ESG AI 30/60/90 Implementation Plan

Phase 1: Days 1-30 — Foundation and first pilot

The first 30 days are about three things: choosing the right first workflow, selecting tools, and running your pilot.

Week 1: Choose your first workflow

Based on everything we have covered, the recommended first workflow for most ESG teams is supplier sustainability questionnaire extraction for Scope 3 data collection. This is the right starting point because:

• It is your biggest time sink (hundreds of hours per cycle)
• It has a clear input (documents) and output (structured data)
• It requires no integration with enterprise systems
• Results are measurable within weeks
• It feeds every downstream workflow (carbon accounting, reporting, supply chain risk)

If supplier data collection is not your primary pain point, choose the workflow that meets these criteria: high volume, document-based, repeatable, and measurable.

Week 2: Select your tools and establish data governance

You do not need enterprise AI infrastructure for the pilot. You need:

1. An AI tool that can process documents: Claude, GPT-4, or equivalent. Ensure the tool's data handling meets your organisation's requirements — review the provider's data processing agreement, confirm whether your data is used for model training (opt out if so), and check data residency requirements.

2. A structured output template: Define exactly what data points you need extracted, in what format, with what validation rules. This was covered in Module 3.

3. A documentation protocol: From day one, capture every prompt you use, every AI output, and every human review decision. This is your audit trail.

Work with your IT and legal teams to confirm the tool is approved for use with ESG data. This step often takes the longest — start it in Week 1.

Weeks 3-4: Run the pilot

Process 50-100 supplier questionnaires using your AI-assisted workflow. Simultaneously, have a team member process a subset (20-30) manually using your current approach. Compare:

• Time per questionnaire (AI-assisted vs manual)
• Accuracy (spot-check AI extractions against source documents)
• Completeness (percentage of fields successfully extracted)
• Flagging quality (did AI correctly identify missing data, ambiguous units, and anomalies?)

Document everything. You will need these results for the business case presentation at the end of Phase 1.

Data governance for ESG metrics

Data governance is not a separate workstream — it is embedded in everything you do from day one. For ESG teams using AI, data governance covers four areas:

Data classification. Not all ESG data has the same sensitivity. Supplier-specific emissions data may be commercially confidential. Employee diversity data is personally identifiable. Board governance information may be material non-public information before disclosure. Classify your ESG data and ensure your AI tool selection and usage protocols match the classification.

Input controls. Define what data can be processed through AI tools. Establish rules about: what document types are approved for AI processing, whether personal data (employee names, contractor details) must be redacted before processing, and whether competitively sensitive supplier data requires additional protections.

Output controls. AI-generated outputs should never go directly into a disclosure without human review. Establish a review protocol: who reviews AI outputs, what they check for, how they document their review, and who has authority to approve data for disclosure.

Retention and traceability. Retain all inputs, prompts, AI outputs, and human review records for at least the assurance retention period (typically 5-7 years). This creates the audit trail that assurance providers need.

A practical governance checklist for your pilot:

• AI tool data processing agreement reviewed and approved by legal
• Data classification applied to all ESG data types
• Redaction protocol established for sensitive data
• AI output review protocol documented
• Retention policy defined for AI inputs and outputs
• Pilot participants trained on governance requirements

Phase 2: Days 31-60 — Scale and expand

By day 30, you should have pilot results demonstrating that AI-assisted supplier data extraction saves significant time and improves accuracy. Phase 2 scales the pilot to production and expands to additional workflows.

Weeks 5-6: Scale the pilot to full production

Move from 50-100 test questionnaires to your full supplier base. This means:

1. Process all incoming supplier questionnaires through the AI workflow. Refine your prompts based on what you learned in the pilot — edge cases, format variations, and common extraction errors.

2. Implement the gap analysis workflow from Module 3. Run it mid-cycle to identify non-responsive suppliers and missing data points. Generate and send AI-drafted follow-up communications.

