FY27-28 VOLUNTARY LAWN AND GARDEN EMISSIONS 
REDUCTION PROGRAM WORK PLAN 
Mowing Down Pollution  
 
MARICOPA COUNTY AIR QUALITY GOALS AND PRIORITIES  
Maricopa County continues to experience an expanding residential housing market and 
therefore, the usage of lawn and garden equipment plays a notable role in the emissions 
profile of the County. Emissions from lawn and garden equipment are responsible for a 
considerable amount of all non-road emissions. Currently, the County is in non-attainment for 
ozone, for which the precursors are nitrogen oxides (NOx) and volatile organic compounds 
(VOC). According to the Maricopa County 2023 Ozone Periodic Emission Inventory, the lawn 
and garden equipment category accounts for 3.73% of all non-road NOx emissions and 35.60% 
of all non-road VOC emissions. The County was previously in non-attainment for carbon 
monoxide (CO) and 41.67% of nonroad CO emissions can also be attributed to lawn and 
garden equipment.

LAWN AND GARDEN EQUIPMENT AND TECHNOLOGIES  
According to the Environmental Protection Agency (EPA), approximately 121 million pieces of 
lawn and garden equipment are estimated to be in use in the United States of which, lawn 
mowers are the most numerous.1 The advent of new four-stroke mowers has created 
improvements in terms of efficiency as well as reduced emissions, however, older two-stroke 
mowers are still in operation and most lack any type of emission control technology. The 
replacement of gasoline powered lawn mowers with an electric equivalent will reduce the 
aforementioned pollutants as well as eliminate some of the indirect air pollution associated 
with maintaining and operating a gas-powered unit. The EPA estimated that approximately 
70,000 tons of gasoline was spilled in 2005 while refueling non-road equipment using 
portable fuel containers, which resulted in additional VOC emissions.2

Electric lawn mowers and other electric lawn equipment have come a long way in the past 
decade. Their rising popularity has motivated some of the more prominent manufacturers in 
the industry to develop cost effective options that are well within the budget of the average 
consumer. Technological advancements in lithium batteries have closed the performance gap 
between electric and gas-powered counterparts. Cordless options are also becoming more 
standardized, allowing for more user-friendly operations.  
 
ROLES AND RESPONSIBILITIES  
The Maricopa County Air Quality Department (MCAQD) will be responsible for the overall 
administration, management and implementation of the Voluntary Lawn and Garden 
Equipment Emissions Reduction Program in accordance with A.R.S §49-474.02.  MCAQD 
developed the program and launched it in June 2018 as the Mowing Down Pollution Program.  
Operations include data and document collection, financial management, outreach, necessary 
coordination for the retirement of replaced equipment, and providing progress reporting as 
described in the table below. In addition to allowing for the retirement of residential lawn 
mowers, A.R.S §49-474.02 also allows for the retirement of commercial lawn mowers and 
residential and commercial lawn and garden devices. Lawn and garden devices include leaf 
blowers, trimmers, edgers, and other similar equipment.  Commercial devices were added to 
the program in FY24.  All mowers and garden devices are recycled once turned in.   
 
The MCAQD director acts as the agent of the County for all emission reduction programs. 
Funds are managed by MCAQD finance team, which receives and processes invoices and 
payments. The program manager will review and confirm allocation of expenses and ensure 
deliverables align with the project scope and budget. All invoices will be reviewed and 
approved by the program manager.  Final authorization and the timely scheduling of payment 
will be completed by MCAQD’s finance team.

ANTICIPATED PROGRAM PARTICIPATION AND MILESTONES 
The Mowing Down Pollution Program focuses on decommissioning old lawn and garden 
equipment as well as facilitating the ownership of new and cleaner operating equipment. The 
promotion of the program continues on the MCAQD website. Program posts in both English 
and in Spanish are posted to social media sites.  Additional outreach occurs at regular 
outreach events where program flyers are distributed in English and in Spanish.  Additional 
commercial marketing is being explored. The program vendor is required to post program

FY27-28 PROGRAM BUDGET 
The remaining program voucher funding balance is estimated to be approximately $157,072 
at the end of FY26. For more efficient program budgeting, MCAQD is requesting that funds in 
the amount of $40,000 from the FY26 program be carried over into FY27 and extended 
through FY28. MCAQD will return the remaining amount after all FY26 vouchers are processed 
to the Arizona Department of Environmental Quality (ADEQ) within sixty (60) days after the 
end of FY26, resulting in a remaining project budget of $40,000.

MCAQD will continue to provide program outreach and management including associated 
costs.  ADEQ will continue to support the program by providing voucher funding per a signed 
agreement.  It is anticipated that the Service Agreement will be amended as needed to 
support the program.  MCAQD will continue to partner with additional county departments for 
mower/device collection and disposal.
