The HFC Phasedown

What are HFC’s?

Hydrofluorocarbons (HFC’s) are potent, man-made greenhouse gases that have high global warming potentials. They are mainly used in refrigeration and air conditioning applications.

What is the global HFC Phase Down?

New Zealand was one of the 197 countries to adopt the Kigali amendment to the Montreal Protocol. The Kigali Amendment requires New Zealand and other developed countries to begin phasing down the production and consumption of HFCs.

What HFC controls does the amendment specify?

The Kigali amendment specifies an upper limit on HFC consumption. Developed countries are required to limit annual HFC consumption to within the upper limit.

When will the HFC phase down start?

New Zealand’s government ratified the Kigali Amendment on October 3, 2019. The phase down will enter into force January 1, 2020.

How will it be implemented in New Zealand?

The government has adopted more frequent and regular decreases in HFC consumption than those specified in the Kigali Amendment. The government will put a permitting system in place to set annual limits on imports and exports of bulk HFCs. Importers of bulk HFCs are required to surrender emission units to the government for all bulk HFCs imported.

How will the HFC phase down affect my business?

HFC Supply and Cost

New Zealand relies on importing supplies of HFC from abroad. The supply of HFC’s is at risk of reduction due to the phase down, which targets bulk HFC’s. Therefore, businesses face increased acquisition costs due to decreased supply. Supplies of R404A/R507 are especially under pressure. The phase out of R404A/R507 from all commercial systems Europe and the U.S. has been underway for several years.

Health and Safety Implications

HVAC and refrigerant industries are moving to alternative refrigerants in response to the global HFC phase-down. The common synthetic refrigerant alternatives to HFCs are more environmentally friendly, but flammable and toxic. This entails a significant shift in the knowledge and skills required of engineers and technicians in the industries, and health and safety implications for end users and obligations for directors.

New Skills and Technology

Many of the current systems are designed for phased down refrigerants which will become increasingly expensive and scarce. Going forward, service providers will need to demonstrate proficient skills and knowledge with new technology. New selection criteria for service providers will have to be developed.

Opportunities

Newly designed systems with alternative refrigerants offer the following positive implications for end users:

  • better system performance

  • lower energy use

  • lower operational costs

The industry-wide changes the phase down is bringing will present many opportunities savvy businesses can position themselves to exploit.
