Sustainability Forward

Electricity is becoming the backbone of the modern economy — powering transport, heating, industry, cooling, digital infrastructure and increasingly, AI. But as demand grows, can we really build a power system that is 100% decarbonised?

In this episode of Sustainability Forward, Wrishi and Carmine explore what “100% clean electricity” actually means, and why the final stretch of decarbonisation is often the hardest. They discuss the role of wind and solar, storage, grid expansion, demand flexibility, firm clean power, geothermal, market design and public acceptance.

The conversation also looks at real-world examples, including Uruguay’s near-100% renewable electricity system and South Australia’s rapid shift towards high levels of wind and solar. The episode opens with a striking comparison between a proposed 9 GW AI data centre campus in Utah, the Boeing Everett factory, and the electricity consumption of the entire state of Utah — a reminder that the clean power challenge is not just about today’s grid, but the much larger grid of the future.

A practical, accessible conversation on whether 100% decarbonised electricity is possible — and what it would actually take to get there.

In this episode of Sustainability Forward, we speak with Jennifer Motles, Chief Sustainability Officer at Philip Morris International, about what sustainability leadership looks like inside a complex global business undergoing transformation.

Jennifer shares her journey into sustainability leadership and explains how she sees the role of a CSO: not as a side function, but as a driver of long-term value creation, resilience, and business transformation. The conversation explores why sustainability must start with a company’s most material impacts, how systems change requires action far beyond one company alone, and why transformation should be understood not as a project with a clear end point, but as continuous “change in motion.”

We also discuss what it takes to drive change across a large organisation, how senior leadership alignment shapes progress, and why credibility comes from outcomes, evidence, and transparency around both achievements and limitations. Jennifer offers a candid perspective on trade-offs, accountability, and the realities of working on difficult sustainability challenges where change is often slower and messier than outside observers expect.

This episode will be especially relevant for sustainability professionals, business leaders, and anyone interested in how real transformation happens inside large organisations.

Topics covered:

• Jennifer Motles’ journey into sustainability leadership

• Why sustainability matters in the context of business transformation

• Systems change and the role of business in tackling complex challenges

• How to drive change across strategy, operations, and leadership

• Credibility, accountability, and evidence in sustainability

• Why transparency about trade-offs and limitations matters

• Advice for people trying to create meaningful change inside complex organisations

A thoughtful episode on leadership, realism, and why the hard work of sustainability happens from within.

In this episode of Sustainability Forward, we turn our attention to one of the most practical — and often underestimated — parts of the climate challenge: buildings.

After previously exploring the carbon footprint of individuals, we saw that while transport dominates, the home is not far behind. And unlike transport, buildings are one area where change can happen now.

To help us unpack the challenge, we are joined by Ascanio Vitale, a sustainability science expert with more than 30 years of experience in environmental advocacy and decarbonisation. With a background spanning engineering, policy, and consulting, Ascanio has worked with Greenpeace, WWF, the European Commission, and now leads Stop CO2, where he advises on sustainability and ultra-efficient buildings.

Together, we explore why building retrofit is still moving too slowly, what households can do first to reduce energy use and bills, why commercial buildings struggle with split incentives, whether current grants and subsidies are working, and which technologies are genuinely promising.

This is a conversation about more than carbon. It is about comfort, health, resilience, affordability, and how better buildings can become a real part of the transition.

In this episode of Sustainability Forward, Wrishi and Carmine explore the new logic of clean resilience.

Against the backdrop of the current Middle East crisis, they examine why the implications go far beyond oil prices. The conversation looks at three connected themes: how renewables are coming into sharper focus as an energy security lever, why water resilience and desalination can no longer be separated from power-system design, and how disruptions to critical commodities such as fertiliser and helium reveal the fragility of global supply chains.

Rather than treating clean energy as only a climate solution, this episode asks a bigger question: are we entering a period in which clean energy, clean water and diversified supply systems become essential pillars of resilience?

A timely discussion on energy, infrastructure, security and what the future may demand from more resilient systems.

AI is everywhere in sustainability right now — but what’s genuinely changing on the ground, and what’s still hype?

In this episode of Sustainability Forward, hosts Wrishi Sutradhar and Carmine Fiume sit down with Carlos Silva Willson, a global technology and partnerships leader at Microsoft Middle East with prior experience across GE/Baker Hughes and AWS.

Carlos brings a practical, “been-in-the-room” perspective on what AI and cloud can realistically deliver for sustainability — and what leaders should be cautious about as adoption accelerates.

In the conversation, we cover:

• Where AI + cloud are already creating measurable sustainability value (beyond dashboards and buzzwords)

• Why partnerships and ecosystems matter if climate solutions are going to scale

• The hard questions around AI’s footprint: data centres, energy demand, and water use

• How to think about trust, accountability, and credible impact claims

• The changing talent landscape: the skills that will define climate-tech careers in the years ahead

If you work in sustainability, climate-tech, energy, or digital transformation, this episode will help you separate signal from noise — and focus on what’s scalable, credible, and useful.

What if the modern version of a UK allotment isn’t a patch of land—but a classroom?

