Howard County has reportedly reached a significant milestone in its environmental efforts by reducing its greenhouse gas (GHG) emissions by 26 percent, indicating a steady progression towards its goal of a 60 percent reduction by 2030. The Office of Community Sustainability's "HoCo Climate Forward: 2025 Annual Report," which was released by County Executive Calvin Ball, underscored the acceleration of reduction efforts with an increased annual rate of GHG emissions reduction from 2.7 to 3.7 percent based on the latest data. "Although we are making great progress towards reducing our community’s carbon footprint, now is the time to double-down on our efforts to reach our 2030 target and become net zero by 2045," Ball emphasized in a statement obtained by Howard County.
Since 2019, the county has seen nearly a quadrupled annual reduction figure, up to 3.7 percent, from a lackluster 1 percent in the preceding years. The trajectory looks promising, but to achieve its climate goals, the annual reduction rate must accelerate to 4.8 percent. In December 2018, having taken office, Executive Ball's administration has been proactive in implementing initiatives that range from bolstering energy efficiency to increasing tree plantings.
Notable achievements include a significant 23 percent increase in solar capacity, resulting in a total of 150 MW as of June 2025. Transportation is another major focus, with the Regional Transit Agency of Central Maryland achieving a one-million-trip milestone, ahead of schedule by five years, and Howard County surpassing its EV adoption goals with five percent of registered cars being electric or plug-in hybrids. Additionally, the "Feed the Green Bin" curbside food scrap collection program has expanded to over 10,000 homes, contributing to a notable reduction in carbon emissions.
Several nature-based climate solution benchmarks were surpassed alongside infrastructure improvements aimed at reducing the county's "urban heat island" effects, such as planting 300 native street trees in targeted areas. With grants such as the $24,000 from the Maryland Energy Administration’s Resilient Maryland Program, Howard County also ensures that its emergency preparedness strategies are aligned with sustainable practices. Not only trees, but Howard County has also witnessed the county plant over 46,800 trees across 107 acres, driving forward the goal of a 50 percent tree canopy coverage by 2030.
