Environmental mitigation refers to the process by which measures to avoid, minimise, or compensate for adverse impacts on the environment are applied.[1] In the context of planning processes like Environmental Impact Assessments, this process is often guided by applying conceptual frameworks like the "mitigation hierarchy" or "mitigation sequence".[2] This generally includes the steps avoid, reduce, restore, and offset.[3] In some countries, environmental mitigation measures, including biodiversity offsetting, may be required by law.[4]
In practice, environmental mitigation measures might be implemented by establishing new habitat, restoring degraded habitat, and preserving or enhancing existing habitats to offset impacts that cannot be avoided or reduced.[5] It is also often applied with certain objectives for biodiversity levels or specific ecosystems in mind, such as "no net loss" or "net gain".[6]
