Welcome to CORE

This website provides an up-to-date analysis and synthesis of the most influential offset programs and activities. It reflects on lessons learned, and aims to inform consumers as well as participants and designers of current and future offset programs.

The site is maintained by the Carbon Offset Research and Education (CORE) Initiative of the Stockholm Environment Institute. It is divided into three sections which are interlinked:

Policy Information	- provides in-depth analysis and information about offset design and policies.
Consumer Information	- provides information relevant to offset buyers and offers an introduction to the world of carbon offsetting.
Aviation Information	- provides an introduction to the issues related to GHG calculations from aviation for carbon offsetting.
