Sustainability

The Sustainability tab in Analytics provides a real-time view of the environmental impact of your voice AI operations. Monitor CO2 emissions, energy consumption, and the benefits of hosting on low-carbon infrastructure.

Accessing Sustainability Metrics

Navigate to Monitor > Analytics and click the Sustainability tab (next to Overview).

KPIs

The dashboard displays 6 key performance indicators:

How Emissions Are Calculated

Emissions are computed from three components of the voice AI pipeline: Energy consumption is calculated per component and then converted to CO2 using the carbon intensity of the datacenter’s electricity mix. Callem’s infrastructure runs on low-carbon energy (92% from nuclear, hydro, wind, and solar).
TTS cache hits produce zero emissions. When a TTS response is served from cache, no GPU compute is needed. The dashboard only counts uncachedChars.

Charts

CO2 Emissions Over Time

A stacked area chart showing daily emissions broken down by component (LLM, TTS, STT). Hover to see exact values.

Breakdown by Component

A donut chart showing the percentage split between LLM, TTS, and STT emissions.

CO2 by Agent

A horizontal bar chart ranking agents by total emissions. Useful for identifying which agents consume the most resources.

CSRD Compliance

The Sustainability dashboard supports CSRD (Corporate Sustainability Reporting Directive) reporting requirements:
Per-model and per-provider coefficients will be available in future updates for more granular reporting.
