Green engineering and sustainable design must consider the life cycle of carbon
as it forms various chemical compounds. When oxidized it forms CO 2 , and
when reduced it forms CH 4 . Both are important greenhouse gases. When in
excess and when in the wrong place (i.e., the troposphere), both are problematic.
Research and innovative thinking are needed on how best to limit releases to
the atmosphere and to find ways to remove the excesses. Again, this requires a
life-cycle perspective in design.
