What is a Carbon Footprint?
What is a tonne of Carbon Dioxide?
• A tonne of Carbon dioxide written tCO2 is the international reporting standard for CO2 in metric tonnes.
• There are 2,204 pounds in each metric tonne of CO2. • 1 tCO2 is equal to the weight of a Volkswagen Beetle.
What is a tonne of Carbon Dioxide?
• 1 ton of CO2 easily fills up a 19,000 cubic feet / 556 cubic meters container.
Magic Carbon Output in Elephants
• An average adult Asian elephant is the equivalent to 5tCO2 in weight.
Magic Carbon Output in Average American Homes
• The Average American home produce 12tCO2 per year.
Magic Carbon Output in Terms of the Earth.
• The circumference of the Earth is 24,000 miles. For a Ford F-150 averaging 20 mpg to drive around the Earth, it would take 1,200 gallons of fuel.
• This trip would produce 10tCO2.

How to Assess Footprint

Purpose of Inventory
Internal planning for carbon neutrality
Outreach vehicle - stakeholder dialogue platform
Educational tool, Compliance tool
Purpose of Footprint
Planning a GHG Inventory
Questions that need to be considered include:
• What business unites/facilities will be included in the inventory (organizational boundary)?
• What GHG sources and activities will be included (operational boundary)?
• What base year will selected?
Planning a GHG Inventory
Inventory Work Has Several Stages
• secure management support• establish a team & prepare budget
• define inventory boundary• determine sources of emissions• select base year• design efficient data management system• obtain appropriate data, ensure data quality
• apply calculation tools• guard against calculation errors
• identify emission reduction opportunities• decide on target type & level
• implement emission reduction activities
• publicly report complete inventory information
