Science And Sustainability Practices

Methods for Assessing Materiality 🌎 Materiality assessments are a critical foundation for sustainability strategies, ensuring that companies focus on the most relevant issues. Over time, the concept of materiality has expanded beyond financial considerations to include broader social and environmental impacts. Financial materiality focuses on risks and opportunities that affect a company’s financial performance. This perspective is primarily used by investors, lenders, and regulators to evaluate long-term business viability. Frameworks like SASB, IFRS, and TCFD emphasize this approach. Impact materiality considers how a company’s operations affect society and the environment. This perspective is relevant for consumers, employees, communities, and civil society. GRI standards have played a key role in defining and structuring impact materiality assessments. The concept of double materiality integrates both approaches. It recognizes that sustainability issues can be financially material while also having broader social or environmental consequences. This framework is central to the European Sustainability Reporting Standards (ESRS) and emerging regulatory requirements. Materiality assessments help organizations prioritize sustainability topics that align with their business strategy, regulatory obligations, and stakeholder expectations. Identifying the right issues ensures that sustainability initiatives are relevant and impactful. The shift toward double materiality reflects the growing expectation that companies must not only assess financial risks but also measure and disclose their broader sustainability impacts. This approach is shaping corporate decision-making, reporting, and long-term planning. Regulatory frameworks are evolving to incorporate double materiality, making it a key requirement for sustainability disclosures. Organizations that proactively align with these expectations will be better positioned to navigate emerging risks and opportunities. A structured and transparent materiality assessment strengthens corporate sustainability efforts, enhances accountability, and ensures that companies contribute to a more resilient and responsible economy.

We introduce a massive dataset on #ESG transparency and performance and new machine learning framework for extraction in a recently released paper "Assessing Corporate Sustainability with Large Language Models: Evidence from Europe" with Kerstin Forster, Lucas Keil, Victor Wagner, Thorsten Sellhorn, and Stefan Feuerriegel. We apply a large-scale machine learning framework to extract 2.9 million quantitative ESG indicators from the annual and sustainability reports of the 600 largest listed European firms over 2014–2023. Our open-source framework enables systematic, indicator-level tracking of both ESG transparency and performance in line with ESRS standards. 🔍 Key insights: – Firms with top ESG ratings disclose 22% more indicators than bottom rated peers, but this gap is narrowing – Scope 1 & 2 emissions dropped sharply, while scope 3 increased 5.6x, likely due to improved transparency around value chain emissions – Gender equality indicators show progress; other social indicators stagnate – Our open-source dataset and ML pipeline democratize access to ESG data 👉 Read the paper: https://lnkd.in/ezF6Y-dn 📊 Explore the data: https://lnkd.in/eXxcwznT 💾 Download the data: https://osf.io/q2jpv/ 🛠 Code & framework: https://lnkd.in/eEi67_Dg We hope this helps researchers, policymakers, and financial actors monitor and drive progress toward sustainability goals. A key insight from our work is that transparency and performance must be analyzed together as increasing transparency can reveal previously hidden poor ESG performance. While we validate our framework and find high agreement overall, accuracy varies across indicators. The method is likely better suited for analyzing trends across larger samples, not necessarily for high-stakes decisions at the individual firm level, where manual validation or tagged data remain important to ensure precision.

Contemporary African Architecture: Tradition as a Tool for Sustainability A powerful shift is happening across Africa’s built environment where contemporary projects are not replacing tradition, but reinterpreting it to address today’s climate, social, and resource challenges. These projects demonstrate how vernacular massing, spatial rhythms, and courtyard typologies can be paired with modern detailing and durable materials to create architecture that is both culturally rooted and performance-driven. 🔹 Material honesty → prioritizing local, low-embodied energy resources 🔹 Passive cooling → cross-ventilation, thermal mass, deep shading 🔹 Climate-responsive courtyards → cooler microclimates and social space 🔹 Adaptive reuse of local skills & materials → lower cost, higher resilience 🔹 Community-first programming → shared public realms that strengthen social life The result? ✔ Reduced embodied carbon ✔ Lower operational energy demand ✔ Stronger cultural continuity ✔ Scalable lessons for context-driven design For students and practitioners, this is a reminder that sustainability is not a technology add on it is embedded in form, material, and community logic.

