Architects, engineers, developers and urban planners have a vision of cities as carbon sinks rather than sources. In addition to solar panels, rainwater collection, better design to limit heat gain and loss so buildings don’t use as much energy, the use of wood in constructing buildings can help store carbon in the built environment.
In addition, the manufacture and use of wood emits much less carbon dioxide than does concrete, steel or aluminum. There is a substitution benefit, the negawatt; less energy needs to be generated at the outset. As with electric vehicles, there is less energy used compared to the internal combustion engine.
