Two tropical forest conservation efforts have gained momentum in recent years: zero deforestation commitments from the private sector and the policy framework Reducing Emissions from Deforestation and forest Degradation (REDD+). Both efforts are necessary, but not sufficient in themselves to eliminate global deforestation.
In a recently published paper in the Journal of Sustainable Forestry, we find that linking REDD+ and zero deforestation commitments offers a more efficient and effective solution to stop deforestation, which we call Zero Deforestation Zones (ZDZ).
The current state of private initiatives and REDD+
Deforestation, which is responsible for 15% of global greenhouse gases, is primarily caused by conversion for the production of four commodities in Brazil and Indonesia: beef, soy, palm, and timber products. To address this urgent problem, companies that control more than 90% of soy purchases in the Amazon, around half of cattle slaughter in the Brazilian Amazon, and 96% of palm oil trade globally have committed to stop deforestation.
While these company commitments are promising, many producers that clear forests can still sell commodities to companies that don’t have deforestation commitments, or they can even sell indirectly to the companies that have committed to zero deforestation. In other words, under the current policies even if companies clean up their own supply chains, they could be just creating islands of green in a sea of deforestation. Read More
