- Financial Regulators Set New Rules for Climate and ESG Risks
Ghana has unveiled a Sustainable Finance Roadmap intended to move climate and environmental considerations from the margins of financial policy into the everyday decisions of banks, insurers, pension funds and capital-market institutions.
The document establishes a common regulatory direction for a financial system holding GH¢647.25 billion in assets at the end of 2025, equivalent to 45.1 per cent of gross domestic product. Its central proposition is that climate change is no longer simply an environmental matter: it is a source of credit, market, operational, insurance and systemic financial risk.
The banking industry controls 75.6 per cent of financial-sector assets, followed by pensions with 16.8 per cent, securities with 4.2 per cent and insurance with 3.4 per cent. This concentration gives banks particular influence over whether capital continues financing vulnerable and carbon-intensive activities or shifts towards more resilient development.
The roadmap was developed under the leadership of the Bank of Ghana in collaboration with the Securities and Exchange Commission, National Insurance Commission and National Pensions Regulatory Authority. The Ministry of Finance, Institute of Chartered Accountants, Ghana, and Chartered Institute of Bankers contributed, while the International Finance Corporation facilitated the process with international support.
Its stated goal is to provide a “credible, predictable and stable regulatory framework” that prepares the market for sustainable finance while safeguarding financial stability. That formulation is important because it places climate policy within the regulators’ traditional mandate of protecting institutions, customers and the wider economy.
Ghana’s exposure is already visible. Flooding damages property and interrupts businesses; drought and erratic rainfall weaken agricultural production; coastal erosion threatens infrastructure; and rising temperatures and water stress affect companies’ operating costs and borrowers’ repayment capacity.
The roadmap argues that these shocks can travel through an interconnected financial system. Banks have substantial exposure to the securities industry, while pension funds, insurers and investment managers hold many of the same instruments. A climate-related loss that begins in one sector can consequently spread through portfolios, balance sheets and household savings.
This makes coordination necessary. Ghana’s four financial regulators have different statutory mandates and oversee institutions with different business models, but climate and sustainability risks do not respect regulatory boundaries. A bank may finance an exposed company, an insurer may underwrite its assets, and pension funds may own its securities.
The roadmap is organised around three pillars: environmental, social and governance integration; climate and nature-related risk management; and financing sustainability.
The first pillar requires regulated institutions to incorporate ESG considerations into governance, strategy, due diligence, risk management and reporting. Boards will be expected to oversee sustainability and climate risks, establish appropriate committees and ensure that institutions have adequately staffed ESG functions.
Within the first 24 months, regulators are expected to issue minimum guidelines, standard policy templates and reporting requirements. Institutions should complete ESG materiality assessments, apply screening tools to clients and projects, document mitigation measures and align disclosures progressively with IFRS S1 and S2.
This could significantly change credit decisions. Environmental damage, labour practices, community relations, governance weaknesses and reputational exposure would become part of the assessment of whether a borrower or investment presents acceptable risk.
The policy is not intended to apply identical requirements to every institution. Proportionality and materiality are recurring principles. A large bank financing mining, agriculture and energy projects will face different risks from a small institution with limited geographic exposure.
That flexibility is sensible, but it could become a weakness if proportionality is used to justify indefinite delay. Regulators will need clear minimum standards so that smaller institutions receive simplified requirements without being exempted from risks that can still threaten their customers and solvency.
The second pillar treats climate and nature-related risks as financial risks requiring board accountability, management ownership and supervisory attention. Institutions will be expected to identify physical, transition and liability risks and map exposures by sector, geography and product.
Physical risks include floods, storms, heatwaves and wildfires, alongside longer-term threats such as drought, sea-level rise and coastal degradation. Transition risks arise from policy changes, new technology, market preferences and the global movement towards lower-carbon production.
Liability risks could emerge through litigation, environmental claims, failures of fiduciary duty or misleading sustainability disclosures. This creates direct consequences for institutions that market products as green without evidence or fail to assess environmental damage connected to financed activities.
Large and complex institutions will initially conduct qualitative climate scenario analysis before moving gradually towards quantitative stress testing as data and capacity improve. Regulators also plan an ESG data hub and harmonised reporting of sectoral exposure and assets located in flood-prone areas.
The roadmap proposes monthly reporting of core environmental and operational indicators, quarterly reporting of climate exposures and governance metrics, and annual comprehensive sustainability reports. Risk and compliance functions should validate submissions, while external assurance may be required for selected disclosures.
This data programme will be difficult. Many companies lack reliable emissions, energy-use and supply-chain information, while financial institutions may struggle to connect customer data with geographic and climate-risk models. Poor information could produce false precision rather than better decisions.
Implementation must therefore prioritise comparable definitions, practical templates and staff training. Technology, including regulatory and supervisory platforms and artificial intelligence, could improve collection and analysis, but automation cannot compensate for inaccurate information supplied at source.
