In this episode of Sustainability Matters podcast, host Christian Orth explores how Siemens is using sustainability reporting as a powerful management tool to help steer business performance. As new regulatory frameworks such as CSRD (Corporate Sustainability Reporting Directive) roll out, he explores whether ESG disclosure is simply an administrative burden or a tool to drive real value.

Christian is joined by Thomas Knobloch from Siemens AG and Caroline Pfaff, Partner at EY Germany to break down the practical reality of ESG reporting. Together, they look at the challenge of complex global data, tracking how organizations can move past chasing "perfect" real-time metrics and instead prioritize immediate progress over perfection.

They discuss the real-world operational challenges, how Siemens successfully built a 360-degree target framework directly into its board-level decisions and how focusing on material KPIs, like carbon intensity and product carbon footprints, can simultaneously mitigate long-term risk while unlocking competitive advantages.

Through it all, Thomas and Caroline highlight that building a strong company culture is what can drive true organizational transformation as well as the opportunities to unlock real business value.

In this episode of Sustainability Matters, host David Rae, EY Global Lead for Sustainability Technology and Innovation, explores the impact of AI on climate change. As AI companies build massive data centers worldwide, a critical question emerges: Will the skyrocketing resource footprint of AI push global grids past their limits, or will AI become a vital tool to help accelerate the energy transition?

David is joined by James Grabert from the UNFCCC (United Nations Framework Convention on Climate Change) and Michael Lepech from Stanford University to break down the duality of this digital megatrend. Together, they look at the physical reality behind "the cloud," tracking how AI is driving a massive surge in electricity demand while also leaving an extensive water footprint through data center cooling and the lifecycle of chip manufacturing.

However, they also identify areas of opportunity. The episode offers a hopeful look at "decision intelligence." The guests explain how AI is already delivering measurable climate benefits — from transforming early warning weather models in the Global South to balancing power grids and optimizing renewable energy.

In this episode of the EY Sustainability Matters podcast, Bruno Sarda hosts a discussion with Mark Greatrex, President of Cox Communications, and Tom Kiernan, CEO of American Rivers, about the pivotal role of water in supporting communities and businesses. The guests emphasize that, amid increasing challenges such as nature loss, pollution, drought, flooding and climate extremes, safeguarding rivers is now more critical than ever for commercial interests and economic health.

The dialogue explores how organizations can deepen their understanding of their reliance on healthy river systems, advance solutions through collaborative efforts, and promote water-positive and nature-positive practices.

Additionally, the speakers underscore the importance of strategic partnerships in achieving watershed-scale outcomes. Effective collaboration between businesses and nonprofit organizations facilitates data sharing, strategic alignment, and the development of practical projects that provide multifaceted benefits to communities, industry and ecosystems.

Both guests highlight the value of establishing relationships prior to crises, ensuring that trust and momentum are established when challenges inevitably arise.
