Zero net carbon

"Zero net carbon" or "low carbon" is a way of talking about the effect of human-caused GHG emissions on the atmospheric carbon dioxide level. If an activity is zero-net-carbon, it does not increase the level of carbon dioxide in the atmosphere. It is clear that, in order to reverse the trend of increasing GHG emissions due to new demand for energy, new development must be zero net carbon. Here are some ways that this can be accomplished:
