A green input-output model and social accounting matrix: Contributions to the Integrated Green Economy Modelling (IGEM) tool

Event: Technical Workshop on Designing an Integrated Green Economy Modelling (IGEM) Tool for Informing Green Economy Policy Making Processes
Date: 22 April 2016, UNEP, Geneva
Presentation

Under the Partnership for Action on a Green Economy (PAGE), UNEP collaborated with the modelling experts (including Xin Zhou from the Institute for Global Environmental Strategies, Roy Boyd from Ohio University, Maria Eugenia Ibarrarán from Universidad Iberoamericana Puebla and Steven Arquitt from the Millennium Institute) to develop an Integrated Green Economy Modelling (IGEM) tool that aims to better respond to countries’ needs for assessing the impacts of green economy policies. The IGEM tool, built on UNEP’s past country experiences on modelling green economy policies, aims to provide an integrated quantitative assessment tool to inform the design and implementation of green economy policies.

The IGEM tool presents a framework of integrating three different modelling techniques that have been widely used for green economy policy assessment, namely the system dynamics (SD) model, the computable general equilibrium (CGE) model and the input-output and social accounting matrix (IO-SAM) models.
