The Malaysia government are working for new Malaysia Green Building Ratings System. The system will utilize the carbon emission as universal unit for the Green Criteria, however not all criteria can be convert to CO2 emission.
The situation in Malaysia is currently like the Halal Certification, the are more and more Green Rating System developed locally, not only GBI. Even Penang Authorities also come with their own Green Rating System. This might be because there are so many complaint on GBI. The authorities not really happy, then JKR have developed their own pHJKR, the developer also not really happy, REHDA developed GreenRE (RE stand for real estate, Penang Authority develop Penang Green Office, CIDB developed GreenPASS. Now is time to have the national rating system.
