As the sustainability landscape continues to evolve, 2025 has brought with it a powerful mix of breakthroughs, regulation, and resilience in the face of political turbulence. From China’s historic emissions drop to the Middle East embracing carbon accountability, here are five essential global developments—and why they mark real progress.

1. China cuts emissions despite population growth — a historic inflection point

What happened:
In Q1 2025, China reduced its carbon emissions by 1.6% year-on-year, despite a growing population and increased industrial output. This decline was primarily driven by a doubling of solar capacity since 2022, and a 45% increase in wind energy generation. The country also commissioned 5 new nuclear reactors in the past 12 months.

Why it’s progressive:
This is the first time China’s emissions have declined due to clean energy scale-up, not economic slowdown. For the world’s largest emitter to begin decoupling growth from carbon is a milestone—proof that climate ambition can be a central part of economic strategy, not a trade-off.

2. New York State pension fund: capital reallocation with teeth

What happened:
The NY State Common Retirement Fund has committed $2.4 billion to sustainable investments and is rolling out a regime that requires portfolio companies to disclose Scopes 1, 2, and 3 emissions. So far in 2025, it has already divested from 21 companies failing to meet climate risk standards.

Why it’s progressive:
This isn’t just greenwashing. It’s a major institutional investor using capital as leverage for accountability. It proves ESG isn’t going away—instead, it’s maturing, with a focus on measurable performance, not vague commitments.

Despite the backlash:
Even amid anti-ESG rhetoric in U.S. politics—particularly under the Trump-aligned policy proposals—state-level actors like New York are demonstrating that fiduciary responsibility and climate risk are inseparable.

3. Australia implements ASRS — sustainability disclosure goes mainstream

What happened:
As of January 1, 2025, Australia’s ASRS is now mandatory for around 3,200 large and listed entities, requiring detailed disclosure of climate-related risks and opportunities. The legislation includes penalties of up to AUD 1.1 million for companies failing to comply.

Why it’s progressive:
This is a turning point for the Asia-Pacific region. Australia’s move sends a message to business and finance alike: climate risk is financial risk. No longer confined to niche reporting, sustainability is being absorbed into mainstream corporate governance.

4. IFRS S1 & S2 take global hold — a unified baseline emerges

What happened:
The IFRS Foundation’s ISSB standards—IFRS S1 (general sustainability disclosures) and S2 (climate-specific)—are now adopted in 42 countries as of May 2025. Early adopters include the UK, EU member states, Japan, Brazil, and Canada. Over 5,000 companies globally are now reporting under IFRS S1/S2.

Why it’s progressive:
For the first time, businesses have a global baseline that brings comparability, consistency, and clarity. This reduces compliance chaos and levels the playing field—especially for multinationals juggling multiple frameworks.

Yes, the CSRD Omnibus delay is frustrating—but it’s not derailment. Europe’s broader ESG direction remains intact, and CSRD will still usher in a new era of granular, auditable sustainability data. Meanwhile, IFRS’s clarity gives businesses something real to build toward.

5. The Middle East and Africa embrace mandatory carbon reporting

What happened:
2025 has seen a surge in mandatory carbon reporting across the Middle East and Africa:
UAE: As of June 2025, over 1,200 companies are now registered in the National Carbon Credit Register, which requires third-party verified emissions data.
Kenya & South Africa: New climate laws require GHG reporting for all companies above a certain energy use threshold.
Saudi Arabia & Qatar: Climate risk disclosure rules are being finalized for release by Q4 2025.

Why it’s progressive:
These are regions historically overlooked in global ESG conversations—yet they’re now implementing regulatory structures faster than some developed economies. This demonstrates that climate policy isn’t just a Western agenda—it’s becoming a global norm.

Final take: progress isn’t perfect, but it’s real

Despite some headwinds—including:

• Delays in the EU’s CSRD omnibus package
• Pushback from U.S. conservative policymakers against ESG
• Slower-than-expected adoption in some emerging markets

…the overall direction in 2025 is unambiguously forward.

• Capital is flowing toward climate-aligned assets
• Major emitters like China are shifting their emissions trajectories
• And the alphabet soup of reporting standards is finally consolidating, making it easier for companies to comply with confidence.

For sustainability professionals, the message is clear:

We’re not debating if climate disclosure becomes the norm—we’re debating how fast and how robust.
