Rogge, opening an IOC executive board meeting, said an "upbeat" progress report on Beijing would be delivered to board members on Thursday.
Pollution has been one of the main challenges facing Beijing Olympic organisers in a country where the environment has been victim of accelerated economic growth.
For the outside world, the human rights issue has also been a major concern and Rogge said the IOC was vigilant about the issue.
But he said he believed that the Olympics would have a positive effect on freedoms in the world's biggest communist state.
The IOC chief said that although it was not his job to monitor human rights in China, "we are listening to the specialised agencies and the NGOs who inform us."
"It is clear that the staging of the Olympic Games in Beijing will do a lot for the improvement of human rights and social relations in China. And it is not only me saying that," Rogge said.
