BreezoMeter Pollen vs UK Carbon Intensity
BreezoMeter's Pollen API was folded into Google Maps Platform after Google's 2023 BreezoMeter acquisition; the old docs.breezometer.com host now redirects straight to Google's own Pollen product page. The live gateway, pollen.googleapis.com, still serves the same daily pollen forecast and heatmap-tile data for a location, just under a Google Cloud API key and Maps Platform billing.
This is the official carbon intensity forecast and outturn API for Great Britain's electricity grid, published by National Grid ESO, giving live and forecast gCO2/kWh figures nationally and regionally. It's a fully open government data feed with no key required.
