Global Emissions Data For Today’s Carbon Challenges
Cutting-Edge Approaches,
Scientifically Reviewed
TASA’s team of scientists are led by Dr. Yi Yang, world renowned EEIO expert and lead author of the original U.S. EEIO model. All TASA-EFX EEIO models follow consistent and rigorous methodologies that have been published in leading peer-reviewed technical journals.
Accurate & Reliable
Robust national accounts data – from which input-output models are constructed – are not available universally. TASA currently provides a core set of 12 unique national models (~70% of Global GDP) leveraging primary, high-resolution, original data. From these, extended models are developed for geographies where input-out infrastructure and emissions reporting are lacking, or non-existent. TASA-EFX surpasses traditional methods by integrating more representative technological and socioeconomic production systems, resulting in emissions data of unmatched accuracy and reliability.
High-Quality Source Data
TASA’s scientists leverage extensive economic and environmental data sources developed by governments, academics, and commercial and nonprofit organizations to ensure that the highest-resolution and most recently available data is made available for reporting, target-setting, and mitigation. Crucially, TASA-EFX’s disaggregated multi-tier structure supports deep hybrid-path exchange, enabling users to align emissions estimates with the specific realities of their own unique supply chains.
Conforms with All Leading Regulatory & Global Standards
The comprehensiveness and granularity of TASA-EFX data allows for regional, technological, and organizational customization for corporate reporting and target setting. The structure and flexibility of TASA’s National and rLCA models conforms with the evolving guidance provided by the GHG Protocol, the Corporate Sustainability Reporting Directive (CSRD), International Sustainability Standards Board (ISSB), Science Based Targets Initiative (SBTi), and others.
Get It Right the First Time
Avoid Costly Restatements
Particularly with scope 3 accounting, some practitioners will apply single region emissions factors (e.g., global averages or single-country values), while others might use highly aggregated globalized data that relies on the economic relationship and technical context of a single economy. Each of these practices can lead to large errors in accounting. TASA-EFX mitigates the risk of misreporting your carbon footprint.
How big is the risk?
In today’s global economy, companies source components from diverse locations, with emissions profiles varying two- to fourfold across sourcing geographies. As regulators and standards bodies increasingly demand geographic and technological specificity, correcting misreported emissions can become both complex and costly.
Metals Example: A company using U.S. EEIO data to approximate the scope 3 emissions embodied in metals purchased from China could be underestimating emissions by a factor of 10.
Common Reporting Applications
of TASA-EFX
TASA-EFX data are typically deployed in audit-grade scope 3 emissions calculations and are often the primary source of data used to calculate the following scope 3 categories under the GHG Protocol Standard:
Categories 1 & 2
Procurement and general ledger data tied to purchased goods, services, and capital assets often represent 60–90% of total emissions.
Categories 4 & 9
Upstream and downstream transportation, when distance and shipment weight data isn’t available.
Category 5
Waste, if there is no other material or activity data available on waste treatment.
Category 15
Investment-related emissions resulting from a company’s lending, investing and financial asset holdings.
