Transcript of Sustainable Cities
Mauro Villaseñor & Myrna Arias
What is a Sustainable City?
Is a city designed with consideration of environmental impact...
...inhabited by people dedicated to minimization of pollution and waste of energy, food and water.
"A sustainable city should meet the needs of the present as well as that of the future generation."

Promotion of sport, arts and leisure
Pros and Cons of Sustainable Cities
Have a sustainable balance in Social, Economic and Environmental terms.
Promote high quality lifestyle (Medical, Educational and Social ways).
Promote the use of Sustainable products, gadgets or procedures.
Promote a clean image.
Between many others...
Are difficult to start.
Can only create doubts and sink with them.
People can hardly follow the rules and changes.
The technology cannot be efficient.
The maintenance of the technological devices can be expensive.
The technological devices can be of low quality or very fragile.
Examples of Sustainable Cities
The top 5 most successful
Hydroelectricity powers 90% of its energy supply.
Uses solar, wind and wave power.
Has bike lanes.
Has the lowest per-capita carbon emissions of any major city on the continent.
Completely sustainable by 2020.
Needs more electric powered cars.
Needs to lower CO2 emissions by cars.
Needs to get rid off sewage wastes to the sea.
San Francisco, CA; USA.
Good air treatment.
Excellent waste management.
Recycles 77% of its waste.
Has over 160 public charging stations (for electric cars) and plans to install an additional 2,750.
Has more than 497 LEED-certified green building projects.
Completely sustainable by 2018.
Needs to use more alternative energies.
Needs more green areas.
Needs more population control.
Has more than two-thirds of its municipality covered in protected forest, waterways, and agriculture land.
Uses bio-methane from waste to power mass transit and heating.
Has an “eco-certification” program that involves all 43,000 employees of the city.
By 2030, Oslo aims to cut carbon emissions by 50%.
Has bike lanes.
Has 400 charging stations installed downtown.
The city’s heating system is currently powered by 80% renewable energy, mainly from biomass from residual waste. This relationship annually saves the carbon emissions equivalent to 60,000 vehicles.
Within the next decade, Oslo plans on expanding the system to reach 100% renewable sources for heating.
Completely sustainable by 2025.
Only non-polluters were invited to resign within its limits.
Where there was once only one square meter of green space per person, now there is more than 52.
Over 1.5 million trees have been planted along city streets and a network of 28 parks and forests developed.
Some 2.3 million people a day use Curitiba’s inexpensive and fast transit service.
90% of residents recycle 2/3 of their garbage daily.
The city has even come up with an innovative program that allows people to exchange trash for transit tokens or fresh products.
Has an excellent recycle management
Uses alternative energies.
Completely sustainable by 2016.
More than a third of the city’s 1.2 million people regularly cycle to work via more than 217 miles of dedicated bike lanes.
Officials hope to get 50% of the population on two wheels by 2015 by closing down some major roads to cars and developing an additional 43 miles of bike lanes.
Has the largest wind turbine industry in the world, supplying roughly 19% of the country’s power needs.
A new offshore wind farm planned for 2013 (featuring 111 turbines) will supply an additional four percent.
As part of their goal to be the world’s first carbon neutral capital by 2025.
City officials have instituted a mandatory green roof policy.
“Pocket parks” (half the size of a soccer field) are being installed around Copenhagen so that by 2015, 90 percent of all residents will be able to walk to a green space in less than 15 minutes.
The three R´s are used by most of the 90% of the population.
There are no many public transport, because they use bikes instead.
Almost 70% of the population is Semi-vegetarian.
Use of alternative energies.
Completely sustainable by 2015.
What about Mexico
Regarding to the capital(which is the first city to implement sustainable topics), as in any mega-city, Mexico City faces a variety of environmental challenges. Urban growth, combined with a rising middle class population, today requires innovative thinking and policies in urban planning, transportation, air pollution, water scarcity and solid waste, among others. Mexico City has adopted a 15-year Green Plan to address these environmental challenges simultaneously.
Mexico City is investing more than $1.5 billion a year (51% of all tax revenue) on improving public transportation systems, including expansion of its Metro subway system (already one of the world’s largest).
Mexico City is upgrading the current bus system with a program to replace aging private bus and taxi systems with fuel-efficient, less polluting models.
Mexico City implemented the "Ecobici" bicycle sharing system where residents can rent bikes from kiosks set up around the city.
Mexico City’s government is educating business and consumers on water conservation efforts, investing in new water treatment facilities and improving water infrastructure to reduce leakage.
Mexico has expanded the BRT system, which includes 40 kilometers of dedicated bus lanes around the capital and is comprised of 80 bus stations and 200 technologically modern, low-pollution buses.
The buses currently serve an estimated 500,000 travelers daily.
If Mexico wants to be sustainable, it has to focus on:
Banking & Financial Services
Information Technologies & Telecommunications
Science & Technology
Mexico City CAN be completely sustainable by:
Thanks for watching!
If we want to change our cities, we have to start by ourselves. Here is a video for a campaign in Vancouver showing how they are made of. Now see were they are, they are sustainable. So, what are you waiting for being like them?
