Background
In July 2010, the City of Raleigh developed the “City of Raleigh Greenhouse Gas Inventory: Municipal Operations”
report. The purpose of the inventory was to quantify emissions from municipal operations and to identify the
City’s emission sources for its operations. With respect to solid waste, the 2010 inventory included the collection
of solid waste within the City, which is under the direct control of the City.
The City’s solid waste is disposed in landfills that are owned and operated by Wake County. Solid waste
generated within the City is transported by the City to transfer stations. Wake County then transports the solid
waste from the transfer stations to its landfills. While Wake County has operational control over the disposal
activities, the City can directly influence the volume of solid waste disposed through the implementation of
policies, educational programs and choices of solid waste services offered to the community including recycling
and composting.
This Technical Memorandum (TM) presents a baseline greenhouse gas (GHG) emissions inventory for the disposal
of the City’s solid waste in Wake County landfills for the year 2007 and one subsequent year, 2010.
Inventory Boundary Conditions
Operational Boundaries
Greenhouse gas emissions are defined by the three categories shown below and as depicted in
Exhibit 1
.
Scope 1 - Direct emissions
Scope 2 - Indirect emissions
Scope 3 - Optional or other
indirect emissions
The year 2007 and year 2010
landfilled solid waste inventory
includes only Other Indirect
Emissions (Scope 3) because an
entity other than the City
(
Wake County) has operational
control over the disposal
activities.
