“SIGN SMART” is web basis software for supporting national and sub-national GHG inventory activity SIGN: Sistem Informasi GRK Nasional (National GHG Information System) SMART: Simple, Measurable, Accurate, Reliable, Transparent SIGN SMART was developed by SIGN center of the MoEF in 2014

1. A nested information system
on greenhouse gas emissions
(SIGN SMART)
Belinda Arunarwati Margono

2. Background
 Green House Gases inventory is required at
 Both national level and sub-national level (province,
district)
 Consist of five sectors:
Non land-based sectors: energy, transportation, and
waste
Land-based sectors: agriculture, and forestry
 Complex data, and bunch of worksheet to complete
 A need to simplify the worksheet
 By improving the efforts in gather and compile the data 
a system

3. SIGN-SMART
1. It was designed to support the concept of Transparency,
Accuracy, Consistency, Completeness and Compatibility (TACCC)
of GHG inventory
2. Provide advantages such as
 A user-friendly online system (with registered users)
 Data management system: the data that was entered and used
to estimate the GHG emission are stored in an integrated
database
 A quick GHG emission calculation (3-5 minute),
 That would be displayed as a user friendly graph, which was a
compilation of the all available worksheet from 2000-2014.
 Provide a near real time report
 In the same year of data input
 Before it was available as a system, the report would take
some time (it was in n-2)

4. SIGN SMART
 “SIGN SMART” is web basis software for supporting national and sub-
national GHG inventory activity
 SIGN: Sistem Informasi GRK Nasional (National GHG Information System)
 SMART: Simple, Measurable, Accurate, Reliable, Transparent
 SIGN SMART was developed by SIGN center of the MoEF in 2014
• Direct data input from data providers
(mainly private companies and local governments)
• Data archiving
• Automatic GHG estimation (EFs and
parameters are stored in the software)
• Output (graph, table, crf)
• Comparison among provinces
Main function of SIGN SMART

5. Approaches
for Development of GHG Inventory
 Two approaches:
• Top-down approach: using national aggregated data with
national ministries/institutions involvement
• Bottom-up approach: using sub-national aggregated data with
involvement of local government units.
 The challenge is to narrow the gap between the two estimates of
total GHG emissions
• Avoiding double counting (trans-boundary problem)
• Consistency in methodology (generating activity data)
• Capturing variability of local emission factors at national level
calculation

EXISTING
Data base/literature in printed form/hard
copy often not archived well.
For the next inventory year or
recalculation, its difficult to collect
previous data base/literature.
Difficulties in distributing top-down data
to province and city/district.
SIGN SMART
Data base/literature stored in the
system
For the next inventory year or
recalculation, the data matrix can be
called, and we just need to updating the
data.
Top-down data embedded in the
SMART-SIGN system
