02/2026 Publication - Event DocumentationWebinar on Innovation in Cooling - Technologies without refrigeration gases
The way we think about cooling is changing — and with it, the technologies that shape our future. In a world facing rising temperatures and increasing pressure to reduce emissions, innovative approaches to cooling are more important than ever. This webinar opened new horizons by exploring solutions that deliver thermal comfort and efficiency beyond conventional refrigerant gases.
02/2026 Publication - Event DocumentationGreener Reefers: Cutting Costs and Emissions in Global Cold Chains
The global cold chain relies on refrigerated containers to keep fresh products moving across continents. The Greener Reefer Transition Alliance developed a simulation tool that helps shipping companies and cargo owners comparing synthetic and climate-friendly systems using natural refrigerants, across real trade routes, showcasing how greener choices can not only reduce emissions but also be the better business choice.
02/2026 Publication - ReportHotel Pilot Shows How R290 Cooling Cuts Costs and Emissions
To assess the potential benefits of climate-friendly cooling, a pilot project was implemented at the True Blue Bay Resort in Grenada, comparing conventional R410A air-conditioning units with highly efficient R290 (propane-based) units. The pilot demonstrates the technical, economic, and climate benefits of transitioning to energy-efficient air-conditioning systems using ultra-low-GWP refrigerants.
11/2025 Publication - Event DocumentationGreen Cooling Webinar #5: Green Heating and Cooling
Natural refrigerants have powered cooling and heating systems for decades — from food and beverage production, cold storage, and pharmaceuticals to industrial processing, commercial HVAC, and beyond. Their performance in Europe and elsewhere proves they can deliver high energy efficiency with zero ozone-depleting potential and no global warming potential (GWP). As global energy systems decarbonize, natural refrigerants such as ammonia, CO₂, and hydrocarbons are emerging as the future-proof backbone of sustainable heating and cooling.
11/2025 Publication - Event DocumentationMOP37 Side Event Recap: Driving the Transition for Sustainable Change in Mobile Air Conditioning (MAC)
Insights from Costa Rica & South Africa and the GIZ Greener Reefers project
This session discussed and demonstrated technological alternatives using natural refrigerants based on experiences from the Greener Reefers project in Costa Rica and South Africa and opened the floor for discussing the possibilities for the MAC sector.
05/2025 Publication - ReportGuide for Formulating Initiatives to Reduce Greenhouse Gas Emissions for Cooling Systems and Air Conditioning Projects in Colombia's Retail Sector
The GIZ Proklima program, in collaboration with the Ozone Technical Unit (UTO) of the Ministry of Environment and Sustainable Development (MinAmbiente) and the Green Cooling Initiative III project, developed this document, which is particularly relevant to the retail sector in Colombia.
05/2025 Publication - Guide / ToolGood Practice Guide for Commercial Refrigeration with Hydrocarbon Refrigerant R-290
This guide was developed by GIZ Proklima as part of the Green Cooling Initiative III project in Colombia. The Ozone Technical Unit (UTO) of Colombia's Ministry of Environment and Sustainable Development actively participated in its development. The UTO played a key role in shaping the publication's objectives and approach.
04/2025 Publication - Short Information MaterialWhite paper for immediate steps for a sustainable future
Natural refrigerants like propane (R290) present a unique opportunity for the reefer industry to cut emissions, meet global climate targets, and drive sustainable innovation. A new white paper by GIZ and the Kuehne Climate Center outlines how the transition can succeed – and highlights four key actions for a future-proof, climate-friendly cold chain.
