Climate Week NYC 2026: Key ESG, CSRD & Sustainability Reporting Trends every business should watch
Mark your calendars: Climate Week NYC is officially back. It’ll take place from September 20th to 27th, 2026, and is expected to be the biggest Climate Week ever! Coordinated by The Climate Group – the nonprofit organization that has been organizing Climate Week for almost two decades, Climate Week NYC 2026 will feature over a thousand events and over 100,000 visitors in New York City over eight days. The agenda has been strategically chosen to coincide with the United Nations General Assembly so policymakers, investors, and corporate leaders are in New York during the same week.
The Climate Week NYC 2026 schedule is as follows: Opening Ceremony on Monday, September 21st; a two-day The Hub Live program (plenaries, panels, and roundtables), followed by events spread across the city at more than 1,000 satellite events organized by businesses, governments, and civil society organizations. Rather than one event, the entire city becomes part of Climate Week, as business leaders and activists alike converge upon Manhattan to discuss their agendas for a week straight.
That is the news. But more importantly – here is why it actually matters if you run a company in Europe or the United States.
For many organizations, Climate Week is only the visible culmination of months of planning, reporting preparation, and stakeholder engagement. With massive regulatory reform in Europe and changes in global reporting standards, the discussions at Climate Week NYC 2026 will be affected by shifts that many businesses have not yet fully absorbed.
So let us consider what will largely shape the hallway discussions this September, and more importantly, what it means for your still unfinished sustainability report.
The CSRD didn't die. It went on a diet.
If you’ve been paying attention to sustainability news at all since 2025, then you might have heard something about a “CSRD rollback” or “Simplification Omnibus”. A complete rollback is not actually what happened. Instead, what happened is more complex, because it involved moving the compliance threshold, not removing it.
In February 2026, the European Union formally adopted the Omnibus Simplification Package. It’s a package designed to simplify the Corporate Sustainability Reporting Directive and the Corporate Sustainability Due Diligence Directive. Under the adopted Omnibus reforms, the CSRD applies to significantly fewer companies by raising employee thresholds and narrowing the scope of reporting requirements, according to the Council of the European Union’s official description. The reforms also narrow the scope for certain non-EU companies operating within the EU.
Now, the complexity that confuses a lot of people is this: many mid-size companies think they’re exempt from mandatory reporting. But the reality is not that simple Suppliers who fall out of direct scope can still be required to give indirect reports because the companies who are now covered need the supply chain data to complete their own reports. And although the Omnibus package restricts the amount of reporting data a large company can require from a small supplier by tying it to the EU’s voluntary reporting standards for small businesses (VSME), “restricted” doesn’t mean “none at all.” If your client is a large company still covered by the CSRD requirements, then suppliers may still receive requests for emissions data, even though you won’t have to do a full report.
In the meantime, work on developing simplified European Sustainability Reporting Standards has continued. The European Commission is expected to approve the delegated act later this year.
ISSB reporting is quietly becoming the default language of climate risk
As Brussels was busy adapting its own rules, a wider development was taking place behind the scenes: steady but real and significant growth of ISSB reporting as the international standard for sustainability reporting.
According to data provided by S&P Global this spring, 28 jurisdictions have either adopted, announced plans to adopt, or incorporated IFRS S1 and S2 into their regulatory frameworks. This includes major capital markets in the Asia-Pacific region, the Middle East and Latin America, along with the UK Sustainability Reporting Standards (UK SRS).
The United States remains an important exception in the formal adoption of the standards. Still, quite a large number of US multinationals are voluntarily adopting them since their subsidiaries that are listed abroad have no other option but to do it. If a company operates in Singapore, Japan, or Brazil, ISSB reporting will become not an optional supplement but a requirement for gaining access to the market.
This is exactly the issue that can come up in the corridors of Climate Week NYC: “Our European team wonders whether we should be reporting on both CSRD and ISSB and what is expected from our US parent company in internal reporting.” The answer to that question will most likely be yes, at least for some time while both ISSB and EFRAG are trying to improve interoperability between the frameworks.
Physical climate risk stopped being a “someday” problem
Here’s a number that should give procurement and operations professionals pause: an estimated €43 billion in losses in Europe due to a particular combination of heat, drought and floods in the summer of 2022, according to the European Central Bank, as reported in WWD.
The trend on a global scale looks even less positive. Flood losses have increased significantly since 2000, with an average annual cost of $42 billion, says the latest supply chain risk 2026 research by Everstream Analytics.
