GHG emissions the eThekwini experience
2
GHG Emission Inventory
3
GHG reporting in DurbanTwo previous inventories • 2002 Full GHG emission
inventory – data collected for Municipal contribution and estimated for Community or City-wide contribution
• 2004 The data collection was repeated and a summary published– Emissions from the greater
Durban community (estimates only)
– Data used to inform EMD Energy Efficiency project
4
eThekwini’s Approach: HEAT
• Online GHG emission calculator of ICLEI• EMD existing relationship with ICLEI Local
Governments for Sustainability• Improvement on Torrie Smith methodology • http://heat.iclei.org• A database that EMD could review and maintain
themselves
5
What is HEAT?
• Online software to support local greenhouse gas and air pollution emission reduction planning
• Build an emissions inventory based on local energy use, transportation demand, and waste practices
• Help a user/city build a simple emissions forecast • Set a target/goal for reducing emissions (e.g.,
reduce GHG emissions by 10%) • Provide a database for storage of emission data• Calculations using emission factors• Quantify emission reduction activities and their
co-benefits
6
Government inventory categories
Government Structure:•Buildings•Vehicle fleet •Employee commute•Streetlights•Water/sewage•Waste•Other
7
Community inventory categories
Community Structure:• Residential• Commercial• Industrial• Transportation• Waste• Other
8
GHG data collection• Contacted local Municipal departments• Contacted EMD staff collecting the same data for
SOER and State of Energy Department• Worked with Enviros, State of Energy Report
• Major data contributor, South Africa Petroleum Industries Association
• Sugar Milling Research Institute
• eThekwini Electricity

Observations
• Future reports should concentrate on addressing gaps in the data
• Various shortcomings in the software were identified – addressed ahead of future projects
• Verification of data at point of origin
