- JICA's approach to marking Rio markers involves a process of project identification, policy dialogue, and project formation between JICA and partner countries to determine if a project's objectives and expected results primarily address climate change or biodiversity (principal marker) or contribute in a non-primary way (significant marker). - JICA developed a Climate Finance Impact Tool to provide methodologies for measuring and reporting mitigation and adaptation results and to mainstream adaptation into projects. - Rio marking should be an integral part of project appraisal to help mainstream climate and biodiversity objectives, and the process facilitates policy dialogue between partners on development priorities.
