The Nuts and Bolts of Baseline Setting : Why, What and How?

This document provides an overview of baseline setting for greenhouse gas (GHG) crediting mechanisms. The main purpose of this note is to examine key issues for baseline setting in the context of scaled-up crediting mechanisms, and the discussion takes into account concepts developed and experience gained under these mechanisms. In addition, most of the concepts and examples presented here are relevant to setting baselines in the energy and industry sectors.
