Sustainable Edge: Capital, climate and the next economic transition with Nina Siemiatkowski

Climate may have moved down the headlines, but the challenges facing businesses and society have not gone away. In this episode of Sustainable Edge, Nina Siemiatkowski, co-founder of Milkywire and Flat Capital, explores how capital can accelerate climate and nature solutions, why carbon removal is becoming a critical tool in the net zero transition, and what sustainability leaders can learn from the world of technology and venture capital. In this episode of Sustainable Edge Host Joachim Nahem, Executive Chairman and Co-Founder at Position Green, sits down with Nina Siemiatkowski, co-founder and CEO of Milkywire, entrepreneur, investor, and co-founder of Flat Capital. Nina's journey is anything but conventional. After a successful corporate career, she became a wildlife photographer, spending years documenting ecosystems and biodiversity in Africa. Those experiences exposed her to the realities of biodiversity loss and climate change and ultimately inspired her to build Milkywire, a company dedicated to helping organisations fund high impact climate and nature solutions. Today, Nina operates at the intersection of sustainability, entrepreneurship, and technology. Through Milkywire, she helps companies navigate climate and nature investments, while through Flat Capital she invests in some of the world's most influential technology companies, including OpenAI and SpaceX. Her unique perspective offers valuable insights into how capital, innovation, and long term thinking can help drive the next phase of the sustainability transition. Nina Siemiatkowski shares her perspective on the future of climate action, carbon markets, nature restoration, and entrepreneurship. She explains why sustainability remains a long term economic opportunity despite shifting political priorities and changing market sentiment. Learn about: Capital as a catalyst for climate action Why funding climate and nature solutions remains one of the biggest untapped opportunities for businesses and investors. The future of carbon removal How durable carbon removal is evolving from a niche market into an essential component of credible net zero strategies. Beyond emissions reductions Why businesses need to think not only about reducing emissions, but also about restoring nature and supporting climate solutions. Scaling climate solutions like technology companies What climate entrepreneurs can learn from the growth journeys of successful technology businesses. The risks of premature scaling Why many founders overestimate market readiness and how to balance ambition with discipline. Profit and impact go hand in hand Why long term impact requires financially sustainable business models. Climate, AI, and the battle for capital What today's investment trends reveal about conviction, innovation, and future market opportunities. Reasons for optimism Why Nina believes the sustainability transition is continuing, even if it is happening more quietly than before. About Nina Siemiatkowski Nina Siemiatkowski is the co-founder and CEO of Milkywire, an impact firm helping companies design and manage programs that support climate and nature goals. Milkywire works with leading organisations to fund high quality climate solutions, biodiversity initiatives, and carbon removal projects around the world. Nina is also the co-founder of Flat Capital, a publicly listed investment company that invests in frontier technology companies including OpenAI and SpaceX. Having also witnessed the growth of Klarna from close range, she brings a rare combination of experience across entrepreneurship, investing, technology, and sustainability. A passionate advocate for climate and nature, Nina continues to explore how capital can be directed toward solving some of the world's most pressing environmental challenges. Why it matters As businesses navigate economic uncertainty, geopolitical tensions, and rapid technological change, sustainability can sometimes feel less urgent than it did just a few years ago. Yet climate change, biodiversity loss, and resource constraints continue to shape the long term outlook for economies and markets. Nina argues that the next phase of the transition will be defined not by promises, but by execution. Companies, investors, and entrepreneurs that understand how to combine innovation, capital, and long term thinking will be best positioned to create value while contributing to a more resilient future.

Sustainable Edge: Sustainability, leadership, and competitiveness in a fragmented world with Iván Duque, former President of Colombia

What does it take to lead on climate in a world shaped by distrust, geopolitics, and competing priorities? In this episode, former Colombian President Iván Duque shares how sustainability can be positioned not as a cost, but as a driver of competitiveness, and why leadership matters more than ever in turning ambition into action. In this episode of Sustainable Edge Host Joachim Nahem , Executive Chairman and Co-Founder at Position Green, sits down with Iván Duque , former President of Colombia, to explore what sustainability leadership looks like at the highest level of government. During his presidency, Duque led one of Latin America’s most ambitious climate agendas, balancing economic growth, peacebuilding, and environmental protection. Under his leadership, Colombia expanded protected areas to cover more than a third of its territory and committed to reducing greenhouse gas emissions by 51 percent by 2030 . Today, as global cooperation weakens and political landscapes become more fragmented, the question is no longer just what needs to be done, but how to move forward in a world where trust is declining and priorities are shifting. Learn about: Sustainability as competitiveness Why climate ambition can strengthen economic positioning rather than weaken it Leading through uncertainty What it takes to advance climate action in a world of declining trust and geopolitical fragmentation The role of middle powers How countries like Colombia can shape global cooperation even without the largest economies leading From ambition to implementation What enabled Colombia to pass climate legislation and scale environmental protection at speed Markets and capital flows Why unlocking private finance and market mechanisms is critical for global climate progress Bridging polarization How reframing sustainability conversations can create alignment across political and ideological divides Long term leadership Why sustainability must be embedded into decision making as a core principle of governance and business Beyond politics Beyond his work in policy and sustainability, Iván Duque is also known for an unexpected passion: DJing. What started as a personal interest has become a way to connect with audiences in a completely different setting.

