Presentation Transcript

  1. Carbon Footprint Presented by Bob Snowden

  2. Agenda • Introduction • What is a Carbon Footprint • How do we assess Carbon Footprint • Questions

  3. Carbon Footprint • What is a Carbon Footprint. • A way to quantify the amount of CO2 being produced.

  4. Carbon Footprint • Amount of GHGs (converted to CO2 ) which are emitted by a process • May include production (including raw materials), use and disposal of a product or provision of a service • Not only products are assigned a carbon footprint but also services or miles travelled have a carbon footprint. • What can we do with this “abstract“ number? • Compare or reduce.

  5. Carbon Footprint

  6. Carbon Footprint • Define the scope • Identify the sources of emmissions. • Materials used in construction, energy, chemicals, water, travel & transport. process • For each emission source indentify the Emission Factor. • How much CO2 is produce by each source typically Kg CO2e • Multiply up for the life of the process and add up the total. • Compare or reduce.

  7. Carbon Footprint Assessment Tools • Simplified Example:

  8. Carbon Footprint Assessment Tools • ComparingResults • The system has a footprint for the 5 years of 32098 Kg CO2 eq • For comparison it is useful to relate this to the output. i.e water production. • Our example produces 26280 M3 over the 5 years • Which gives a specific value of 1.22 Kg CO2 eq/M3

  9. Carbon Footprint Assessment Tools • Typical Results

  10. Overall reduction potential

  11. Reduction of carbon footprint How can the emissions be reduced? • Don‘t use the process • Reduce the energy it uses • Reduce /reuse waste water • Reduce materials used

  12. Questions
