South Korea plans to require large companies to publish mandatory sustainability reports starting in 2028. The rule will apply first to major firms listed on the country’s main stock exchange.
Starting in 2028, KOSPI (the largest South Korean stocks) companies with at least 30 trillion won (around $22 billion) in assets will need to reveal their environmental, social, and governance (ESG) practices.
South Korea’s Sustainability Reporting Era Begins
The reporting requirement will expand in 2029 to companies with 10 trillion won or more in assets. The first phase will focus on about 58 of South Korea‘s largest listed companies. This is based on estimates from the Financial Services Commission (FSC).
Companies must publish clear details on climate risks, emissions, governance, and sustainability strategies. These disclosures will cover greenhouse gas emissions, climate financial risks, and plans to achieve climate goals.
The government says the policy will improve transparency for investors and strengthen confidence in Korea’s financial markets. It will also help the country align with global ESG reporting standards that investors increasingly expect.
South Korea has big industrial companies operating in electronics, cars, steel, and shipbuilding. These industries play a major role in global supply chains. Clear sustainability reporting could help these companies maintain access to international capital and markets.
A Gradual Rollout to Ease Corporate Burden
In 2026, South Korea’s Financial Services Commission released a roadmap for ESG disclosure. The policy forms part of the government’s broader strategy to support the country’s green transition.

Officials decided on a phased rollout to give companies enough time to prepare. Key elements of the plan include:
- Mandatory ESG reporting for large KOSPI companies starting in 2028.
- Expansion to additional companies in 2029.
- Full adoption of supply-chain emissions reporting by 2031.
Companies will receive a three-year grace period before they must disclose Scope 3 emissions. These emissions include indirect emissions across a company’s value chain. These can come from suppliers, transportation, product use, and waste.
For many firms, Scope 3 emissions represent the largest share of total emissions. The Carbon Disclosure Project (CDP) states that Scope 3 emissions can be over 11 times greater than direct operational emissions for many companies.
Regulators gave companies more time to create systems for measuring these emissions due to the complexity involved.
Initially, the rules will operate through stock exchange disclosure requirements. Over time, the government plans to convert them into formal legal reporting obligations.
How Climate Finance Powers Korea’s Green Shift
The new reporting framework supports South Korea’s broader climate policy and energy transition. The government aims to raise about 790 trillion won (around $590 billion) by 2032.
The funding will support climate-related investments and help industries modernize and reduce emissions. Priority sectors include renewable energy, hydrogen technologies, green infrastructure, low-carbon manufacturing, and energy efficiency upgrades.
Heavy industries are a key focus of these efforts. South Korea is a top producer of steel, petrochemicals, and semiconductors, which need a lot of energy. The country generates 33% of its electricity from coal, per International Energy Agency data.

The IEA says South Korea was one of the top ten energy consumers in 2024. Industry made up a large part of the electricity demand. The government will introduce transition finance frameworks. These will help high-emission industries get funding for cleaner technologies.

South Korea has pledged to reach carbon neutrality by 2050. The country also aims to reduce greenhouse gas emissions 40% below 2018 levels by 2030 under its updated climate plan. Stronger ESG reporting will help investors measure corporate progress toward these goals.

Why Mandatory ESG Reporting Is Going Global
South Korea’s policy reflects a global shift toward mandatory sustainability reporting. Governments and regulators increasingly require companies to disclose climate risks and emissions data. These rules show how climate change and energy policies can impact businesses.
The EU’s Corporate Sustainability Reporting Directive (CSRD) is a major reporting framework. The rule will eventually apply to around 50,000 companies operating in Europe, according to the European Commission.
Global standards are also emerging. The International Sustainability Standards Board (ISSB) released two key disclosure standards in 2023:
- IFRS S1, covering general sustainability disclosures
- IFRS S2, covering climate-related disclosures
More than 20 jurisdictions representing over half of global GDP have announced plans to adopt or align with ISSB standards. South Korea’s reporting framework follows these international guidelines.
The country set up the Korea Sustainability Standards Board (KSSB). Its job is to create national reporting standards that match the ISSB framework.
Companies will be required to disclose:
- climate risks and opportunities,
- governance structures for sustainability oversight,
- emissions data and reduction targets, and
- strategy and risk management practices.
This alignment helps investors compare companies across different markets using similar data.
Korean Corporations Step Up Sustainability Disclosures
Corporate sustainability reporting has already expanded in South Korea. By 2024, about 203 Korean companies will publish voluntary sustainability reports. This comes from ESG research groups that track disclosure trends.
Large Korean firms have increasingly adopted global reporting frameworks such as:
- Task Force on Climate-related Financial Disclosures (TCFD)
- Global Reporting Initiative (GRI)
- Sustainability Accounting Standards Board (SASB)
However, many companies asked regulators to delay mandatory reporting requirements. Businesses said they need more time to create reliable emissions measurement systems and reporting processes.
The government responded by pushing the start date to 2028. The extra time helps companies create internal ESG management systems and enhance data collection. Financial institutions strongly support stronger sustainability disclosure.
Investors increasingly use ESG data when evaluating risk and long-term performance. According to the Global Sustainable Investment Alliance, sustainable investment assets reached over $30 trillion globally in recent years. Analysts forecast it to reach $40 trillion by 2030.

