The IEMA 'Perspectives' series provide detailed guidance on what constitutes a good practice approach to Environmental Assessment. The first in the series, Guidelines for Landscape and Visual Impact Assessment, was published in 2002, this has been followed by Guidelines on Participation in Environmental Decision Making and Guidelines for Environmental Impact Assessment.

Guidelines for Landscape & Visual Impact Assessment was published in partnership with the Landscape Institute. It provides assistance in predicting and judging the significance of the effects that new development may have upon landscape character and visual amenity.

Guidelines on Participation in Environmental Decision-making was the second Perspectives publication in 2002, and its purpose is to improve participation by demonstrating its importance, offering advice on how to achieve effective participation, providing practical examples of what has been achieved, and by providing inspiration and the information to 'do-it-yourself'.

Guidelines for Environmental Impact Assessment were published in 2004. They outline what forms good practice for each of the components of the EIA process. The publication is primarily aimed at EIA's undertaken within the Town and Country Planning System, but those involved in EIA within other Regulatory Contexts will also benefit from the guidance.
