Coherence Between Climate and Land Use Policies of the European Union, Brazil, and Indonesia: A Primer to Analyze Potential GHG Leakage

Environmental Policy and Governance, EarlyView.
ABSTRACT Incoherence between national land use policies may weaken climate mitigation efforts by creating conditions under which agricultural and forestry production and GHG emissions are displaced across borders (leakage). Coherence depends on constellations and prioritization of national policy aims in land use (production) and climate (conservation).
