▶ Play the carbon storySource: "Monthly electricity data, Ember" (CC-BY-4.0), ingested continuously into the Voltcast production database. Intensities are generation-weighted: Σ emissions ÷ Σ generation across all tracked countries — a country average would flatter small clean grids and hide the giants. Monthly statistical data, labeled estimated wherever it appears in our products. Cite as "Voltcast Research, voltcast.com/research/global-carbon-2022".
