The European Union's Carbon Border Adjustment Mechanism (CBAM) is a regulatory tool designed to measure carbon emissions attributed to the production of high-carbon goods imported into the EU, aiming to promote cleaner practices in industrial production across non-EU countries. To this end, the European Commission publishes emission factors providing the necessary metrics for compliance and environmental integrity.

Cloud Carbon Footprint is a free and open-source emissions measurement and analysis tool. It provides emission factors and methodology for measuring the emissions of Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).

Climate TRACE (Tracking Real-Time Atmospheric Carbon Emissions) is a collaborative initiative aimed at providing precise, real-time tracking of global greenhouse gas emissions using artificial intelligence, satellite image processing and other remote sensing technologies along with academic research and publicly available data.

ecoinvent is a Swiss not-for-profit association that provides a Life Cycle Inventory (LCI) database that supports various types of sustainability assessments. This data enables users to gain a deeper understanding of the environmental impacts of their products and services.

EXIOBASE is a global, detailed Multi-Regional Environmentally Extended Supply-Use Table (MR-SUT) and Input-Output Table (MR-IOT). It was developed by harmonising and detailing supply-use tables for a large number of countries, estimating emissions and resource extractions by industry. Subsequently, the country supply-use tables were linked via trade creating an MR-SUT and producing MR-IOTs from this. The MR-IOT can be used for the analysis of the environmental impacts associated with the final consumption of product groups.
