Mapbox has been actively working to reduce its carbon footprint by analyzing and offsetting emissions across various aspects of its operations, including its cloud computing infrastructure, primarily hosted on AWS. While AWS has surpassed 50% renewable energy use, it is not fully carbon-neutral, but aims to be by 2030. To better understand and manage emissions from its AWS usage, Mapbox collaborated with Chris Adams from the Green Web Foundation to develop the Green Cost Explorer, which leverages AWS's Cost Explorer API to provide detailed insights into carbon usage per service and region. This tool allows Mapbox to identify carbon-intensive services and potentially shift workloads to more sustainable AWS regions, although considerations like data transfer and user locality are crucial. Furthermore, Mapbox enhances compute efficiency using containerized infrastructure via Docker on AWS ECS, and encourages learning about sustainable tech practices as part of its broader commitment to environmental responsibility.