The third pillar moves beyond managing risk to mobilising capital. It identifies climate-resilient infrastructure, climate-smart agriculture, renewable energy, affordable housing, micro, small and medium enterprises and essential social services as priority areas for sustainable finance.
This is where the roadmap’s economic ambition becomes most significant. Ghana’s updated nationally determined contribution contains 47 programmes of action: 34 mitigation programmes and 13 adaptation measures. The mitigation actions are expected to reduce emissions by 64 million tonnes of carbon-dioxide equivalent by 2030 against the business-as-usual trajectory.
Implementing the programme is estimated to cost between US$9.3 billion and US$16 billion, with private capital and international support expected to finance more than 70 per cent. Ghana’s constrained public finances make banks, pension funds, insurers and capital markets essential to closing that gap.
The strategy builds on emerging evidence that climate finance can attract substantial capital. By December 2024, six projects under Ghana’s bilateral carbon-market agreement with Switzerland had reached investment decisions worth more than US$850 million, including government fees, service charges and direct project investment.
The roadmap also cites the World Bank’s US$200 million Clean Cooking Outcome Bond, which matures in March 2032. Part of the coupon otherwise payable to investors is being front-loaded to support the distribution of more than 400,000 cleaner cookstoves, intended to benefit over one million people.
These examples show that innovative finance can connect investor returns with measurable development outcomes. They also demonstrate why credible verification matters: capital will be easier to mobilise when investors can trace proceeds, measure results and compare performance against transparent national standards.
The implications extend beyond specialised green products. Climate analysis could influence ordinary business loans, insurance premiums, pension allocations and securities valuations. Companies with credible transition plans may gain financing advantages, while firms unable to explain environmental exposures could face higher costs or restricted access to capital. That shift makes sustainability a commercial issue for every board.
The roadmap encourages green and social loans, sustainability-linked financing, thematic bonds and blended-finance structures supported by guarantees, concessional funding and risk-sharing mechanisms. Institutions should align products with the Ghana Green Finance Taxonomy and national development priorities.
Blended finance will be important because many climate projects face high initial costs, long repayment periods and risks that commercial lenders are unwilling to carry alone. Guarantees, first-loss capital and development-finance participation can make projects investable without abandoning commercial discipline.
Project preparation remains a critical constraint. A taxonomy may identify what qualifies as green, but it cannot turn a poorly designed proposal into a bankable investment. Ghana will need technical capacity to develop feasibility studies, revenue models, environmental assessments and credible implementation structures.
The roadmap also confronts greenwashing. Regulators plan common product labels, minimum disclosure standards and requirements that sustainability claims be accurate, verifiable and not misleading. Internal controls must protect the integrity of ESG disclosures, with supervisory action available when institutions make deceptive claims.
These protections are necessary if Ghana wants to attract international capital. Investors need confidence that a green bond or sustainability-linked loan finances genuine outcomes rather than ordinary expenditure repackaged with environmental language.
Implementation will be overseen nationally by the Financial Stability Council and its Technical Committee. A Bank of Ghana-led inter-regulatory committee will coordinate the sector regulators, while each authority translates the roadmap into rules and supervisory expectations for its institutions.
The approach will be phased. Early work will establish governance arrangements, build capacity, issue foundational guidance and improve data. Later phases will deepen risk management, disclosures, scenario analysis and supervisory assessments as markets and institutions mature.
Each regulator must submit biannual progress reports outlining completed actions, challenges and priorities. Institutions will be assessed through off-site monitoring, on-site examinations, thematic reviews and supervisory engagement, with sustainability findings increasingly influencing risk assessments and corrective action.
The reporting arrangement creates an accountability mechanism, but the decisive test will be public evidence of change. Progress should eventually be visible in capital mobilised, risks reduced, projects completed, disclosures improved and communities made more resilient.
Ghana has already developed sustainable banking principles, a green finance taxonomy, carbon-market arrangements and sustainability-reporting structures. The roadmap attempts to connect these separate initiatives into one financial-sector strategy.
Its greatest strength is recognising that sustainable finance is neither charity nor public relations. Climate damage can weaken borrowers, destroy collateral, increase insurance claims and undermine investment returns. Financing resilience is therefore compatible with protecting balance sheets and retirement savings.
Its greatest risk is that institutions comply on paper while capital allocation remains unchanged. Committees, policies and reports will achieve little if lenders continue ignoring climate exposure or if labelled products fail to finance measurable environmental and social outcomes.
The roadmap gives Ghana a regulatory architecture for action. Turning it into economic transformation will require enforceable rules, reliable data, investable projects and institutions willing to price long-term risks that conventional finance has often overlooked.
If implementation succeeds, Ghana’s financial system could become a stronger source of capital for resilient infrastructure, cleaner energy, agriculture and inclusive enterprise. If it stalls, the country will retain an impressive framework while its climate-financing gap and vulnerability continue to grow.
