A methodology to estimate national REDD plus reference levels using the Zero-Sum-Gains DEA approach

Abstract

REDD+ reference levels directly impact the benefits which a country may receive. However, the existing "Compensation Reduction" (CR) and "Compensated Successful Efforts" (CSE) are only considered from a unilateral perspective of outputs or inputs. The combination of these two approaches is considered to estimate the REDD+ reference levels through the Zero-Sum-Gains Data Envelopment Analysis in this paper. The agricultural labor force and agricultural land area are used as input variables, and the gross agricultural production and carbon emissions from deforestation are considered as output variables. The REDD+ reference levels of 89 countries are calculated and classified through the Zero-Su..
