Greenhouse Gas (GHG) Reporting

MMSW is required by its Stewardship Plan to track greenhouse gas (GHG) emissions associated with the program’s collection and recycling of residential waste packaging and paper.

The program’s Services Agreements with Collectors require annual operational data related to GHG emissions be submitted by January 31.

GHG reports for 2021 are to be submitted on the WeRecycle Portal by January 31, 2022. Collectors can start entering GHG data any time from now until the deadline.

Please reach out to MMSW’s GHG Team should you have any questions about GHG reporting:  or 1-855-886-4558 (option 4).
