Speaking on the occasion, the prime minister urged the students and youth to lead the campaign as it is connected with the future of the country.
Khan vowed to make the country "cleaner than Europe" in five years.
"For this to happen, we will also have to bring a change in our mindset," he said.
He pointed out that "plantation is imperative to protect the environment and check global warming".
Khan claimed his party's government had planted a billion trees in Khyber Pakhtunkhwa province.
He said his government has now set a target of planting 10 billion trees across the country which he said will change the weather pattern.
Khan said under the cleanliness drive, sewerage and sanitation systems will be improved not only in cities but also in slums and villages. He said as part of integrated solution, dumping sites would be identified from village to tehsil level for disposal of solid waste.
Khan said the country requires efforts from students to make Pakistan clean and green.
