Established world forests sink carbon equivalent to 33% of carbon world emissions from fossil fuel


Total world established forests sunk 2.4 PgC/yr from 1990-2007 (Yude Pan et al. 2011)

Mean world fossil fuel emissions 1990-1999: 6.4 PgC/yr Mean world fossil fuel emissions 2000-2009: 7.8 PgC/yr [AH math]: (6.4+7.8)/2 = 7.1 Mean world fossil fuel emissions from 1990-2009: 7.1 PgC/yr (C. Le Quéré et al. 2013)

[AH math]: 2.4/7.1 = 33% Established world forests sink carbon equivalent to 33% of carbon world emissions from fossil fuel

established world forests accounted for 3.5 billion ha in 1990 and 3.3 billion ha in 2007 (Yude Pan et al. 2011)
