UNEP-RRCAP has produced the Environmental Indicators report for each sub-region of Asia and Pacific. We have painstakingly researched and collected data for a list of key environmental indicators. These indicators, which are replicated across each subregion, were chosen after serious deliberation by our inhouse experts, to best reflect the environmental concerns in and across the sub-regions. The indicators can be subdivided in to the following categories: 1. Social 2. Economy 3. Environment. The category environment is further sub-divided into 1.Land 2.Water 3.Air 4.Biodiversity. Thus, the above categories provide a comprehensive view of the sub-regional progress on environment and sustainability.
