Sustainability Assessment Experts
Assess.
Quantify.
Verify.
Environmental and carbon assessment based on internationally recognized standards and methodologies.
We provide robust, science-based assessments of environmental impacts and greenhouse gas emissions, applying internationally recognized standards, methodologies, and life cycle approaches.
Expertise
Sustainability needs robust assessment.
Sustainability decisions require robust data, transparent methodologies and clearly defined system boundaries. LW&P combines scientifically sound assessment methods with many years of hands-on experience in consulting, research, standardization and verification.
Our core expertise lies in Life Cycle Assessment, Carbon Accounting and the methodological assessment of climate mitigation and carbon removal projects. We work on the basis of internationally recognized standards and, where required, project-specific methodologies and registry requirements.

Services
Quantitative sustainability assessment across products, organizations and projects.
We provide scientifically grounded environmental assessments and carbon accounting for products, organizations and climate projects — based on recognized standards and transparent methodologies. Beyond assessment, we guide our clients through external validation, verification and certification, combining technical expertise with first-hand experience as lead auditors and verifiers.
01
LCA & EPD
Understand environmental impacts across the entire life cycle.
We deliver Life Cycle Assessments (LCA) for products, processes and technologies — from screening and comparative assessments to comprehensive LCA studies and Environmental Product Declarations (EPD). We support our clients throughout the entire process, from modeling to successful external verification.
Methodological basis
ISO 14040 · ISO 14044 · ISO 14025 · EN 15804
Applicable product- and sector-specific standards and Product Category Rules (PCRs)
02
Carbon Footprint
Quantify greenhouse gas emissions and create a robust basis for decision-making, disclosure and reporting.
LW&P develops Corporate and Product Carbon Footprints (CCF and PCF) and robust carbon accounting models — including data structures, emission factors, calculation methodologies and transparent documentation.
Methodological basis
GHG Protocol · ISO 14064-1 · ISO 14067 · ISO 14068-1 · Industry-specific standards
03
Climate Projects
Quantify emission reductions and carbon removals against a baseline scenario.
LW&P develops and reviews accounting approaches for climate mitigation and carbon removal projects. Key aspects include baseline setting, additionality, project emissions, leakage, permanence, uncertainty and monitoring.
Our expertise covers technical mitigation projects as well as land use, forestry, soil carbon and other carbon removal approaches.
Methodological basis

APPROACH
Complex products. Clear process.
Reliable sustainability assessment requires more than a calculation. We follow a structured, step-by-step process — from defining the right question and system boundaries to robust modeling, reporting, communication and external review.
01
Scope
Define the assessment framework.
We start with a half-day online scoping workshop to define the assessment objective, functional unit, system boundaries, methodological framework, data requirements and intended use of the results.
02
Collect & assess data
Build a robust data basis.
We collect activity data and emission factors, establish a structured data inventory and assess data quality, completeness and representativeness.
03
Build the model
Develop a transparent LCA model.
We develop the Life Cycle Inventory (LCI) based on transparent input/output flows and model the relevant processes, products and value chains in an appropriate software.
04
Assess impacts
Quantify potential environmental impacts.
We quantify potential environmental impacts through Life Cycle Impact Assessment (LCIA), applying appropriate impact assessment methods and indicators.
05
Document & discuss
Provide transparent results.
We prepare a transparent technical report covering methodology, data, assumptions, limitations and results, followed by an online presentation and discussion of the findings.
06
Translate results into deliverables
One assessment – multiple outputs.
The assessment provides the technical basis for further deliverables — including EPDs and other program-specific reports, technical summaries for decision-makers, and accessible, evidence-based communication for external audiences in line with applicable requirements, including EmpCo.
07
Support third-party review
From preparation to successful verification.
We initiate and support external validation, verification, certification and other third-party reviews — from preparing the documentation to addressing findings and technical questions.
08
Iterate when needed
Incorporate changes and finalize the assessment.
Assessments often evolve as processes, recipes or data change. Our approach therefore includes two iterations to incorporate relevant changes and finalize a consistent assessment.
OUTCOME
One robust assessment. Multiple uses.
A transparent, traceable and reusable assessment model provides the foundation for technical decisions, programme-specific reporting, external communication and independent verification.

Standards & Methodologies
International standards. Recognized methodologies. Transparent assumptions.
The applicable methodology is defined by the objective, scope and intended use of each assessment, as well as by the specific requirements of relevant programs, standards or registries.

Why LW&P
Assessment expertise instead of
generic sustainability consulting.
LW&P focuses on quantitative sustainability assessment, robust methodologies and verifiable results. We combine scientific expertise with practical experience in standards, carbon accounting and verification.
Scientific foundation
Scientifically grounded assessment of complex environmental and climate-related questions.
Standards expertise
Extensive experience with international ISO standards, accounting frameworks and methodological requirements.
Verification perspective
A clear understanding of traceability, data quality, uncertainty and the evidence required for robust verification.
Practical application
Assessment methods designed to produce results that are useful for product development, management decisions, communication and verification.
About
Specialized expertise. Independent perspective.
LW&P is a specialized consultants network for Life Cycle Assessment, Carbon Accounting and Sustainability Assessment.
We combine expertise in engineering and environmental sciences, life cycle assessment, climate mitigation and carbon removal projects, standardization and verification.
Depending on the project, we work with a network of specialized experts to bring together the methodological and technical knowledge required for complex assessment tasks.
We have extensive experience working with innovators, start-ups and scale-ups, including projects at the edge of innovation where established standards and methodologies do not yet fully fit. We help our clients navigate this methodological frontier, develop robust and defensible approaches, and guide them through the assessment and verification process.
Our approach is independent, methodologically rigorous and focused on producing results that are transparent, traceable and useful in practice.
