New Zealand is today taking action to reduce the potent global warming hydrofluorocarbon (HFC) gases, Climate Minister
James Shaw and Associate Environment Minister Eugenie Sage announced today.
“The global agreement to reduce these potent greenhouse gases is another step in New Zealand’s commitment to reduce
global warming. It is estimated that this will avoid 0.5 degrees of warming by the end of the Century,” said Minister
for Climate Change James Shaw.
The Kigali Amendment, which New Zealand ratified today in New York alongside a number of countries, is an international
agreement to reduce the levels of hydrofluorocarbon (HFC) gases in the Earth’s atmosphere.
“These gases are a major source of global warming. It’s estimated that if Kigali is successful it could avoid warming of
up to 0.5 degrees by the end of the Century.
“This is major news for achieving our commitments under the Paris Agreement to cap global warming to 1.5 degrees” said
The Environmental Protection Authority (EPA) has been leading the implementation of the Kigali Amendment for New
“I’m proud of the work that the Environmental Protection Authority has been leading to implement the agreement. The EPA
is introducing a new permitting scheme which applies to all bulk imports and exports of HFC gases,” said Associate
Minister for the Environment Eugenie Sage.
HFCs, which are commonly used in refrigeration and air conditioning, were developed to replace other gases banned by the
1987 Montreal Protocol. The Montreal Protocol has resulted in a significant rebuilding of the Earth’s crucial ozone
layer, with projections of up to 2 million fewer skin cancer cases by 2030.
“However, since its introduction, science has since shown that HFC gases – which replaced those banned by the Protocol –
are potent greenhouse gases. HFCs capture heat from the sun and release it into the Earth's atmosphere – in some cases
up to 14,800 times more so than carbon dioxide,” said Eugenie Sage.
“The Kigali Amendment to the Montreal Protocol commits industrialised and developing member countries to reduce their
HFC production and use over time.”
The EPA has been working with users of HFCs, who will over time be required to phase down their imports in accordance
with targets set by the Ministry for the Environment. Ratification is the final step for New Zealand’s implementation of
the Kigali Amendment.
“By 2036, HFC consumption will be 85 per cent less than in 2020,” concluded Eugenie Sage.
