How to write a sustainability report

Sustainability and ESG reporting has evolved from a nice-to-have into a crucial component of corporate communications. Companies face mounting pressure to demonstrate their commitment to environmental and social responsibility, driven by regulatory requirements, investor expectations and growing public awareness of sustainability issues.

The business case for comprehensive sustainability reporting is compelling. Beyond regulatory compliance, robust reporting can enhance brand reputation, attract environmentally conscious customers and investors, and demonstrate corporate citizenship. Moreover, research consistently shows a strong correlation between sustainability performance and financial success, with investors increasingly incorporating ESG criteria into their decision-making processes.   

ESG vs Sustainability Reporting

While often used interchangeably, ESG and sustainability reporting have distinct characteristics that are worthwhile understanding.

ESG reporting follows specific frameworks and metrics, focusing on environmental, social and governance performance indicators. These reports typically adhere to established standards such as the Global Reporting Initiative (GRI) or Sustainability Accounting Standards Board (SASB) frameworks.

Sustainability reporting, in contrast, often takes a broader and more holistic approach. While it may incorporate ESG elements, sustainability reports can encompass additional aspects such as economic impact, community engagement and long-term business sustainability. This flexibility allows organisations to tell their sustainability story in a way that best reflects their values and initiatives.

Both types of reporting serve valuable purposes. ESG reports provide standardised, comparable data that investors and regulators require, while sustainability reports offer a platform for organisations to communicate their broader impact and commitments to various stakeholders.

Key components of a sustainability report

Before looking at the writing process, it’s important to consider the fundamental elements that make up a comprehensive sustainability report. While the exact structure may vary based on your organisation’s needs and chosen framework, there are certain components which are typically present.  

Reporting frameworks and standards

Several established frameworks guide sustainability reporting, each with distinct focuses and requirements.

The Global Reporting Initiative (GRI) Standards represent the most comprehensive and widely used framework, suitable for organisations of all sizes and sectors. The Sustainability Accounting Standards Board (SASB) focuses on financially material sustainability information for investors, while the Task Force on Climate-related Financial Disclosures (TCFD) specifically addresses climate-related risks and opportunities. Many organisations also align their reporting with the UN Sustainable Development Goals (SDGs), providing a framework for connecting sustainability efforts with global objectives.

There are many options – however, it is commonplace for organisations to align with multiple frameworks and select the most relevant aspects of each to tell their sustainability story effectively. 

Sustainability report template

Indeed, there is no one size fits all formula for ESG and sustainability reports, as this will largely depend on the type of organisation and the stories to be told.

However, a well-structured sustainability report could include the follow sections:

  • GRI/framework index: Cross-reference to relevant reporting standards.
  • Executive statement: A message from leadership demonstrating commitment to sustainability.
  • Organisational overview: Company profile, values, and sustainability strategy.
  • Materiality assessment: Key issues identified as most important to stakeholders.
  • Environmental performance: Emissions, energy, waste, and other environmental metrics.
  • Social impact: Employee wellbeing, diversity, community engagement, and human rights.
  • Governance: Ethical practices, risk management, and corporate governance.
  • Economic value: Business performance and economic contribution.
  • Goals and targets: Future commitments and progress against existing targets.
  • Methodology: Data collection approaches and calculation methods.

What does the sustainability report writing process look like?

Creating an effective sustainability report requires careful planning and systematic execution. The process typically involves several key stages that ensure comprehensive coverage and accurate representation of your organisation’s sustainability efforts.  

Data collection and analysis

The foundation of any credible sustainability report is robust data. Begin by identifying key performance indicators (KPIs) that align with your sustainability objectives. These might include environmental metrics such as carbon emissions, energy consumption and waste management; social indicators including workforce diversity, employee wellbeing and community impact; governance measures such as board composition, ethical practices and risk management; and economic factors demonstrating the business case for sustainability initiatives.

