gryn

Core Features

The gryn platform is built around making fragmented logistics data usable for emissions management. It combines carrier engagement and data validation with standardized calculation, reporting and analysis, allowing shippers to move from estimated transport footprints toward more granular primary data.

• Logistics Data Collection: gryn consolidates shipment information from different logistics providers and other sources into a central dataset, reducing the manual work involved in assembling transport emissions information.

• Scope 3 Transport Emissions: The platform calculates and tracks upstream and downstream transportation emissions, including Scope 3 Categories 4 and 9, across multimodal supply chains.

• Supplier Engagement & Data Validation: gryn engages logistics providers to obtain emissions information, validates incoming data and helps companies increase their use of primary rather than modelled data.

• Compliance Reporting: Automated workflows support logistics emissions reporting aligned with ISO 14083, GHG Protocol and CSRD/ESRS requirements. Following its merger with Lune, the combined platform is also GLEC-accredited.

• Emissions Analysis & Reduction Planning: Users can identify carbon-intensive lanes, suppliers and other hotspots, set reduction targets and use emissions information to inform changes such as route, transport-mode and fuel choices.

• Logistics Insetting: A dedicated module lets users browse verified insetting offers by transport mode and fuel type and maintain third-party certificates in a centralized repository, connecting emissions measurement with logistics decarbonization measures.

Closing Insights

gryn was developed by Hamburg-based GRYN GmbH, founded in 2022 by Oliver Ritzmann. Its specialization is useful for companies whose carbon accounting challenge is not their entire corporate footprint, but obtaining consistent emissions information from numerous logistics providers. Customers named by gryn include adidas and PUMA reflecting its focus on enterprises that need to track transport emissions across global supply chains for reporting and decarbonization.

In January 2026, gryn merged with the supply-chain carbon intelligence company Lune. The merger combines gryn's automated logistics data collection and shipper-focused platform with Lune's emissions calculation technology for logistics service providers. Together, the businesses serve more than 100 customers and process data covering tens of millions of shipments globally. The combined platform is ISO 14083-compliant and GLEC-accredited. The combined company is gradually adopting Lune as its master brand, while gryn continues as the dedicated solution for shippers. This gives prospective users a useful distinction: gryn remains focused on helping cargo owners consolidate and act on logistics emissions data, while the wider Lune offering also serves logistics providers with embedded CO₂ intelligence.
