Emissions reduction of 6 % / year and 100
GtC storage in the biosphere and soils are needed to get CO2 back to 350 ppm, the approximate requirement for restoring the planet's energy balance and stabilizing climate this century.
A cumulative industrial - era limit of ∼ 500 GtC fossil fuel emissions and 100
GtC storage in the biosphere and soil would keep climate close to the Holocene range to which humanity and other species are adapted.

A limit of approximately 500
GtC on cumulative fossil fuel emissions, accompanied by a net

Complete restoration of deforested areas is unrealistic, yet 100
GtC carbon drawdown is conceivable because: (1) the human - enhanced atmospheric CO2 level increases carbon uptake by some vegetation and soils, (2) improved agricultural practices can convert agriculture from a CO2 ource into a CO2 sink [174], (3) biomass - burning power plants with CO2 capture and
storage can contribute to CO2 drawdown.

storage solutions and innovative features such as touch - screen infotainment, automatic seat - belt presenters and a Bentley - designed Neck Warmer for comfortable roof - down motoring whatever the temperature.
I looked at the numbers based on IPCC tables for land types by area and carbon
storage and plant vs soil carbon, and I conclude maybe 60