🌍 Some companies aren’t waiting for the sustainability playbook to be written—they’re writing it themselves, through real and often difficult business model transformation. This recent Harvard Business Review article by Ivanka Visnjic, Felipe Monteiro, and Michael Tushman spotlights four such firms—Enel Group, Holcim, OCP Group, and Suzano. What they share is not a single blueprint, but a willingness to rethink how value is created, delivered, and measured across their organisations. They’re reshaping innovation portfolios ⚙️, building ambidextrous structures 🔁, and enabling experimentation at the edge 🧪—while keeping an eye on scale and integration. These are practical responses to a complex challenge, not abstract aspirations. One thing the article captures well is the real organisational work involved. Enel set up separate business units to explore new energy services. Holcim created a global programme to empower local plants with data and digital tools. Suzano is investing in community-based initiatives and backing them with budget authority, not just words. OCP’s internal platform, Le Mouvement, is turning employees into active designers of sustainability solutions. All of this takes place while navigating three tough but familiar tensions: 📉 Delivering on short-term performance while building for the long term 🌐 Driving global goals while staying grounded in local realities 🤝 Opening up to external partners while maintaining internal alignment These tensions can’t be eliminated—but they can be managed intentionally. And the companies profiled are showing that it’s possible to do so without losing focus or diluting ambition. For me, the article reinforced a broader point: sustainability, when taken seriously, demands organisational creativity—not just technical fixes or stronger targets. It requires rethinking capabilities, incentives, and learning structures across the organisation. And it often means questioning core assumptions about what business is for, and whose interests it serves. So the questions I’m left with are these: 🔹 Are we preparing our organisations—structurally and culturally—for this kind of transformation? 🔹 And are we willing to confront the uncomfortable trade-offs it inevitably exposes? I’d highly recommend this piece to anyone working at the intersection of strategy, innovation, and sustainability. It’s rich in insight and refreshingly grounded in real organisational practice: https://lnkd.in/dtEqnezP

Crabs in rice fields. Sounds weird, but it's one of the smartest pest management systems I've seen. 🦀 🌾 Here's how it works: Crabs eat weeds and remove pests, while their waste fertilises the rice. This leads to: ✅ Improved yields ✅ Protein for local consumption ✅ Secondary source of income And you need zero pesticides. This is Agroecology in practice: Building biodiversity that does the work chemicals used to do. The principle is super simple: Establish natural predators and allow the ecosystem to control pests while regenerating soil. Food production is currently the largest driver of global biodiversity loss. But it doesn't have to be. When we design systems that work with Nature instead of against it, we get better yields and healthier ecosystems. 🌱 The crabs are just one example. But there are loads of others that are more effective in many other geographies: ✦ Birds controlling insects in orchards ✦ Beneficial insects managing aphids ✦ Cover crops suppressing weeds In all of these stories, the pattern is the same: biodiversity replaces chemicals. And the earth and farmers are better off for it. 🌍

A food company can be organic. Can it be agroecological? Yes! But unlike the clear organic standards & certifications, that assessment requires looking at actions across a range of agroecological principles, similar to the global principles behind organic farming. Tools are emerging for these assessments in organic & agroecological companies (see B-ACT in comment below), and a recent visit to Agroecological Enterprises in Dakar, Senegal gave rich insights into what an Agroecological Enterprise can look like. Participating in the visits were impact investors, donor nations, frontline farmer & civil society organisations, philanthropies and policy makers from 13 African nations. Brought together by the team at Biovision Foundation, we had just emerged from two 2-day workshops on: Scaling Agroecological Entrepreneurship in Africa through Finance and Policy and Advancing National Agroecology Strategies We all converged for dialogue on innovation in financing agroecological enterprises & national policies, and discussed many new initiatives, like The Neycha Accelerator & Fund in Uganda & Kenya (see comment). We visited baby food producer LE LIONCEAU, or the “Lion cub” in Dakar. And what a mighty roar! Lionceau hit numerous agroecological & organic principles spot-on with their actions & approach: ✅Connectivity: Lionceau has a short distribution network “Connecting 3000 farmers to babies,” as CEO Siny Samba put it. ✅Fairness and Participation: Long-term relationships with farmers, improving livelihoods and working through Participatory Guarantee Systems (PGS) and women’s farmer groups, strengthening equity and decentralized governance; as well as hiring many youth. ✅Social Values and diets: Improving healthy, highly diverse diets for babies with high nutrition foods; using no food additives; using 23 local ingredients supporting greater crop diversification, and motivating use of local & indigenous foods. “Microdoses” for very low-income families, and highly nutritious, fiber-rich flours like indigenous Fonio, that, mixed with water, provide cheap healthy baby food. ✅Economic Diversification: Diversifying and improving on-farm incomes by moving the first pre-processing and value addition of crops to the womens farms, and providing equipment; and plans to help farmer groups towards organic certification by 2026. ✅Biodiversity: Lionceau incentivizes farmers to plant (and not cut down!) moringa, baobab & other trees by creating a market for their fruit, increasing agro-biodiversity and climate benefits. ✅Recycling: All glass jars can be returned with a rebate on the next jars. ✅ Soil health: training of farmers in soil health practices Lionceau has as its greatest challenge: economic viability. This will require, among other elements, new capital to expand production, which currently can only meet 30% of orders coming in. “Bootstrapping is good but 6 years of bootstrapping is difficult. We need to enlarge our partnerships." Exactly!

