There are several benefits for common way of working with LCA. One is to get comparable results. Other benefits are to help visualize environmental impact through all processes from planning to designing and construction further to operation and maintenance and follow-up. Possible applications of the LCA-tools are: - Environmental budget to be used by the NRA internally - Tender procedures (requirement or award criterion) - Accounting for environment after/during construction This report describes the most common tools used by the transport administrations in Finland, Norway and Sweden. The objective is to find similarities within the tools to find a common way of working with LCA in infrastructure projects and to learn from each other.