3. Connect extraction outputs to your carbon accounting workflow. The structured data from supplier extraction should feed directly into your Scope 3 calculations — using the emission factor matching and calculation prompts from Module 4.

4. Document the full workflow for repeatability. Anyone on your team should be able to run the workflow using your documented prompts, review protocols, and quality checks.

Weeks 7-8: Add your second workflow

With supplier data collection running in production, add a second AI-assisted workflow. The recommended second workflow depends on your priorities:

If your primary pressure is regulatory compliance: Add multi-framework mapping and disclosure drafting (Module 5). Use AI to map your data to CSRD/ESRS data points, generate first-draft narratives, and cross-reference against prior-year disclosures.

If your primary pressure is supply chain risk: Add supplier ESG screening and adverse media monitoring (Module 6). Use AI to screen your full supplier base against ESG criteria and set up monitoring for adverse events.

If your primary pressure is emissions accuracy: Add carbon accounting quality assurance. Use AI for year-over-year variance analysis, emission factor validation, and decomposition analysis (Module 4).

Phase 3: Days 61-90 — From periodic to continuous

Phase 3 is where the transformation happens. You move from using AI as a periodic tool (during reporting season) to a continuous capability that keeps your ESG data current year-round.

Weeks 9-10: Establish continuous data ingestion

Instead of collecting all supplier data in a single annual push, set up a rolling collection process:

1. Quarterly data requests to your top 50 suppliers (by emissions materiality), with AI processing responses as they arrive
2. Automated extraction of utility bills and energy data as they are received monthly, feeding directly into your emissions tracking
3. Continuous supply chain monitoring through AI-powered adverse media scanning and certification tracking

This means that when your annual reporting deadline arrives, 60-70% of your data is already collected, processed, and validated. Reporting season becomes a consolidation and review exercise rather than a data collection marathon.

Weeks 11-12: Prepare for the next reporting cycle

Use the remaining time to:

1. Review and refine your prompts. After a full cycle of AI-assisted processing, you will know where your prompts work well and where they need improvement. Document the refinements.

2. Update your emission factor databases. Ensure your AI workflows reference the current year's factors. Set a calendar reminder to update annually.

3. Brief your assurance provider. If your sustainability report will be assured, brief your auditor on the AI-assisted workflows you have implemented. Walk them through the audit trail: source documents, prompts, AI outputs, human reviews. Getting their input now prevents surprises during the assurance engagement.

4. Prepare your expansion plan. Based on Phase 1 and 2 results, identify the next workflows to automate. Present to leadership with updated ROI based on actual (not projected) savings.

Aligning your implementation with regulatory deadlines

Your 30/60/90 day plan should be timed to align with your most pressing regulatory deadline. Here is how to sequence:

If your CSRD report is due in 12+ months: You have time to do this properly. Run the full 30/60/90 plan, then use the remaining months to refine workflows, expand coverage, and prepare for assurance. This is the ideal scenario.

If your CSRD report is due in 6-12 months: Compress the timeline. Run the pilot in 2 weeks instead of 4. Move to production immediately. Focus AI-assisted workflows on the specific ESRS data points where you have the biggest gaps. Prioritise breadth of coverage over depth of automation.

If your CSRD report is due in less than 6 months: Focus exclusively on the workflows that address your most critical gaps. If supplier data collection is incomplete, use AI to process what you have, run gap analysis, and prioritise follow-ups. If narrative drafting is the bottleneck, use AI to generate first drafts of disclosure sections. Do not try to implement everything — focus on what moves the needle most for this reporting cycle, and plan the full implementation for the next cycle.

If you are preparing for SEC Climate Disclosure: Focus your AI implementation on emissions data quality and consistency with financial filings. SEC requirements are more narrowly focused on climate but carry securities law liability. Accuracy and cross-referencing against your 10-K are non-negotiable.

If you are preparing for ISSB/IFRS S2 adoption: Timeline depends on your jurisdiction's adoption schedule. Use the time to build robust climate data workflows (Scopes 1, 2, and 3), scenario analysis capabilities, and risk management disclosures.
