Read the first 7 Environmental Impact flashcards as text

  1. Which approach does the GHG Protocol recommend for attributing Scope 2 electricity emissions when a company purchases renewable energy certificates (RECs)?

    Answer: Both location-based and market-based methods must be disclosed

    The GHG Protocol Scope 2 Guidance requires companies to report both location-based (grid average) and market-based (contractual instruments like RECs) figures for complete transparency.

  2. Permafrost thaw is considered a critical climate tipping point in environmental impact science primarily because:

    Answer: It releases large stores of methane and CO₂ previously locked in frozen ground

    Permafrost contains vast quantities of ancient organic carbon; as it thaws, microbial decomposition releases CH₄ and CO₂, creating a positive feedback loop that amplifies warming.

  3. When auditing a cement plant, which chemical process — distinct from fuel combustion — must be separately inventoried as a process emission?

    Answer: Calcination of limestone releasing CO₂

    Calcination converts calcium carbonate (limestone) to calcium oxide (lime) and releases CO₂ chemically — this process emission is separate from and in addition to combustion emissions.

  4. In environmental impact assessment, what does 'ecosystem services valuation' help carbon auditors understand?

    Answer: The economic and climate value of intact ecosystems in absorbing and storing carbon

    Ecosystem services valuation quantifies the climate benefit and broader value of intact ecosystems (forests, wetlands, grasslands) as natural carbon sinks and biodiversity reservoirs.

  5. A company reports a Science-Based Target (SBT) aligned with a 1.5°C pathway. This means the target:

    Answer: Is validated to cut emissions at a rate consistent with limiting global warming to 1.5°C

    SBTs validated by the Science Based Targets initiative (SBTi) as 1.5°C-aligned must demonstrate emission reductions consistent with the most ambitious Paris Agreement goal.

  6. Which environmental indicator measures the ratio of a company's carbon emissions to its economic output, allowing cross-sector comparisons?

    Answer: Carbon productivity (or carbon efficiency)

    Carbon productivity (or carbon efficiency) expresses economic output generated per unit of CO₂e emitted, enabling meaningful comparisons across companies and sectors of different sizes.

  7. Nitrous oxide (N₂O) emissions from agricultural soils are primarily driven by which process?

    Answer: Microbial nitrification and denitrification of nitrogen in soil

    Soil microbes convert nitrogen (from fertilizers, manure, or atmospheric deposition) through nitrification and denitrification, releasing N₂O — a GHG with a 100-year GWP of 273.
