World Ozone Day - 35 Years of Ozone Layer Protection

By Claire Baldwin, Communications Marketing Executive, September 2020

It was on September 15th 1985 that the Vienna Convention was adopted by the world’s governments. Under the agreement of the Montreal Protocol, global leaders set out to regulate the production and consumption of nearly 100 man-made chemicals referred to as ozone depleting substances (ODS) after scientists discovered that humanity was creating a hole in the Earth’s ozone layer.

This stratospheric layer shields Earth from most of the sun’s harmful ultraviolet radiation. The hole – caused by ODSs used in aerosols and cooling, such as refrigerators and air-conditioners – was threatening to damage human health, the environment, as well as the ecosystems which sustain the planet.

Thanks to the Montreal Protocol, the ozone layer is healing and expected to return to pre-1980 conditions by mid-century. In support of the Protocol, the Kigali Amendment, which came into force in 2019, will work towards reducing hydrofluorocarbon (HFCs); greenhouse gases with powerful climate warming potential and damaging to the environment.

World Ozone Day, held annually on September 16th, celebrates this achievement.

This year, we celebrate 35 years of global ozone layer protection and the collective decisions and actions that go into solving major global crises. This show of cooperation is more significant than ever during the Coronavirus pandemic as each one of us does our part to protect our friends and families.

What you can do

  • Wear sunglasses that filter out UV rays to protect your eyes from the sun’s glare
  • Avoid excessive sun exposure by using sunscreens with a high SPF rating of 30 or higher
  • Pay attention to the UV index, which indicates how high levels of UV radiation is on a daily basis
  • Take care of appliances in the home to minimize ozone layer impact
  • Dispose of appliances and equipment with refrigerants responsibly
  • Set the thermostat of your refrigerator and freezer to the right temperature
  • Ensure that air can easily circulate around the back of your refrigerator and freezer and clean them regularly to prevent them from overheating
  • Regularly service older equipment or replace products that aren’t CFC free where possible
  • Do not overstock your freezer
  • When buying new equipment, look for ‘ozone friendly’, ‘HCFC free’ or ‘energy-efficient
  • Insulate walls, doors, and windows to maintain an energy-efficient home
  • Keep rooms cool with ventilation to reduce the need for air conditioning
  • Switch your car air conditioner on after you have been driving for a few minutes
  • Park in the shade where possible to reduce the need for air conditioning

Nuaire’s Promise

Nuaire is dedicated to creating sustainable and energy-efficient products. We make the most out of what we’ve learned over 50 years of success, pioneering new air technology to bring you products that work whilst remaining conscious of our environment.

Every part of our business plays a role in managing sustainability and delivering on our promise to achieve zero-emissions. If all our electricity was produced by renewable sources today, our products would be close to zero-carbon already. Our role in this is to ensure that the products that we produce enable the healthiest environment to be maintained with the least possible energy usage. Health must be the priority.

Even today we are working on systems for homes designed to perform much better than building regulations require. Along with an adequately insulated home, an efficient mechanical ventilation system with heat recovery (MVHR) plays a major part in creating energy-efficient and environmentally sensible homes.

For our latest MVHR system, the MRXBOXAB-ECO 5, we use intelligent controls to link the response of temperature sensors to the operation of the ventilation unit. For example, we can automatically increase the air flow rates to provide additional comfort in summer, but also to prevent temperatures building up throughout the day.

The ECO 5 is also surprisingly compact for such a powerful system. The ECO 5 provides whole-home ventilation with heat recovery of up to 95% efficiency whilst taking up less room than a standard boiler. Installed into a cupboard out of the way, the ECO 5 can provide discrete, continuous ventilation.
