The PalmGHG Calculator was developed by the Greenhouse Gas Working Group 2 of the RSPO to allow palm oil producers to estimate and monitor their net greenhouse gas emissions. The Calculator also enables palm oil producers to identify crucial areas in their production chain and thereby guiding emission reduction opportunities.
The PalmGHG Calculator was first made publicly available on the RSPO website at the end of 2012. In August 2014, an updated PalmGHG calculator Version 2.0.1 was released following by an upgraded Version 2.1.1, to be used throughout the implementation period towards the mandatory public reporting of GHG emissions (until 31st December 2016).
During the implementation period towards mandatory public reporting PalmGHG Version 2.1.1 was further reviewed and modified by the RSPO’s Emission Reduction Working Group (ERWG) based on feedback from companies. In November 2016, PalmGHG Version 3.0.1 was released and Table below summarises the major changes with Version 2.1.1.
Calculation is based on 3-year average
Only 1 year of data is required
Biomass to carbon conversion factor
Crop sequestration model
Dynamic Growth Model based on OPCABSIM & OPRODSIM
Static Growth Model based on OPCABSIM & OPRODSIM
LUC emission from other land use (i.e. road, ditches, mill)
Not included. LUC emission calculated based on planted area
Included. Default assumption provided but user can key in own value
Fertiliser: sea transport distance
No RSPO default provided
RSPO default provided
N2O emissions from compound fertilisers
Not yet included.
Only N2O emissions for straight fertilisers included
No RSPO default provided
RSPO default value provided
Measurement of COD removed
COD removed is to be calculated by user
Palm Oil Mill Effluent (POME) diverted to compost
Assumes that POME is not diverted for composting prior to anaerobic digestion
Users can specify volume of POME is diverted to composting
Public Reporting Starting 1st January 2017:
Starting 1st January 2017, the RSPO PalmGHG Calculator or an RSPO endorsed equivalent shall be used to calculate GHG emissions from operations including land use change GHG emissions after November 2005. Public reporting of GHG emissions is mandatory through annual audit summary reports published on RSPO Website. Independent smallholders are encouraged to use PalmGHG Calculator; however, it is not mandatory.
Submission of PalmGHG reports to the RSPO Secretariat is highly recommended to enable continued review of the use of the tool, to facilitate analysis of data and to inform future revision of the PalmGHG calculator.
Please read the below description to choose and download the PalmGHG V3 installer that suits you best:
PalmGHG V3.0.1 (Existing User-LiteFile) (16MB) – This is strictly for users who have already installed PalmGHG V2 on their computers. This is because the necessary supporting software to run PalmGHG is already installed (via PalmGHG V2). Therefore, the full installer is not required.
PalmGHG V3.0.1 (New User-MainFile) (42MB) – New users who have not installed PalmGHG V2 before will need to download the Full version for installation. PalmGHG requires both .Net Framework 4 and Microsoft Access Database Engine in order to run.
