SQUAKE Launches CVP™: The Carbon Verification Protocol Advancing CO₂ Auditability in Business Travel

SQUAKE, the sustainability infrastructure provider for business travel, today announced the rollout of the Carbon Verification Protocol (CVP™): the first of its kind solution on the market - a production-grade system that makes business travel emissions fully traceable, immutable, and audit-ready.

CVP™ provides a uniform way to calculate, verify, store, and retrieve carbon emission values - ensuring every carbon figure in travel reporting can be defended with confidence and will be available via selected suppliers of the industry, from TMCs to OBTs and BI Tools.

“Credibility in sustainability starts with traceability,” said Philipp von Lamezan, CEO of SQUAKE. “With CVP™, companies can stand behind every ton of carbon reported - with proof.”

One problem, across the whole industry

Carbon figures are increasingly under scrutiny - from regulators, investors, and auditing bodies. But while emissions reporting is rising in importance, it remains broken in execution.

Same trip, different tools, different carbon emissions numbers. Methodologies applied inconsistently. No audit trails. No version control. No defensibility. Even when suppliers believe they are aligned, results differ and no one can explain why.

CVP™: Introducing the new foundation for CO₂ certainty

CVP™ changes that. Designed as an infrastructure protocol - not just a reporting tool - CVP™ is supplier-agnostic across the ecosystem to output consistent, audit-grade emissions data.

Each carbon emission value calculated under CVP™ is:

• Tokenized at the moment of creation
  
  
• Immutable and traceable back to aircraft, routing, factors and more
  
  
• Backed by a complete audit trail, versioned methodology, and metadata
  
  

Every partner issuing CVP™-verified values applies the same logic and passes conformity checks. No recalculations. No ambiguity.

Built for enterprise-grade auditability

CVP is built on six core principles:

• Compliance - Correct and consistent application of methodology
  
  
• Completeness - Full metadata capture per activity
  
  
• Immutability - Results are locked at creation
  
  
• Identifiability - Corporate-specific tokenization
  
  
• Tokenization - Each CO₂ value gets a unique verification token
  
  
• Accessibility - Tokens retrievable anytime, via API or file
  
  

These principles ensure that carbon data aligns with the same level of defensibility as financial data - and that audit readiness is embedded by default. The resulting data forms the foundation for implementing corporate reduction and removal strategies.

Already live across the ecosystem with selected launch partners

CVP is already in production with selected partners across global TMCs, booking tools, and corporates. It enables TMCs, booking platforms, and analytics tools to deliver consistent, trusted outputs - without reinventing their infrastructure. This is what some of the leading suppliers in the industry say:
