Greenhouse Effect
Fact: Without GHGs, ave. surface temp of the earth would be 33°C
colder.
Fact: GHGs at levels unprecedented in last 650 000 years.
Fact: CO2 @ 280 ppm in pre-industrial times, now 383 ppm, and rising.
Fact:Methane (CH4) levels increased 150% since pre-industrial times.
N2O increased 18%.

Greenhouse Gases
Why is carbon important?
High-rising carbon
What is a carbon footprint?
Operational boundary
Organisational boundary
Indirect emissions
Direct emissions
Scope 1, 2 &3
Emissions factors
Global warming potentials
CO2e Uplift factors
Myriad concepts
Purpose of a carbon footprint
What is a Greenhouse Gas?
Not just Carbon dioxide
- 6 main GHGs, incl:CO2, SF6, CH4, N2O, HFCs, PFCs
To capture as many DIRECT GHG emissions and INDIRECT GHG emissions as possible from an organisation/product/individual.
Direct & indirect emissions
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.-Vehicle fleet
- Air conditioning & refrigeration
- Generators
- Electricity
- Air travel
- Office paper
- Commuting
- Logisitics
Organisational level
Emission scopes
Purposefully confusing, but does prevent double-counting!
Compulsory vs. voluntary
So how do you do it?
Emission factors & Global Warming PotentialsTurns activity into actual GHG emissions.
Multiply the volume of activity by an emission factor
E.g. South African electricity = 1.03kgCO2e/kWh
Petrol = 2.322kgCO2e/litre
Diesel = 2.672kgCO2e/litre
LNG = 1.4920kgCO2e/litre
Methane (CH4) = 21
Freon (HCFC22) = 1 500
SF6 - 22 800

Your personal footprint
Key elements
1. Main source of household energy - electricity, wood, gas, renewable?
2. Main heating source - electricity, coal, wood, natural gas?
3. Vehicles usage - litres of fuel OR Kms, fuel type and size of engine?
5. Air travel - journey and class?
4. Waste - type and weight?
6. Car rental - litres of fuel OR Kms, fuel type and size of engine?
7. Hotel accommodation - bednights?
Typical SA carbon footprints
Electricity: Medium South African houshold = 1 000kWh/month = 1 030kg CO2e/month
Commuting: 60km/day in a 1.6 litre petrol car = 12.96kg/day = 259.2kg/month
Commuting: 60km/day in a bus = 8.11kg/day = 162.2kg/month
Return flight Cnt/Jnb/Cnt Economy = 236kgCO2Return flight Cnt/Jnb/Cnt Business = 354kgCO2e
Comparative activities
Non-typical carbon footprint
- World’s largest individual carbon footprint in 2007
163t. (UK ave. 9.4t)- Numerous houses- 15 gas guzzlers
- 250 000 miles air travel

Hot tips to reduce a footprint
1. Efficient/renewable energy• Solar geysers • Geysers on timers & set at 55°C• Insulate geysers • Solar cooker/hot box (50% saving on electricity)• Heat pump (67% saving on electricity for A/C)• Kettle usage • Turn-off standby modes (electricity to 2 million homes pa in SA)• CFL bulbs instead of incandescent (5 x longer & 20% less electricity)
In the household
Hot tips to reduce a footprint
2. Meat-less • Animal protein is 11 times more fossil fuel intensive than plant protein• Livestock contribute 5.1% of total GHGs
3. Water• Shower instead of bath• Install water-saving shower head (reduce hot water consumption by 80%)
4. Laundry• Sun dry: not tumble dry (save 1.3kg CO2 per tumble dry).
In the household
Hot tips to reduce a footprint
1. Paper• Default to double-sided printing• Use recycled paper & purchase local (especially for marketing material) • Extend use of emails
In the office
3. Products & clients• Sell online•Incentivise a carbon-friendly supply chain
2. Meetings• Meet remotely
Hot tips to reduce a footprint
1. Getting to work• Fuel efficient or hybrid car• Car pooling (taxi)• Motor cycle• Bus• Train• Bicycle
On the road
Hot tips to reduce a footprint
2. Your vehicle• Diesel v petrol • Maintenance (check tyre pressure, air filter)
