A company spills oil in a river community. It pays a fine, loses its licence to a competitor and sees its shares fall, and its bank asks for a climate plan before the next loan. Another company in the same industry spends on a clean-up fund, a community trust and an audited emissions report, and gets cheaper funding.
Environmental, social and governance (ESG) matters are no longer a side issue for oil, gas and mining companies. They decide licences, finance, reputation and, through the deductions and levies you have just studied, tax.
This topic covers the background to ESG, the regulators, the need for ESG, the compliance duties in the environmental, social and governance areas, the benefits and challenges of sustainable practices and how to meet them, the best practices, the history of ESG, the sustainability reporting standards of the International Sustainability Standards Board (ISSB), penalties for non-compliance and the standards of the Extractive Industries Transparency Initiative (EITI).
It is the last topic of the syllabus. The previous topic covered mining tax, royalties and the NEITI Act.
In 30 seconds
ESG means environmental (pollution, waste, biodiversity, climate), social (communities, human rights, benefit sharing) and governance (transparency, anti-corruption, board oversight) duties. Regulators: NESREA (environment), the NUPRC and NMDPRA (oil and gas), NEITI (transparency). Reporting: the ISSB issued IFRS S1 (sustainability-related financial information) and IFRS S2 (climate disclosures) in 2023; Nigeria adopted them in 2023, with voluntary use to 2027 and mandatory reporting for public interest entities from 1 January 2028, and small and medium entities from 2030.
Law: the Climate Change Act 2021 (net zero between 2050 and 2070, carbon budgets, a climate change officer in entities with 50 or more employees). EITI: the 2023 Standard requires disclosure of revenues, contracts, beneficial owners, production and social spending. Tax link: host community trust, decommissioning and rehabilitation contributions are deductible, subject to conditions; gas flare penalties are not.

The rules in more depth
Background and the need for ESG
ESG has grown because of concern about climate change, pollution and depletion of resources; labour abuse, human rights and displacement of communities; and corporate scandals that showed the cost of poor governance. The need for ESG rests on five points:
- Risk management: identifying and managing environmental, social and governance risks.
- Long-term sustainability: resilience and survival over time.
- Stakeholder expectations: investors, customers, employees and communities expect responsible behaviour.
- Regulatory requirements: governments are making ESG laws, so compliance is essential.
- Reputation and brand value: good practice builds them, poor practice damages them and costs money.
Regulators: the National Environmental Standards and Regulations Enforcement Agency (NESREA) enforces environmental regulations; the Nigerian Upstream Petroleum Regulatory Commission and the Nigerian Midstream and Downstream Petroleum Regulatory Authority regulate the oil and gas industry (the Department of Petroleum Resources is the old regulator they replaced); and NEITI promotes transparency and accountability.
Relevance: the three areas of compliance
| Area | What companies must do |
|---|---|
| Environmental | Follow the Environmental Impact Assessment Act, the NESREA Act and the Petroleum Industry Act; carry out environmental impact assessments and plan to reduce risks; dispose of waste, including hazardous waste, properly; have oil spill response plans; protect biodiversity; control pollution; cut greenhouse gas emissions; manage waste |
| Social | Engage with local communities and respect their rights; respect human rights, including those of indigenous and vulnerable groups; restore livelihoods affected by operations, with fair compensation; invest in education, health and infrastructure; protect cultural heritage; carry out social impact assessments; share benefits with communities |
| Governance | Be transparent in operations, reporting and decisions; prevent corruption and bribery; comply with laws and standards; engage stakeholders including government, civil society and communities; keep effective board oversight of ESG |
Challenges and opportunities in the extractive industry
- Challenges: environmental degradation (pollution and habitat loss); social conflict over land and benefit sharing; corruption; lack of transparency; weak enforcement; unclear and changing regulation.
- Opportunities: sustainable development; economic growth; jobs and local economies; better governance and accountability from strong ESG practice.
Benefits and challenges of sustainable practices for companies
| Benefits | Challenges |
|---|---|
| Better reputation, attracting customers and investors | High start-up cost for technology, infrastructure and training |
| Cost savings from energy efficiency, waste reduction and resource conservation | Complex supply chains with many tiers of suppliers |
| Innovation in products, services and business models | Different rules and standards in different regions |
| Lower risk of regulatory, supply and reputational problems | Getting investors, customers, staff and regulators to agree |
| Easier access to capital as investors weigh ESG factors | Measuring and reporting impact accurately needs good data |
| Attracting and keeping talent, and better motivation | Balancing short-term profit and long-term goals |
| Protection against greenwashing, because real steps can be reported | In Nigeria: unpredictable regulation, limited awareness, financial constraints, weak infrastructure such as power and transport, and varied practice across industries |
How to meet the challenges:
- a clear sustainability strategy tied to business goals
- engagement with stakeholders
- investment in technology
- partnership with suppliers, peers and non-governmental organisations
- regular monitoring and reporting
Banking and oil and gas companies report most; larger, more profitable companies and those audited by the largest audit firms are more likely to adopt sustainability reporting.
Benefits of ESG compliance
- Improved reputation and trust, and more goodwill and brand value.
- More investment and funding.
- Less risk, and fewer costly fines and penalties from regulators.
- Sustainable development and better well-being for communities.
- Better financial performance over the long term.
- A smaller environmental footprint, social responsibility and good governance.
Best practices
- Adopt international standards such as the EITI Standard, the International Finance Corporation Performance Standards and the United Nations Guiding Principles on Business and Human Rights.
