Merida, Yucatan — More than 1,200 public buses and vans must be replaced to reduce air pollution emissions, said Aref Miguel Karam Espósitos, of the Yucatan Metropolitan Coordination agency (Comey).
But only 200 to 300 are replaced every year, the official admitted.
The average bus or combi is 10 years old, he said, declaring a challenge that must be met in the coming years. Higher maintenance costs is another reason to start replacing them, he said.
Most operate on diesel fuel; none are electric powered.
“All units generate polluting emissions, so it is necessary to review a way to incorporate new technologies that help reduce these gases that are harmful to health,” he said.
He also said that the agency is evaluating which units need to be replaced immediately. As for the investment that this change requires, he said that it is difficult to give a figure.
