trading systemAn emissions trading system is a regulated scheme that caps emissions and lets participants trade allowances to comply.Read guide →Carbon priceA carbon price is the cost attached to emitting a tonne of greenhouse gas or the value placed on avoiding one.Read guide →Carbon market liquidityLiquidity is the ease with which carbon units can be bought or sold without moving the price significantly.Read guide →Carbon offsetA carbon offset is a verified reduction or removal used to compensate for emissions occurring elsewhere.Read guide →Carbon market intermediaryAn intermediary in carbon markets connects buyers and sellers and often provides expertise, structuring and settlement.Read guide →Over-the-counter carbon marketThe over-the-counter carbon market is where buyers and sellers trade privately rather than on a public exchange.Read guide →Carbon market infrastructureCarbon market infrastructure is the underlying systems — registries, standards, verification and settlement — that let carbon be issued and traded.Read guide →Carbon market integrityIntegrity is the property that a carbon unit represents a real, additional, and non-duplicated climate benefit.Read guide →Carbon market fragmentationFragmentation is the splitting of carbon markets into many disconnected registries, standards and venues.Read guide →Carbon market transparencyTransparency is the availability of clear, reliable information about credits, projects and transactions.Read guide →Carbon market scalabilityScalability is the ability of carbon markets to grow in volume and participation while keeping quality high.Read guide →Carbon market accessMarket access describes who can buy, sell or hold carbon units and the barriers that limit participation.Read guide →Carbon price discoveryPrice discovery is the process by which a market arrives at the going price for a carbon unit.Read guide →Carbon market scarcityScarcity is the limitation of available carbon units that gives them value and drives abatement.Read guide →
