CSC Carbon Management & GHG Accounting 2 — Questions and Answers
Question 1: What is a 'carbon offset' in the context of carbon management?
- A government-imposed tax on each ton of CO2 emitted
- A verified reduction or removal of emissions used to compensate for emissions elsewhere (Correct answer)
- A type of renewable energy certificate tied to electricity generation
- A regulatory cap on total emissions for a specific industry sector
Correct answer: A verified reduction or removal of emissions used to compensate for emissions elsewhere
A carbon offset is a verified reduction, removal, or avoidance of greenhouse gas emissions in one location that is used to compensate for emissions occurring at another location.
Question 2: The Science Based Targets initiative (SBTi) requires corporate emissions reduction targets to align with which climate goal?
- Achieving absolute zero emissions within 10 years of joining
- Limiting global temperature rise to well below 2°C above pre-industrial levels (Correct answer)
- Reducing only Scope 1 and 2 emissions by 50% from a 2010 baseline
- Meeting individual country NDC (Nationally Determined Contribution) targets
Correct answer: Limiting global temperature rise to well below 2°C above pre-industrial levels
SBTi requires companies to set emissions reduction targets consistent with the level of decarbonization needed to limit global warming to well below 2°C, and ideally 1.5°C, above pre-industrial levels.
Question 3: Which of the following is an example of a voluntary carbon market certification standard?
- EU Emissions Trading System (ETS)
- Verified Carbon Standard (VCS) / Verra (Correct answer)
- Clean Air Act Title IV Acid Rain Program
- OSHA Process Safety Management Standard
Correct answer: Verified Carbon Standard (VCS) / Verra
The Verified Carbon Standard (VCS), administered by Verra, is a leading voluntary carbon market standard that certifies carbon offset projects and issues tradeable carbon credits.
Question 4: What is the primary conceptual difference between a carbon tax and a cap-and-trade system?
- Carbon taxes apply only to electricity generation while cap-and-trade covers all sectors
- A carbon tax sets a price per ton of emissions while cap-and-trade sets a ceiling on total emissions (Correct answer)
- Cap-and-trade systems generate no government revenue while carbon taxes do
- Carbon taxes are used internationally while cap-and-trade is only domestic
Correct answer: A carbon tax sets a price per ton of emissions while cap-and-trade sets a ceiling on total emissions
A carbon tax sets a direct price per metric ton of CO2 emitted, giving emitters flexibility on quantity; a cap-and-trade system sets a fixed cap on total emissions and lets companies trade allowances within that limit.
Question 5: What does the term 'carbon neutrality' mean when applied to an organization?
- The organization emits zero greenhouse gases from all owned facilities
- The organization balances total GHG emissions with equivalent offsets or removals (Correct answer)
- The organization uses 100% renewable energy for electricity and heating
- The organization has eliminated all Scope 1 emissions through efficiency measures
Correct answer: The organization balances total GHG emissions with equivalent offsets or removals
Carbon neutrality means an organization balances the total amount of greenhouse gas it emits by purchasing equivalent offsets or achieving equivalent carbon removals, resulting in a net-zero carbon impact.
Question 6: Which methodology is most commonly used to calculate the carbon footprint of a product across its entire lifecycle?
- Environmental Impact Assessment (EIA)
- Life Cycle Assessment (LCA) (Correct answer)
- Carbon Disclosure Project (CDP) reporting
- ISO 50001 Energy Audit methodology
Correct answer: Life Cycle Assessment (LCA)
Life Cycle Assessment (LCA) evaluates the environmental impacts—including carbon footprint—of a product from raw material extraction through manufacturing, use, and end-of-life disposal.
Question 7: What is 'additionality' in the context of carbon offset projects?
- A requirement that offset projects generate additional renewable energy capacity
- The requirement that an offset project reduces emissions beyond what would occur without the offset incentive (Correct answer)
- An accounting rule for adding Scope 3 Category 15 investment emissions
- The additional disclosure required when reporting carbon credits to regulators
Correct answer: The requirement that an offset project reduces emissions beyond what would occur without the offset incentive
Additionality requires that the emissions reductions from a carbon offset project would not have occurred in the absence of the carbon market incentive—the reductions must be 'additional' to a business-as-usual scenario.
