TUNLEY ENVIRONMENTAL X PLANET FWD

Planet FWD and Tunley Environmental have partnered to provide a complete approach to product and corporate sustainability assessment. By combining Life Cycle Assessment (LCA), corporate carbon modelling, and independent technical review and assurance, we help organisations produce outputs that are robust, defensible, and ready for external use.

Whether supporting product LCA and critical review, corporate GHG reporting (ISO 14064), or regulatory requirements such as Extended Producer Responsibility (EPR) and packaging compliance, the partnership is designed to deliver high quality, defensible results with confidence.

WHY THIS PARTNERSHIP EXISTS

Across projects, both organisations bring strong capabilities in LCA modelling, data collection, and technical review. Responsibilities are assigned flexibly to ensure independence and the best fit for each project.

There is also a combined platform and services strength through the partnership. Planet FWD's software-driven approach delivers LCAs and Scope 3 accounting at portfolio scale, while Tunley provides expert-led service rigour. Together, customers get both efficiency and depth.

By combining these capabilities, we ensure that sustainability assessments are completed to a high standard and are independently reviewed and verified for external use.

The partnership exists to combine:

Shared expertise in Life Cycle Assessment (LCA) modelling, data collection, and sustainability analysis, enabling the development of robust assessments
Shared capability in independent technical review, ensuring reports are critically evaluated, validated, and ready for external use
Complementary strengths across delivery and verification, allowing roles to be flexibly assigned to maintain independence while achieving the best outcome for each project

Planet FWD:

Planet FWD is a sustainability management platform purpose-built for consumer brands and B2B companies managing product-level LCAs and corporate GHG inventories at portfolio scale. The software produces ISO 14040/44 compliant LCAs, PACT v3 conformant Product Carbon Footprints (PCFs), and Scope 1-3 corporate inventories aligned with the GHG Protocol.

These outputs support a range of use cases across regulatory and certification contexts, including Extended Producer Responsibility (EPR), California SB 253, B Lab Climate Action standards, CSRD, and more.

Within the partnership, Planet FWD and Tunley can each lead on LCA delivery or provide independent technical review of work developed by the other partner or by a third party, depending on project requirements. This flexibility ensures that reports are robust in development and appropriately reviewed for external use.

Tunley Environmental:

Tunley Environmental is a science-based environmental sustainability consultancy, bringing deep expertise in both LCA delivery and independent technical review and assurance. This includes conducting ISO 14040/44 LCAs as well as providing critical review through formal panels or as an independent expert reviewer.

Within the partnership, Tunley can lead on either LCA modelling or independent assurance, depending on the project's needs. For clients, this arrangement creates a more streamlined route to delivering life cycle sustainability assessments, ensuring reports are developed, reviewed, and verified to a high standard without the need to manage multiple providers.

PLANET FWD PROVIDED WITH INDEPENDENT VERIFICATION

Planet FWD is a leading climate tech company that helps businesses measure, reduce, and communicate the environmental impact of their products. Planet FWD approached Tunley Environmental to provide an independent critical review of a comparative life cycle assessment (LCA).

Our role was to validate and verify the assessment against international standards, ensuring it met the criteria required for approval and public disclosure. In line with ISO 14044, our team carried out a full critical review with a panel of experts and a chairperson, carefully assessing the methodology, data selection, and interpretations. This assurance confirmed that the study was scientifically robust, transparent, and fully compliant with ISO 14040 and 14044 standards.

Through this process, Tunley provided Planet FWD with the independent verification needed to confidently share their findings, strengthening the credibility of their sustainability insights and reinforcing trust with their client.

WHAT THIS PARTNERSHIP DELIVERS

1. LCA modelling plus independent critical review

Planet FWD and Tunley Environmental both have strong capabilities in LCA modelling and independent critical review. Responsibilities are allocated to maintain independence and ensure the best project fit.

This includes a detailed assessment of:

Data sources
Methodologies and assumptions
Calculations and outputs
Interpretation of results
Transparency and reporting
Compliance with ISO 14040/44

The process involves iterative review cycles through to finalisation.

2. Support for EPR and Packaging Compliance

The partnership supports organisations navigating Extended Producer Responsibility (EPR) requirements and packaging compliance.

We help organisations:

Assess the environmental impact of packaging formats
Support ecomodulation strategies and potential fee reductions
Prepare for evolving regulatory requirements
Strengthen evidence for compliance and reporting

This provides a more reliable foundation for decision making and regulatory engagement.

3. Independent review/assurance for corporate carbon reporting and related disclosures.

This partnership supports corporate carbon reporting assurance (e.g. ISO 14064). One organisation leads Inventory Management Plan (IMP) development, data collection, and emissions calculations (including complex Scope 3), while the other provides independent review and assurance, assessing methodology, data quality, boundaries, and compliance with the GHG Protocol and ISO 14064 (Parts 1 and 3).

The result is verification statements prepped for regulators or assurance opinions for public disclosure. CARB accepts ISO 14064-3, and the partnership delivers a complete solution combining robust inventory preparation with independent assurance. It also supports broader requirements such as CDP, SBTi, EcoVadis, investor requests, and credible external communications.

Relevance to California SB 253
For companies operating in California with >$1B revenue:

2026 (FY2025 data): Scope 1 & 2 disclosure required (assurance optional but often used).
2027 onwards: Limited assurance required for Scope 1 & 2; Scope 3 reporting begins.
2030: Reasonable assurance required for Scope 1 & 2 (Scope 3 under discussion).

WHY COMPANIES CHOOSE THIS PARTNERSHIP

Companies choose Tunley Environmental and Planet FWD when they need more than a standard audit and require technical independent review, expert consultancy, and close collaboration between inventory development and independent review. Our approach prioritises scientific prowess and tangible improvements, ensuring reports are robust and verified.

For organisations that prioritise brand recognition, high volume audit delivery, or global accreditation under a single provider, larger firms such as SGS or BSI may be preferred. In contrast, this partnership is designed for those who value technical depth, flexibility, and hands-on expertise.

What we deliver

Sustainability assessments supported by high-quality data
Independent critical review of Life Cycle Assessments (LCAs)
EPR-related support where reviewed LCAs are required or beneficial
Independent review and assurance for carbon and environmental reporting
Greater confidence in outputs used for external disclosure and decision-making
