Miami International Airport reduced greenhouse gas emissions by 4.4% from 2023 to 2025 as Miami-Dade invests in solar power, electrical upgrades and lower-carbon aviation infrastructure
Miami International Airport has earned Level 2 Airport Carbon Accreditation from Airports Council International, placing MIA among a small group of U.S. airports recognized for independently verified reductions in greenhouse gas emissions.
The designation comes as Miami-Dade County moves forward with billions of dollars in airport modernization projects that increasingly include energy efficiency, renewable power and other infrastructure intended to reduce MIA's environmental impact. According to the Miami-Dade Aviation Department, MIA reduced greenhouse gas emissions under its operational control by 4.4% between 2023 and 2025, falling from 102,789 to 98,275 metric tons of carbon dioxide equivalent.
The reductions were independently verified as part of the accreditation process. MIA received its Level 2 certificate during Airports Council International-North America's Annual Conference and Exhibition in Philadelphia on Sept. 16.
For Miami-Dade, the recognition is significant because MIA is not only one of the region's largest pieces of public infrastructure but also one of its most important economic engines. Reducing emissions while the Miami International Airport continues to accommodate substantial passenger and cargo activity presents a long-term challenge that will require changes to how the facility generates and uses energy.
MIA Pairs Carbon Reduction Goals with Major Infrastructure Investments
Airport Carbon Accreditation is a global carbon-management program developed specifically for airports. Level 2, known as Reduction, requires an airport to measure its carbon footprint and demonstrate that emissions within its control have declined.
Miami International Airport is one of only 15 airports in the United States with Level 2 accreditation, according to Miami-Dade County. The airport has established longer-term targets of reducing carbon emissions by 20% by 2035 and 50% by 2055.
“This elevated level of accreditation demonstrates MIA's leadership in environmental stewardship and its alignment with Miami-Dade County's clean energy strategy,” Miami-Dade County Mayor Daniella Levine Cava said. “It highlights how resilience and innovation improve daily operations through better tracking, better decisions, and greater accountability.”
Those goals are increasingly being incorporated into the airport's broader infrastructure plans. MIA is undergoing a $14 billion capital improvement program known as the Modernization in Action, or M.I.A., Plan, which includes improvements affecting terminals, baggage systems, parking, utilities and other airport infrastructure.
One component is a 20-year, $547 million tariff-based agreement between the Miami-Dade Aviation Department and FPL Services approved in 2023. The agreement calls for upgrades to MIA's electrical infrastructure, including solar power systems and electric vehicle charging stations.
The Miami International Airport has also begun incorporating lower-carbon alternatives into aviation itself. In 2024, partnerships involving DHL Express, World Fuel Services and Signature Aviation brought regular deliveries of sustainable aviation fuel, or SAF, to MIA. The airport described them as the first regular SAF deliveries in Florida.
Sustainable aviation fuel is intended to reduce lifecycle greenhouse gas emissions compared with conventional jet fuel, although the environmental impact varies according to how the fuel is produced and sourced. For an international aviation hub such as Miami, efforts to reduce emissions from aircraft operations represent a separate and considerably larger challenge than reducing emissions from airport-controlled buildings and infrastructure.
Solar Expansion Adds Another Piece to MIA's Modernization
MIA's next major renewable-energy project is expected to begin taking shape in early 2027, when the airport plans to add approximately 410,000 square feet of terminal roofing incorporating a solar photovoltaic system.
According to Miami-Dade County, the system is designed to generate nearly 900,000 kilowatts of electricity, which the county says would be enough to power as many as 7,000 homes. The project connects MIA's environmental targets with the extensive physical modernization already taking place across the airport.
That relationship matters because the airport is expanding and upgrading at the same time it is attempting to lower emissions. Earlier Calle Ocho News coverage examined how MIA's modernization has included passenger improvements, technology, terminal enhancements and other infrastructure projects as the airport responds to its growing role in South Florida's economy.
MIA generated an estimated $212 billion in statewide economic impact in 2025 and supported 945,682 jobs across Florida, according to an economic impact study previously reported by Calle Ocho News. The scale of those operations makes energy and infrastructure decisions at the airport consequential beyond the terminal itself.
Airport Carbon Accreditation includes seven certification levels ranging from Mapping to Maintenance. Rather than representing an end point, MIA's Level 2 status documents that the airport has established an emissions inventory and demonstrated reductions in emissions it directly controls.
For Miami-Dade residents, the larger question will be whether those reductions can continue as the airport modernizes and demand for aviation grows. The planned solar installations, electrical improvements and long-term carbon targets provide measurable benchmarks against which future progress can be evaluated.
MIA's latest accreditation establishes one such benchmark: emissions declined between 2023 and 2025. Maintaining that trajectory while one of South Florida's most important transportation and economic hubs continues to grow will be the next test.
