As London Climate Action Week gets into full swing, we break down the key talking points from the conference so far. With the city in the midst of a scorching heat wave, the discussion of climate change feels even more urgent than usual. We explore the transactional landscape that developing nations face, where much-needed capital is increasingly tied to the private sector. Beyond the balance sheets, one of the current tensions is the collision between green ambitions and economic survival. From the push for rapid electrification to the rollout of Europe’s Carbon Border Adjustment Mechanism, African nations are being forced to thread a near-impossible needle: industrializing their economies while navigating low-carbon mandates. Complicating matters is a growing communications crisis within the sector itself. To secure funding and dodge political blowback, many NGOs are camouflaging their climate work under the banners of health, food, or energy security. However, driving the climate conversation underground risks leaving the communities most vulnerable to extreme weather out of the spotlight when they need it most. To bring you the latest from London Climate Action Week, Devex Business Editor David Ainsworth sits down with global development reporters Ayenat Mersie and Jesse Chase-Lubitz for the latest episode of our weekly podcast series. Against a backdrop of record-breaking heat in Europe and growing political pressure to slow climate ambition, Marcene Mitchell, senior vice president of climate change at WWF USA, joins Devex Executive Editor and Executive Vice President Kate Warren to make the case for staying the course. Marcene challenges the “small drop” argument — the idea that individual countries acting on climate don’t matter — and reframes clean energy and nature-based solutions not as a cost, but as an economic and strategic imperative. She breaks down how electrification and the AI-era’s energy demand can be decoupled from fossil fuels, why energy security is itself a climate argument, and what WWF USA — an organization most people associate with conservation — is quietly doing on climate finance and supply chains around the world. Learn how WWF USA is working globally to turn climate ambition into investable pipelines, and why the solutions to get there already exist.

Development economist William Easterly famously does not mince words about the disappointments of anti-poverty megaprojects and far-fetched foreign aid plans. For much of his career, Easterly has taken aim at experts who export their visions onto other people’s countries and communities — drawing from his own experience as one of those very experts. In his latest book, “Violent Saviors: The West’s Conquest of the Rest,” Easterly unearths the long history of what he calls “the development right of conquest,” a worldview that has sacrificed individual rights and agency at the altar of material gain. He traces the long-standing tension between those who pushed for development at all costs and the dissenting voices who resisted them. In the fourth episode of Theory of Change, Easterly unpacks the implications of that history for contemporary development efforts. He reflects on what alternative approaches to improving human well-being might look like — and what role aid institutions should play in pursuing them. “There’s this technocratic illusion that you can reduce development to just technology and effectiveness of achieving measurable gains and these technical indicators of well-being,” he tells Devex Senior Reporter Michael Igoe. “I think we all realize deep down the fantasy of keeping things purely technocratic is really a fantasy, that there really is a whole other dimension,” Easterly says.

In our landmark 150th episode, we discuss a common theme in global development over the past 18 months: the state of U.S. foreign aid. We’re seeing the State Department steadily replenish its workforce, with dozens of open roles across the agency’s global health, international aid, and disaster response bureaus. On the topic of U.S. foreign assistance, last week Secretary of State Marco Rubio claimed the U.S. remains the world's top aid provider "by far" despite the closure of the U.S. Agency for International Development. While provisional figures from the Organisation for Economic Co-operation and Development indicate that Germany has officially overtaken the U.S. for the top spot, we find that the reality is more complex as the validity of the claim hinges entirely on how "aid" is defined. We break down the data and the nuance behind the figures. To discuss these stories, and others, Senior Editor Rumbi Chakamba sits down with Business Editor David Ainsworth and Global Development Reporter Elissa Miolene for episode number 150 of our weekly podcast series.

U.S. foreign aid is undergoing one of the most tumultuous transformations in its history. The Department of Government Efficiency’s dismantling of USAID and transfer of its remaining programs to the State Department upended the U.S. global development industry. But it’s much more than a question of organizational charts and institutional responsibilities. At stake are fundamental questions about America’s national interests, how the well-being of people in other countries should influence economic and trade policy, and the nature of public support for a long-term vision of development investment. Gayle Smith has faced those questions from a variety of vantage points — senior director for development and democracy on the White House National Security Council, USAID administrator, CEO of the ONE Campaign. In this episode of Theory of Change, she shares a candid assessment of where the fight for U.S. leadership in global development should go from here — and who should lead the charge.

At this year’s annual meeting of the European Bank for Reconstruction and Development in Riga, Latvia, discussions centered on a critical structural shift: what development finance should look like in an age of persistent volatility. Ukraine is increasingly shaping the answer, as the bank’s sustained financing during the war emerges as a potential blueprint for future conflicts. We were also on the ground for the World Bank Fragility Forum, an event uniting global stakeholders to address the challenges of operating in areas experiencing fragility, conflict, and violence. The deteriorating situation in the Democratic Republic of Congo emerged as a central discussion point. Highlighting the complexity of aid delivery in active conflict zones, the governor of the DRC’s South Kivu province issued a stark call to withhold funding for development projects until baseline peace and stability are secured. Examining the Trump administration’s “America First” foreign policy, we also contemplate how to ensure that domestic resource mobilization becomes an effective way to increase development finance. To dig into these stories and others, Senior Editor Rumbi Chakamba sits down with Managing Editor Anna Gawel and Global Development Reporter Jesse Chase-Lubitz for the latest episode of our weekly podcast series.