- Engage stakeholders regularly.
- Build capacity in companies and government agencies.
- Publish regular reports on ESG performance and disclose operations, finances and sustainability initiatives.
History of ESG
| Date | Event |
|---|---|
| 1962 | Rachel Carson’s Silent Spring starts the environmental movement |
| 1971 | Pax World Funds, the first US mutual fund to weigh social and environmental factors (socially responsible investing) |
| 1987 | Brundtland Commission defines sustainable development |
| 1992 | Rio Earth Summit; UNEP statement of commitment by financial institutions |
| 1994 | John Elkington introduces the triple bottom line |
| 1997 | Global Reporting Initiative founded |
| 2004 | “Who Cares Wins” report from the UN Global Compact coins the term ESG |
| 2006 | Principles for Responsible Investment launched |
| 2010s | Standardisation of reporting; the Sustainability Accounting Standards Board issues industry-specific standards |
| 2023 | ISSB issues IFRS S1 and IFRS S2 |
IFRS S1 requires an entity to disclose information on its sustainability-related risks and opportunities that is useful to users of general purpose reports and material to its cash flows, access to finance and long-term viability. IFRS S2 requires disclosure of climate-related risks and opportunities, for decisions on resource allocation and access to capital.
Because oil, gas and mining companies have a large effect on the environment and climate, stakeholders expect them to follow these standards.
In Nigeria. The Financial Reporting Council adopted the standards in 2023 and published a roadmap:
- voluntary adoption from 2024 to 2027
- mandatory reporting for public interest entities from 1 January 2028
- small and medium entities from 2030
Entities are asked to give the Council a board resolution to adopt the standards, a gap analysis against S1 and S2 and an implementation plan.
The Climate Change Act 2021, signed on 18 November 2021, sets a net zero emissions target between 2050 and 2070, requires carbon budgets and an action plan under the National Council on Climate Change, and requires entities with at least 50 employees to designate a climate change or environmental sustainability officer who reports each year on emission reduction.
Penalties for non-compliance
| Type | Examples |
|---|---|
| Financial | Fines, which vary with the size and type of company; fines under the Climate Change Act and under data protection law when ESG data is mishandled; in some countries, securities regulators fine firms for misleading ESG disclosure |
| Legal | Litigation and settlements; audits and investigations that disrupt operations; loss of an operating licence in severe cases |
| Reputational | Loss of trust of investors and customers; bad publicity; a competitive disadvantage against compliant firms |
| Operational | Inefficiency and less innovation; supply chain disruption when suppliers are not compliant; fewer future business opportunities, because governments and large buyers require ESG compliance |
The EITI Standard
The Extractive Industries Transparency Initiative Standard is the global benchmark for transparency and accountability in oil, gas and mining. Its parts are:
- Principles: the shared commitments of all stakeholders to transparency, accountability and good governance.
- Disclosure requirements along the value chain: revenue collection; revenue allocation to government bodies and projects; contracts, licences and beneficial ownership; production; social and economic spending, including quasi-fiscal spending; state-owned enterprises; commodity trading; and an open data policy.
- Governance and oversight: clear roles for multi-stakeholder groups, boards and secretariats.
- Validation: regular assessment of whether countries meet the requirements.
The 2023 Standard adds attention to the energy transition, corruption risks, gender equity and inclusion, and stronger revenue collection and management.
Where ESG meets tax
| ESG cost or duty | Tax treatment |
|---|---|
| Host community development trust contribution (3% of operating spend) | Deductible; outside the cost price ratio |
| Decommissioning and abandonment fund | Deductible if 30% of the fund is deposited in a Nigerian bank (for converted leases) |
| Mine rehabilitation and closure fund | Deductible if cash-backed and held by independent trustees |
| Environmental remediation fund and NDDC charge | Deductible for hydrocarbon tax and outside the cost price ratio |
| Gas flare fees and penalties | Not deductible |
| Development levy (4%) | Replaces the education and other levies; not charged on hydrocarbon tax profit |
Worked examples
Example 1: which pillar? (a) A company runs an oil spill response drill. (b) A company shares a community survey on land and pays compensation for lost farms. (c) A company adopts an anti-bribery policy and reports to its board each quarter.
- (a) Environmental: spill response and pollution control.
- (b) Social: community engagement and livelihood restoration.
- (c) Governance: corruption prevention and board oversight.
Example 2: the reporting timetable. A listed oil company asks when it must report under IFRS S1 and S2.
- It is a public interest entity, so reporting is mandatory from 1 January 2028.
- Until 2027, adoption is voluntary, but it should file a board resolution, a gap analysis and an implementation plan.
- Small and medium entities follow from 2030.
Example 3: the climate officer. A company has 120 employees and no one is responsible for climate matters.
- The Climate Change Act requires entities with at least 50 employees to designate a climate change or environmental sustainability officer.
- The officer reports yearly on progress in cutting emissions to the National Council’s secretariat.
Example 4: tax on ESG spending. A lessee pays ₦120m to a host community trust, ₦200m into a decommissioning fund (with 30% of the fund in escrow) and ₦40m as a gas flare fee.
- The trust contribution of ₦120m is deductible and outside the cost price ratio.
- The decommissioning contribution of ₦200m is deductible because the escrow condition is met.
- The ₦40m flare fee is a penalty and is not deductible.
How to score full marks
- Name the three pillars and give two or three specific points under each.
- Link a point to the industry: spills, community land, board oversight.
