Sustainability Reporting and Measurement for ACCA Business and Technology

Updated 11 October 2026 · Fact-checked

Sustainability reporting is how an organisation measures and discloses its environmental, social and governance (ESG) performance. Frameworks include integrated reporting, which links six capitals to value creation, and the ISSB standards IFRS S1 and S2. Carbon footprint measures count greenhouse gas emissions. To answer questions, identify the framework, then match it to its purpose and user.

Understand Sustainability Reporting and Measurement

Sustainability reporting means measuring and disclosing how a business affects the environment and society, and how those issues affect the business. Traditional financial statements show profit and financial position. They say little about emissions, workforce, or ethics. Sustainability reports fill that gap.

ESG is a way of grouping the issues. Environmental covers emissions, energy, water and waste. Social covers employees, health and safety, communities and supply chains. Governance covers board structure, pay, ethics and controls. ESG is often used by investors to judge risk. CSR (corporate social responsibility) is a broader idea of a company's duty to society. CSR is about the company's own approach and commitments, often voluntary. ESG is about measurable factors that can be reported and compared.

Integrated reporting (the <IR> Framework) presents a single report showing how strategy, governance, performance and prospects create value over time. It uses six capitals: financial, manufactured, intellectual, human, social and relationship, and natural. The aim is integrated thinking, so that the business sees how its use of these capitals links together. The main audience is providers of financial capital.

ISSB is the International Sustainability Standards Board, set up by the IFRS Foundation. IFRS S1 sets general requirements for disclosing sustainability-related risks and opportunities that could affect the entity's prospects. IFRS S2 covers climate-related disclosures. The focus is information useful to investors and lenders, so it is built around the idea of what is material to them.

Carbon footprint is the total greenhouse gas emissions caused by an organisation, usually in tonnes of carbon dioxide equivalent (CO2e). The Greenhouse Gas Protocol splits emissions into three scopes. Scope 1 is direct emissions from sources the entity owns or controls. Scope 2 is indirect emissions from purchased electricity, heat or steam. Scope 3 is all other indirect emissions in the value chain, such as suppliers, business travel and use of products sold.

Key formulas to remember

Carbon footprint (basic calculation)
Emissions (tonnes CO2e) = Activity data × Emission factor
Activity data is the amount of fuel, electricity or distance used. The emission factor converts it to CO2e. Use the factor given in the question.
Six capitals of integrated reporting
Financial, Manufactured, Intellectual, Human, Social and relationship, Natural
Learn all six. Questions often ask you to match an example to a capital.
Greenhouse gas scopes
Scope 1 = direct; Scope 2 = purchased energy; Scope 3 = other value-chain emissions
Scope 3 is usually the largest and hardest to measure.
ESG components
E = Environmental; S = Social; G = Governance
Place each example in the correct letter.

How to solve Sustainability Reporting and Measurement questions

Use this method for any question on measuring or reporting sustainability performance.

  1. 1Read the question and decide what is being asked: a definition, a framework, a measure, or a calculation.
  2. 2Identify the framework or term: ESG, CSR, integrated reporting, ISSB (S1 or S2), or carbon scopes.
  3. 3Recall its purpose and main audience. ISSB and integrated reporting focus on investors. CSR is wider.
  4. 4For a classification question, match the example to the category: E, S or G; one of the six capitals; or scope 1, 2 or 3.
  5. 5For a calculation, multiply activity data by the emission factor and check the units.
  6. 6Check the wording for traps such as voluntary versus mandatory, or direct versus indirect.
  7. 7For multiple response, select exactly the number asked for.

Quickest way: Keyword matching

When to use it: Use this for Section A objective questions when time is short.

  1. Spot the key term: climate points to IFRS S2, general sustainability risks point to IFRS S1.
  2. Six capitals or value creation points to integrated reporting.
  3. Own vehicles or boilers is scope 1. Purchased electricity is scope 2. Suppliers, travel and product use is scope 3.
  4. Staff, safety and communities is social. Board and ethics is governance. Emissions and waste is environmental.
  5. Eliminate options that do not fit, then choose.

Common mistakes in Sustainability Reporting and Measurement

  • Treating ESG and CSR as identical.

    Both deal with responsible business, so they sound alike.

    Fix: Say ESG is a set of measurable factors investors assess. CSR is the broader idea of a company's responsibility to society.

  • Putting purchased electricity in scope 1.

    Students think any energy use is direct.

    Fix: The emissions occur at the power station, not at your site. Purchased energy is scope 2.

  • Saying IFRS S2 covers all sustainability topics.

    Students mix up S1 and S2.

    Fix: S1 is the general requirements. S2 is climate-related disclosures.

  • Listing only four or five capitals in integrated reporting.

    The names are similar and easy to merge.

    Fix: Learn the six: financial, manufactured, intellectual, human, social and relationship, natural.

  • Forgetting the emission factor or mixing units in a calculation.

    Students rush and multiply the wrong figures.

    Fix: Write the formula, label each figure with its unit, and check the answer is in tonnes CO2e or the unit asked.

Worked examples

Example 1

A manufacturer's report shows: (1) fuel burned in its own delivery trucks, (2) electricity bought from the grid, (3) emissions from its suppliers' factories. Classify each by greenhouse gas scope.

Show the solution
  1. Own trucks are owned or controlled by the entity, so emissions are direct: scope 1.
  2. Purchased electricity is an indirect emission from purchased energy: scope 2.
  3. Suppliers' factories are other indirect emissions in the value chain: scope 3.

Answer: (1) Scope 1, (2) Scope 2, (3) Scope 3.

Example 2

A company uses 40,000 litres of diesel in a year. The emission factor is 2.7 kg CO2e per litre. Calculate its emissions in tonnes of CO2e.

Show the solution
  1. Emissions = activity data × emission factor.
  2. 40,000 × 2.7 = 108,000 kg CO2e.
  3. Convert to tonnes: 108,000 ÷ 1,000 = 108.

Answer: 108 tonnes CO2e.

Exam tips

  • Learn the six capitals and be able to match an example, such as staff training, to the right one.
  • Know which ISSB standard covers what: S1 general, S2 climate.
  • For scope questions, ask who owns the source and who generates the emissions.
  • In ESG versus CSR questions, look for the words measurable and investor-focused (ESG) or wider responsibility (CSR).
  • In number entry questions, check the units and round only as instructed.

Sustainability Reporting and Measurement: frequently asked questions

What is the difference between ESG and CSR?

ESG is a set of environmental, social and governance factors that can be measured and reported, often used by investors. CSR is the broader idea that a business has responsibilities to society. CSR describes the approach, while ESG gives measures.

What are IFRS S1 and IFRS S2?

They are standards from the ISSB. IFRS S1 sets general requirements for disclosing sustainability-related risks and opportunities. IFRS S2 sets requirements for climate-related disclosures.

What is integrated reporting?

It is a report that explains how an organisation creates value over time. It uses six capitals and shows how strategy, governance and performance link together. It aims to promote integrated thinking.

How do you measure a business's carbon footprint?

You collect activity data, such as fuel and electricity used, and multiply it by emission factors to get tonnes of CO2e. You then group emissions into scopes 1, 2 and 3.
