Speaking to IRNA, Ebtekar said the sanctions have caused delays in Iran's plans for improving standards of fuels being used by vehicles in the country.
However, she said that the sanctions have encouraged Iranians to work harder to remove obstacles so that they have made major achievements in improving environmental standards.
"Now, Iran is capable of producing euro-4 fuel which is being distributed and used in metropolitans, including Tehran, Arak, Karaj, Tabriz and Isfahan," Ebtekar said.
Referring to the significance of climate change, Ebtekar said: "What we do in Iran have global effects."
