I will try to answer, although I am not in the waste management aspect.
To give you some statistics, in Canada, methane generated by landfills has increased by almost 6% since 2005, from 970 kilotonnes to 1,027 kilotonnes, primarily due to the growth of population and the generation of degradable organic waste in municipal landfills.
That being said, the increase in methane generation has also been offset by an increase in the capture of methane in municipal landfills, from 32% to a total of 44% in 2016. A lot has been done due to the fact that provincial governments put in place regulatory requirements and measures that the major landfills have carbon capture mechanisms.
Government funding to support low-carbon initiatives also contributed to the reduction of landfill methane emissions, such as funding provided through the Federation of Canadian Municipalities, direct funding provided by the Government of New Brunswick, and Quebec's biogas program. Some landfills in Quebec and B.C. have generated carbon offsets in the California market as well.
Based on recent research conducted by our department, landfill gas capture systems are in place or under development at approximately 94 out of 130 of the largest landfills in Canada, and an additional 23 out of 149 medium-sized landfills that serve a population of 12,000 to 50,000.
This is the progress that has been made, so definitely there are good practices. A case in point is that the landfills that do not have capture systems have developed some, and for those that have capture systems, they've found ways to improve efficiency. There are definitely provincial and federal efforts to together help reduce the generation of methane in landfills.
