Montreal Protocol

World grapples with refrigerant transition


A particular intercontinental publication has collected views from around the globe on the changeover to very low-GWP refrigerants beneath the Kigali Amendment. With the enable of neighborhood professionals, it reveals how the HFC phase-down is monitoring, the key challenges so much, and the likely solutions.

The Kigali Amendment aims to phase down HFC output worldwide by at least 80 for every cent in excess of the coming many years underneath the Montreal Protocol. The purpose is to cut down direct emissions of these gases due to the fact of their significant contribution to world warming – some HFCs are quite a few thousand instances far more powerful than CO2 as a greenhouse fuel. And quite a few of them are made use of in refrigeration and air conditioning machines.

If completely implemented, it is believed that the Kigali Amendment could avoid up to .5°C of world wide warming by the conclude of this century. So significantly, 141 nations have signed on to the agreement, such as, most not too long ago, the US. Some, like Australia, have currently been phasing down HFCs for a variety of yrs.

To provide an update on this worldwide energy, the Centro Studi Galileo (CSG) and the Renewable Energy Institute (REI), with assistance from the IIR, UNEP OzonAction and Space, have gathered experiences from all over the globe in a exclusive publication: Advancing Kigali Plans As a result of HVACR.

As very well as sharing views from distinctive nations around the world, it analyses broader problems around HVAC&R, these as instruction in new refrigerants, and attracting much more females to the business.

The journal was distributed at Chillventa, and is formally staying launched at MOP34 – the Thirty-Fourth Meeting of the Functions to the Montreal Protocol in Montreal.

The posts and the full publication can be accessed as a result of a focused web page.

US commits to HFC phase-down


The US Senate has ratified the Kigali Amendment to the Montreal Protocol, signing up for the 137 other nations that have by now ratified the treaty.

The Kigali Modification calls for a gradual reduction in the intake and manufacturing of hydrofluorocarbons (HFCs), which are strong greenhouse gases. A lot of of these are applied as refrigerants in HVAC&R methods.

“The United States is back again at the table main the combat against local climate adjust,” claims US President Joe Biden.

“As much more international locations be part of the United States in ratifying this amendment, we can prevent up to 50 % a degree Celsius of warming this century, a significant contribution to fighting local weather change and guarding communities from additional severe impacts.”

In accordance to the US State Division, environmental and small business communities strongly supported the US ratification of the Kigali Modification.

“[It] will enable to guarantee US business stays a world-wide chief in the development, production, output, and deployment of HFC alternate options,” claims the US Point out Division. “Industry estimates suggest that US ratification will guidance 33,000 new US production jobs and create $12.5 billion in new investments in the US financial state around the next decade.”

The transfer is also anticipated to give a improve for American businesses that have produced solutions to HFCs and approach to export technological innovation to abroad markets.

A lot more facts is accessible on the US Point out Department website.

Celebrating milestones on World Ozone Day


Entire world Ozone Day is getting celebrated on September 16 with the concept “global cooperation protecting existence on Earth”, in recognition of the 35th anniversary of the Montreal Protocol on Substances that Deplete the Ozone Layer.

On September 16, 1987, governments adopted the Montreal Protocol to manage and reduce ozone-depleting substances, largely chlorofluorocarbons (CFCs) and halons. The protocol came into outcome in 1989. By 2008, it was the first and only UN environmental arrangement to be ratified by every region in the earth.

“In the confront of a triple planetary crisis – local climate modify, character decline and pollution – the Montreal Protocol is one particular of the most effective examples we have of the ability of multilateralism,” claims Meg Seki, Executive Secretary of the United Nations Surroundings Programme’s (UNEP’s) Ozone Secretariat. She notes how this results is reflected in the theme for this year’s function.

In accordance to the UNEP Ozone Secretariat, the Montreal Protocol has shielded hundreds of thousands of people from pores and skin cancer and cataracts more than the many years. It has also slowed climate transform. If ozone-depleting chemical compounds experienced not been banned, it is approximated that global temperatures would rise by an additional 2.5°C by the conclude of this century.

The HVAC&R marketplace has played a big part in phasing out the use of CFCs, as very well as HCFCs, as refrigerants. In truth, in the final fiscal yr, Australia established a new report for destroying ozone-depleting refrigerant gases and getting rid of them forever from the ecosystem.

According to the Australian Refrigeration Council (ARC), the HVAC&R field ruined more than three occasions as substantially R22, a single of the most prevalent ozone-depleting refrigerant gases, as in any of the former five several years. Much more than 120 tonnes of R22 have been recovered in 2020–21 and despatched for destruction at the Refrigerant Reclaim Australia (RRA) plasma arc facility in Melbourne – the greatest sum because it started to be reclaimed for re-use a ten years back.

By distinction, destruction fees of R22 in the past 5 years ranged from 14 to 39 tonnes.

ARC chief government officer Glenn Evans says this a testament to the efforts of the full HVAC&R market, and to the legislation and rules that underpin the licensing scheme.

“This report coincides with the 35th anniversary of the Montreal Protocol on Substances that Deplete the Ozone Layer – a great accomplishment designed on prolonged yrs of dedicated energy,” he says.

“Australia enshrined the ideas of the Montreal Protocol in legislation with the Ozone Protection and Synthetic Greenhouse Gasoline Administration Act 1989 – 1 of the 1st countries to do so.

“The first targets to secure the ozone layer ended up the CFCs utilised in anything from aerosol cans to fridges and air conditioners, which were banned in 1996.

“After that, the RAC industry’s concentration moved on to doing away with hydrochlorofluorocarbons (HCFCs) these kinds of as R22, and below we are now, nearer than at any time to that objective.”
