White Paper: Accelerating the transition to climate and environmentally friendly reefers

This document outlines the urgent need to transition maritime reefer containers toward climate-friendly refrigerants such as propane (R290) and CO₂ (R744). Despite clear environmental advantages, adoption remains limited due to regulatory, technical, and financial barriers. The publication highlights four key enablers for this transformation: technology development, regulatory support, capacity building, and financial mobilisation. Developed by the Kuehne Climate Center and the GIZ-implemented Greener Reefers project, the white paper provides a roadmap to significantly reduce emissions in the cold chain sector and align with global climate goals.
