If the assessment is favourable, and the proposed policy is enacted—after a suitable length of time for the policy to gain traction—it might be followed by an impact evaluation; ideally, assessed impacts before the fact and evaluated impacts after the fact are not wildly divergent. In some cases, impact becomes politicized due to a change ...
The Environmental Impact Assessment Law (EIA Law) requires that an environmental impact assessment be completed prior to project construction. However, if a developer completely ignores this requirement and builds a project without submitting an environmental impact statement, the only penalty is that the environmental protection bureau (EPB ...

Other authors make a distinction between "impact evaluation" and "impact assessment." "Impact evaluation" uses empirical techniques to estimate the effects of interventions and their statistical significance, whereas "impact assessment" includes a broader set of methods, including structural simulations and other approaches that cannot test for ...
Environmental impact design impacts can be broken down into three types: Direct impacts: caused by the project and building process, such as land consumption , erosion and loss of vegetation. Indirect impacts: side-effects of a project such as degradation of surface water quality from erosion of land cleared as a result of a project.
An economic impact analysis only covers specific types of economic activity. Some social impacts that affect a region's quality of life, such as safety and pollution, may be analyzed as part of a social impact assessment, but not an economic impact analysis, even if the economic value of those factors could be quantified.

The United States uses a cumulative impact assessment (CIA), also referred to as cumulative effects assessment (CEA), which is a process that identifies additive or interactive environmental effects occurring from human activities over time in order to then avoid cumulative environmental effects.

Social impact assessment (SIA) is a methodology to review the social effects of infrastructure projects and other development interventions. Although SIA is usually applied to planned interventions, the same techniques can be used to evaluate the social impact of unplanned events, for example, disasters, demographic change, and epidemics.
