Week 3: Carbon Accounting And System Problem Analysis

Question 1

Why do we need to measure carbon emission?

Answer 1

• Set the budget
• Predictions
• Accountability (measure of success and monitoring progress)

Question 2

What does Accounting Method measure?

Answer 2

Amount/ mass of emissions associated with a good, service, or activity in kg CO2 eq.

Including set a system boundaries and perspective

Question 3

Basic formula for accounting method

Answer 3

Kg CO2 eq = A x EI, where A is source and EI is emission intensity

Question 4

What are the type of emissions?

Answer 4

• Direct emission (Things people do, see, use, etc.)
• indirect emission (Consequence from those actions)

Question 5

What are the two main perspective when investigating the emission?

Answer 5

• Production-based accounting (goods>humans>environment)
• Consumption-based accounting (emissions embedded in goods/services resulting from supply chain)

Question 6

Example of emission from 3 separated scopes

Answer 6

Scope 1: Direct emission (associated to energy use e.g. fuel burning)
Scope 2: Indirect emission (from electricity)
Scope 3: Indirect emission (from everything else e.g. materials)

Question 7

What are the difference between net and gross accounting?

Answer 7

Gross accounting is the total emissions while net emission is gross emission combined with emissions removal.

Question 8

What is a system?

Answer 8

Collection of things working together as a part of a whole

Question 9

What we need to consider when using system analysis?

Answer 9

• Relationships
• Perspective
• Influence

Question 10

Problems in system analysis:

Answer 10

Less agreement due to rising of complexity.
