The carbon issue

The carbon concept refers to two realities: 80% of the energy consumed in the world comes from fossil fuels, and CO2 accounts for the great majority of our greenhouse gas emissions. We therefore face a double constraint: on the upstream side, the constraint is our stock of energy, and on the downstream side, it is the result of the combustion process used to release that energy that is the root cause of climate change. 

Our limited stock of energy will inevitably confront us with a peak of availability, followed by a decline in fossil fuel production, but this geological constraint should not be seen as the only compelling reason for action. The climate-change challenge makes it essential that we reach peak production at an earlier point than that imposed solely by geology, especially in the case of coal. This risks imposing a very significant and unprecedented impact on the primary factor of production that drives our economies.