Transparent ESG reporting helps companies attract capital from these investors. It also helps banks and asset managers assess climate risks across their portfolios.
The Future of ESG Disclosure in Asia
South Korea’s new rules could influence ESG reporting across Asia. Several financial centers in the region are strengthening climate reporting policies.
For instance, Japan plans to expand sustainability disclosure rules for major companies beginning around 2027. The country now requires climate risk disclosures for companies on its Prime Market. These disclosures must follow the TCFD framework.
Singapore and Hong Kong are both starting mandatory climate reporting that will follow ISSB standards. China is also expanding its climate disclosure rules to other major sectors.

These developments reflect growing pressure from global investors. Many asset managers now need detailed climate data from companies. They use this information before deciding on investments.
Consistent reporting frameworks also help multinational companies operate across multiple markets. Large corporations often face different disclosure rules in different countries. Aligning with global standards can reduce compliance costs and improve transparency.
As more countries adopt ESG reporting rules, sustainability reporting may become as common as financial reporting.
Transparency as the New Standard in Global Markets
South Korea’s plan to introduce mandatory sustainability reporting in 2028 marks a major step in the country’s climate and financial policy. The phased rollout will start with the largest listed companies and later expand to more firms. Companies will need to disclose detailed data on emissions, climate risks, and sustainability strategies.
The policy aims to improve transparency for investors and align South Korea with global ESG reporting standards. As sustainability disclosure becomes more common worldwide, companies with strong climate strategies and clear reporting systems may gain an advantage in global capital markets.

