CCA Emissions Measurement & Verification 2

Question 1

Which ISO standard specifies requirements for verifying and validating greenhouse gas statements?

Accepted Answer

ISO 14064-3

Answer

ISO 14064-3 gives the specification and guidance for verification and validation of GHG statements.

Question 2

Under a reasonable assurance engagement, how is the verifier's opinion typically worded?

Accepted Answer

Positively, stating the GHG statement is fairly presented in all material respects

Answer

Reasonable assurance produces a positive-form opinion, while limited assurance uses negative-form wording.

Question 3

A facility burns fuel containing 0.80 metric tons of carbon per ton of fuel and assumes full oxidation; how much CO2 is emitted per ton of fuel?

Accepted Answer

2.93 t CO2

Answer

Multiplying carbon by the molecular weight ratio 44/12 gives 0.80 × 3.667 ≈ 2.93 t CO2.

Question 4

Under EPA's GHG Reporting Program (40 CFR Part 98), what is the general annual reporting threshold for most source categories?

Accepted Answer

25,000 metric tons CO2e

Answer

Most facilities must report under Part 98 if they emit 25,000 metric tons CO2e or more per year.

Question 5
