    Why Nature Credits Matter – With Brian MacSharry, European Environment Agency

    Unpacking how nature credits could reshape the way we value biodiversity and fund its restoration with Dr. Brian MacSharry of the European Environment Agency In this episode of Constructive Voices, Jackie De Burca interviews Dr. Brian MacSharry from the European Environment Agency to discuss the concept of nature credits, their significance in the context of biodiversity, and how they differ from carbon credits. Brian shares insights from his extensive career in environmental policy, emphasising the importance of recognising the role of biodiversity in our economy and society. The conversation explores the challenges of measuring biodiversity, the roadmap for implementing nature credits, and the potential for incentivising private sector involvement in conservation efforts. Brian concludes with actionable steps for individuals and businesses to support biodiversity. What You’ll Learn in This Episode With Dr. Brian MacSharry: The difference between carbon credits and nature credits, and why biodiversity is harder to measure. How businesses and economies are far more dependent on nature than most people realise. Why the European Union’s roadmap for nature credits is both ambitious and full of open questions. How pilot projects across Europe are already testing new models of valuing biodiversity. Practical ways individuals, businesses, and policymakers can support biodiversity today.

    Ireland’s Retrofit Race — with Dr. Ciarán Byrne (SEAI)

    How Ireland is making homes warmer, cheaper to run, and lower-carbon—at real scale—and what you should actually do first. Ireland’s Retrofit Race Ireland set out to decarbonise its housing by upgrading existing homes—insulation first, fossil heating out, heat pumps and other renewables in. Dr. Ciarán Byrne from the Sustainable Energy Authority of Ireland explains what “retrofit” really means, where the numbers stand, what’s working, and how to start your own upgrade without getting overwhelmed. Ireland’s Retrofit Race with Dr. Ciarán Byrne “Anything you do in this space is no-regrets work.” Dr. Ciarán Byrne C Dir Why listen to Ireland’s Retrofit Race Plain-English retrofit 101: What counts, what doesn’t, and why external wall insulation can make a whole street look brand new. Real progress, real targets: Thousands of upgrades each year, with a growing share of homes reaching a strong BER rating. Money + logistics, demystified: Grants that can be netted off your bill, low-cost green loans, and why using registered contractors matters. Old buildings, smart fixes: How “breathable” materials and traditional-home know-how avoid moisture traps in heritage fabric. Myths busted: You usually don’t need to move out for a deep retrofit; confusion often comes from bundling retrofits with kitchen or bathroom refits. Ireland’s Retrofit Race Pilot Projects Under 1 Minute Snippet Chapters (00:00:00) - What is retrofitting? A home-energy upgrade: insulate the fabric (walls, roof, doors, windows), then swap fossil heat for renewable systems like heat pumps.(00:03:00) - Targets & the clock: Carbon budgets arrive in five-year blocks; scaling now matters because the decade is “back-end loaded.”(00:04:30) - Scorecard: Applications and completions climbing, more homes hitting BER B2, and solid momentum behind insulation-first pathways.(00:09:30) - Scorecard: Applications and completions climbing, more homes hitting BER B2, and solid momentum behind insulation-first pathways.(00:16:00) - The homeowner journey: Make action easy; reduce clicks and complexity; balance demand with trained, inspected, registered contractors.(00:20:00) - Grants that actually move: Faster approvals, one-stop shops that can net off aid, and quality assurance through inspections.(00:30:00) - “Isn’t this only for the wealthy?” Attic insulation is often the cheapest, best first step; green finance covers the rest.(00:33:00) - Deep retrofit myths: Staying put vs. moving out—and why people conflate retrofits with other renovations.(00:34:00) - Heritage & physics: Permeable vs. impermeable materials and a growing evidence base for doing old buildings right(00:37:00) - What’s next: Optimised construction, off-site panels, digital twins—promising, but still at early stage locally.(00:40:00) - SEAI’s role: “The meat in the sandwich”—bridging policy and delivery while simplifying, standardising, consolidating.(00:41:00) - 2026 success looks like… Bigger numbers, smoother customer journeys, and a confident supply chain.(00:42:00) - Final advice: Check your BER and advisory report, explore grants/finance, pick registered contractors, and start now.

    David Picton on Safety, Sustainability & the Rise of the Lone Worker

    Safety isn’t a box-tick—it’s a living culture. David Picton shares hard-won lessons from military logistics to boardrooms and major infrastructure projects. We dig into why lone workers are growing fast, how extreme weather is reshaping site risks, and how connecting culture with smart tech turns “compliance” into prevention. You’ll hear real examples—from JLL to Costain—and a pragmatic playbook any firm can use. “Safety works when everyone has permission to call it out—from apprentices to execs.” David Picton What we cover with David Picton 1.  Lone workers: why they’re on the rise, the unique risks they face, and how to protect them. 2. Climate disruption on site: heat, storms, floods—and the simple factors (shade, hydration, acclimatisation, permission to speak up) that change outcomes. 3. Culture that speaks up: the “permission” moment that proves safety works when everyone can challenge—even a junior apprentice. 4. Data into decisions: how visibility lifts reporting and drives action. 5. SME playbook: low-cost, high-impact moves for smaller firms to handle extreme weather and continuity. Courtesy of Ecoonline “Technology plus culture is the shift—from basic compliance to predicting issues before they happen.” David Picton Practical takeaways for daily use Start with risk assessments on your highest-exposure tasks and locations. Keep them live as conditions change. Plan for weather: set clear comms trees, cross-training, and alternative task lists for

    Good News: A New Way To Look At Sustainability & Pocket Forests & Retrofitting in Ireland

    In this uplifting edition of the Constructive Voices Good News podcast in less than six minutes, we bring you a short, sharp burst of positive stories from the built environment — with a dash of conservation inspiration. A New Way To Look at Sustainability: Neurosustainability We open with a fascinating concept that’s as much about protecting our minds as it is about protecting the planet — neurosustainability. Host Jackie De Burca speaks with Mohamed Hesham Khalil, whose pioneering research at the University of Cambridge explores how the built environment affects our brain health, mental wellbeing, and cognitive performance. “That shift… from experiencing the built environment in a specific way and then going back was an alert to start seeing this relationship between the built environment and the human brain.” — Mohamed Hesham Khalil Discover how architecture, neuroscience, and nature intersect — and why this matters more than ever post-lockdown. Greening Ireland: Pocket Forests Next, volunteer reporter Sarah Austin speaks with Catherine Cleary, co-founder of Pocket Forests, about transforming small urban spaces into thriving native woodlands. With over 125 sites planted — from car-parking-space-sized micro-forests to half–tennis-court plots — these dense plantings are changing soil health, biodiversity, and community connections. “We’re planting much younger trees… much more closely together… the result is that they create this microclimate very quickly.” — Catherine Cleary For the full deep dive, check out our special episode Greening Ireland from Pocket Forests to Native Woodlands on our website.
