By fundamentally changing how we design the places and systems that enable our daily lives, we can slash emissions way beyond the immediate carbon savings - because our own personal emissions are just the tip of a vast iceberg of energy and resources consumed far from our view.
Carbon zero simply means that the emissions you are releasing either are zero or balance out to zero.
We don't need a War on Carbon. We need a new prosperity that can be shared by all while still respecting a multitude of real ecological limits - not just atmospheric gas concentrations, but topsoil depth, water supplies, toxic chemical concentrations, and the health of ecosystems, including the diversity of life they depend upon.
We're becoming a planet of a thousand new major cities. The economy of the 21st century is a city-building economy. It's within our power to make it a carbon zero one, too; and to be blunt, civilization depends on our success.
One of the more fantastic possibilities is that man will be able to make biological carbon copies of himself.
The human foot has bones and muscles and can balance back and forth. If you step and you maybe make a little mistake, your foot can compensate. But if I step in the wrong spot, my foot isn't going to compensate because it's just one piece of carbon fiber.
If you look at the ecological circuitry of this planet, the ways in which materials like carbon or sulfur or phosphorous or nitrogen get cycled in ways that makes them available for our biology, the organisms that do the heavy lifting are bacteria.
The problem with cap-and-trade and programs such as carbon capture and storage is that they all assume that business as usual can continue. The financial meltdown and peak oil has pretty much demonstrated that business as usual's not going to work.
America is a global leader on clean air progress and carbon dioxide reductions, and we are the envy of the world when it comes to clean water.
It's a really big deal to do a spacewalk. It's much riskier than staying indoors. It's complex. It uses up a lot of the precious resources onboard. It uses up oxygen. It uses up carbon dioxide scrubbers.
