World Ozone Day

World Ozone Day
The Montreal Protocol started life as a global agreement to protect the ozone layer, a job it has done well, making it one of the most successful environmental agreements to date. A united global effort to phase out ozone-depleting substances means that, today, the hole in the ozone layer is healing, in turn protecting human health, economies and ecosystems. But, as this year’s World Ozone Day seeks to highlight, the Montreal Protocol does so much more – such as slowing climate change and helping to boost energy efficiency in the cooling sector, which contributes to food security.

Many ozone-depleting substances warm the climate, so the agreement has already slowed climate change. The Kigali Amendment to the Montreal Protocol is set to deliver even stronger climate benefits. Under the Amendment, nations have committed to phase down hydrofluorocarbons (HFCs). While HFCs don’t damage the ozone layer, these coolants are powerful greenhouse gases. Reducing their use, as agreed, is expected to avoid up to 0.4°C of global temperature rise by the end of the century, while continuing to protect the ozone layer.

The Kigali Amendment also provides an opportunity for improved energy efficiency in the cooling sector. New innovation replacing HFCs offers an opportunity to redesign air conditioning and refrigeration to use less power, allowing expansion of comfort cooling and cold chain efficiencies without increasing climate impacts. The combination of reducing HFC consumption and improved cold chain efficiencies, particularly in developing economies, will also combat food loss.

Around one third of all food produced globally for human consumption is either lost or wasted each year, largely due to a lack of access to cold chains. Food loss and waste amounts to billions of US dollars a year; not only wasting precious resources such as land, water and energy, but also generating an estimated 8 per cent of total greenhouse gases per year globally.

By developing cold chain solutions that are more efficient, more climate friendly, and cheaper to buy and operate, cold chains will become more effective and widely available. This will provide producers such as farmers and pharmaceutical providers with access to pre-cooling, refrigerated storage and refrigerated transport – ensuring products such as food and vaccines reach people in safe and good condition.

On this World Ozone Day, we celebrate and acknowledge the Montreal Protocol and its Kigali Amendment in its wider efforts to keep us, our food, and vaccines cool.