Establish systems for collecting and verifying this data to ensure accuracy and consistency across reporting periods. Although this will not fall under the remit of a sustainability report writer, they will need access to data and evidence in order to produce a compelling narrative

Setting objectives and benchmarks

Clear objectives and measurable targets are essential for meaningful sustainability reporting. Define specific, time-bound goals that demonstrate your commitment to improvement. These might include emissions reduction targets, diversity goals or community investment benchmarks.

Compare your performance against industry standards and best practices. This context helps stakeholders understand your progress and ambitions within the broader sustainability landscape. 

Production approach

The approach to producing your sustainability report can vary depending on your resources and expertise. Similar to white paper writing, success depends on thorough planning and clear objectives. Consider whether to handle the process in-house or engage external sustainability report writing expertise.

Regardless of approach, establish a clear timeline and allocate responsibilities early. Ensure key stakeholders are engaged throughout the process and build in adequate time for data verification and content review.

Top tips on how to write a sustainability report

Content and structure

A strong sustainability report begins with a clear executive summary highlighting key achievements and challenges. Structure your report logically – this could follow established frameworks like GRI Standards or the UN Sustainable Development Goals.

The most effective reports combine quantitative and qualitative information – while data demonstrates performance, case studies and narrative elements help bring your sustainability initiatives to life. Consider incorporating stakeholder testimonials and real-world examples of your sustainability efforts in action to add depth and credibility to your reporting.

Stakeholder engagement

Effective stakeholder engagement should thread throughout your entire reporting process.

This could begin with comprehensive materiality assessments to identify the issues that matter most to your various stakeholder groups. Meanwhile, it is worth gathering and incorporate feedback from previous reports to ensure continuous improvement in your reporting approach.

Throughout your report, weave in stakeholder voices through carefully chosen quotes and case studies that illustrate the real-world impact of your initiatives. Transparency in addressing stakeholder concerns builds trust and credibility, while maintaining regular engagement beyond the reporting cycle helps ensure your sustainability reporting remains relevant and responsive to stakeholder needs.

Data visualisation

Good sustainability reports transform complex data into clear, engaging visual presentations. When creating charts and graphics, choose formats that best suit your data type – line graphs for trends, bar charts for comparisons, and infographics for complex processes or relationships.

Maintain consistent styling throughout your report, including thoughtful colour schemes that ensure accessibility. Every visual element should include clear labels and explanations that help readers understand the significance of the data presented. Whenever possible, show trends over time to demonstrate progress and commitment to long-term goals.

Future commitments and goals

Setting and communicating meaningful targets forms a crucial part of sustainability reporting. Your report should outline both short and long-term goals, ideally aligned with recognised frameworks such as Science Based Targets.

It is also important to provide clear timeframes and milestones for achieving these objectives, along with detailed explanations of how progress will be measured. Honest reporting of progress against previous targets builds credibility, while a combination of qualitative and quantitative objectives helps paint a complete picture of your sustainability ambitions.

Common pitfalls to avoid

  • Overwhelming readers with too much data
  • Making claims without evidence
  • Focusing solely on positive achievements
  • Using inconsistent metrics across reports
  • Neglecting to explain methodology
  • Missing sector-specific context
  • Failing to link initiatives to business strategy

Do you need to onboard sustainability copywriting expertise?

While many organisations handle sustainability reporting in-house, there are compelling reasons to consider external expertise. Internal teams often have deep knowledge of sustainability initiatives but may lack experience in crafting engaging narratives or structuring complex reports.

Professional sustainability copywriters bring valuable perspectives and skills to the process. They can translate technical information into accessible content, ensure consistency in tone and messaging, and bring best practice insights from other organisations and sectors. External ESG report writers can also free up internal resources for data collection and verification, which will help you to meet tight deadlines.

The investment in professional writing support often pays dividends through improved report quality and efficiency. A sustainability copywriter can help ensure your ESG story resonates with target audiences while meeting reporting requirements.
