How this figure is calculated
The year-on-year percentage change in Nitrous oxide (N2O) emissions from Transport (Energy) (Mt CO2e). Computed from consecutive annual observations; years either side of a gap are skipped rather than bridged.
Computed from
- Nitrous oxide (N2O) emissions from Transport (Energy) EDGAR (Emissions Database for Global Atmospheric Research) Community GHG Database, Joint Research Centre (JRC) - European Commission
Statizoid computes this series; the underlying measurements belong to the publishers named above. The arithmetic is applied to every country and year where both inputs report, and nothing is estimated unless the page says so.
