Integrating life cycle thinking into business.
Long Trail Sustainability (LTS) is a North American sustainability consultancy focused on helping organizations turn environmental data into structured, defensible, and actionable insight.
We work across life cycle assessment, carbon accounting, compliance reporting, sustainability data systems, and training—connecting these capabilities into a unified approach that supports both technical rigor and real-world decision-making.
Our work sits at the intersection of methodology, software, and applied sustainability practice. We like to think of ourselves as a boutique sustainability firm; small and personable with a high level of in-house expertise yet expansible through our strong worldwide partner network of sustainability professionals.
What We Do
Most organizations don’t struggle with a lack of sustainability data—they struggle with connecting it.
LTS helps bridge that gap by supporting the full sustainability lifecycle:
- Life Cycle Assessment (LCA) to understand environmental impacts
- Carbon Accounting to quantify organizational and product emissions
- Compliance Reporting to translate data into ESG, EPR, and ISSB-aligned disclosures
- Sustainability Data Governance to improve structure, consistency, and auditability
- Reporting Readiness & Strategy to operationalize sustainability programs
- AI Enablement to scale analysis, reporting, and decision support
Rather than treating these as separate services, we help organizations connect them into a coherent system.
Software & Data: SimaPro and DATASMART
LTS is the North American distributor of SimaPro, one of the world’s leading life cycle assessment platforms.
We support organizations using SimaPro to model environmental impacts, manage sustainability data, and produce defensible results for reporting and decision-making.
We also develop and maintain DATASMART, a North American life cycle inventory (LCI) database designed specifically for regional relevance and methodological transparency. DATASMART enhances and extends existing datasets with critically reviewed processes and improved representation of North American energy systems, supply chains, and production conditions.
Together, SimaPro and DATASMART provide a strong technical foundation for LCA, carbon accounting, and sustainability reporting.
Training & Capability Building
Sustainability capability is not built through software alone.
LTS offers training programs and certificate courses designed for practitioners, analysts, and sustainability leaders who want to deepen both technical and strategic understanding.
Our training includes:
- Life Cycle Assessment (LCA) fundamentals and advanced practice
- Carbon footprinting and GHG accounting
- Sustainability data management and reporting systems
- Scaling sustainability programs within organizations
Our focus is on building methodological confidence, not just software proficiency.
Consulting & Advisory Services
Our consulting work supports organizations at every stage of their sustainability journey—from first assessments to enterprise-scale reporting systems.
We bring deep expertise in ISO-aligned methodologies, North American datasets, and applied sustainability practice.
Our services include:
- Life Cycle Assessment (LCA) and Product Sustainability Assessments
- Product and Organizational Carbon Footprinting
- ESG, EPR, and ISSB-aligned Reporting
- Environmental Product Declarations (EPDs) and critical reviews
- Sustainability data governance and reporting systems design
- Sustainability strategy and program development
We act as technical partners, helping organizations ensure their sustainability work is accurate, defensible, and usable in real decision-making contexts.
Our Approach
We don’t view sustainability as a single output or report.
We see it as a connected system:
LCA → Carbon Accounting → Reporting → Governance → Strategy → Enablement
When these pieces are aligned, organizations can move beyond fragmented analysis and toward scalable sustainability capability.
Working With LTS
We work with organizations across industries who are navigating increasing sustainability expectations—from regulatory reporting and customer requirements to internal sustainability strategy and product development.
Whether supporting a single product assessment or helping design a full sustainability data system, our goal is the same:
To make sustainability data more structured, more usable, and more defensible.
