Environment Statistics

In September 2022 UNSD launched its 10th round of data collection for environment statistics through the UNSD/UNEP Questionnaire 2022 on Environment Statistics. This website contains the most recent country replies to the water and waste sections of the UNSD/UNEP Questionnaire, be they the most recent collection cycle, or from one of the nine previous collection cycles. Each country's file has the corresponding collection cycle denoted in parentheses.

As part of its data validation process, UNSD may send questions to countries for clarification. When countries reply with corrections, the original country file may be modified. If a country does not reply to UNSD's questions, UNSD may omit numerical data or footnotes that appear unvalidated or lack clarity. Per demands from key institutional stakeholders and other users in general, this webpage is periodically updated as new Country Files are finalised by UNSD.

The main aim of this webpage is to share country data and to avoid multiple collections of the same data. International organizations that intend to collect these or similar data from countries are requested to coordinate with UNSD before launching their data collection activity.
