Why Rappel's GHG inventory is audit-ready and higher quality
Transparent foundation
Ensuring that your boundaries, material categories and assets, and data sources are clearly defined before any emissions are calculated
Market standard tools
Starts every inventory with a standardized inventory management plan (IMP) built on GHG Protocol best practices
❌ Skip this step or fill out a perfunctory IMP only after data is collected and emissions are calculated.
Rappel
Validated results
Flagging and adjusting for data errors before they get included in the measurement
Rappel
uses the power of CO2-AIM model to compare inventory data to a company’s operational realities.
Market standard tools
>90% of the inventories we use from other platforms need to be recalculated because company data has not been validated.
Flexible input
Tailored to your company’s data availability, not just an ideal structure
Rappel
Market standard tools
have sophisticated AI models to estimate emissions from bills, cost ledgers, telematics, and asset characteristics to use the best data available.
❌ Typical tools and services require primary activity data in rigid templates or default to generic estimates only.
Capability building + execution
Establishing cross-functional stakeholder buy-ins throughout the process
Rappel
Market standard tools
Ensures that teams are educated on the basics of GHG inventories and guided to best practice data sources, calculation methods, and process steps
