The Greenhouse Development Rights Calculator
The Greenhouse Development Rights Calculator is a web-based application that calculates emissions allocations using the Greenhouse Development Rights framework. With the calculator, you can change key parameters, such as the development threshold or the relative weighting of Responsibility and Capacity, and then see how your changes affect allocations under the GDRs framework.
Disclaimer: We are continually developing the calculator, and sometimes make changes to the underlying dataset. Please check with us before using the outputs in a publication to ensure that you are using the most recent stable version.

Technical information about the calculations is available in a Working Paper.
The source code for the underlying calculator “engine” is open source, licensed under the very flexible Apache License. You can view the C source code online and download it from a subversion code repository. You can also view the source code documentation online.
If you want to use the output from the GDRs calculator in your own web application, you can access it via a web API. The API uses a REST approach, and all commands use standard GET and POST calls. For more information, please read the API documentation.
