World Ozone Day: Carrier Celebrates ‘Ozone for Life’
World Ozone Day
On Sept. 16, the United Nations recognizes World Ozone Day to celebrate the global ozone layer.
The ozone layer shields the planet from most of the sun’s harmful ultraviolet radiation and helps enable life on Earth. When scientists discovered “holes” were compromising this protective shield, the world’s governments took action and adopted the Vienna Convention for the Protection of the Ozone Layer. Under the Convention’s Montreal Protocol, governments, scientists and industry vowed to work together to greatly reduce the production of ozone-depleting substances.  
This year marks 35 years since the signing of the Montreal Protocol, and the 2020 World Ozone Day theme – ‘Ozone for life’ – reminds us that that we must continue to protect the ozone layer for future generations.
Carrier has long been an industry-leader in creating products that matter for people and planet, including the ozone layer. We continue to find solutions to help leave a healthier planet behind for future generations.
Carrier was a leader in the industry in phasing out ozone-depleting refrigerants more than 20 years ago. Balancing environmental protection, energy efficiency, safety and commercial viability, we helped push the boundaries of science and innovation to use non-ozone depleting and low global warming potential (GWP) refrigerants. Important innovations in Carrier’s HVAC segment include:
  • The award-winning Carrier AquaEdge® 19DV chiller that uses ultra-low GWP refrigerant, lowering energy consumption and reducing carbon dioxide (CO2) emissions throughout its life cycle.
  • Carrier AquaForce® with PUREtec™ refrigerant that has a GWP of less than one, delivering energy efficiency gains and reducing greenhouse gas footprints.
In its Refrigeration segment, Carrier has been building its portfolio of systems using the natural refrigerant CO2, which is non-flammable, non-ozone depleting and has a GWP of just one, which is thousands of times lower than many traditional refrigerants. Carrier is literally using CO2 to help reduce CO2
  • In the marine sector, Carrier Transicold’s NaturaLINE® container refrigeration system was the first in the world providing refrigeration using CO2, reducing CO2 emissions by up to 28% compared to previous equipment.
  • In the commercial refrigeration segment, Carrier introduced its CO2OLtec® system in 2004, and today more than 10,000 of these CO2 systems are in use in supermarkets across Europe and Asia. 
Today, thanks to the Montreal Protocol, the ozone layer is healing and expected to return to pre-1980 values by mid-century. Encouraged by this progress and eager to help solve the world’s challenges, Carrier continues to innovate to help create a healthier future – one that includes ‘Ozone for life.’
