Environmental development in Indonesia is based on the principle of sustainable development, where the environment is maintained for the benefit of present and future generations. The Indonesian economy growth for the welfare of citizens affects the environment, while economic development inevitably affects changes in natural and environmental conditions. Changes in natural and environmental conditions must be regulated through laws and legal acts, so that they can be utilized for the welfare of citizens without damaging the ecology. This study uses normative legal research, namely analyzing Law No 32 of 2009 on “Environmental Protection and Management”. Legal guarantees from the government are particularly important to prevent ecological damage due to the excessive exploitation of Indonesia’s natural resources, which negatively affects the environment. Therefore, the efforts made by the government to reduce ecological risks with sustainable environmental development policies are the best solution to this problem.
