The Government of Macau revealed today that carbon emissions dropped by 59,167 tonnes in 2025, thanks to the increasing number of electric vehicles and the promotion of solar energy and natural gas. This reduction is “equivalent to the annual absorption capacity of 2.95 million trees,” indicated the Environmental Protection Bureau (DSPA) in its annual report on the state of the environment in Macau.
The report stated that the number of electric vehicles registered in the territory in 2025 increased by 34.6% compared to the previous year, totaling 16,339 units.
According to the document, among the new vehicles registered in 2025, the proportion of electric vehicles rose by about four percentage points since 2019, reaching 38.5%. The number of electric mopeds and motorcycles increased about 16 times “compared to the year prior to the launch of the financial support scheme,” which began back in 2022 to subsidize replacing obsolete motorcycles.
Furthermore, the percentage of citizens who chose to purchase electric motorcycles increased from approximately 2% to 36.8%, the DSPA added.

In 2025, the total number of motorized vehicles in Macau was 254,393, representing an increase of 0.5% compared to 2024, while vehicle density was 509 vehicles per kilometer, down 1.5% from the previous year. Additionally, solar photovoltaic energy systems were installed in three public housing buildings on a new artificial island, known as Zone A, near the Taipa passenger maritime terminal, and at the Lam Mau wastewater treatment plant.
In 2025, more than 87% of Macau’s electricity was purchased from mainland China.
The remainder of the electricity, nearly 13%, came from local electricity production within the territory. “With a view to further promoting carbon reduction works, in 2026, the Government will increase the percentage of clean energy to be supplied to Macau to 50%,” the bureau added. Last year, the region spent around 2.19 billion patacas (233.3 million euros) on environmental protection, representing 2.2% of total public expenditure, in order to protect Macau’s environment.
