Living biomass holds about 550 gigatons of carbon, [1] most of which is made of terrestrial plants (wood), while some 1,200 gigatons of carbon are stored in the terrestrial biosphere as dead biomass. [2] Carbon is cycled through the terrestrial biosphere with varying speeds, depending on what form it is stored in and under which circumstances. [3]
Fossil fuel phase-out is the gradual reduction of the use and production of fossil fuels to zero, to reduce air pollution, limit climate change, and strengthen energy independence. It is part of the ongoing renewable energy transition , but is being hindered by fossil fuel subsidies .
Globally, terrestrial and oceanic habitats produce a similar amount of new biomass each year (56.4 billion tonnes C terrestrial and 48.5 billion tonnes C oceanic). Net primary production is the rate at which new biomass is generated, mainly due to photosynthesis. Global primary production can be estimated from satellite observations.
The following table shows the vegetable oil yields of common energy crops associated with biodiesel production. Included is growing zone data, relevant to farmers and agricultural scientists. This is unrelated to ethanol production, which relies on starch, sugar and cellulose content instead of oil yields.

An overarching term is carbon pool, which is all the places where carbon on Earth can be, i.e. the atmosphere, oceans, soil, florae, fossil fuel reservoirs and so forth. A carbon sink is a type of carbon pool that has the capability to take up more carbon from the atmosphere than it releases.
Because algae lack the complex lignin associated with terrestrial plants, the carbon in algae is released into the atmosphere more rapidly than carbon captured on land. [135] [138] Algae have been proposed as a short-term storage pool of carbon that can be used as a feedstock for the production of various biogenic fuels. [139] Women working ...
The standard Hubbert curve.For applications, the x and y scales are replaced by time and production scales. U.S. Oil Production and Imports 1910 to 2012. In 1956, Hubbert proposed that fossil fuel production in a given region over time would follow a roughly bell-shaped curve without giving a precise formula; he later used the Hubbert curve, the derivative of the logistic curve, [6] [7] for ...
