ABSTRACT

Mitigation of human‐induced changes to the climate of the Earth is among the most pressing environmental challenges of the next decades. Reducing emissions of greenhouse gases and returning some of the carbon (C) back to Earth are both essential tools if countries are to become carbon‐neutral with regard to the greenhouse effects. Terrestrial carbon sequestration involves capture of atmospheric C through photosynthesis and subsequent storage in soils, wetlands, and biota. Being carbon‐neutral refers to reducing national greenhouse gas emissions as far as possible and offsetting the remaining emissions by reduction elsewhere.
