The GreenWave Podcast

SYNI, your hostess with plenty of gusto, launches into our Year End 2025 episode, reflecting on the three topics that most defined sustainable energy and development trends as we move into the New Year. Before we get into the substance, a quick note of appreciation. This year marks our first full year of podcasting, which in podcast terms is roughly the same as surviving a full year of budget seas...

SYNI, your host brimming over with Christmas spirit, offers a short holiday message, plus a quick look at what we have been unpacking together this year across our first 51 episodes. And rest assured, we’ll be back with our year-end 2025 episode next week, reflecting on developments both good and bad for sustainability during this year. So Merry Christmas and Happy Holidays to everyone listening i...

SYNI, your hostess with real panache, addresses the European Union’s Carbon Border Adjustment Mechanism, better known as CBAM, and why at the start of 2026 it will become the most important piece of climate policy that many exporters will only notice when an EU customer emails them with the subject line “Urgent Emissions Data Request.” Once again, the EU has followed the courage of their convictio...

SYNI, your hostess, turns her curiousity to the sustainability story behind big wave surfing contests, with a special focus on the World Surf League TUDOR Nazare Big Wave Challenge and what it means for the Blue Economy and for ocean conservation. The surfing community is officially on watch between now and March for “gigantes” to roll into Nazare, then the klaxon will blow for the start of the 20...

SYNI, your ever-loyal pod hostess, turns her focus to AI, data centres and an impending power crunch in this new “Age of Electricity.” Can electricity grids manage to stay green amid booming AI demand for power? Forecasted data centre electricity demand will soon begin to outstrip sustainable supply. And this unbalance is forecast to grow quickly and become unmanageable in the not-so-distant futur...

SYNI, your hostess that defines podcasting elegance and focus, addresses the events of this week all pointing to being confidently wrong in a wetter world. No prizes for all of us that knew COP30 was always likely to be a bust. SYNI provides a brief discussion of this latest edition of a COP flop, the briefer the better. Yet the political clownshow in Belém dovetails with some extraordinary news a...

SYNI, your hostess that consistently exceeds expectations, asks if adaptation and resilience are now the fallback positions due to an expected failure to deliver on Net Zero? Are we quietly shifting from a world where mitigation reducing emissions is the main story to a world where we accept higher levels of warming and simply try to toughen up our societies and our infrastructure? This is not jus...

Instead of yet another COP30 preview, your hostess SYNI heads right into the heart of the real sustainable energy debate that is sadly missing in Brazil, starting with an explanation of the one chart you need during COP30 week, the classic Sankey energy use diagram. If you’re not familiar with the Sankey, never fear, you will be by the end of this pod. And you’ll know how it reveals that clean ene...

SYNI, your hostess with virtual swag, challenges us to become time travellers to ameliorate our view on climate change. She addresses the recent, growing clamour in the climate change debate and why the science leaves very little room for doubt. The clock we should be watching is measured in geological time rather than in financial quarters or electoral cycles. Claims that urgent action is alarmis...

SYNI, your host with the most subtle-swag in the sustainable community, is focused on the United Nations endorsing the first Article 6.4 carbon credit methodology, a breakthrough that may unlock hundreds of billions $$ in climate finance and reframe how global carbon markets operate. SNYI introduces you to the A6.4ER (catchy we know!) and unravels why this huge step forward that has taken a decade...

SYNI, your host, gives a review of the International Maritime Organisation meeting in London last week to promote a Net Zero agenda. Spoiler Alert: Delegates arrived with dense documents and finely tuned talking points and left with a familiar souvenir from multilateral life. The headline is simple. The can has been kicked into 2026. The decision on a global fuel standard and a pricing instrument...

In this episode, SYNI, your host who provides the most, is mulling the politicisation of sustainability, especially sustainable finance at the supranational institutional level. The World Bank sits at this crossroads, and there are political opponents howling in the not-so far distance. This brings us to a core principle we have stated since the start: sustainability should stand on its own, not b...

Join SYNI, your host, for an examination of Germany’s role in Europe’s green hydrogen industry and the politics now shaping support for production and infrastructure across the Union. Germany likes to think of itself as Europe’s industrial metronome. When the beat is steady, factories hum and policy lines up with engineering. When the beat stutters, everyone hears it. Nowhere is that more evident...

