Climate Risk Disclosure and the Future of ESG Reporting Standards
How companies talk about their role in climate change has changed a lot. It used to be something they did to show they care, but now it’s one of the most important parts of business rules today. Climate risk disclosure has become the force behind creating new sustainability standards. Companies ignoring this shift are already losing ground.
Shifting from Voluntary Measures to Strict Requirements
Over the past ten years, the Task Force on Climate-related Financial Disclosures (TCFD) has become a leading framework for reporting climate risks. It structured its guidance into four main areas: governance, strategy, risk management, and metrics with targets. By October 2023, the TCFD shut down, not due to failure but because it fulfilled its purpose. The International Sustainability Standards Board (ISSB) took its recommendations and integrated them into two key standards:
IFRS S1 — General Sustainability-related Disclosures
IFRS S2 — Climate-related Disclosures
Today, over 30 jurisdictions are adopting or requiring these standards, signalling a shift from optional guidelines to regulatory obligations.
The Global Shift in Reporting Standards
Different regions are coming together around shared rules. Here's the current situation with major requirements:
Europe (CSRD/ESRS): This uses "double materiality," looking at how business activities affect the climate and how climate changes impact the business.
- Asia-Pacific: Countries like Hong Kong, Japan, Australia, and Singapore are now adopting IFRS S2. They are bringing climate-related details into regular financial reports.
- United States: After the SEC's federal rule was dropped, California's SB-253 and SB-261 stepped in. These rules require companies to start reporting from January 2026.
This shift changes how we define what qualifies as important financial information, placing climate risk right at the core.
Two Key Types of Climate Risk in Disclosure
Current climate disclosure systems ask businesses to address two main risk types:
Physical Risks: These include the direct effects of climate change, like severe weather, floods, droughts, or issues disrupting supply chains.
Transition Risks: These involve financial or policy changes linked to reducing carbon reliance, such as stricter rules, carbon costs, or assets losing value.
Under IFRS S2, companies need to report their Scope 1, 2, and 3 greenhouse gas emissions and perform the required climate scenario analysis. Boards and audit committees are now involved in discussions that used to be handled by sustainability teams alone. This marks a big change in governance.
Why Investors Care
Regulators aren't the only ones driving climate disclosure. The rise of ESG Investing has created a major wave in financial markets, with managed assets expected to go over $40 trillion. Big investors are encouraging the companies they back to follow the ISSB framework. They want more consistency, better comparability, and less greenwashing. Businesses that fail to show they manage climate risks well are losing access to funding and struggling to attract serious long-term investors.
When Climate Reporting Expands Across All Industries
Today, climate risk reporting spreads into nearly every field, not just industries like heavy manufacturing. Scope 3 demands make businesses in areas like consumer products, retail, and manufacturing consider emissions from the end of a product’s life, impacts from suppliers, and how materials are sourced. This pushes companies to rethink processes, put money into sustainable practices, and admit to risks they used to ignore. put, climate guidelines now influence all parts of business activity.
Steps Companies Need to Take Now
The days of casual, optional disclosures are ending. Strong ESG Reporting is no longer a way to stand out. It has become the standard that everyone is expected to meet. Companies need to focus on three key areas to act.
- Improve Governance: Boards should take full responsibility for managing climate risks and make them a central part of their business strategies.
- Create Reliable Data Systems: Companies need systems that ensure emissions data can be tracked and verified through all levels of their supply chains.
- Address Reporting Gaps: Compare current disclosures with CSRD, UK SRS, and ISSB standards to identify and fix gaps before approaching deadlines.

Frequently Asked Questions (FAQs)
1. If climate disclosure matters now more than ever, why did the TCFD disband?
The TCFD wrapped up its work as its mission was fulfilled. The ISSB officially included its guidelines in IFRS S1 and S2, turning what was once voluntary advice into mandatory global standards. This wasn’t stepping back; it was more of passing the torch.
2. Why are Scope 3 emissions the toughest part of climate reporting?
Scope 3 looks at indirect emissions across a company’s entire value chain. This covers everything from what suppliers do to how customers handle and discard products. Companies don’t have much direct control over this information, so getting accurate data is a big challenge for operations.
3. How is "double materiality" under the CSRD different from the ISSB’s approach?
The CSRD asks companies to report on two things: how climate changes impact their business, which is financial materiality, and how their business activities impact the climate, known as impact materiality. The ISSB focuses on financial materiality, which sets it apart and is important for global companies dealing with both systems.
4. Will smaller businesses have to deal with mandatory climate disclosure rules?
Yes. Large companies following CSRD or IFRS S2 rules need to gather Scope 3 data from their supply chains. This means smaller vendors often need to give verified emissions data if they want to keep their major business partners.
