Right now, as you read this, wherever you are, we are in uncharted territory. Our global population of 7.1 billion is headed for more than 9 billion by 2050. With our growing numbers and aspirations for shared prosperity comes a growing demand for energy to power homes, businesses, industry and transport. Our continuing reliance on fossil fuels is generating pollution and a dangerously high amount of greenhouse gas emissions – this past summer, the concentration of CO2 in the atmosphere passed levels not seen in 3 million years.
If you were in Beijing last week, you felt the impact in your lungs: Just 16 days into the new year, the city woke up to its first “airpocalypse” of 2014, the latest in a series of dangerously high smog days. Beijing’s mayor announced plans the same day to cut coal use by 2.6 million tons and ban heavily polluting vehicles.
That was an important local step, and we are seeing forward-thinking cities and national governments make similar moves as they develop the architecture for a cleaner, low-carbon future.
