  • Advancing Biobased Technologies in the Bioeconomy

    Advancing Biobased Technologies in the Bioeconomy
    Oct 9 2025
    This episode looks at the concept of the bioeconomy and its potential to contribute to climate change mitigation and adaptation

    It examines the progress being made in scaling up the availability and use of these technologies, highlighting both global trends and region-specific developments.

    Biobased technologies include processes, products and systems derived from renewable biological resources such as biomass, agricultural residues and algae that can be sustainably replenished over time.

    Accelerating technological innovation and policy momentum is driving growth in biomass utilization and biogenic carbon solutions, sustainable land use and advanced biobased materials.

    The global bioeconomy is valued at an estimated $4–5 trillion, with the potential to grow to $30 trillion by 2050, positioning it as a cornerstone of the transition to a low-carbon, climate-resilient, and sustainable future.

    Realizing this potential will require targeted action across technology, finance, and effective governance and policy.

    Join Daya Pandey, Francis X Johnson, Alex Godoy-Faundez and Debora Ley, lead authors of the 2025 Climate Technology Progress Report in a broad discussion of the bioeconomy.

  • Clean Cooking - Financing, Policy, and Innovation for Last Mile Impact

    Clean Cooking - Financing, Policy, and Innovation for Last Mile Impact
    Jul 18 2025
    In this episode of the ClimateTech Podcast, we explore how clean cooking—especially electric cooking powered by renewables—is emerging as a powerful climate solution with wide-reaching benefits for health, gender equality, and sustainable development.

    We delve into why clean cooking is now a national priority in Uganda, the numerous co-benefits, barriers to scale, including affordability, access, and awareness, and how carbon markets and Article 6 of the Paris Agreement can unlock new financing pathways.

    Guests:
    • Herbert Abigaba, Head of the Clean Cooking Unit, Ministry of Energy, Uganda
    • Ruth Akiiki Komuntale, Managing Director, ECOCA East Africa
    • Ben Jeffreys, Managing Director, ATEC
    • Sandra Cavalieri, Clean Cooking Lead, Climate and Clean Air Coalition (CCAC)
    For more insights, check out the report Business and Financing Models for PV-Supported Clean Cooking.

    Or check out the SOLCO Partnership - a multi-stakeholder ecosystem catalyzing the transition to solar-powered electric cooking or hybrid e-cooking in last mile communities across the globe, and the Global Electric Cooking Coalition (GeCCo) - a collaboration of eCooking advocates seeking to significantly scale up access to electric cooking solutions across the world.

  • Unlocking the potential of biogas

    Unlocking the potential of biogas
    Jul 4 2025
    In this episode of the ClimateTech Podcast, we explore the untapped potential of biogas as a renewable energy solution— looking at experiences from Brazil and research from Africa. From household systems to industrial-scale applications, biogas offers a powerful way to reduce emissions, improve waste management, and support energy access.

    Guests:
    • Yuri Schmitke, President of the Brazilian Association of Waste Energy Recovery (ABREN), who shares insights from Brazil’s national biogas strategy and upcoming biomethane mandate.
    • Dr. Solomon Eghosa Uhunamure, postdoctoral fellow at the University of Cape Town, who brings a research-based perspective on biogas adoption in South Africa.
    This episode is produced through the Smart Energy Solutions for Africa (SESA) project, funded by the European Union.

  • Breaking barriers: Scaling urban nature-based solutions in South Asia and Latin America

    Breaking barriers: Scaling urban nature-based solutions in South Asia and Latin America
    Apr 25 2025
    In this episode, we look at nature-based solutions and how we can overcome the barriers to scale and implement them in growing cities. The guests present several societal and biodiversity co-benefits resulting implementing nature-based solutions for climate adaptation and resilience in cities. We delve into policies, regulations, and the need for enhanced capacity and peer-to-peer knowledge transfer between cities of the global south.

    Guests:
    • Julia Rocha Romero, Advisor – Nature-based Solutions, UNEP-CCC
    • Gabriel Dias Mangolini Neves, Environmental Engineer, Municipality of Campinas, Brazil
    • Monalisa Sen, Associate Director, ICLEI – Local Governments for Sustainability, South Asia

  • The Adaptation Finance Gap - Beyond the numbers

    The Adaptation Finance Gap - Beyond the numbers
    Nov 2 2023
    In this episode, we talk about the Adaptation Gap, more specifically the adaptation finance gap.

    Joined by the authors of the finance chapter of UNEPs 2023 Adaptation Gap Report, we delve into the big numbers, go beyond them, and try to show what the adaptation finance gap actually means and what we can do about it.

    The report shows an adaptation finance gap of 194 to 366 billion dollars - numbers that can seem almost surreal.

    But, bridging the adaptation gap is not just about reaching the right amount of billions in finance, its also about how we spend the money, about equity, and about gender and social inclusion aspects.

    As the report and the guests make clear, emissions reductions are urgently needed. Slow and insufficient climate adaptation is stretching the limits of our ability to cope with climate change, increasing loss and damage in the future.

    Guests:
    • Paul Watkiss, Director of the research consultancy Paul Watkiss Associates
    • Dipesh Chapagain, Senior Research Associate at the United Nations University Institute for Environment and Human Security.
    • Georgia Savvidou, research associate at Stockholm Environment Institute and PhD researcher at Chalmers University of Technology.
    • Blanche Butera, climate adaptation specialist at Paul Watkiss Associates. Based in Rwanda
    • Pieter Pauw, senior researcher at the Eindhoven University of Technology
