Carrier to Celebrate Environmental Milestone on Anniversary of Modern Air Conditioning

FARMINGTON, Conn. — On the 113th anniversary of Dr. Willis H. Carrier’s invention of modern air conditioning, Carrier will celebrate another milestone: 175 million metric tons of avoided greenhouse gas emissions since 2000 as a result of the installation of high-efficiency Carrier systems. This environmental achievement will be captured by the Carrier CO2NSERVATION Meter, which calculates avoided greenhouse gas emissions as a result of the installation of Carrier air-conditioning, heating and refrigeration systems around the world.

Dr. Carrier launched his world-changing invention on July 17, 1902 at Sackett & Wilhelms Lithography and Printing Company in Brooklyn, New York. Designed to provide humidity control, Carrier’s air conditioning system improved printing processes during the hot summer months. Since its launch, modern air conditioning has changed the indoor environment by creating productive, comfortable and safe climates to live and work in. Carrier continues to create products that improve quality of life while further enhancing energy efficiency and reducing environmental impact.

To highlight the environmental sustainability of Carrier’s energy-efficient products, Carrier introduced its CO2NSERVATION Meter in 2010. The meter calculates avoided greenhouse gas emissions of high-efficiency products from Carrier’s global portfolio using sales data to estimate the total products in use, and displays the total metric tons of greenhouse gases avoided or saved on a rolling meter. Since 2000, the avoidance of greenhouse gas emissions by Carrier products equates to nearly 37 million passenger vehicles removed from the road for one year or savings from eliminating electricity use from nearly 24 million homes for one year.

“As a sustainability leader, Willis Carrier invented precise cooling processes that enabled countless industries to avoid waste and preserve resources for future generations,” said John Mandyck, chief sustainability officer, UTC Building & Industrial Systems. “More than 100 years later, we honor his legacy with this fitting milestone on the Carrier CO2NSERVATION Meter, which demonstrates the power of choosing energy-efficient systems. We will continue to pioneer products that make our world a better place to live today and for generations to come.”