Much of Seth Berkley's career has been an attempt to answer the question: How do you get vaccines to people who aren’t well-served by an inequitable global health system? When the COVID-19 outbreak exploded in early 2020, that question took on new urgency — along with a mind-spinning slew of political, economic, technological, and cultural complications. Berkley, then the CEO of Gavi, the Vaccine Alliance, had a pretty good idea what was coming. As early as February 2020 he was warning publicly that if researchers were successful in developing a COVID-19 vaccine, lower-income countries would struggle to access them. That is exactly what happened. It is also what led Berkley to help launch COVAX, the global initiative to deliver COVID-19 vaccines around the world. In the wake of the pandemic, the relationships between politics, society, and vaccines have only grown more fraught. One example: Secretary of Health and Human Services Secretary Robert F. Kennedy Jr. has personally intervened to block U.S. funding to Gavi. Berkley, a physician and infectious disease epidemiologist, joined Devex’s Theory of Change podcast to discuss the lessons of the COVID-19 response, the long and complicated history of humanity’s relationships with vaccines, the incredible potential of new technologies — and the deeply troubling risks that some of them pose. His new book is called “Fair Doses: An Insider's Story of the Pandemic and the Global Fight for Vaccine Equity.”

This week, we unpack the latest on the Ebola outbreak in the Democratic Republic of Congo and Uganda. With no approved vaccines or treatments for the Bundibugyo species driving the spread, we dive into the race to develop a vaccine and the critical funding shortfalls standing in the way. While pledges have been made, much of that support has yet to reach those affected on the ground. We also discuss the congressional hearings on Trump’s fiscal year 2027 foreign affairs budget request, which featured a debate on the Ebola crisis. With this being the first outbreak since the dismantling of USAID, we break down the United States’ approach to the health emergency. To dig into these stories and others, Business Editor David Ainsworth sits down with Senior Reporters Sara Jerving and Michael Igoe for the latest episode of our weekly podcast series.

Coefficient Giving, one of the world’s largest effective-giving funders, is about to go even bigger. On the heels of its biggest funding year ever in 2025 — in which it channeled over $1 billion to highest-impact causes — the organization formerly known as Open Philanthropy and funded by Facebook cofounder Dustin Moskovitz and his wife Cari Tuna is eyeing annual growth upward of 50% and bringing on more staff to get it done. The person behind that vision is Alexander Berger, Coefficient Giving’s cofounder and CEO. Berger is in charge of turning Facebook wealth — and, increasingly, funds from other donors — into as many lives saved and improved as possible. The organization is a major funder in global health and development, catastrophic risk, research and innovation, and even farm animal welfare. Last week, Coefficient Giving launched a new pooled fund to tackle Group A Streptococcus — an easily treated disease that is still responsible for nearly 700,000 deaths a year — a cause that reflects the organization’s framework for tackling problems that are important, neglected, and tractable. In a rare, in-depth interview with Devex Senior Reporter Michael Igoe, Berger sheds light on Coefficient Giving’s rapid growth plans, its strategy for choosing high-impact causes, the rise of artificial intelligence philanthropy, and his own approach to affecting change in an uncertain world. This is the first episode of Theory of Change, a new podcast series from Devex featuring candid interviews with leaders shaping the future of global development.

In this episode, we look back at the conferences we reported from over the past few weeks, reflecting on how global development narratives are evolving across both the global north and the global south. With traditional donors stepping back, the African Development Bank is using its annual meetings to urge governments to fix tax inefficiencies and better mobilize domestic resources to drive sustainable economic development. We found similar themes at the OECD’s Future of Development Co-Operation conference in Paris and the Global Partnerships Conference in London, where unlocking private capital and prioritizing country-led development emerged as key talking points. To analyze these trends, Senior Reporter Adva Saldinger sits down with Business Editor David Ainsworth and Global Development Reporter Ayenat Mersie for the latest episode of our weekly podcast series.

Filmed live from Geneva, Switzerland, on the sidelines of the World Health Assembly, this episode of This Week in Global Development delves into the critical debates unfolding on the ground in Geneva. That includes the tense atmosphere following the World Health Organization’s rare decision to proclaim a global health emergency over the latest Ebola outbreak, mounting fears regarding the virus tracking into dense urban centers, and how containment efforts are hindered by strict funding restrictions that leave the vast majority of voluntary budgets tied up. The discussion also looks at the highly anticipated — yet heavily criticized — joint strategy to reform global health infrastructure, capturing the frustration of analysts who feel the plan avoids essential conversations about institutional mergers. The behind-the-scenes maneuvering for the next WHO director-general selection enters the conversation as well, along with the complex legislative hurdles facing the African Medicines Agency as it strives to secure pharmaceutical independence across the continent.
