ESRS E1-1 Climate Transition Plan

ZAYAZ Execution & Validation Framework (2026)

---

1. Purpose & Regulatory Positioning

Under ESRS E1-1, undertakings must disclose structured information regarding their climate transition plan, where such a plan exists or is being developed. The objective is to demonstrate alignment with the Paris Agreement (1.5°C pathway) and EU climate neutrality by 2050.

Within ZAYAZ, the Transition Plan is treated as:

• A strategic artifact
• A financial modeling input
• A risk quantification driver
• A taxonomy alignment bridge
• An assurance-relevant evidence object

It is not narrative. It is a structured, validated, computable object.

2. Mandatory Structural Components (Execution Logic)

ZAYAZ validates the Transition Plan across five pillars.

---

Pillar I – Strategic Alignment & Scenario Compatibility

Required Elements

1. Formal alignment statement with:

• Paris Agreement temperature objective (1.5°C)
• EU Climate Neutrality 2050 (where applicable)

2. Decarbonization levers:

• Electrification
• Energy efficiency
• Fuel switching
• Product redesign
• Supply chain decarbonization

3. Scenario resilience analysis:

• At least two forward-looking scenarios
• Transition risk + physical risk differentiation
• Business model viability assessment

Computation Hub Integration

• Scenario inputs feed:
  • Climate VAR modeling
  • Revenue sensitivity stress testing
  • CapEx repricing simulation

---

Pillar II – Targets & Decarbonization Roadmap

Required Elements

• Absolute GHG reduction targets (Scope 1, 2, material Scope 3)
• Base year definition
• Interim milestones (2030 / 2040 / 2050)
• Clear separation of:
  • Gross emissions
  • Removals
  • Avoided emissions

Validation Rules

• Removals cannot offset gross emissions for target accounting.
• Scope coverage must match material value chain emissions.
• Targets must be time-bound and measurable.

Computation Hub Integration

• Trajectory curve modeling
• Target feasibility analysis
• Backcasting alignment engine

---

Pillar III – Financial Linkage (The Critical Gap vs GRI)

This is where most organizations fail ESRS.

Required Disclosures

1. CapEx allocated to decarbonization actions (multi-year)
2. OpEx linked to transition activities
3. EU Taxonomy-aligned percentage of CapEx/OpEx
4. Funding sources:

• Green bonds
• Internal financing
• Subsidies

Required Quantification

• Monetary amounts in EUR
• Multi-year forecast horizon
• Allocation logic per initiative

ZAYAZ Enforcement Logic

If:

transition_plan_exists = true

Then:

capex_alignment_engine = mandatory
taxonomy_alignment_engine = mandatory
financial_quantification_required = true

NOTE: IFRS Treatment of Transition Plan Investments

CapEx allocated to decarbonisation actions must be recognised and measured in accordance with applicable IFRS standards (e.g., IAS 16, IAS 38, IAS 36). Sustainability classification or EU Taxonomy alignment does not modify accounting treatment. Undertakings must ensure that transition plan financial disclosures reconcile to audited financial statements.

ZAYAZ's Decarbonisation Ledger Tagging Protocol (DLTP) allowes tagged projects and transactions in accounting systems (e.g. ZYZ-DECARB), to automatically be extracted by our accounting crawler and populate transition plan CapEx fields.

See the separate documentation for more information on DLTP.

Pillar IV – Asset-Level Risk & Locked-In Emissions

Required Analysis

• Identification of high-emission assets
• Stranded asset exposure risk
• Locked-in emissions from existing infrastructure

Quantitative Component

• Estimated cumulative emissions from legacy assets
• Early retirement cost estimates
• Sensitivity under carbon pricing scenarios

Computation Hub Modules

• Stranded Asset Risk Model
• Carbon Price Stress Model
• Asset Depreciation Risk Simulator

---

Pillar V – Governance & Just Transition

Required Disclosures

• Board approval and oversight
• Monitoring frequency
• Executive remuneration linkage
• Just Transition considerations:
• Workforce reskilling
• Regional impacts
• Social mitigation measures

Validation Logic

If:

board_approval = false

Then:

governance_risk_flag = high
assurance_readiness_score = reduced

---

3. Digital & Assurance Requirements

Under CSRD:

• Sustainability statement must be XHTML
• Tagged with XBRL taxonomy
• Subject to limited assurance

ZAYAZ enforces:

• Tag completeness validation
• Cross-check between:
  • Emissions trajectory
  • Financial allocation
  • CapEx taxonomy eligibility