Climate-Linked Supply Chain Risk Is Already in Your P&L
The earnings calls that quietly reframed climate from sustainability question to operating risk.
Three earnings calls in the last 18 months tell the story without any help from a press release.
Hershey, May 2024: cocoa price exposure compresses margin, and the company attributes part of the cost shock to West African weather. Olam, July 2024: coffee climate exposure quantified in the annual report. JBS, January 2025: supply chain climate disclosures expanded materially in response to investor pressure and regulatory expectation. None of these companies issued the announcement as climate news. They issued it as financial news. The climate-linked supply chain risk did not arrive with a sustainability framing; it arrived as a P&L line.
You are probably reading this article because you suspect the same thing is happening to your business. This piece walks through what is showing up on which earnings calls, how procurement and finance leaders are quantifying the exposure, and what serious corporates are doing about it before the regulator asks.
Where climate risk has already appeared in earnings
The pattern is consistent across resource-intensive sectors. A weather event compresses supply, the price spikes, the cost flows through the income statement, and the analyst on the call asks whether the event is anomalous or structural. Increasingly, the honest answer is the second one.
Cocoa is the cleanest example. The 2023 to 2024 West African harvest fell sharply on the back of erratic rainfall and disease. Cocoa futures more than tripled. Companies with concentrated West African sourcing absorbed the cost; companies with diversified sourcing absorbed less. The exposure was not climate as ESG topic. It was climate as cost of goods.
Coffee follows the same pattern. Brazilian and Vietnamese harvests have moved on weather more sharply across the last several seasons. Roasters with long-tenor supplier relationships and origin diversification have managed the volatility; roasters with spot-market exposure have not. Wheat, sugar, palm oil, beef: the same dynamic in different commodities, a pattern the IPCC AR6 Working Group II report projects will intensify across agricultural systems through mid-century.
What this means: climate risk is no longer a footnote in the 10-K. It is a line item the CFO has to explain on the call.
The three commodity exposures that hit margin first
For most companies with material Scope 3 exposure, three exposures dominate the near-term P&L risk.
- Concentrated single-origin sourcing in a climate-vulnerable region. If your tier-one supply for any material commodity sits in one geography, you have a concentration risk that climate amplifies. Diversification across origins is the obvious hedge, but it takes years to build and requires relationships you cannot acquire by tender.
- Supplier financial fragility under climate stress. Smallholder farmers, who supply a large share of the global cocoa, coffee, and palm oil market, do not carry the balance sheets to absorb yield shocks. When yields collapse, they exit. When they exit, your supply base shrinks, and the surviving suppliers raise prices. The risk is structural, not cyclical.
- Logistics and storage exposure to extreme weather. Hurricane disruptions to Gulf shipping, drought-driven Panama Canal restrictions, flooding in European inland waterways: each of these has moved input costs in the last three years, a pattern documented in Munich Re’s natural catastrophe data. The exposure shows up as a one-quarter event in the financial press but accumulates over time on the cost line.
TCFD and ISSB disclosure changes
The disclosure architecture has now caught up with the risk. The Task Force on Climate-related Financial Disclosures, whose recommendations are now embedded in the ISSB’s IFRS S2 climate standard, requires companies to disclose climate-related risks across physical and transition categories, with quantification where possible.
For physical risk specifically (the climate-linked supply chain risk you are reading about), the disclosure must address both acute exposures (extreme weather events) and chronic exposures (gradual changes in temperature, precipitation, and growing seasons). The disclosure must address the time horizon over which the risk is material, the parts of the value chain exposed, and the financial impact under different scenarios.
The CSRD imposes similar requirements under European law, with double materiality (both financial and impact materiality) embedded in the assessment. The practical effect: your auditors and your investor relations team now need a defensible answer to the climate-linked supply chain risk question, and the answer needs to be quantified.
What procurement and finance can do now
Three actions matter near-term.
Map your exposure. Most companies do not have a clear view of which tier-one and tier-two suppliers sit in which climate-vulnerable geographies. Without the map, you cannot quantify the risk, and without the quantification, you cannot disclose it credibly. The map is the foundation, and World Resources Institute climate risk research provides useful public tooling to start.
Diversify and deepen, in that order. Diversification across origins reduces concentration risk, but the deeper move is to invest in the resilience of the suppliers you already have. Regenerative practices, agroforestry, soil health interventions: these reduce yield volatility under climate stress and protect your input cost trajectory.
Embed the climate spend inside procurement, not outside it. Treating climate risk as a sustainability cost line subordinates it to the ESG budget. Treating it as a procurement and resilience investment puts it in the budget that matters, which is the cost-of-goods budget that the CFO defends quarterly.
Nature-based supply chain investments are the asset class designed for exactly this purpose. They sit inside the value chain, they reduce climate-linked supply risk, they generate verifiable Scope 3 reductions, and they produce the documentation an auditor and a regulator can both test.
If you are quantifying climate-linked supply chain risk in advance of the next earnings cycle or the next disclosure period, the carbon and sustainability experts at Carbon Credit Capital can help you map your exposure and structure a Dual-Value Model response that addresses reduction, resilience, and disclosure-readiness in a single program.

Carbon Footprint
Where should an SME start with a carbon action plan?
More and more small and medium-sized businesses are hearing the same question from their larger customers: What is your carbon footprint? That question now travels down entire supply chains, and it arrives next to tender requirements, certification criteria, and rising customer expectations.

