While national governments have the main responsibility and authority to collect data and report on the state of the environment, they often lack adequate expertise to carry out these tasks. Moreover, there is often little cooperation and communication within and among national authorities working on environmental statistics. The target countries have requested support to improve environmental monitoring and assessment for progress towards multilateral environmental agreements and the 2030 Agenda, highlighting the need to enhance the comparability of environmental statistics for this purpose in the region. Through a Shared Environmental Information System (SEIS), this project aims to improve national capacities to produce, track and share environmental information and data. This project will also help target countries to identify best practices, measures and procedures to prepare a reporting mechanism, with a focus on the crosscutting nature of SEIS.
