Consultation Response by ESG Book to UK Sustainability Reporting Standards & Transition Plan Requirements

Supporting ESG Transparency and Transition Planning Across the UK’s ESG Landscape
September 24, 2025

The UK’s twin consultations on UK Sustainability Reporting Standards (UK SRS) and the government’s Transition Plan requirements show how the country is shaping a next-generation ESG disclosure regime. While both aim to drive transparent, decision-useful reporting, they differ in focus: UK SRS sets the baseline for sustainability disclosure across all sectors, whereas the Transition Plan consultation hones in on credible net-zero strategies.

1. UK SRS

A Principles-Based Baseline for Sustainability Reporting

Key Takeaways & Supportive Points

  • Timely, integrated disclosure: Backing the removal of a one-year “transition relief,” respondents stressed that UK firms are already familiar with TCFD reporting and can integrate sustainability data with financial statements without delay.
  • Flexibility where it matters: Support emerged for removing mandatory references to specific taxonomies (e.g., GICS, SASB), promoting a principles-based approach while maintaining international alignment with ISSB standards.
  • Investor relevance: Agreed that transparent reporting on financed emissions, carbon credit use, and broader ESG risks (biodiversity, water, supply chains) improves capital allocation and market confidence.

Areas of Concern & Recommendations

  • Scope 3 and financed emissions: Data gaps and comparability issues remain. The government should provide stronger guidance, sector-specific methodologies (e.g., PCAF, GFANZ), and digital data platforms to simplify data collection.
  • Scenario analysis complexity: Preparers need practical, UK-specific tools and templates for applying climate scenarios and reconciling them with financial statements.
  • SME readiness: Training, grants, and simplified reporting templates will be essential to avoid leaving smaller firms behind.

2. Transition Plan Requirements

Making Net-Zero Strategy Credible

Key Takeaways & Supportive Points

  • Strategic value creation: Transition planning is more than compliance - it drives competitiveness, attracts capital, and lowers financing and insurance costs.
  • Investor and market demand: Standardised transition disclosures help investors price risk, channel capital, and guard against greenwashing.
  • Broader economic benefit: Aggregated transition plans can guide national infrastructure investments, support job creation, and enhance macroeconomic resilience.

Areas of Concern & Recommendations

  • Cost and capacity hurdles: Robust plans require extensive data (including Scope 3), scenario modelling, and capital-expenditure mapping - challenging for SMEs and hard-to-abate sectors.
  • Comparability gaps: Without a mandatory template or minimum disclosure requirements, plans may lack consistency.
  • Balance between ambition and liability: Mandating implementation or strict net-zero alignment creates legal and operational risks if external enablers (grid capacity, technology rollout) lag.

Suggested Enhancements

  • Introduce a structured transition-plan annex covering targets, CapEx, financing, and governance.
  • Strengthen Scope 3 and supplier-engagement disclosures.
  • Provide standard scenario baselines for comparability and phased assurance for key metrics.
  • For adaptation, require reporting on asset-level exposures, costs, and contingency triggers to capture climate-resilience planning.

Closing Thought

At ESG Book, we view the UK’s focus on robust sustainability reporting (UK SRS) and credible transition planning as a natural progression of global ESG disclosure and a constructive step for businesses seeking stronger strategies and improved access to capital. By coupling rigorous, ISSB-aligned reporting with finance-ready transition plans, the UK is setting a high standard for transparent and forward-looking sustainability practices. Companies that integrate these requirements into their strategy, finance, and supply chains can enhance resilience and competitiveness while meeting evolving regulatory expectations.
