� Mexico City Action Program y g � Mexico City was the first city in Latin America to implement a Climate Action Program (DF has an area of 1400 Km2). � This program has enabled the reduction of 4 % of Mexico City’s greenhouse gas emission (1,397,942 metric tons of carbon dioxide). � The 2008–2010 Mexico City Climate Action includes: � 1 Transport Corridors / Zero Emissions Transport Corridor p p � 2 ECOBICI Individual Transport System � 3 Minibus and Taxis Replacement Program � 4 Metro Line 12 � 5 Sustainable Housing Program � 6 Solar Energy Use Regulations � 7 Mexico City Goverment Enviromental Management System � 8 Green Roofs Program 8 G R f P � 9 Recovery of the Rivers Magdalena and Eslava � 10 Restoration of Ecosystems and Compensation for Maintaining Environmental Services
The Green Roof Program’s objectives are: � To encourage and promote the construction and use of urban green roof systems systems. � To create the necessary conditions for the use of green roof systems, with the aim of creating green belts that act like lungs for the city, retaining dust h i f i b l h lik l f h i i i d and suspended particles in the atmosphere, filtering the air, regulating the humidity of the area and creating microclimates. � To promote and manage the creation of regulations, quality requirements, economic and tax incentives and projects for the use of green roof systems. p j g y � To create environmental awareness. It is expected that, with the implementation of the Program 10 000 square meters (m²) of green roofs implementation of the Program, 10,000 square meters (m ) of green roofs will be established per year in the 2010–2012 period.
� In December 2008 the Environmental Regulations for the Federal District NADF NADF ‐ 013 ‐ NAT ‐ 2007 were published, which establish the technical NAT bli h d hi h t bli h th t h i l specifications for the installation of green roof systems in the Federal District.

Some of the buildings with green roofs include: � The Natural History Museum, � Technical Secondary School No. 14 � T h i l S d S h l N � “Cinco de Mayo”, CENDI located on the street Delicias, � Insurgentes metro station building, Coyoacán � Preparatory School “Ricardo Flores Magón” � Preparatory School Ricardo Flores Magón , � Dr. Belisario Domínguez Specialities Hospital, � Iztacalco Preparatory School “Felipe Carrillo puerto”, � Yautlica Environmental Education Center.
