ECCC Publishes Final Revisions to ODS/Halocarbon Regulations Concerning Control of HFCs

Environment and Climate Change Canada (ECCC) published the final revisions to the federal ODS and Halocarbon Alternatives regulations concerning control of HFCs in Canada Gazette II on October 18, 2017. These revisions come into force 180 days after the date of publication in Gazette II (April 16, 2018).

The HFC phase down schedule in the regulations has been revised from the draft contained in the Canada Gazette I publication (November 2016), to bring the regulations in line with the terms of Kigali amendment to the Montreal Protocol. This amendment was adopted by the parties to the Protocol in 2016. The baseline HFC consumption quantity for Canada is 19,118,651 tonnes of CO2 equivalent. The consumption reduction schedule contained in the regulation is as follows:

90% in 2019
60% in 2024
30% in 2029
20% in 2034
15% in 2036

The second part of the regulation changes involves establishing limits on global warming potential (GWP) of refrigerants that can be used with industry systems and compliance dates for these limits. The limits and compliance dates are as follows:

1.      Stand-alone medium temp refrigeration systems  - 1400 (January 1, 2020)

2.      Stand-alone low temp refrigeration systems  -  1500 (January 1, 2020)

3.      Centralized refrigeration systems  -  2200 (January 1, 2020)

4.      Condensing Units  -  2200 (January 1, 2020)

5.      Chillers  -  750 (January 1, 2025)

6.      Mobile refrigeration systems  -  2200 (January 1, 2025)

The GWP limits for systems listed above under numbers 1, 3 and 5 were changed from the draft proposals published by ECCC in Gazette I in November of 2016. In each case, the allowable GWP level has increased.
