Paryavaran Mitra advocates for new policies and proper implementation of environmental laws. We have been instrumental in bringing some landmark judgment pertinent to environment which has strengthened public participation, increased accountability of government, and helpful in getting compensation to affected people. The Unique contribution of Paryavaran Mitra is in Public Interest Litigation (PIL) for more than two decades ensuring support and presence in all and one litigations of Gujarat. As a part of advocacy we influence government and judiciary in bringing effective legislation and policy change for sustainable development by using various means of advocacy like Right to Information (RTI), Media (print and electronic), judiciary, state assembly etc. Some of our case studies are given below.
