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

2 ECOBICI Individual Transport System
3 Minibus and Taxis Replacement Program
4 Metro Line 12
5 Sustainable Housing Program
6 Solar Energy Use Regulations

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

h i f i b l h lik l f h i i i d the aim of creating green belts that act like lungs for the city, retaining dust 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 NAT bli h d hi h t bli h th t h i l NADF‐013‐NAT‐2007 were published, which establish the technical specifications for the installation of green roof systems in the Federal District. Yautlica Environmental Education Center.

In 2007 and 2008 results for green roof construction on urban In 2007 and 2008 results for green roof construction on urban

buildings in Mexico City were 3,578.82 m2 and 6,200 m2 respectively.

In2009, by means of resolute measures to mitigate

environmental impact the following buildings have green roofs: environmental impact, the following buildings have green roofs:

Plaza Central with a green surface area of 3,000 m2 Preparatory School “General Lázaro Cárdenas del Río” with a Preparatory School General Lázaro Cárdenas del Río with a

green surface area of 183.50 m2

f 183.50 m2.
In 2010, there are 13 public buildings (hospitals and schools)

whose structural analysis enables them to participate in the program.

Their combined total green surface area comes to 13,012 m2.