SYNI, your host, explores the Douro Valley as a living landscape, a place that invites careful stewardship because it is both a working valley and a world treasure. We are going to explore how UNESCO helps set a sustainable framework for this remarkable region in northern Portugal, how local institutions and producers have translated that framework into practical choices, and why the Douro remains...

SYNI, your host, delves into New York City Climate Week, one of the high-profile gatherings on the sustainable calendar. As the conference moves into full-swing, we want to answer two important questions that you may share. Is this spectacle or substance? Are we meeting to admire the problem or to move capital and policy and technology at the speed required? SYNI works through these animating ques...

SYNI, your hostess, address today’s topic of a slightly specialist nature within the world of sustainable politics, Nationally Determined Contributions, otherwise known as NDCs, and whether they are a credible foundation of climate action or a theatrical flourish of sustainable politics that promises the earth on the grand political stage but then forgets its lines once the global attention and au...

In our 37th Episode, SYNI, your host, tackles the next wave of sustainable energy storage and why it will define the pace and reach of the clean power transition. Storage is the hinge on which an electrified future swings. Solar and wind now form a meaningful and growing share of generation in many markets. Yet scale brings new questions. SYNI asks you, our loyal listeners, to picture the grid as...

SYNI, your indefatigable hostess, focuses on the Science Based Targets initiative and its draft revision to the Corporate Net Zero Standard, which were recently updated. We hope you didn’t think we would go for a light and cheerful topic to close out the summer? No, no! Instead SYNI plunges into the deep end of sustainable governance and corporate regulation, taking a close look at STBi Version 2....

SYNI, your host, tears into today's topic, the European Union Hydrogen Bank. Specifically, what is wrong with the Bank and why are winners of the biggest subsidies walking away from completing their green hydrogen projects? We’re talking about three of the largest green hydrogen projects in the EU turning an icy shoulder €589 million of future EU support during this blazing hot summer. We’ll need...

This week join SYNI, your host, as she dives into the role of crypto currencies in sustainability with a special look at the growing role of tokenisation in carbon credits. It’s been a subject on our radar for several weeks, and with the growing mania over bitcoin’s rapid price rise in recent weeks, it’s seems like the perfect time to tackle the subject of how the explosive world of digital curren...

Your host SYNI explores the European Union’s latest push to harness artificial intelligence in the energy sector as a tool against climate change. The EU has recently opened consultations for a Strategic Roadmap on Digitalisation and AI in the Energy Sector, reflecting its commitment to ensure the digital and green transitions go hand-in-hand. We’ll explore how AI can accelerate decarbonisation ac...

SYNI, your hostess with dry wit and a sharp tongue, launches into the second in our Summer mini-pod series, well aware that many of you might currently be lounging beachside, mountain-bound, hiking on the South Rim of the Grand Canyon, or spending the long August days on your island in the Baltic Sea, not exactly keeping pace with the latest in climate finance literature. So allow SYNI to bring yo...

SYNI launches our summer series of mini pods, shorter more focused episodes intended to match the shorter attention spans of our summertime listeners. Today’s topic is the High-Level Political Forum on Sustainable Development, better known to its friends as the HLPF. Specifically, we’re diving into the launch of the Climate and SDG Synergy Solutions reports and the wider signals sent at this year’...

SYNI is riding the breeze for today’s pod topic of sailing – its heritage as a sustainable means of transport and sailing’s place in today’s world of sustainable sport and pastimes. As the saying goes, we cannot direct the wind, but we can adjust our sails. The sailing world is doing exactly that, adapting its practices to protect what it loves. In the process, it keeps alive the spirit of explora...

SYNI launches into Part 2 of our mini-series on the European Commission’s proposed 2040 Climate Law amendment, a plan that would legally bind the European Union to cut its net greenhouse gas emissions by 90% by the year 2040. This week we’re zooming in on the Iberian Peninsula, unlocking the likely impact of the EU’s initiative specifically on Spain and Portugal, and then circling back to the trad...
