Abstract: | Better software engineering such as archiving releases with version control, writing portable code, publishing documentation
and results closely tied to the code improves integrated assessment models' transparency and control. A case study of four
climate change policy analysis models found that source code and data was generally available, but for larger models licenses
were more restrictive with respect to modification and redistribution. It is suggested that Free software licenses such as
the GNU GPL would improve transparency and control. Moreover, opening the source allows opening the development process, a
potentially important tool to improve collaboration, data sharing and models integration.
