"In fact, only in the case of essentially complete elimination of emissions can the atmospheric concentration of CO2 ultimately be stabilized at a constant level."

Innovating to
​ Zero Carbon

It is scientifically impossible for today's catastrophic atmospheric carbon dioxide concentration (400 ppm) to fall ​unless our industrial carbon emissions stop, and we must get below 350 ppm to prevent planetary catastrophe. 
"We should be talking about emissions targets, and the right emission target is zero."
(Ken Caldeira climate expert Stanford​)
"I asked the top scientists on this several times: Do we really have to get down to near zero? Can't we just cut it in half or a quarter? And the answer is that until we get near to zero, the temperature will continue to rise." (Bill Gates)

​CO2 is the top cause of global warming and the cause of ​ocean acidification.

​Black carbon (soot) is second only to CO2 ​in global warming contribution,
​so zero carbon now appropriately means zero CO2 and zero black carbon.

'These [mitigation] pathways would require substantial emissions reductions over the next few decades and near zero emissions of carbon dioxide and other long-lived greenhouse gases by the end of the century'. (IPCC 2014 AR5 Headline Statements)
'Without mitigation policies, fossil fuel and industrial emissions could reach 55-70 GtCO2 by 2050 and around 90 GtCO2 by 2100. This is in stark contrast with a low carbon future, where the energy system needs to be virtually zero carbon by 2100' (PwC Briefing: IPCC Fifth Assessment Report (AR5) Working Group III – Mitigation of Climate Change April 2014)
