Environmental Law in Arab States offers a comprehensive and authoritative account of the guiding principles and rules relating to environmental protection in the Arab region. Taking an international and comparative approach, the book introduces readers to the latest developments of environmental law across the Arab region through applicable legislation, green finance, and climate technologies The impact of these is assessed in each of the major areas of environmental regulation, air pollution, water pollution, biodiversity, conservation of nature and cultural heritage, infrastructure development, and Islamic ecology. Consideration is given to participatory and bottom-up legal strategies – focusing on transparency, accountability, gender justice, and other human rights safeguards – that are needed to achieve greater coherence and coordination in the implementation and enforcement of environmental regulation across the region. The book closes by providing legal assessments and reflections on how Arab countries can, through clear and comprehensive legislation, advance existing national strategies and visions on trade and investment, green growth, Islamic green finance, circular economy, blue economy, and low carbon future amongst others.
