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)
