The ASEAN region faces several challenges in protecting the environment and ensuring the sustainability of its natural resources. The ASEAN State of the Environment Reports highlight key characteristics and developments concerning the condition of the environment. These include what ASEAN is doing to address the challenges at the national and regional level. An ASEAN Community is envisioned by the year 2020. Therefore, this report has paid special attention to our community building efforts toward an environmentally sustainable ASEAN Community. The Vientiane Action Programme 2004–2010, the current roadmap, demonstrates our commitment through concrete measures and milestones to achieve this goal. The environmental programmes and measures in the VAP are situated within the context of sustainable development to ensure full integration and mutually supportive development of the various inter-related sectors.
