Green software: How can tech contribute to worldwide sustainability effort?
summary
Tech industry emits ~2% of global CO2, rivaling aviation, so software must cut its share by measuring and acting on concrete metrics: CO2 equivalent for emissions and Software Carbon Intensity per functional unit. Uses include an open-source Carbon Footprint tool and the Carbon Aware SDK for forecasting and location-aware scheduling. Practical patterns shown: cache static assets, retention policies, serverless for spiky ML, queue non‑urgent work, optimize image sizes; experiments include carbon-aware workflow schedulers and GPU-power throttling for DNN training.
