ThisIsCool Challenge winners

#ThisIsCool Youth Innovation Challenge winners announced at COP27


In 2022, SEforALL issued a challenge to youth working on sustainable cooling. We asked: What is your proposed technology or policy initiative to accelerate access to affordable and sustainable cooling?

We were looking for youth-led sustainable cooling solutions that can help deliver on one of more of the three cooling needs: 

  • Human comfort and safety: passive or active personal, space or urban cooling
  • Food, nutrition and agriculture: agricultural cold chain
  • Health services: vaccine and medical cold chain

We received close to 100 entries, with around 70 percent coming from Africa and about 20 percent from Asia – each vying for the top prizes of USD 10,000, USD 3,000, and USD 2,000 from Sustainable Cooling for All to support the implementation of their idea, provide visibility and incubation support.

On Youth Day of COP27, we invited the representatives of the #ThisIsCool Youth Innovation Challenge winners to the SDG7 Pavilion to present their innovations in front of a live and online audience.

Find out more about the three winners and their innovations:

Solar Freeze offers post-harvest solutions for small-scale farmers. The affordable solar cold storage rooms and IT solutions help prevent food waste and increase the farmers' income. These cold rooms are made of used shipping containers and use an innovative and efficient forced-air evaporative cooling system. They can be either fully owned and operated by the local communities through micro-franchising or used based on an affordable pay-as-you-store model.

Solar Freeze has participated in mentoring and training 100 young women aged 18-29 years through a program called "Each One, Teach One - Train to Earn", where rural youth learn how to operate and repair the Solar Freeze units.

Miti Mitaani ("Trees in our Neighbourhood") is a social enterprise at the forefront of mitigating climate change and fighting excess heat in cities with urban trees. Trees are an affordable, accessible cooling solution that reduces the ambient temperature up to 8 degrees and helps fight climate change.

Miti Mitaani combines climate intervention with livelihood creation. It provides viable work for low-income youth in urban centres and training on ecological best practices. In a pilot launched in August 2022, youth groups earn a monthly income based on the number of trees planted and the survival of those trees. The pilot's goal is to refine the program design to scale this intervention to more groups and other cities.

The Smart Cold Chain Monitoring System uses innovative tracking technology to prevent post-harvest food and pharmaceutical waste. It consists of a smart sensor device that records temperature, humidity, particulate matter, and location during cold chain transit and communicates the data in real-time. Users can place the device in vehicles, shipping containers and cold storage rooms. 

The company currently operates in Nigeria and plans to expand throughout Africa.
