Montreal Protocol and Paris Agreement
The origins of World Ozone Day (WOD) come from an international treaty signed in Montreal, Canada in 1987 that would see the phasing out of the production of substances that are responsible for ozone depletion. You can view the full list here .
This phaseout of ozone depleting substances over the past 30+ years such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons which all destroy ozone in the stratosphere, has helped to protect the ozone layer and slowed down the effects of climate change, whilst protecting human health and ecosystems. In 2009, a scientific article published in the PNAS journal noted that the Montreal Protocol has averted more than 135 billion tonnes of carbon dioxide equivalent emissions going into the atmosphere, thus significantly contributing to the mitigation of climate change .
Despite the progress made and scientific assessment acknowledging that the ozone layer is healing from damage inflicted upon it decades ago, the battle must continue to be fought by us all.
More recently, the Paris Agreement of 2015 saw nearly every country around the world enter into a legally binding commitment to reduce emissions to limit global warming to well below 2 degrees, and ideally to 1.5 degrees above pre-industrial levels. In November this year, leaders from all over the world will convene in Glasgow for the United Nations’ COP26 (Conference of the Parties and the 26th such event) to accelerate action on the agreement.
Culligan’s commitment to the cause
At Culligan we are committed to the responsible use of natural resources, continual development of clean technologies and the replacement of harmful substances with eco-friendly alternatives. In 2017 we made the switch to using the natural refrigerant gas R600a in our water dispenser compressors as an environmentally friendly refrigeration solution.
