Historically, humanity has had a greater need for space heating than space cooling. However, our global analysis shows that the need for cooling will overtake heating in the next decade – the exact year depends on what indoor temperature is chosen for comfort and health.
In the past 40 years, these changes have been driven by increasing temperatures, but also increases in population in warmer parts of the world. However, at present, millions of people don’t have access to heating and cooling or can’t afford to run it, leaving them to suffer uncomfortable, unhealthy temperatures. Providing zero carbon cooling is essential to avoiding more carbon emissions and making global warming even worse.
