Humanities & Social Sciences

The required minimum qualification for admission to a Ph.D. programme shall normally be a two years Masters or M.Phil Degree from any accredited Indian or Foreign University in the relevant field. She/he must have obtained 55% marks or Equivalent Grade in the master's.

As Physics and environmental studies are kind of different subjects:-
I think it is not possible ( Try asking your professors they might help )
1) M.Sc. Or M.Phil in environmental Science and other related fields. Those with M.Phil qualifications need not attend the entrance test but other postgraduates have to appear for both entrance as well as interview. It takes a minimum of 3-5 years to complete the programme.
2) candidates should have passed M.Phil. Degree and a Post-Graduate degree in a relevant discipline with a minimum of 55% marks or an equivalent grade from a University or a recognized institution of higher training.

Wait for the results to be out and plan for a master's degree.
