Impact Assessment (IA) is an environment and sustainability discipline. Its purpose is to ensure that environmental and social issues are identified and can be factored into the decision-making processes. For example, the development and adoption of public policies and plans and the consenting of public and private development projects.

At its best, IA helps shape policies, plans, design and consenting such that social value to communities and economic value to investors are both met, without eroding biodiversity and natural capital and without pushing beyond environmental limits.

IA practitioners are highly skilled. As regulated processes, the procedural complexities are potentially demanding, requiring leadership from competent environment and sustainability professionals. Tools applied across the IA discipline include: EIA, ESIA, SEA, SA, RIA, HRA.

Current priorities for IA include ensuring that the process is proportionate, effective and adaptable to future opportunities and challenges. We will be working hard to ensure that IEMA is the home of the Impact Assessment professional by bringing you events, webinars, guidance, articles and more.