Empowering Artisans Through Sustainable Raw Materials: A Revolutionary Initiative by Craft Village Transforming Natural Waste into Livelihood Opportunities Imagine a world where raw materials for traditional crafts are available at no cost—how significantly would this impact artisans? Craft Village, in its commitment to fostering self-reliance under the Aatmanirbhar Bharat initiative, has pioneered an innovative approach to sustainable craft production. By utilizing natural grasses such as lotus and water hyacinth, this initiative not only empowers artisans but also addresses critical environmental challenges. Harnessing Abundant Natural Resources for Sustainable Craftsmanship India’s lakes and water bodies are increasingly clogged with invasive vegetation like water hyacinth, disrupting ecosystems and affecting freshwater sources. Governments spend crores annually on mechanical cleaning methods, which leave a considerable carbon footprint and generate excessive bio-waste. Recognizing this challenge, Craft Village introduced a sustainable model that repurposes these abundant natural resources into valuable craft materials, thereby reducing environmental damage while revitalizing lost artisanal knowledge. Reviving Traditional Knowledge and Strengthening Artisan Economies Historically, India’s agrarian communities thrived on a circular economy where farm residues were transformed into craft products. This sustainable approach ensured economic stability, facilitated trade through barter systems, and nurtured craftsmanship as a vital part of family enterprises. Craft Village’s intervention is rekindling this tradition by equipping artisans with the knowledge to convert wild grasses and agricultural residues into high-value craft products. Economic and Environmental Impact Raw material costs typically account for 50-60% of an artisan’s total production expenses. By providing access to free natural resources, Craft Village significantly enhances artisans’ earning potential, reduces production costs, and promotes environmentally sustainable practices. This initiative also presents a viable alternative to plastic-based materials, fostering a cleaner and more sustainable future. A Call for Sustainable Policy and Industry Adoption This initiative serves as a model for policymakers, industry leaders, and sustainability advocates to explore innovative solutions that integrate environmental responsibility with economic empowerment. Supporting such initiatives can help scale traditional crafts, preserve heritage skills, and reduce dependency on industrially manufactured materials that contribute to pollution. Craft Village’s interventions underscore the need to rethink raw material accessibility, ensuring that artisans not only sustain their livelihoods but also contribute to a greener planet. By leveraging nature’s abundance, we can create an ecosystem where sustainability and economic growth go hand in hand.

Two Villages, One Lesson: The Power of Communities in Sustaining the Environment What can two villages—separated by geography, culture, and history—teach us about sustainability? At first glance, very little. One is a medieval English village nestled in the Cotswolds. The other is a tribal village hidden in the hills of Meghalaya. Yet both offer perhaps the most powerful lesson for our climate-challenged world: “Environmental sustainability begins with communities—not policies alone.” Castle Combe, often called the "Prettiest Village in England," has preserved its natural and architectural heritage for centuries through strict conservation rules, responsible tourism, and community stewardship. Its timeless charm shows how communities can preserve heritage while embracing sustainability. Mawlynnong, known as "Asia's Cleanest Village," demonstrates how indigenous wisdom and collective responsibility can create an ecosystem where cleanliness is not a campaign—but a culture. The village is a global example of how local traditions can drive sustainable living. The real story is not about clean streets or beautiful landscapes. It is about people. ❖ In Castle Combe, residents, local councils, and preservation bodies work together to safeguard heritage and manage tourism responsibly—ensuring that economic prosperity does not come at the expense of ecological balance or cultural identity. Their experience highlights the power of community stewardship in preserving both heritage and nature. ❖ In Mawlynnong, environmental stewardship begins at home. Children learn that cleanliness is a shared responsibility, while waste segregation, limited plastic use, and community participation make sustainability a way of life. The village shows how environmental consciousness is most effective when nurtured from a young age. Both villages reveal an important ESG truth: Sustainability is strongest when communities become custodians of their environment rather than mere beneficiaries of it. In an era of climate change, urban pollution, and resource stress, these villages remind us that lasting environmental change does not always require billion-dollar investments or sophisticated technologies. Often, the most effective solutions emerge from collective action and shared values. Sometimes, it begins with: ❖ Shared responsibility ❖ Cultural values ❖ Local governance ❖ Intergenerational learning The future of sustainability may not lie only in smart cities and advanced technologies. It may lie in communities that have quietly practised sustainable living for generations. As policymakers, businesses, and societies seek pathways toward a more sustainable future, the experiences of Castle Combe and Mawlynnong offer a simple yet profound lesson: when communities care, ecosystems thrive.

