The Environmental Valuation Reference Inventory is a searchable storehouse of empirical studies on the economic value of environmental assets and human health effects. 

Over the past decades, the volume of published literature on the economic value of ecological goods and services has significantly expanded, and environmental considerations are being increasingly integrated into business and policy decision-making. One arising challenge for researchers, economists, and analysts is to quickly and efficiently find relevant references of valuation studies amidst the growing volume of available information. The Environmental Valuation Reference Inventory (EVRI) is an online, searchable compendium containing classified summaries for over 4,000 valuation studies. These summaries provide detailed information about the study location, the specific environmental assets being valued, the methodological approaches and the estimated monetary values along with proper contextualization. EVRI’s primary objective is to facilitate literature review and the application of value transfer techniques.
