Life cycle assessment (LCA) is a structured, comprehensive method of quantifying material and energy flows and their associated environmental impacts caused throughout the life cycle of a good and/or service. The Joint Research Centre and the ISO 14040-14044 standards provide a framework for LCA assessments. However, this framework is general and not tailored to energy pathways and more specifically to geothermal systems. It leaves the user with a large range of choices resulting in a large variability in the LCA results that can affect their understanding by decision makers.
The GEOENVI project developed LCA Guidelines for Geothermal Installations, to offer methodological indications and assistance on how to perform LCAs of geothermal systems. These guidelines provide a common and accepted basis to evaluate the life cycle environmental impacts of geothermal energy systems to compare results for different geothermal settings and energy conversion technologies.
Implementation of LCA guidelines to six case studies: Environmental assessment of GEOENVI case studies following LCA guidelines
Recommendations from the combination of the national workshop’s feedback and the experience gathered during the application of the LCA guidelines: Harmonized Life Cycle Assessment Guidelines for geothermal installations