Can we compare CSRD reports? 💡📑 One of the big promises of standardized sustainability reporting is that it will make comparing the sustainability performance of companies possible—both within and across sectors. But is that really the case? Or are we still comparing apples and oranges? 🍏🍊 Now that we have dozens of fully ESRS-compliant reports, I set out to compare the ESG performance of three commercial banks: Danske Bank, SparNord, and Ringkjøbing Landbobank A/S. To spice things up, I used ChatGPT 🤖 to assist in the analysis and test the extent to which LLMs can help with this task (of course, I fact-checked the results 📌). Many argue that digital tagging won't be necessary in the AI era—but does that hold up? Here’s what I found: 🚀 Comparing DMA processes is harder than expected: Even though Danske Bank and Spar Nord provided unusually detailed descriptions of their double materiality assessment (DMA) processes, the boundaries of their analysis remain fuzzy. The extent to which they consider indirect impacts (which is crucial for banks) varies significantly. 💾 AI's strength lies in analyzing the quality and extent of disclosures: - The more data a company provides, the better its sustainability performance appears. For example, missing financed emissions data translates into a lower assumed sustainability score. - This inherently penalizes smaller or less mature institutions, which are still in the early stages of their ESG data collection and control journey. - When I asked ChatGPT to compare the three banks' sustainability performance, Danske Bank emerged as the clear winner 🏆—not necessarily because they are the most sustainable, but because they report extensively on their material topics, supported by a wealth of data. 📉 Comparing Scope 3 emissions (and total GHG footprint) is nearly impossible: - Each bank uses slightly different methodologies, and their maturity levels in collecting high-quality data vary significantly. - This makes a direct GHG emissions comparison unreliable, even when companies report in line with ESRS. 📖 Narrative disclosures present another challenge: - AI—and likely most users of sustainability reports—focus on checking the existence of policies, actions, and targets 📌 rather than analyzing their actual substance and effectiveness. - This highlights a critical gap in sustainability reporting: standardization alone doesn’t necessarily mean comparability. 💡 Final thought: While ESRS is a huge step forward in sustainability reporting, we’re not yet at the stage where comparing CSRD reports is seamless—especially for financial institutions. Until methodologies are further harmonized, AI, digital tagging, and human expertise will all have a role to play in making sustainability data truly comparable. 👉 For more insights, join our webinar (link in the comments)

WHEN ACCESS BECOMES SUSTAINABILITY Across parts of Germany and other European cities, a quiet shift is redefining how societies think about clothing waste and dignity. Instead of rigid donation systems or hidden charity processes, some communities are installing open clothing stations—simple public racks or bins where people can leave what they no longer need and take what they do. No forms. No judgment. No barriers. What makes this model powerful is not just the clothes—it’s the philosophy behind it. Traditional systems often separate “giver” and “receiver.” These shared clothing spaces blur that line completely. A student may leave a jacket in the morning and pick up a sweater in winter. A worker may donate shoes and later find a replacement when needed. The system works on trust, not transaction. From a sustainability lens, the impact is equally significant: Extends product life cycles Reduces textile waste in landfills Lowers demand for fast fashion production Encourages circular consumption habits at the community level But beyond environmental benefits, there is something deeper happening here: dignity in access. When clothing becomes publicly available without labels of “charity” or “aid,” the stigma often attached to need begins to fade. It raises an important question for urban sustainability: Can circular systems succeed not only through technology and policy, but through radical simplicity and trust? The answer emerging from these initiatives is quietly encouraging: yes. Because sometimes sustainability is not about building more complex systems—it’s about removing unnecessary gates between people and resources. #Sustainability #CircularEconomy #WasteReduction #SocialInnovation #ClimateAction #TextileWaste #CommunityDesign
