Environmental Engineering Impact Studies

We’re planting trees — but losing biodiversity. Global efforts to restore forests are gathering pace, driven by promises of combating climate change, conserving biodiversity, and improving livelihoods. Yet a recent paper published in Nature Reviews Biodiversity warns that the biodiversity gains from these initiatives are often overstated — and sometimes absent altogether. Forest restoration is at the heart of Target 2 of the Kunming-Montreal Global Biodiversity Framework, which aims to place 30% of degraded ecosystems under effective restoration by 2030. But the gap between ambition and outcome is wide. "Biodiversity will remain a vague buzzword rather than an actual outcome" unless projects explicitly prioritize it, the authors caution. Restoration has typically prioritized utilitarian goals such as timber production, carbon sequestration, or erosion control. This bias is reflected in the widespread use of monoculture plantations or low-diversity agroforests. Nearly half of the Bonn Challenge’s forest commitments consist of commercial plantations of exotic species — a trend that risks undermining biodiversity rather than enhancing it. Scientific evidence shows that restoring biodiversity requires more than planting trees. Methods like natural regeneration — allowing forests to recover on their own — can often yield superior biodiversity outcomes, though they face social and economic barriers. By contrast, planting a few fast-growing species may sequester carbon quickly but offers little for threatened plants and animals. Biodiversity recovery is influenced by many factors: the intensity of prior land use, the surrounding landscape, and the species chosen for restoration. Recovery is slow — often measured in decades — and tends to lag for rare and specialist species. Alarmingly, most projects stop monitoring after just a few years, long before ecosystems stabilize. However, the authors say there are reasons for optimism. Biodiversity markets, including emerging biodiversity credit schemes and carbon credits with biodiversity safeguards, could mobilize new financing. Meanwhile, technologies like environmental DNA sampling, bioacoustics, and remote sensing promise to improve monitoring at scale. To turn good intentions into reality, the paper argues, projects must define explicit biodiversity goals, select suitable methods, and commit to long-term monitoring. Social equity must also be central. "Improving biodiversity outcomes of forest restoration… could contribute to mitigating power asymmetries and inequalities," the authors write, citing examples from Madagascar and Brazil. If designed well, forest restoration could help address the twin crises of biodiversity loss and climate change. But without a deliberate shift, billions of dollars risk being spent on projects that plant trees — and little else. 🔬 Brancalion et al (2025): https://lnkd.in/gG6X36WP

I am thrilled to share our new global dataset on the drivers of forest loss at 1 km resolution, which has been 2+ years in the making! We developed the data using a customized ResNet model trained on a set of samples we collected through visual interpretation of very high-resolution satellite imagery. The model used satellite imagery (Landsat & Sentinel-2) and ancillary data to classify seven driver categories: permanent agriculture, hard commodities (e.g. mining and energy infrastructure), shifting cultivation, logging, wildfires, settlements and infrastructure, and other natural disturbances. This data provides important insights on where tree cover loss is likely to be associated with long-term land use change versus temporary disturbances that may followed by forest regrowth, and can enable targeted solutions to protect and sustainably manage the world's forests. 👉 Read more from our paper, published today in Environmental Research Letters: https://lnkd.in/gxV34-3W 👉 Read a summary of the findings (updated to 2024) here: https://lnkd.in/gghcyVzx 👉 Read our technical blog on GFW here: https://lnkd.in/gBv5ErKU The data is available on: 🌎 Google Earth Engine: https://lnkd.in/gt4t9zhp 🌏 World Resources Institute's Data Explorer: https://lnkd.in/gbVMUzpx 🌍 Global Forest Watch: https://gfw.global/2LUOmIx 🌍 Zenodo (including training + val data): https://lnkd.in/gsn-J9gg I am super proud of this effort and of our team!

Sustainable Development in Action: A Lesson from Japan 🇯🇵 In an era where urban expansion often comes at the cost of nature, Japan offers an inspiring alternative—relocating trees instead of cutting them down to make way for infrastructure. This approach reflects a deep respect for the environment and showcases how technological advancements can align with ecological conservation. As a sustainability professional working in renewable energy, ESG, and environmental impact assessment, I believe this practice serves as a powerful reminder: Development and sustainability can go hand in hand. Instead of choosing between progress and preservation, we must innovate solutions that integrate both. 🌍 Key Takeaways: ✔️ Sustainable Infrastructure – Development shouldn’t come at the cost of green cover. ✔️ Carbon Sequestration Matters – Mature trees play a crucial role in absorbing CO₂. ✔️ Holistic Urban Planning – Cities must incorporate environmental conservation in their growth models. Can we implement similar practices in India and other countries? With the right policies, technological support, and mindset, we can prioritize nature-positive development. Let’s build a greener future, where progress nurtures the planet instead of harming it. #Sustainability #ESG #RenewableEnergy #UrbanPlanning #EnvironmentalConservation #EnergyTransition

