Sri Lankan Environmental Impact Assessment (EIA) reports show major inconsistencies in how they assess and communicate social impacts, according to a new study by Centre for a Smart Future (CSF). 

As Sri Lanka seeks to accelerate investment and infrastructure delivery amid heightened climate and environmental risks, EIAs are expected to function as a core tool to safeguard communities and ecosystems. 

However, CSF’s analysis suggests that the social dimension of EIAs is not provided sufficient attention, despite being a key requirement specified in national guidelines and Terms of Reference (TOR), undermining the use of EIAs for decision-making, accountability, and public confidence.

The report titled ‘Assessing the Assessments: An Analysis of Social Impacts Reported in Environmental Impact Assessments in Sri Lanka’ presents the first systematic review of its kind in the country, assessing 250 EIA reports published between 1991 and 2025 against national EIA guidelines and project-specific TORs to examine how social impact reporting has performed over time. 

Findings point to systemic issues, including frequent gaps in reporting methods and data sources, inconsistent quality expectations in TORs, and presentation and language styles that are often inaccessible to the public.

“EIAs are meant to anticipate and minimise harm to communities, especially those already exposed to environmental and economic vulnerability,” author of the report and CSF Research Associate Senith Abeyanayake stated. “But if social impacts are described inconsistently, supported by unclear evidence, and communicated in ways that the public cannot reasonably understand, EIAs cannot perform their intended role in development planning and governance.”

The report argues that improving social impact reporting is essential not only for affected communities but also for Sri Lanka’s broader development credibility. Better EIAs can strengthen investor confidence, reduce conflict and litigation risk, and help ensure development is more resilient in the face of climate-related hazards.

CSF is an interdisciplinary think tank working on research and advocacy to strengthen inclusive and sustainable public policies in Sri Lanka. The think tank emphasised that these recommendations were intended to support regulators, consultants, development partners, and civil society, and to open a constructive conversation on how EIAs could better serve Sri Lanka’s long-term development goals.