Insetting vs Offsetting: Which Actually Counts Toward Your Scope 3 Targets
The accounting differences that decide whether your nature investment shows up in inventory, in BVCM, or nowhere at all.
The question reaches a procurement team about three weeks before the next sustainability committee meeting. Someone has read about insetting. Someone else has just signed off on an offset purchase. The CSO wants to know if the two are interchangeable. The answer is no, and the GHG Protocol Land Sector and Removals Standard is the reason why.
This article walks through what each term means at audit-grade specificity, what the standards actually say about how each gets counted, and how to decide which tool fits which target. The insetting vs offsetting question is one of the most-searched in corporate climate strategy, and one of the most poorly answered. By the end of this piece, you should be able to brief a committee on the difference without notes.
The two definitions, in plain English
Offsetting means buying carbon credits generated outside your value chain and retiring them against your residual emissions. The reduction happens somewhere else, financed by you, and the credit is the receipt.
Insetting means investing in emission reductions or removals inside your own value chain, typically with suppliers, where the reduction is directly linked to the products and services you buy. The reduction happens inside the boundary of your Scope 3 inventory, and the accounting treatment is fundamentally different.
The shorthand from the University of Oxford’s Nature-based Insetting Initiative is useful: insetting is what you do with the supply chain you have; offsetting is what you do with the supply chain you do not have.
What the GHG Protocol Land Sector Standard actually says
The GHG Protocol Land Sector and Removals Standard, finalised in 2024 after a multi-year pilot, sets the rules for how land-based emission reductions and removals enter corporate inventories. The Standard distinguishes between inventory accounting (Scope 1, 2, and 3) and project or intervention accounting (a separate methodology for crediting).
For insetting, the practical implication is that supplier-level interventions, when properly measured and attributed, can reduce your Scope 3 category 1 (purchased goods and services) emissions in your inventory. The reduction is not a credit retired against the inventory; it is a lower inventory number, period.
For offsetting, the credit is retired separately. It can be reported as a contribution toward a net-zero claim under the SBTi Beyond Value Chain Mitigation framework or as part of a VCMI Carbon Integrity claim, but it does not lower the inventory number.
A practical consequence: if your Science Based Target requires a 50% absolute reduction in Scope 3 emissions by 2030, insetting moves you toward the target. Offsetting does not. This single point of difference reshapes the procurement decision.
When insetting counts toward Scope 3 (and when it does not)
Insetting counts toward Scope 3 only when several conditions are met:
- The intervention must occur with an entity in your value chain.
- The emissions reduction or removal must be measured against a defensible baseline.
- The reduction must be attributed to your share of that supplier’s output, not double-counted with other buyers.
- It must follow the inventory accounting rules in the GHG Protocol Land Sector Standard, not the project accounting rules used to generate credits.
The most common failure mode is double counting. If your supplier sells the same reduction as a credit on the voluntary market and also reports it to you as a Scope 3 reduction, the math breaks. The Standard requires you to address this risk, typically by purchasing and retiring the supplier-issued credit as part of your inventory or by contractual provisions that prevent the supplier from selling the reduction twice.
When insetting does not count toward Scope 3: when the intervention sits with a supplier you do not buy from, when the baseline is not defensible, when the attribution is unclear, or when the documentation does not survive audit. Those cases default to Beyond Value Chain Mitigation, which is still useful but operates on a different ledger.
The procurement and supplier engagement question
Insetting is harder than offsetting. That is the unfashionable truth most buyers eventually confront. Offsetting is a transaction; insetting is a relationship.
To run an insetting program, you need supplier mapping precise enough to know which farms or facilities sit at which Scope 3 boundary. You need an engagement model that gets suppliers to participate, which usually requires multi-year commitments and shared economics. You need an MRV architecture that measures the right things and produces audit-ready documentation. And you need a contractual structure that prevents double counting and protects both sides.
The trade-off you receive in return is significant. Reductions count against your inventory rather than your residual. Supplier relationships deepen, which protects sourcing continuity. Yield and quality improvements often follow regenerative interventions, which reduces your input cost over time. And the regulatory file, under CSRD, CSDDD, EUDR, and the SBTi FLAG Guidance, is materially stronger.
Choosing the right tool for the right target
A practical decision rule. If your target is a science-based Scope 3 reduction and you operate in a FLAG sector or source FLAG commodities, insetting is the structurally correct tool. If your target is a net-zero claim that includes neutralising hard-to-abate residual emissions outside your value chain, BVCM via high-integrity offsets is the structurally correct tool. Most companies with material Scope 3 exposure need both, in different proportions, sequenced over time.
The sequencing matters. Insetting takes longer to stand up but produces a permanent reduction in the inventory. Offsetting can be transacted faster but does not change the inventory and now sits under tighter claim restrictions. Treat them as complementary tools with different jobs, not as substitutes. The Accountability Framework Initiative and the IUCN Global Standard for Nature-based Solutions both provide useful guardrails for the insetting side, with biodiversity, human rights, and benefit-sharing requirements that go beyond carbon math.
If you are mapping a Scope 3 reduction roadmap and need to scope which interventions count toward your inventory versus which sit in Beyond Value Chain Mitigation, the carbon and sustainability experts at Carbon Credit Capital can help you structure a nature-based supply chain investment program that fits your FLAG exposure, your target architecture, and your audit horizon.
