Cool Cont­ri­bu­ti­ons fight­ing Cli­ma­te Chan­ge II (C4 II)

Commissioned by: German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV)
Partner countries: Costa Rica, Grenada, the Philippines


The objective of the project is to foster sustainable development of the RAC sector by strengthening the competence of key actors and improving related structures. C4 II adapts existing methodologies and develops new tools for replication in other countries, promoting the transformation towards sustainable cooling. Increased ambition triggered by sector specific NDC implementation plans is expected to unlock enormous GHG reduction potential. 

Country specific objective

Cooperation with the three partner countries is twofold: Firstly, the countries will be supported in advancing and implementing the cooling strategies developed with C4 I assistance. Secondly, all three countries will serve as valuable sources of knowledge on cooling strategies, policy approaches and green cooling technology demonstration, which is highly relevant for an increasing number of third countries.  


A sustainable approach enabling a strong multiplier effect lies at the core of the project. Best practices and instruments developed in C4 I are to be made available to other countries for replication in blueprints and guidelines. This includes, for instance, a blueprint on sector-specific NDCs or a roadmap for the introduction of Minimum Energy Performance Standards. Proven approaches are to be systematically transferred to other regions, which in turn will increase awareness of Green Cooling.

Ad­van­cing Gen­der Main­strea­m­ing in the Ref­ri­ge­ra­ti­on and Air Con­di­tio­n­ing Sec­tor: Sharing Best Prac­tices from Gre­na­da

08.03.2024 , News :

The global project Cool Contribution fighting Climate Change II (C4 II) presented best practices in gender mainstreaming in the refrigeration and air conditioning (RAC) sector in Grenada at the “Regional Workshop for Women in Refrigeration and Air Conditioning”, which was held back-to-back with the “Thematic Network Meeting of the National Ozone Officers (NOOs) from the English-speaking Caribbean and Haiti” from 13 to 14 November 2023 in Trinidad.

Mr. Jiminy Scott, Junior Technical Advisor for the C4 II project in Grenada, presented on the efforts of the Grenada National Ozone Unit (NOU) in Grenada towards advancing gender mainstreaming within the RAC sector with the support of C4 II project. The Regional Workshop for Women in Refrigeration and Air Conditioning, organized by UNEP Ozone Action, provided a platform for female RAC technicians in the Caribbean Network to share their experiences.

Trai­ning Fe­ma­le Coo­ling Tech­ni­ci­ans

To facilitate Grenada’s switch towards Green Cooling, C4 II supports the training of RAC technicians in the safe use and handling of natural refrigerants. In 2022, the project trained the first two female refrigeration and air conditioning trainers from Grenada and Barbados at the Cool Training in Germany.

R290 de­mons­tra­ti­on pro­ject

In 2023, an all-female team of RAC technicians installed an R290 AC in the office of Grenada’s Minister of Climate Resilience, The Environment & Renewable Energy, Hon. Minister Kerryne James. Minister James expressed her desire to involve more women in the RAC sector and encourage them to consider careers in the STEM fields.

Gen­der sur­vey

During the 2023 Grenada Cool Training, a training on the natural refrigerant propane (R290), C4 II conducted an anonymous survey, in which participants expressed strong support for women entering the RAC sector.

Answers given by RAC technicians on the question: “What is your advice for women who are interested in joining the RAC sector?”

  • "It is an interesting field to work in for any gender and if one chooses to work in that field, they should."
  • "Stay focused, don't be intimidated, and go for what you want."
  • "My advice for women who are interested is to speak to women who are already involved with HVAC field to determine if that is what you really want to do."
