California mulls HFC bans in refrigeration, air conditioning from 2020-21

Date:

The California Air Resources Board has taken another step towards curbing emissions of high-GWP HFCs with the publication of a Proposed Strategy to reduce short-lived climate pollutants this week. The strategy foresees introducing a raft of measures, including bans on HFCs in stationary refrigeration and air conditioning with GWPs above 150 and 750, respectively. An anticipated budget of $20 million will incentivise the industry to shift to natural refrigerants.

The Air Resources Board is proposing actions to cut HFC emissions by 40% by 2030, compared to 2013 levels. Meeting these targets will help to achieve the Governor’s goal to cut all greenhouse gas emissions in California by 40% below 1990 levels by 2030 and help to meet Federal air quality standards for 2031 and beyond.

“The impact of these super pollutants is real and the fight against climate change must include a strategy to aggressively reduce them,” said California Governor Edmund G. Brown.

<strong>Key proposed measures to cut HFCs</strong>

Following the publication of the Concept Paper in May 2015, which was followed by a Draft Strategy and subsequent stakeholder comments, the Proposed Strategy includes the following key measures to address the use of HFCs:

A ban on the use of HFCs with GWP > 150 in new non-residential refrigeration (commercial and industrial) as of 1 January 2020;

A ban on the use of HFCs with GWP > 150 in new residential refrigeration as of 1 January 2021;

A ban on the use of HFCs with GWP > 750 in new air conditioning (residential, commercial, industrial) as of 1 January 2021;

Prohibiting the sale of new refrigerants with GWP > 2500 as of 1 January 2020 (recycled / reclaimed refrigerants would be exempt);

Financial incentives to help accelerate uptake of low-GWP refrigeration equipment, and;

Potential California-wide HFC phase-down in the absence of an international agreement in 2016.
<strong>Urgent action needed to avoid unnecessary cost</strong>

The Proposed Strategy notes that, “early action, ahead of some of the phase down schedules being proposed internationally, can avoid locking-in the use of high-GWP refrigerants in new or retrofitted systems in the coming years”.

“Without early action to reduce unnecessary emissions now and into the future, the State [of California] would need to take additional — likely more costly — steps to meet its 2030 climate targets,” the document reads.

Developing an incentive programme is particularly important to help the industry transition towards low-GWP refrigeration technology, such as CO2, ammonia and hydrocarbons. The Governor's proposed 2016-2017 budget includes $20 million for incentives to reduce HFC emissions from refrigerants. The paper notes that substantial progress has already been made regarding the safe use of natural refrigerants in North America and other parts of the world. For example, at least 300,000 HFC-free light commercial refrigeration units have been deployed in North America, with more than 250 stores using CO2 systems and over 250 ‘next-generation’ small-charge ammonia industrial refrigeration systems.

In addition, the paper points out that “switching to low-GWP refrigerants can also improve the energy efficiency of refrigeration and air conditioning equipment, which can help to cut electricity bills throughout the State”.

<strong>Interested in discussing California’s HFC reduction measures?</strong>

The California Air Resources Board is organising a public workshop on the Proposed Strategy on 26 April, before presenting it to the Board on 19 May. Comments by interested stakeholders will be accepted until 26 May.

The Final Strategy will be presented to the Board for a vote in autumn 2016.