A big status update report from EFRAG on the ESRS! What does it show? Right now only 55% of companies reporting under CSRD say they have a climate transition plan. Fewer than half include Scope 3 emissions. EFRAG’s new State of Play 2025 report gives us the clearest picture yet of how “wave 1” companies are implementing the European Sustainability Reporting Standards (ESRS). Here are five things that stood out in our analysis: 1. Climate plans remain incomplete. 70% of firms commit to 1.5°C targets for Scope 1 & 2 emissions—but just 40% extend that ambition to Scope 3. Only 55% disclose a transition plan at all, and most omit key elements such as funding or levers. 2. Materiality is concentrated. Just three topical standards: Climate Change (E1), Own Workforce (S1), and Business Conduct (G1) are considered material by over 90% of companies. Fewer than 10% identified all 10 topical standards as material. 3. Internal carbon pricing remains rare. Only 20% of companies report using an internal carbon price. Uptake is highest in carbon-intensive sectors like mining and electricity, and lowest in services and finance. 4. Biodiversity remains under-reported. Fewer than 30% of preparers include biodiversity metrics. Even when they do, disclosures average just four metrics, often lacking clear connections to targets or outcomes. 5. Stakeholder engagement remains narrow. While 97% engage employees in their double materiality assessment, fewer than one-third consult communities or civil society. Broader societal voices are still marginal in many DMA processes. There’s a lot more detail in the full EFRAG report including examples of good practice and insights into sectoral differences.

Denmark has announced it will plant 1 billion trees and convert 10% of its farmland into forests and natural habitats over the next two decades. With a budget of 43 billion kroner / $6.1 billion, the country aims to reduce fertiliser usage, restore low-lying, climate-vulnerable soils, and expand forested areas by 250,000 hectares. This represents the most significant transformation of the Danish landscape in over a century, with numerous economic and environmental benefits. What are the economic benefits? 1. Job Creation: Large-scale reforestation and land restoration projects will generate employment opportunities in sectors like forestry, environmental management, and sustainable agriculture. 2. Sustainable Agriculture: Reducing fertilizer usage promotes environmentally friendly farming practices, which can lower long-term costs for farmers and mitigate environmental degradation. 3. Climate Resilience: Expanded forested areas act as carbon sinks, reducing climate change impacts. Restoring ecosystems can stabilize agricultural yields and decrease the economic toll of climate-related disasters. 4. Biodiversity and Ecosystem Services: Restored habitats improve biodiversity, which enhances essential ecosystem services such as pollination and water purification, benefiting various economic sectors. 5. Tourism and Recreation: New natural landscapes can boost eco-tourism and recreational activities, contributing to local and national economies. What is the impact of reducing farmland on the economy? Denmark’s decision to reduce farmland is a calculated step toward sustainability, offering both immediate and long-term advantages: • Improved Land Use Efficiency: By targeting marginal or low-yield agricultural lands that require excessive inputs, Denmark reduces resource waste and prioritizes areas with higher ecological value. Farmers may adopt innovative technologies like precision agriculture to maximise yields on remaining farmland. • Economic Diversification for Farmers: Financial compensation helps farmers transition into alternative ventures such as eco-tourism, sustainable timber production, or specialty crop farming. This provides more stable and diverse income streams. • Reducing Soil Degradation: Farmland reduction helps restore soil health and fertility, ensuring long-term agricultural productivity while reducing costs associated with soil erosion and nutrient loss. • Climate Change Mitigation: Reforested areas will sequester carbon, contributing to global climate goals and reducing future economic risks tied to climate impacts. • Balancing Global Food Security: By improving agricultural efficiency and focusing on high-value crops, Denmark can contribute to sustainable global food systems without overproducing low-margin commodities.

