Work out green region comparison instantly with clear inputs, formula shown and shareable results.
Grid carbon intensity varies by more than an order of magnitude between regions — from around 20 grams per kilowatt-hour in hydro or nuclear-dominated grids to over 600 in coal-heavy ones. Moving a workload to a low-carbon region is usually the single largest available emissions reduction, and the trade-off is latency for users far from that region.
Regional emissions
tonnes CO2 = kWh x grams per kWh / 1,000,000; saving = region A emissions - region B emissions
Frequently yes, and it is far cheaper. A tenfold difference in grid intensity dwarfs the 10 to 30 percent typically achievable through code and architecture optimisation.
Move the batch and asynchronous portions to low-carbon regions and keep only latency-critical serving close to users. Most workloads split this way more easily than expected.
