Open core AI toolkit
AI-powered sustainability report analysis
Analyze ESRS disclosures, assess climate risk, and benchmark companies — with full control over models, frameworks, and data.
Use cases
Upload any sustainability report and let OSA extract structured, evidence-based answers.
ESRS analysis
Understand how companies disclose under the European Sustainability Reporting Standards — with structured answers, evidence, and gap detection.
Climate risk assessment
Assess how companies identify, manage, and report on physical and transition climate risks across their operations and value chain.
Sustainability benchmarking
Compare disclosure quality and performance across companies, sectors, or reporting years — systematically and at scale.
Greenwashing detection
Identify vague claims, missing evidence, and inconsistencies in sustainability reports to surface potential greenwashing.
Bring your own framework
Use built-in frameworks like TCFD and ESRS, or define custom question sets tailored to your research or compliance needs.
How it works
From PDF upload to structured results — you stay in control at every step.
Upload reports
Upload sustainability reports as PDFs. Analyze one or batch-process multiple.
Choose a framework
Select a preset question set (ESRS, TCFD, and more) or create your own.
Analyze
Get explainable answers with evidence, source references, and identified gaps.
Export & compare
Export results as CSV for further analysis or compare across companies and configurations.
Open core, built to inspect
The analysis engine is open source — you can audit every step, extend the pipeline, and run it on your own terms. Enterprise features like API access, managed search backends, and job processing are available separately. Developed with research partners to keep methods reproducible and aligned with current ESG standards.
Experimentation framework
Compare models, chunk sizes, retrieval parameters, and question sets side by side to find the best configuration for your data.
AI model evaluation
Evaluate your full pipeline against ground truth research datasets to measure accuracy, coverage, and reliability.
Research collaboration with SRN
We work with the Sustainability Reporting Navigator — an academic platform by researchers at LMU Munich, University of Cologne, and others — to integrate expert-labeled sustainability data and benchmarks with OSA's open analysis pipelines.
