The document outlines Mexico's policy approaches to meet these "green growth challenges" through innovative urban planning, housing, governance, and environmental management strategies. Key policies include establishing urban growth boundaries, green housing programs, a sustainable cities network, and metropolitan governance reforms like in Jalisco state.
