The 1987 Montreal Protocol

The Montreal Protocol is a global agreement to protect the ozone layer by controlling, reducing and ultimately eliminating global emissions of Ozone Depleting Substances (ODS). A binding time-frame for ending production, consumption and trade of ODS.

Singapore has been a party to the Montreal Protocol on Substances that Deplete the Ozone Layer since 1989. ODS controlled by the Montreal Protocol are regulated by NEA under the EPMA & EPM Regulations. As an Article-5 Party to the Montreal Protocol, Singapore is obliged to implement control measures to freeze the consumption of HCFCs on 1 Jan 2013 and to completely phase out HCFCs by 1 Jan 2030.

*HCFCs stands for hydrochlorofluorocarbons

The Phase-Out Plan and its implication to Aircon Refrigerant used in Singapore’s Residential Aircon

Starts off with R22 Refrigerant Gas. As such aircon using R22 are no longer being produced for the Singapore market and the import of R22 to Singapore will be ban by 2030.

The implementation of the next phase has been put in place. R410A will follow suit and aircon using R410A will no longer be produced for Singapore come 2022 and eventually the import of R410A to Singapore will be come to an end as well.

The future looks like a single-component refrigerant called R32. It is said to only have one-third the global warming potential as its predecessor R410A.

To anyone shopping for an aircon system today

Refrigerants give the air conditioner the power to cool your home, but when shopping for a new aircon system, many tend to overlook the refrigerant used, while focusing on the aircon features and energy efficient. No doubt, features & efficiency levels are easier to compare between the different manufacturing brands.

But the type of refrigerant used in the aircon should be put into consideration as well. With its predecessors being ban, aircon using R32 will be dominating the market soon. So, you could future proof yourself while playing apart for our environment by going for the R32 Aircon.

The 1987 Montreal Protocol’s phase-out plan gives home and business owners the option to switch to chlorine-free refrigerants once it was time to replace their current aircon system. But when import bans come into place those refrigerants would become scarce and very expensive.

To those using an aircon system running on R22

R22 is in the past. The future is green, and it comes with using the greener gas. Aside from doing your part to save the planet there are other benefits to upgrading your aircon system.

  • Lower running costs
  • Higher efficiency
  • Reduced carbon footprint
  • Convenience with smart technology
  • Increased value of your home
  • Better temperature control
  • Better air quality in the home
