📌 Overview

Tracarbon is a Python library that tracks your device's energy consumption and calculates your carbon emissions.

It detects your location and your device automatically before starting to export measurements to an exporter. It could be used as a CLI with already defined metrics or programmatically with the API by defining the metrics that you want to have.

📦 Where to get it

# Install Tracarbon
pip install tracarbon

# Install one or more exporters from the list
pip install 'tracarbon[datadog,prometheus,kubernetes]'

🔌 Devices: energy consumption

Devices	Description
Mac	✅ Global energy consumption of your Mac (must be plugged into a wall adapter).
Linux	⚠️ Only with RAPL. See #1. It works with containers on Kubernetes using the Metric API if available.
Windows	❌ Not yet implemented. See #184.

Cloud Provider	Description
AWS	✅ Use the hardware's usage with the EC2 instances carbon emissions datasets of cloud-carbon-coefficients.
GCP	❌ Not yet implemented.
Azure	❌ Not yet implemented.

📡 Exporters

Exporter	Description
Stdout	Print the metrics in Stdout.
JSON	Write the metrics in a JSON file.
Prometheus	Send the metrics to Prometheus.
Datadog	Send the metrics to Datadog.

🗺️ Locations

Location	Description	Source
Worldwide	Get the latest co2g/kwh in near real-time using the CO2Signal or ElectricityMaps APIs. See here for the list of available zones.	CO2Signal API or ElectricityMaps
Europe	Static file created from the European Environment Agency Emission for the co2g/kwh in European countries.	EEA website
AWS	Static file of the AWS Grid emissions factors.	cloud-carbon-coefficients

⚙️ Configuration

The environment variables can be set from an environment file .env.

Parameter	Description
TRACARBON_CO2SIGNAL_API_KEY	The api key received from CO2Signal or ElectricityMaps.
TRACARBON_CO2SIGNAL_URL	The url of CO2Signal is the default endpoint to retrieve the last known state of the zone, but it could be changed to ElectricityMaps.
TRACARBON_METRIC_PREFIX_NAME	The prefix to use in all the metrics name.
TRACARBON_INTERVAL_IN_SECONDS	The interval in seconds to wait between the metrics evaluation.
TRACARBON_LOG_LEVEL	The level to use for displaying the logs.

🔎 Usage

Request your API key

• Go to CO2Signal and get your free API key for non-commercial use, or go to ElectricityMaps for commercial use.
• This API is used to retrieve the last known carbon intensity (in gCO2eq/kWh) of electricity consumed in your location.
• Set your API key in the environment variables, in the .env file or directly in the configuration.
• If you would like to start without an API key, it's possible, the carbon intensity will be loaded statistically from a file.
• Launch Tracarbon 🚀

Command Line

tracarbon run

API

from tracarbon import TracarbonBuilder, TracarbonConfiguration

configuration = TracarbonConfiguration() # Your configuration
tracarbon = TracarbonBuilder(configuration=configuration).build()
tracarbon.start()
# Your code
tracarbon.stop()

with tracarbon:
    # Your code

report = tracarbon.report() # Get the report
