Sustainability software, training, and expertise

Industry-Leading Tools

The tools and data behind credible environmental analysis.

Access SimaPro, one of the world’s leading LCA platforms, alongside DATASMART, LTS’s North American life cycle inventory database. Together, they provide the regional specificity, transparency, and data quality needed for LCAs, EPDs, ESG disclosures, EPR programs, and ISSB-aligned reporting. This combination supports more representative modeling of North American supply chains, improving the credibility and defensibility of environmental results. It also helps practitioners move beyond generic datasets to more accurately reflect real-world production systems, energy mixes, and regulatory contexts.

Life Cycle Assessment

Generate product-level environmental insights

Life Cycle Assessment (LCA) provides a data-driven view of environmental impacts across a product’s life cycle. By evaluating materials, production processes, energy use, distribution, and end-of-life pathways, LCA identifies key impact drivers and improvement opportunities.

LTS supports organizations with practitioner-led expertise, North American-specific data, and ISO-aligned methodology to ensure results are transparent, accurate, and defensible.

LEARN MORE

Compliance Reporting

Translate LCA data into ESG, EPR & ISSB disclosures

Compliance reporting translates environmental data into structured disclosures aligned with ESG, EPR, and ISSB requirements. It ensures that technical LCA results are converted into credible, audit-ready reporting outputs.

LTS supports organizations in developing transparent, defensible reporting aligned with evolving regulatory and customer expectations.

LEARN MORE

Sustainability Data Governance

Structure, validate, and control sustainability data

Effective sustainability reporting depends on structured, consistent, and well-governed data. LTS helps organizations establish frameworks that improve data quality, traceability, and accountability across sustainability datasets.

This ensures sustainability data is reliable, scalable, and suitable for both internal decision-making and external reporting.

LEARN MORE

Reporting Readiness

Prepare systems for scalable disclosure and auditability

Reporting readiness ensures that sustainability data, methodologies, and workflows are structured for consistent and defensible disclosure. LTS supports organizations in aligning internal systems with ESG, EPR, and ISSB-aligned reporting requirements, enabling repeatable and transparent reporting processes. We help translate technical sustainability data into formats suitable for external disclosure, audit, and stakeholder communication, reducing friction as reporting demands continue to evolve.

AI Enablement

Automate workflows using trusted sustainability data

AI enablement builds on strong data governance and reporting foundations to support automation, analytics, and decision support. LTS helps organizations prepare structured sustainability data that can be safely used in AI-driven systems.

This enables faster analysis, improved reporting efficiency, and enhanced sustainability insights without compromising methodological rigor.

Testimonials

“I have earned four LCA and SimaPro certificates (total ten courses) from LTS (formerly EARTHSHIFT). These trainings have provided me a very strong foundation on both the SimPro software and the LCA methodology. The course materials are outstanding and useful. Additionally, the instructor is remarkable, knowledgeable, and very helpful. The education I received from LTS through taking these classes is enormously valuable as it has undoubtedly prepared me to become a sophisticated LCA practitioner.”

Eric TanSenior Research Engineerhttp://#–National Renewable Energy Laboratory (NREL)

“Our recent Life Cycle Assessment of the Denali jacket has helped our product development teams validate the environmental impact reductions achieved through the use of recycled polyester and a new dyeing process which uses up to 50% less water and chemicals and 25% less energy on average versus traditional dyeing methods. Our product development teams can now utilize the learnings from the LCA and quickly evaluate future design changes.”