CSRD Nature Metrics Compared with TNFD, CDP, and GRI 🌎 Nature is becoming a central pillar of sustainability reporting, reflecting its critical role in global environmental and economic systems. Companies are increasingly expected to disclose their impacts and dependencies on nature with greater precision and alignment to evolving standards. A recent comparative analysis highlights how CSRD’s nature-related metrics overlap with TNFD, CDP, and GRI standards, showcasing a growing convergence across frameworks. Pollution, water, biodiversity, and waste emerge as key thematic areas where disclosure expectations are sharpening. Pollution metrics, including emissions, microplastics, and expenditures related to incidents, demonstrate strong alignment across frameworks, signaling a heightened need for transparent reporting on pollution-related risks and costs. Water-related disclosures, such as consumption, withdrawals, and discharges, show close alignment, especially in stress-prone areas. This reinforces the critical role of water stewardship as a material topic across industries. Biodiversity metrics reveal a more fragmented alignment, yet the direction of travel is clear: the use of land, protection of nature-oriented areas, and ecosystem impact assessments are gaining prominence in corporate reporting expectations. Waste management metrics, particularly on secondary material use, total waste generated, and breakdowns by type and treatment, are highly aligned. Circular economy principles are becoming embedded in nature-related disclosures. Financial information about the risks and opportunities linked to environmental impacts is increasingly demanded across all categories. Forward-looking disclosures are no longer optional—they are becoming a regulatory and market expectation. Nature reporting is evolving rapidly. Businesses that proactively integrate nature-related metrics into sustainability strategies will be better positioned to navigate regulatory shifts, meet stakeholder expectations, and build long-term resilience. #sustainability #sustainable #business #esg #nature #biodiversity

Why is sustainable transport essential for greener cities and a better world? Global #transportation accounts for 25% of CO2 emissions worldwide. 91% of the energy used in motorised land, sea and air transport remains derived from #fossilfuels. Without major diversification towards clean and low-carbon transport, this figure is set to increase by nearly 60% by 2050. This is a particularly urgent issue in urban zones of the world. Our cities occupy just 3% of the Earth’s land, but drive between 60-80% of energy consumption and are responsible for a staggering 75% of global CO2 emissions. Cities are also the engines of the world’s economy and transport is vital to promote connectivity, trade and employment in our urban hubs. Therefore, we’re going to need to overhaul the way transport works and how our cities are built. We need transformation to make #sustainablemobility a reality.  The good news is that we do have solutions that exist, like #EVs and renewable aviation fuel. But we need to further accelerate change through a global concerted effort to support clean energy-powered mass transit systems, from electrifying our marine networks to railways. We also need to make our urban environments geared towards carbon-free travel with biking and walking lanes.  All of these actions will require not only new innovations, nature-positive city planning and financing, but indeed #collaboration across industries and borders to fully steer our societies towards a sustainable path.  As individuals, we can also take a stand by embracing car-free modes of transport and prioritise the planet in our daily travel decisions. Whether that means carpooling and opting for public transport to minimise traffic congestion, or choosing to join the #flygskam movement to go flight-free as much as possible. Every little bit counts.  As the United Nations has stated before: Sustainable transport is not an end in itself, but a means to achieve sustainable development. By making environmentally-friendly transportation widespread, accessible and affordable to all in cities and beyond, we move closer to reaching multiple goals—climate resilience, disaster mitigation, global net-zero, healthy breathable air, and inclusive human settlements. These interrelated targets are all laid out under #SDG9 and #SDG11.  #WorldSustainableTransportDay is celebrated annually to highlight the importance of green mobility, reminding us that we will only achieve our #GlobalGoals with clean transport systems. As UN Secretary-General António Guterres has emphasised, we have ‘no time to waste — let’s get moving’. With sustainable transport, we can pave the route towards a greener, healthier and more equitable world. #SDGs #SustainableTransport #WSTD

#Climate reporting is dead. Long live 氣候揭露! [with a #DoubleMateriality cherry on top] ICYMI, late last year, the Chinese Ministry of Finance released 企業永續揭露準則第1號－氣候 (试行) | Corporate Sustainable Disclosure Standard No. 1 – Climate (Trial). The Chinese standard aligns with IFRS’s S2 climate reporting standard, but importantly includes the requirement to report on both how climate change affects a company’s finances as well as the impact of their business activities and value chains on the environment. Also notable that whilst the Ministry has said the new standard will at first be voluntary, in time it will expand implementation “from listed companies to non-listed companies, from large enterprises to SMEs, from qualitative requirements to quantitative requirements, and from voluntary disclosure to mandatory disclosure.” This new reporting standard is particularly relevant for Aotearoa #NewZealand given China’s position as one of the country’s most important trading partners, and the rapidly shifting geopolitical sands. The standard’s release also reinforces calls for NZ companies impacted by the recent rollback of domestic #ClimateReporting requirements to continue building on the foundations of recent years, understand and focus on where the process can best derive strategic value, and prepare for the inevitable requests from international value chains and customers captured by their reporting regimes.

