This seems like it should be straightforward. I need to cite a report on global warning conducted by the Department of environment
There are no authors associated with the report.
This type of report is very common so I;m surprised there isn't a bibtex format for it.

Re: How to cite a report from a research institution
I think you want the @TECHREPORT category; required fields are author, title, institution, year. Optional fields are type, number, address, month, note, key. For author you could fill in the department, all inside an extra set of {...}.
