  1. Slaying the Carbon Dragon: Making sense of carbon footprinting Lunch Hour Talk September 08 2011, Intaka

  2. Carbon Calculated Founded 2008 Need for cost-effective solution Trained in GHG Protocol (WRI & WBCSD) - organisational - project - verification - CarbonKnown

  3. Myriad concepts Uplift factors CO2e Operational boundary Global warming potentials Scope 1, 2 &3 Organisational boundary Direct emissions Emissions factors Indirect emissions

  4. What is a GHG? Not just Carbon dioxide - 6 main GHGs, incl: CO2, SF6, CH4, N2O, HFCs, PFCs Purpose of a carbon footprint To capture as many DIRECT GHG emissions and INDIRECT GHG emissions as possible from an organisation/product. “You can’t manage what you can’t measure”

  5. Methodologies Greenhouse Gas Protocol ISO 14064 PAS 2050 (product) Feeds into: Carbon Disclosure Project (Q7-15) JSE SRI Global Reporting Initiative (EN16-20) Various climate registries Different methodologies All born out of GHG Protocol

  6. Direct emissions Emissions from equipment that an organisation owns or has control of. Indirect emissions Emissions that an organisation’s activities are responsible for, but for which they do not own the equipment. Direct & indirect emissions • Vehicle fleet • Air conditioning & refrigeration • Generators • Electricity • Air travel • Office paper • Commuting • Logisitics

  7. Emission scopes Purposefully confusing, but does prevent double-counting! Compulsory vs. voluntary

  8. Emission factor Turns activity into actual GHG emissions. So how do you do it? Multiply the volume of activity by an emission factor E.g. electricity Currently Eskom EF for electricity = 0.99 kgCO2 per kWh Vodacom SA 2011: 297 615 982kWh = 294 640tCO2e

  9. Emission factors: Constantly changing E.g. Electricity was 0.96kgCO2/kWh Footnotes on EFs An evolving science Global Warming Potentials (GWPs) “Potency of a GHG to CO2 in terms of it’s global warming potential” Methane (CH4) = 21 Freon (HCFC22) = 1 500 SF6 - 22 800

  10. Emission scopes Purposefully confusing, but does prevent double-counting! Compulsory vs. voluntary

  11. Getting the carbon message The South African reality - It’s the energy, Stupid!

  12. Cost of electricity Getting the carbon message The South African Reality 2010-11: 24.8% (ave. R0.4131/kWh) 2011-12: 25.1% (ave. R0.5168/kWh) 2012-13: 25.9% (ave. R0.6506/kWh) Total increase: 75.8% over 3 years Source: Electricity Monitor

  13. Getting the carbon message The South African Reality Cost of carbon Fossil fuel levy: 2c/kWh Carbon tax: R165/tonne? I kWh = 0.99kg C02 I kWh in 2013 = 65c + 16.4c = R0.81 National GHG reduction targets: 34% by 2020; 42% by 2025 agains B.A.U

  14. Target: Reduce emissions 12%/FTE; 2007-15 Getting the carbon message Achieved: 13% energy reduction/FTE; Carbon neutrality Interventions: Motion sensors, heat pumps, building retrofitting; offsetting Financial investment: R6,6 million (excl. offsetting) Financial savings: R36 million

  15. Target: Reduce absolute emissions 10% by 2009-12 Getting the carbon message Achieved: 29% energy efficiency at Medupi expansion; 60% reduction in eco-friendly housing; 17% savings from co-generation at Namakwa Sands Interventions: wind & solar; co-generation; carbon credit trading Financial savings: R21 million per year

  16. Target: Reduce emissions 30%/m2 2006-12 Getting the carbon message Achieved: 10% reduction in relative energy use from 2004; 35% reduction in refrigerant energy in select stores; Midrand distribution centre savings 9 370km per week. Interventions: Energy efficiencies; reduced product miles Financial savings: R10 million
