Bottom Line on Offsets

The document defines a greenhouse gas offset as a unit of carbon dioxide-equivalent (CO2e) reduced, avoided, or sequestered to compensate for emissions elsewhere. It outlines five essential criteria for environmental integrity: offsets must be real (representing actual reductions relative to a baseline), permanent (not reversible), additional (resulting from carbon market incentives rather than business-as-usual), verifiable (monitored by independent third parties), and enforceable (tracked via registries to prevent double counting). The text distinguishes between regulatory markets, where government agencies set standards, and voluntary markets, which rely on various independent standards for quality assurance. It notes that while offsets can support corporate emissions strategies after internal mitigation is maximized, future climate programs are more likely to recognize internal abatement over offsets.

• To ensure environmental integrity, offset credits must meet five specific criteria: they must be 'Real', 'Permanent', 'Additional', 'Verifiable', and 'Enforceable'.
• Additionality, the requirement that a project would not have occurred without carbon market incentives, is determined either through project-specific evaluations against alternative scenarios or through standardized criteria for specific project types.
• The offset market is divided into regulatory markets, where government agencies establish standards and structure, and voluntary markets, which lack a common standard and instead use various independent voluntary standards for quality assurance.
• Leading U.S. voluntary standards as of 2009 include the Climate Action Reserve (CAR), Voluntary Carbon Standard (VCS), Chicago Climate Exchange (CCX), American Carbon Registry (ACR), and The Gold Standard (GS).
