From Scale to Specificity: Sustamize x Climatiq for Reliable Scope 3 Reporting

Expanding Access to Reliable CO₂ Data: The Sustamize x Climatiq Partnership

Companies today face growing pressure to deliver accurate Scope 3 reporting while meeting regulatory demands such as CSRD, CBAM, and the Digital Product Passport. The challenge: although plenty of emission factor data is already available from public databases or other providers — and much of it is reliable — it is often either outdated or only covers broad sector and regional averages.

The challenge is often in finding the up-to-date, product- and process-specific detail that companies need to calculate emissions precisely and truly reflect the climate impact of complex supply chains. This is particularly true for companies moving from spend-based emissions reporting to more accurate activity-based models. At the same time, sustainability data needs to be immediately usable in the software tools that teams across the business already depend on.

This is where the partnership between sustamize and Climatiq makes the difference. Climatiq already offers one of the largest collections of scientifically-vetted emission factors, delivered through high-performance APIs that integrate directly into platforms like Salesforce and Celonis. By adding sustamize’s bottom-up database – with more than 7 million emission factors across thousands of assets, such as over 3,200 metals, 1,000 composites, and 160 polymers – customers gain a new layer of specificity and granularity on top of Climatiq’s breadth. Each dataset is validated, standardized, and aligned with the GHG Protocol and ISO 14067, ensuring audit-ready compliance. Together, Climatiq and sustamize combine scale with specificity to unlock faster, more consistent, and more precise carbon reporting.

Together for Impact: Sustamize x Climatiq Enable Faster, Seamless PCF Calculations

At sustamize, we believe that real progress in sustainability comes from making data not only accurate, but also accessible and actionable. That is why our partnership with Climatiq is such a powerful step forward.

Climatiq already provides access to a wide range of reliable Scope 3 emission factors from established sources. What sustamize now adds is a unique bottom-up dataset that goes beyond averages to capture product- and process-level detail, updated biannually and fully documented for audit-ready compliance. Sustamize brings a uniquely comprehensive database that enables companies to build Product Carbon Footprints (PCFs) from the ground up.

This approach does more than calculate emissions, it reveals where the biggest optimization opportunities lie and creates the foundation for long-term PCF management. Our data is dynamic, updated twice a year, and spans an exceptionally wide range of materials, processes, and geographies, including recycling values that are crucial for realistic assessments.

By joining forces with Climatiq, we are making accurate Scope 3 calculations more accessible than ever. The proven quality and depth of sustamize’s data become instantly available through Climatiq’s platform, giving customers both speed and confidence in their sustainability reporting. Climatiq ensures extremely low latency and robust integration performance, so enterprises can rely on fast and consistent data delivery. With access to one of the largest databases of scientifically-vetted emission factors, all processed under rigorous normalization and quality standards, Climatiq guarantees accuracy and enterprise-grade reliability. Seamless integration through powerful APIs makes it simple for organizations to work with this data in their existing workflows.

Instead of juggling multiple sources (and the issues of mismatched data and units that come with that), businesses can now access all relevant, up-to-date PCF data in one place — reliable, transparent, and ready to integrate. Together, sustamize and Climatiq are not just making carbon data easier to calculate; we are empowering companies to act on it, identify reduction pathways, and manage their footprint in a way that drives real, lasting impact.

Customer Benefits: Accurate Scope 3 Reporting and Easier Compliance

With sustamize data available through Climatiq, companies gain a unique layer of depth and quality that makes Scope 3 reporting both accurate and efficient. Our CO₂e reference database is one of the most comprehensive and continuously updated worldwide. The level of granularity enables businesses to build complete Product Carbon Footprints (PCFs), identify carbon hotspots, and uncover optimization potential across their supply chains.

Key customer benefits include:

• Reliable and certified data: scientifically validated, quality-checked, and fully documented for audit-ready compliance.
• Comprehensive coverage: +150,000 datasets, 100,000 emission factor variants, and wide geographic/ material scope.
• No data gaps: With sustamize's dynamic approach, companies can obtain accurate emission factors for any defined region worldwide, even down to specific U.S. states or Chinese provinces.
• Optimization potential: complete PCF calculations that highlight carbon hotspots and reduction potential.
• Always up to date: dynamic datasets refreshed twice a year to reflect the latest standards and developments.
• Seamless integration: unified data formats and high-performance API access through Climatiq for fast and consistent delivery.
• Smart automation: AI-powered Autopilot that maps materials and components automatically to the right emission factors.
• Trusted compliance: full alignment with GHG Protocol, ISO 14067, and preparation for upcoming EU regulations.
• Strategic advantage: turning Scope 3 data into actionable insights for supplier evaluation, sourcing optimization, and long-term carbon management.

We empower cost engineers to optimize products with lower footprints, procurement teams to make better sourcing decisions, sustainability and ESG managers to report in line with GHG Protocol and ISO 14067, and finance teams to embed carbon data into core business metrics. In practice, this means every team — from operations to product development — can work with the same high-quality, unified database, closing information gaps and accelerating action.

Conclusion: Scale, Specificity, and Trustworthy Carbon Reporting

At the heart of the sustamize x Climatiq partnership lies a simple idea: businesses can only act on what they can measure. Climatiq already delivers scale, speed, and integration performance across industries. Sustamize now adds the specificity that organizations across sectors - from manufacturing and automotive to chemicals and packaging - as well as functions like sustainability management, procurement, and cost engineering have been missing: the product- and process-level detail needed for accurate PCFs and actionable Scope 3 strategies.

By uniting sustamize’s bottom-up methodology and continuously updated, scientifically-validated emission factors with Climatiq’s powerful APIs, low-latency performance, and broad software integrations, we are opening up new opportunities to improve carbon reporting across multiple industries. Ultimately, our goal is not just to simplify compliance, but to enable enterprises to manage and reduce their Product Carbon Footprints in a way that drives measurable, long-term impact.
