compare_carbon_prices
compare_carbon_pricesRead-onlyIdempotent
Purpose: put every carbon price snapshot side by side - market/basis, value, unit, price date and source - and compute the spread within each currency. Guidelines: use for "how do EU and China carbon prices compare" or "what is the spread between auction and secondary prices"; same-currency spreads are returned as computed values. Limits: currencies are NOT converted - the tool deliberately does not produce a cross-currency difference, because that requires an FX rate the dataset does not carry; prices are dated snapshots, not live quotes. Ex: compare_carbon_prices(), compare_carbon_prices(language='en').
