A Quote by Alex Steffen
Cities generate most of the global economy, and most of its energy use, resource demands and climate emissions. How we build cities over the next decades will largely determine whether we can deliver a bright green future.

Fifty percent of the world's population lives in cities. In a couple of decades, 70 percent of the world's population will be living in cities. Cities are where the problem is. Cities are where the solution is, where creativity exists to address the challenges and where they have most impact. This is why, in 2005, the C40 was founded, an organization of cities that address climate change. It started with 18 cities; now it's 91. Cities simply are the key to saving the planet.
All cities do face similar, significant trends in the future... most importantly global warming and climate change.
As each country looks to meet their emissions reduction, energy efficiency, or renewable energy goals, they will look to cities as places where transformational change can make the most difference.
That's not a utopian vision. It is a set of ideas that we think are important to discuss. Those ideas largely have to do with sustainability of cities. The ability of cities to, over time, remain in balance with the resource streams that are available to them, and they have to do with social justice and equity of the fundamental conditions of satisfactory citizenship.
Climate action in cities is the key that unlocks a low emissions and resilient future.
As industries migrate toward the Far East, the future of many Western cities will no longer lie in manufacturing products but ideas and patents. Young, mobile elites can choose where they want to live, and they can easily move, which means that cities are involved in a heated competition for the best people. Only the most attractive cities can benefit from this development.
CO2 is a minor player in the total system, and human CO2 emissions are insignificant compared to total natural greenhouse gas emissions. Therefore, lowering human CO2 emissions will have no measurable effect on climate, and continued CO2 emissions will have little or no effect on future temperature....While controlling CO2 emissions from burning fossil fuels may have some beneficial effects on air quality, it will have no measurable effect on climate, but great detrimental effects on the economy and our standard of living.
Many countries - as well as cities, states and provinces - are taking global warming seriously and are working to reduce emissions and shift to cleaner energy sources.
For carbon-neutral cities, there are things worth talking about in how our consumption patterns can change - sharing goods, etc. - but those are a fraction of the impacts of transportation and building energy use. If we need to choose priority actions, the most important things are to densify, provide transit, and green the buildings.
The opportunities of the twenty-first century make those of us who care about cities feel like kids in a candy store: How will cities survive and lead the way in the transformation required to combat global warming? Resilient Cities gives us a road map for this epic journey upon which we are embarking.
There's no getting around the fact that some cities face long odds, and governments and societies are going to be confronted with some hard decisions. Most importantly, cities have to recognize that in times of crisis they have to help themselves. Governments, no matter how well intentioned, can only do so much, especially when they themselves are so strapped for cash, as the U.S. is now. Government money will probably flow to cities and regions with good prospects for the future, so as not to risk money even further by pouring it into stalled economic models.
The economy of the future has been aligned with the climate agenda. Even the competitiveness of companies will depend on how resource efficient they are.
When we deal with cities we are dealing with life at its most complex and intense. Planners are guided by principles derived from the behaviour and appearance of suburbs, tuberculosis sanatoria, fairs and imaginary dream cities - from anything but cities themselves.
I think cities are the primordial forests of our time. We evolve faster as a species in cities. Cities are chaotic, liminal places where the many aspects of human potential, good and/or bad, are most readily magnified.
Cities are the origins of global warming, impact on the environment, health, pollution, disease, finance, economies, energy are all problems that are confronted by having cities. That's where they - all these problems come from.
To those of us who have been following the climate debate for decades, the next few years will be electrifying. There is a high probability we will witness the crackup of one of the most influential scientific paradigms of the 20th century, and the implications for policy and global politics could be staggering.
