2. What is the primary purpose of an internal carbon price (ICP) within a corporate emission reduction strategy?
An internal carbon price assigns a monetary value to GHG emissions, making low-carbon options more financially attractive when evaluating capital projects or operational decisions.
3. What is the primary mechanism by which forests provide 'ecosystem services' relevant to climate change mitigation?
Forests sequester carbon by capturing atmospheric CO₂ through photosynthesis and storing it in wood, roots, litter, and soil, making forest conservation a key natural climate solution.
