Answer: All of these
CBDCs are sovereign digital currency: issued by central banks, legal tender status, regulated monetary policy. Cryptocurrencies are decentralized, volatile, and largely unregulated. Critical for understanding digital money evolution.
Answer: True
e₹ (e-Rupee) is RBI-issued digital token representing sovereign currency. Two types: retail (e₹-R) for public transactions via wallets, wholesale (e₹-W) for interbank settlements. Built on distributed ledger technology.
Answer: All of these
Forest monitoring combines: satellite imagery (Sentinel, Resourcesat), GIS for spatial analysis, AI for change detection. Used for REDD+ programs and climate reporting. Critical for environmental governance.
Answer: Effectiveness / PUE
PUE = Total Facility Energy / IT Equipment Energy. Ideal PUE is 1.0; modern data centers achieve 1.1-1.3. Critical for measuring and improving data center sustainability.
Answer: Both A and B
Gold Standard and Verra's Verified Carbon Standard (VCS) certify offset projects: renewable energy, forestry, methane capture. Ensure real, measurable, additional emission reductions. Critical for carbon market integrity.
Answer: True
