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.

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.

11/2025 Publication - Event DocumentationMOP37 Side Event Recap: 30 Years of Promoting Natural Refrigerants

Visions and Lessons Learnt by the German Bilateral Cooperation
In this side event, we explained our approach and showcased examples of technology transfers in different refrigeration and air conditioning (RAC) subsectors around the globe, drawing on 30 years of Proklima’s experience. To discuss this we were joined by guest speakers Heidi Stockhaus (German Federal Ministry for the Environment, Climate Action, Nature Conservation and Nuclear Safety), Leslie Smith (NOU Grenada) and Federico San Martini (MLF Secretariat).

07/2025 Publication - Event DocumentationOEWG47 Side Event: Cool Tools for Cool NDCs

Irene Papst (HEAT) presented three mini modules that make reporting on mitigation action easier. Sandro Federici (Intergovernmental Panel of Climate Change, IPCC) explained new features in relation to calculating and reporting HFC Emissions in the IPCC Software.

04/2025 Publication - Event DocumentationGreen Cooling Webinar #1: R290 - A Sustainable Cooling Revolution

In this webinar, we leared how R290 can support climate action plans and contribute to global sustainability goals

11/2024 Publication - Event DocumentationMOP36 Side Event: Introducing Green Cooling in West and Central Africa

Experiences by the ROCA project
The project Refroidissement respectueux de l'Ozone et du Climat en Afrique de l'Ouest et Centrale (ROCA) promotes Green Cooling in Burkina Faso, Cameroon, Mali, and Senegal. It’s the first project in this region with a focus on natural refrigerants. In this side event, ROCA representatives presented results and lessons learnt of their work.

12/2023 Publication - Event DocumentationCOP 28 RAC Skills Side Event Highlights Philippine Innovation in Green Jobs through Climate-Friendly Cooling

The Philippines highlighted its best practice on green jobs in climate-friendly cooling through the COP 28 hybrid side event “Skills in Refrigeration and Air Conditioning with Growth in Global Cooling Demand” at the Philippine Pavilion on 08 December 2023.

12/2023 Publication - Event DocumentationCOP28: Greener Reefers – introducing climate and environmentally friendly maritime cooling containers

Around 3 million reefer containers are currently shipped around the world, and the number is growing annually. Reefer containers are vital for trading chilled and frozen products globally. On their journey however, reefer containers contribute notably to the emissions released by the container shipping industry (236 million tCO2eq. in 2018) and the reefer sector is projected to grow rapidly up to +8% p.a..