In this episode of Sustainability Forward, we speak with Alex Tyink, co-founder and CEO of Fork Farms, whose unlikely journey from opera singer to urban farmer began on a rooftop in Brooklyn—and turned into a mission focused on food access with dignity.

We explore why food is one of the most practical entry points into sustainability: it’s daily, personal, and deeply connected to health, community, and resilience. Alex explains why Fork Farms focuses on enabling others to grow (rather than operating farms themselves), why highly perishable foods like leafy greens matter most, and what changes when students grow food that ends up on the school lunch line.

We also get into the real-world side of scaling: what breaks in deployments, how you design for people who have never grown anything, and where AI can genuinely help day-to-day operators without becoming hype.

In this conversation:

• Alex’s Brooklyn rooftop turning point—and how growing food reshaped purpose and wellbeing

• Food access beyond price and calories: dignity, trust, and control

• Why schools are the best place to start—and what happens when kids eat what they grow

• Scaling distributed indoor growing without the “giant vertical farm” trap

• Where automation and AI can improve consistency and operational confidence

If you’re looking for sustainability that feels human, practical, and achievable, this episode is for you.

As energy systems become more complex and data intensive, organisations face a critical challenge: how to scale reliability, throughput, and decision quality without proportionally scaling headcount.

In this episode of Sustainability Forward, hosts Wrishi and Carmine explore how agentic AI represents a shift from AI as a productivity tool to AI as a trusted teammate embedded directly into operational workflows.

Joined by Subodh Kumar, they discuss:

• Why cognitive load is the real constraint inside modern energy organisations

• The difference between traditional AI copilots and agentic AI systems

• Real world applications across maintenance diagnostics, process safety, engineering handovers, and operational decision support

• How to design human oversight and accountability in AI enabled environments

• How leaders must rethink organisational structure and governance to deploy AI safely

The episode draws from Subodh’s book, Agentic AI for Leaders, which offers a practical executive framework for integrating AI into enterprise decision making while preserving accountability and safety.

What happens when the world doesn’t just face water scarcity — but water bankruptcy?

In this episode of Sustainability Forward, we unpack a stark new warning from the United Nations: many of the world’s freshwater systems are now so over-used and degraded that they may never recover to their historical levels.

We explore what “global water bankruptcy” actually means, why this framing is different from how we’ve talked about water crises before, and what the implications are for food systems, economies, geopolitics, and climate resilience.

From collapsing aquifers and rivers that no longer reach the sea, to the hidden role of groundwater in global food production, this conversation connects water to some of the biggest challenges facing societies today.

Most importantly, we discuss what can still be done — and why managing water bankruptcy requires political courage, hard limits, and a fundamental rethink of how we value water.

This episode is for anyone interested in sustainability, climate risk, food security, and the invisible systems that underpin modern life.

We often think individual climate action is about small, visible choices — what we eat, what we recycle, or whether we switch off the lights.

But do those actions really matter most?

In the first episode of the new year, Wrishi Sutradhar and Carmine Fiume take a data-driven look at where personal emissions actually come from. Using concrete examples, we walk through the biggest drivers of individual climate impact: cars and mobility, flying, home energy and heating, food choices, and consumption.

Along the way, we unpack why some actions dominate emissions while others receive disproportionate attention — and why context matters so much. Where you live, how your energy is produced, your travel patterns, and your housing all shape your footprint in very different ways.

This episode isn’t about being a “perfect green consumer.”
It’s about understanding impact, prioritising the right levers, and moving the conversation away from guilt and toward agency.

If you’ve ever wondered where to actually focus your energy when it comes to climate action, this episode is a good place to start.

In this Season 3 finale of Sustainability Forward, hosts Wrishi Sutradhar and Carmine Fiume look back on the year — but not as a simple recap.

Instead, we retell Season 3 as one connected story: a journey through the messy middle of sustainability, where progress depends on incentives, trust, execution, and real-world adoption.

Across the season, we explored the topics shaping today’s sustainability and energy transition conversation — from impact investing and climate finance, to electrification of heating (heat pumps), resilience and food systems, and the growing importance of data, measurement, reporting and verification (MRV).

This finale brings together the biggest insights from our guests and episodes, including:

• Can we make money while saving the planet? (impact investing + incentives)

• Why heat pumps and electrification matter for decarbonising homes

• Resilience at household level: backyards, preparedness, community

• Soil health, regenerative agriculture, and making climate tangible through food

• Sustainability communication, trust, and avoiding greenwashing

• Science, solar, and the realities of scaling the energy transition

• AI for climate: opportunity, risk, and rising energy demand

• Methane transparency and why MRV is becoming market infrastructure

• The ESG backlash: reporting vs performance, and the role of corporate courage

• Capital markets and what “mobilising trillions” really requires

• Planetary boundaries and why sustainability is bigger than carbon

• Emerging markets and renewables: India and Pakistan — same sun, different stories

We close with our key learnings from the season and a forward-looking view of what 2026 may demand: proof over promises, better execution capacity, credible disclosure, and trust as a foundation for climate and sustainability action.

If you want a thoughtful, practical synthesis of sustainability, ESG, climate tech, climate finance, and the energy transition — this episode is for you.