Sustainable Edge: Rethinking corporate accountability in a fragmented world with Robin Hodess, GRI

What does accountability look like in a world shaped by AI, geopolitics, and rising stakeholder expectations? In this episode, Robin Hodess of GRI explores how the role of sustainability reporting is shifting and why companies that treat it as strategic data, not compliance, will be better positioned to compete. In this episode of Sustainable Edge Host Joachim Nahem, Executive Chairman and Co-Founder at Position Green, sits down with Robin Hodess, CEO of the Global Reporting Initiative (GRI), to explore how corporate accountability is being reshaped in a world defined by geopolitical tension, technological disruption, and rising expectations. As the original standard setter for sustainability reporting—emerging from initiatives that followed major environmental crises like Exxon Valdez—GRI has played a central role in defining how companies measure and communicate their impact. But today, the landscape is far more complex. Accountability is no longer limited to environmental damage. It now includes issues such as data privacy, AI, social inequality, governance, and the broader role of business in society. Robin Hodess unpacks how sustainability reporting is evolving from a compliance exercise into a critical source of strategic insight. She explains why businesses must move beyond fragmented frameworks and focus on what truly matters, using data to navigate risk, identify opportunities, and make better decisions. Learn about: From reporting to decision making: Why sustainability data is becoming essential for strategy, risk management, and long-term business growth The expanding scope of accountability: How issues like AI, data centres, nature, and social impact are redefining what companies are responsible for Complexity vs clarity: Why more frameworks and regulation have created confusion and how leaders can focus on what truly matters Materiality in practice: How companies can prioritize the most relevant impacts without being overwhelmed by the breadth of ESG topics Global fragmentation and standards: What rising geopolitical tensions mean for reporting requirements and why harmonisation matters more than ever The business value of transparency: Why 73 percent of studies show a positive link between sustainability reporting and financial performance Leadership and credibility: How companies can rebuild trust by moving beyond claims and focusing on evidence, progress, and accountability About Robin Hodess Robin Hodess is the CEO of the Global Reporting Initiative (GRI), the world’s leading standard setter for sustainability reporting. With a career spanning finance, ethics, and global governance, she has held senior roles at Transparency International and other international organisations. Robin brings a long term perspective on corporate transparency, accountability, and the role of business in addressing global challenges. Under her leadership, GRI continues to shape how companies measure, manage, and communicate their impact in an increasingly complex world.

Sustainable Edge: Human rights as a competitive advantage with Marcos Neto, United Nations Development Programme.

In this episode of Sustainable Edge Host Joachim Nahem , Executive Chairman and Co-Founder at Position Green, sits down with Marcos Neto , Assistant Secretary-General of the United Nations and Director at UNDP, to examine one of the most persistent dilemmas in corporate sustainability: does respecting human rights hurt or help business performance ? As geopolitical tensions rise and regulatory frameworks become more fragmented, many executives are questioning how far their responsibility should extend across global value chains. This conversation explores where accountability really sits today and why the debate around human rights, competitiveness, and transparency is reaching an inflection point for global business. In this episode Marcos Neto unpacks new research from UNDP that directly challenges the assumption that human rights due diligence comes at the expense of financial performance. Drawing on a multi year analysis of more than 200 global companies across sectors including apparel, extractives, automotive, ICT, and agriculture, he shares what the data actually shows and why ignoring human rights can pose a real risk to long term value creation. Learn about: Human rights and financial performance Why companies with stronger human rights practices see higher returns on assets and why declining performance carries measurable financial risk The myth of lost competitiveness What the evidence says about investor reactions, cost concerns, and profitability From policy to decision making Why human rights only matter when embedded into core business processes rather than treated as a reporting exercise Regulation, investors, and accountability How responsibility is shaped not only by law but by stakeholder expectations and risk management Emerging human rights risks What leaders should watch as business models evolve across areas like AI, data centres, critical raw materials, and reshoring Materiality in practice How executives can focus on what truly matters without trying to solve every problem in the world About Marcos Neto Marcos Neto is Assistant Secretary-General of the United Nations and Director at UNDP , where he leads work on private sector engagement, sustainable finance, and governance. With more than three decades of experience across civil society and international institutions, Marcos works at the intersection of business, human rights, climate, and development. He has been closely involved in advancing global standards on disclosure, due diligence, and the integration of sustainability into corporate decision making.
