The Year in Sustainability: September's Top Stories 2025

Sweep: The Future of Sustainability Data Management
"I am so proud of what we have created, of our committed team, of the great partnerships we have built and are continuing to build with some extremely large companies, ones which have the most complex sustainability programs and demands, like L’Oréal or the French railways company SNCF," says Rachel Delacour, the CEO and Co-Founder of Sweep.
"It's never easy to start a business from scratch, and more importantly when you’re doing so in order to address a transformation within companies. Fifteen years ago we all experienced the digital transformation for companies, and the ones who managed to navigate it and transform themselves the right way are thriving today."
Novisto: Championing Sustainability & Shareholder Value
Set against the backdrop of one of the largest globally recognised climate summits in the world, Novisto sponsored Sustainability LIVE Climate Week NYC 2025.

Roche: The World’s Second Most Sustainable Company 2025
Roche has secured the number two position in the Top 250 World's Most Sustainable Companies list for 2025, affirming its leadership and unwavering commitment to sustainability across global healthcare and diagnostics sectors. This accolade places Roche among the very best in sustainable corporate practices and reflects its broad impact on society, the environment and the future of medicine.
“It gives me immense pride to publish the expanded list of the Top 250 World's Most Sustainable Companies, especially as I’ve got to know so many of the amazing companies on the list,” says Glen White, CEO of BizClik and Sustainability Magazine.
“I recognised at our inaugural Climate Week NYC event last September, that we have started to build something quite special with Sustainability Magazine and Sustainability LIVE – a collective collaboration of likeminded individuals and teams all committed to achieving long-term programmes to protect our planet.”
Sustainability Reports – are they Dying or Evolving?
Anybody working in sustainability knows that 2025 has been a bumpy ride.
The inauguration of US President Donald Trump was followed by intense pressure on companies to ditch DEI policies – and a renewed focus on oil and gas in the US.
For some, ‘sustainability’ has become a four-letter word. And that seemed to be supported by a 52% fall in the number of sustainability reports published in H1 by the 3,000 largest US companies.
During this period, 432 companies in the Russell 3000 index filed a sustainability report, according to The Conference Board.
That is a 52% drop compared to the same period in 2024, when 831 companies had done so.
Adobe, GM, Citi and Uber were among those delaying their sustainability report publication amid regulatory and political shifts.
