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. Collectors can start reporting GHG data on the WeRecycle Portal any time from now until the deadline of January 31, 2023.

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


The online resources available below can assist with compiling and reporting collection and post-collection GHG data:
