This is the first Malaysian common carbon metric study based on UNEP Sustainable Building & Climate Initiative (SBCI) CCM Protocol. This study was made by Steve Lojuntin and Dr Faridah Shafii under the Putrajaya Green Township Programme. Later the output used as input to the development of the Green Performance Assessment System (GreenPASS) by CIDB, a government low carbon green building tool based on carbon assessment.
