The Taj Mahal draws thousands of tourists from India and overseas each year.
On Wednesday, the court expressed anguish over the Uttar Pradesh state government's failure to come out with a vision document to preserve and protect the Taj Mahal, which is located in Agra city in the state.
The government told the court that a special committee had been set up to suggest measures to prevent pollution in and around the monument.
It directed the Centre to furnish full details of the steps taken and action required to be taken for protecting the iconic monument.
The bench pointed out that no concrete steps have been taken by the government, despite a parliamentary standing committee report on Taj's protection. Taj Mahal has to be protected. Our Taj is more lovely.
The Centre told the Supreme Court that IIT Kanpur was assessing air pollution level in and around Taj Mahal and will give its report in four months. The Taj "is more lovely than the Eiffel Tower" and could have solved the country's foreign exchange problem, the judges noted.
The court has been hearing a plea filed by environmentalist M.C. Mehta seeking protection of the Taj from the ill-effects of polluting gases and deforestation in and around the area.
In May this year, the court had already instructed the government to seek foreign help to fix the "worrying change in colour" of the marble structure. "Do you realise the loss cost to the country due to your apathy?"
It has already shut down thousands of factories near the monument, but activists say the white marble is still losing lustre.
The Supreme Court declared it would hear the matter daily from July 31, in further indication of the seriousness it attaches to the Taj's preservation.
