What is ESG? A Complete Guide for Finance and Accounting Professionals
ESG explained for finance and accounting professionals: what Environmental, Social and Governance means, why it matters, how it's measured, and its growing role in investment and corporate reporting.
What is ESG?
ESG stands for Environmental, Social, and Governance — three broad criteria used to assess how a company manages its impact on the world and how well-governed it is. Originally used by institutional investors to screen investments, ESG has expanded into a core framework for corporate reporting, risk management, and strategic decision-making.
For finance and accounting professionals, ESG is no longer a niche concept — it is rapidly becoming a mainstream part of the profession, embedded in financial reporting standards, regulatory requirements, and investor expectations globally.
The Three Pillars of ESG
Environmental (E)
How a company manages its environmental footprint:
- Carbon emissions and climate change strategy
- Energy efficiency and renewable energy usage
- Water usage and waste management
- Biodiversity and land use
- Supply chain environmental impact
Social (S)
How a company manages relationships with stakeholders:
- Labour practices, employee wellbeing, health and safety
- Diversity, equity and inclusion (DEI)
- Human rights in supply chains
- Community engagement and social impact
- Data privacy and customer protection
Governance (G)
How a company is led and held accountable:
- Board composition, independence, and diversity
- Executive pay and alignment with shareholder interests
- Audit quality and financial transparency
- Anti-corruption and bribery policies
- Shareholder rights and stakeholder engagement
Why ESG Matters in Finance and Accounting
ESG has moved from voluntary reporting to mainstream finance:
- Regulatory pressure: The EU's CSRD, SEC climate disclosure rules, and India's BRSR are making ESG reporting mandatory for large companies
- Investor demand: Over $30 trillion is now invested using ESG criteria globally
- ISSB standards: IFRS S1 and IFRS S2 published in 2023 establish global baseline sustainability disclosure standards
- Risk management: Climate risk, social risk, and governance failures are increasingly recognised as material financial risks
ESG Ratings and Scores
ESG rating agencies assess companies and assign ESG scores:
- MSCI ESG Ratings: AAA (best) to CCC (worst)
- Sustainalytics: Risk score from 0 (negligible) to 40+ (severe)
- S&P Global ESG Scores: 0–100 scale
- CDP: Focuses on climate, water, and forests disclosure
ESG and the Accounting Profession
Accountants are at the centre of ESG implementation — preparing sustainability reports, providing assurance over ESG data, and integrating financial and non-financial performance.
