Does anyone know how many m2 or acres of jungle/forests are needed to offset the carbon footprint of the average American family?

Carbon bound in vegetation eventually ends up back in the atmosphere due to rotting or burning. Carbon footprint = carbon dug out the ground – carbon permanently stored back underground. As long as the latter number is roughly zero, there is no real offsetting.

Assume a family of 3, where each person burns 20 metric tons of CO2 per year. For afforestation, National Academies report on negative emissions estimates 0.7-6.4 (Mg/(ha y) C) or 44/12 times that for CO2, so call it 60 metric tons / (3 (Mg/(ha y) C) * 44/12) = 14 acres.