Beaver rewilding is gathering momentum across the U.S., driven by a newfound appreciation of the ecological benefits of these ecosystem engineers, highlighted by tools built by NASA. Healthy beaver populations have been shown to enhance biodiversity, promote drought resilience, and maintain water availability on the land longer, serving as an immense boon to ecosystems. A novel project in Idaho is taking this work further. Leveraging remote sensing data from NASA, it's providing a new way to assess which streams are most suitable for beaver reintroduction, and to monitor the subsequent ecological transformation. This initiative represents a collaborative effort between researchers, ranchers, conservationists, and local organisations, all driven by a shared commitment to ecological restoration. The free access to NASA's remote sensing data addresses two major challenges in the field: quantifying change over time and consistently monitoring vast areas. Traditional field measurements are time-consuming and limit our capacity to track changes across seasons and regions. By contrast, the regular, comprehensive data provided by NASA's Earth-observing missions offer a scalable solution. The early results are confirming that by creating natural dams, beavers hold water on the land longer, fostering the growth of vegetation, providing fresh drinking water, enhancing grazing land for cattle, and fortifying landscapes against fire and drought. On a micro level, the impact is clear. Beaver rewilding efforts since 2014 along Birch Creek, near Preston, Idaho, have led to the creation of over 200 beaver dams. This has increased the stream's flow duration by 40 days annually! A similar project in Oregon saw a 170% increase in steelhead trout, illustrating the positive ripple effects of beaver reintroduction on local fauna. NASA are developing a suite of digital tools, including the Beaver Restoration Assessment Tool (BRAT), two applications using Earth observations to measure rewilding impacts, and a smartphone app for comparing field site photos over time. #rewilding #generationrestoration #climateadaptation #nasa https://lnkd.in/e2EtVS-6

It is time for #NVIDIA, #AMD, #Intel and every other AI hardware vendor to stop hiding the true environmental cost of their products. Billions are being invested in AI hardware, yet we still lack transparent data on embodied emissions, resource use, water intensity and toxicity impacts. NVIDIA (et al) release selective impact assessments designed to meet compliance needs but conveniently exclude everything that matters. A great new study helps to fill some key gaps: “More than Carbon: Cradle-to-Grave Environmental Impacts of GenAI Training on the NVIDIA A100 GPU”. Its got so much valuable info and is worth a read. https://lnkd.in/eSwzd624 Unlike most studies that rely on secondary data, the researchers physically dismantled an NVIDIA A100 GPU ground it up and carried out a full elemental composition analysis. Using that data, they modelled sixteen environmental impact categories across the entire life cycle, covering raw material extraction, manufacturing, model training and end-of-life. The findings are so interesting: 1. Manufacturing is the dominant source of impact a) Manufacturing a accounts for 81.8% of the total climate impact and 80% of fossil resource depletion before it trains a single model. b) 71% of mineral and metal depletion and 94.5% of cancer-related human toxicity impacts occur during manufacturing. c) The copper-heavy heatsink alone is responsible for 91% of cancer related toxicity, 86% of freshwater eutrophication and 91% of land use impacts. d) Semiconductor fabrication at 7nm is a hotspot, with each square cm of silicon requiring significantly more energy, chemicals and water than previous generations. 2. Training is highly energy intensive but not the whole story a) Training GPT-4 on A100s consumed the equivalent of 11,522 people’s annual climate-change budget. b) In Iowa, where GPT-4 was trained, the carbon-intensive grid drives 96.8% of the training climate footprint. c) Focusing on energy efficiency alone will not solve the problem. Operational carbon dominates the impact, but toxicity, water stress and mineral depletion are driven by manufacturing. 3. AI’s material dependency is huge and invisible a) An A100 contains dozens of rare earths & critical minerals including copper, gold, palladium, platinum and tantalum. b) They found a 33% increase in mineral and metal depletion impacts compared with standard LCAs (i.e. secondary data significantly underestimates things). c) Semiconductor fabrication is concentrated in water-stressed regions such as Taiwan, South Korea and Arizona, yet vendors do not disclose water intensity per GPU. This is why hardware vendors must conduct full component level PCF's incl. verifiable embodied impact data. Without transparency we are literally flying blind whilst they make trillions of dollars. This study is an important milestone, but it also shows how little we really know about the environmental impact of AI hardware. Vendors... stop hiding