It also has an even wider impact than one would think: while droughts reduce wheat harvests and lead to price increases for the latter, it then affects companies in various other industries: pharmaceuticals, cosmetics, biofuels, and even plastics – agricultural inputs affect a lot more sectors than most climate risk models take into account.
It serves as an underlying message in the vast majority of programs at Climate Week: climate risk is not solely a matter of the ESG department anymore. It is an operational, balance-sheet problem: will the supplier facility in Valencia get flooded during its peak season, will we find coverage for this facility, and how does it affect our daily operations? And companies that continue treating physical risk assessment as an annual exercise better prepare themselves for some tough times ahead.
It also showcases a divide between “we filed our disclosure” and “we understand our exposure”. One can comply with all CSRD or ISSB disclosure requirements but still lack a forward-looking perspective on which facilities, ports, or supplier hubs will be affected by the next heat or flood event. Disclosure tells regulators about something that already happened, not about what can happen tomorrow. For that, we need data and modeling, not compliance. And this is exactly what climate risk analytics enables.
Corporate sustainability is splitting into two very different jobs
However, there is an innovation that receives too little coverage: corporate sustainability has evolved from a single responsibility into two separate responsibilities.
The first responsibility is reporting. This includes ensuring metric accuracy, adhering to CSRD and ISSB reporting standards, making auditors happy, and avoiding penalties for non-compliance. This task is process-oriented, time-bound, and increasingly implemented using ESG reporting software instead of sustainability managers who try to fill out spreadsheet templates.
The second responsibility is climate resilience. It includes recognizing where a company’s operations, suppliers, and assets are vulnerable to climate risks and building the kind of climate adaptation measures that keep the business running before the disruption hits, not after. This task is foresight-oriented, data-intensive, and likely to be more interesting than completing yet another disclosure template.
Many companies believe that being a good reporter automatically means being resilient. Unfortunately, this assumption is wrong – being diligent in disclosing all required information doesn’t necessarily mean being ready for flooding at a critical supplier location. Current sustainability reporting trends for 2026 include automation and standardization in reporting, which is great because it saves manual work and provides better data quality. However, the same automation allows smart businesses to devote more attention to resilience – proper hotspot mapping, scenario modeling, and stakeholder communications above the bare minimum required by regulators.
This is exactly what Correntics is for: not another reporting tool competing for attention, but the underlying intelligence layer for all of them. Correntics combines the foresight component and digital risk management services to help businesses recognize vulnerabilities in their value chain before it’s too late. Climate risk analytics offered by Correntics allow one to identify supply chain exposure and disruption modeling; real-time hazard data gives the operations team a foresight perspective on extreme events.
So what are the ESG trends 2026 actually pointing to?
When all the acronyms and the sustainability trends noted in 2026 are stripped away, there is a reality that emerges:
- Regulation is becoming more targeted rather than disappearing. While the EU has narrowed the scope of mandatory CSRD reporting, global sustainability disclosure expectations continue to expand through ISSB adoption and supply-chain reporting requirements.
- Physical risk is increasing at a rate that has left most reporting frameworks behind. Disclosure standards define what needs to be reported but do not build the flood model.
- ESG reporting software is taking over the compliance tasks, freeing up the sustainability team from the chore of managing data manually, an opportunity and challenge in equal measures depending on how many of those responsibilities were spreadsheet-based.
- Furthermore, the Corporate Sustainability department, as a business function, now has to prove its worth beyond the mere generation of reports. The board wants to know the potential effects of a climate-related disruption on the Q3 income stream of one of the major suppliers.
Before you head to New York
Even if Climate Week NYC 2026 does not make an appearance on your calendar, the talks set for September at that conference will determine the path of where corporate sustainability, climate risk, and reporting obligations go for the rest of the year. It is clear that there will be less emphasis on reporting volume and more focus on companies knowing their true risks and doing something meaningful with that knowledge.
The winners will not be the companies that generate the most pages of sustainability reports. The winners will be those companies that know beforehand what supplier, what port, and what factory will feel the impact of the next climate crisis, before the regulators, the insurers, or the media force them into it.
This is the gap Correntics aims to fill. Rather than treating climate risk and reporting as two distinct processes, Correntics unifies the predictive hazards with the tools to do digital risk management. These tools include mapping the vulnerable parts of your value chain, assessing risk based on live hazard data, and automatically generating climate and sustainability reports that change yearly with new regulator requirements.
For a company looking to stay up to date with ISSB reporting requirements, the changing CSRD, and hazards that emerge faster than you can write an annual report, this solution is about more than meeting another obligation – it’s about seeing what comes next before disruption occurs.
