Lawn & Garden Emission Reductions Strategy

The Regional Air Quality Council conducted stakeholder process during 2023 to develop a Lawn & Garden emission reduction strategy and received the RAQC Board endorsement of the proposal. The proposed regulation and supporting documentation below were submitted to the Air Quality Control Commission, culminating in a rulemaking in December 2023 to enact Regulation 29.

The RAQC’s proposal and the adopted regulation address Lawn & Garden emission controls to reduce ozone for nonattainment area planning efforts to reach compliance with National Ambient Air Quality Standards during the 2024-26 time frame, as well as to reduce greenhouse gases and toxic air contaminants. The adopted updates to the regulation restrict the use of small hand-held gas-powered lawn & garden equipment by public entities during the summer starting in 2025. More information and tools related to the regulation’s requirements are available on the Colorado Department of Public Health and Environment’s website.
