Against a backdrop of rising temperatures, recurrent heat waves and droughts, demand for cooling networks in cities is set to become a major stake over the next few years. Demand already rose 3-fold between 1990 and 2016 and the International Energy Agency (IEA) has forecast it will rise 3-fold again by 2050. Urban cooling networks are then becoming key to facing climate change as the growth of urban areas shows no sign of slackening.
Cooling networks vs. air conditioning: the former are bound to prevail over the latter
Cooling networks are a win-win solution to ramp up city decarbonation all over the world. They make it possible to use greener fuels to cool buildings and the list of assets they generate for the comfort, health and well-being of city-dwellers is hard to challenge: they entail a 90% cut in cooling fluids compared with individual air-conditioning units and a 50% cut in electricity consumption and carbon dioxide emissions while allowing for a 97% improvement in energy efficiency.
In 2022, ENGIE’s yearly cooling-network supply reached 8TWh. In France, the Group is operating in such cities as Paris or Marseille; in Europe, it has cooling facilities in Barcelona, Lisbon or Berlin. In the latter case, ENGIE is developing a heating and cooling facility in a new eco-friendly neighborhood -”Das Neue Gartenfeld”. There are other such facilities around the world, in Dubai, Boston or Singapore where a cooling network is in its final stage of development.
To meet rising demand for cooling capacity, ENGIE is determined to build networks in France and all over the world. The Group will focus on setting up such cooling infrastructure next to client facilities to support their respective decarbonization policies. A further 8GW capacity will be added by 2035, compared with the 2020 baseline, 55% of which will come from heating and cooling networks, i.e. 4.4GW.

Climate change is now a driver of the world’s economy. The impact is profound:
- Catastrophic weather events — hurricanes, floods, droughts, high temperatures — are more frequent and more extreme. The cost can be measured in both the initial damage caused and the longer-term impact on the economy.
- Vulnerable communities are increasing climate-related investments, hardening infrastructure and taking other protective measures.
- Investment in carbon capture and storage technologies is increasingly rapidly.
- Governments are making investments and crafting regulations to reduce emissions of carbon dioxide and other greenhouse gases.
On top of all of this is the cost of uncertainty. As the Fourth National Climate Assessment, released in 2018 by the U.S. Global Change Research Program, says, “The assumption that current and future climate conditions will resemble the recent past is no longer valid.”
