The Impact of Air Conditioning on the Environment

The Environmental Impact of Air Conditioning and Solutions for the Future

• Air conditioners have saved lives during heatwaves and made life in warm places more comfortable.
• The use of air conditioning contributes to global warming in several ways.
• Heating buildings still contributes more to climate change than air conditioning due to more people using heat for longer periods.
• Air conditioners burn fossil fuels and release CO2, contributing to global warming.
• Air conditioners move heat from inside to outside, pumping enough heat to warm an entire city by a few degrees.
• Air conditioners use chemical refrigerants that are thousands of times more powerful than CO2 at trapping Earth's heat, contributing to global warming.
• The use of air conditioning leads to a vicious feedback cycle that will worsen over time as more people have access to air conditioning.
• By 2050, four times as many air conditioners will be used as today, and at some point, more energy will be used for air conditioning than for heating.
• Solutions include using the most efficient air conditioners, generating electricity without releasing heat or CO2, and recycling or destroying refrigerants when getting rid of old air conditioners.
• Building designs that are naturally cooler, such as those with shiny white roofs, green roofs, and materials that absorb lots of heat in the walls, can help reduce the use of air conditioning.
• Redesigning cities to include more green spaces with trees that provide shade, encourage hot air to mix with cool air, and cool the air themselves through evaporation can also help.
• Researchers at the University of Minnesota, such as Professors Richard Graves and Bonnie Keeler, are working towards regenerative building designs that positively contribute to local communities and ecosystems.
