Banned refrigerants called CFCs are being cleaned up and recycled to help offset climate change. The refrigerants were banned decades ago as part of the Montreal Protocol due to the extremely destructive effects they carry with them. The voluntary carbon market has allowed private companies in countries with more resources to travel to countries like Ghana and Costa Rica to transport the CFCs, clean them, and offset their carbon footprint on carbon markets.

A collaborative effort among the United Nations' District Energy in Cities Initiative, the Malaysian government, and various private partners has raised awareness and facilitated planning in Malaysia's rapidly developing southern state of Johor for a "District Energy System": a single heating and cooling network which decreases energy consumption by converting waste heat from large power stations. Because of this intervention, Iskandar is projected to decrease its energy use by almost 40% -- all while saving money on energy costs, recycling heat energy, and contributing to the nation's goals under the international Paris Accord.

To prolong the shelf life of mangos, a cash crop in Kenya, members of the Masii Horticultural Farmers Cooperative in Machakos County have found a way to build innovative coolers that will work without a need for electricity. Although not without problems, like the ability for the farmer's to actually transport their fruit to the coolers, this innovation has allowed the deterioration process to stall for more than 15 days.

Inventors have come up with energy-efficient refrigeration options. A fridge uses water and ice to protect vaccines in places with irregular access to electricity. An engine that runs on liquid nitrogen reduces fossil fuel dependence in food shipping.

A recycling plant in Telford, England has found a way to recycle old refrigerators into new ones using a new technology that preserves the plastic without contamination from the refrigerator coolant. Usually, recycled refrigerator materials can only make simple products, like plant carriers; now, new technology can reduce the waste created from thrown-away fridges.
