Significant adverse impacts The identified impacts and their significance in each situation will typically differ dependent on the specifics of individual proposals. However, some general considerations on what might constitute significant adverse impacts will apply. In an overarching policy context, significant adverse impacts may include economic or social impacts on coastal communities, impacts that threaten the achievement of Irish Government targets, impacts that threaten the protection of designated sites, landscapes or historic assets, or impacts that threaten ecosystem resilience, or the achievement of Good Environmental Status (GES). In a key sectoral / activities policy context, significant adverse impacts may include impacts on the integrity and scope or economic viability of an existing or consented activity or potential future activity, including its capacity to provide wider social benefits.
