Just to expand on Brian's information.
Oracle acquired the IP for GHG Accounting Software from Ndevr in 2011. We developed modules for E-biz and JDE.
Since the acquisition Oracle released modules for JD Edwards 9.0, as well as a module for E-Business Suite R12.
There was no code remediation required, and it has also been one of fastest rollout's of any [Oracle] acquired product, ever. (<4 months.)
The modules enable company's to capture and transform environmental data directly within their ERP systems. All that is required from the finance team is the processing of a single extra field of data at the time invoices are processed.
Ndevr continue to provide implementation services for both versions of the product as it requires a level of environmental legislation expertise not typically found within an IT consulting company.
If you are interested to learn more, or your sustainability experts want to check us out please don't hesitate to get in touch. We have successfully sold and implemented the software in many of Australia's largest and most complex organisations. (Complex from a size and structure point of view, as well as complex operations and high number of emissions sources.) We have several references with which to back this up.
