A meta-analysis of the greenhouse gas abatement of bioenergy factoring in land use changes

Abstract Non-food biomass production is developing rapidly to fuel the bioenergy sector and substitute dwindling fossil resources, which is likely to impact land-use patterns worldwide. Recent publications attempting to factor this effect into the climate mitigation potential of bioenergy chains hav...
