Environmental Engineering Impact Studies

The frog that halted a dam In Brazil, conservation victories are often framed as heroic struggles against deforestation or mining. In 2014, one involved a toad, reports Thamys Trindade. Melanophryniscus admirabilis, a thumb-sized amphibian found only along a short stretch of the Forqueta River in Rio Grande do Sul, became the decisive factor in stopping a small hydroelectric dam planned less than 300 meters from its habitat. Classified as critically endangered after careful fieldwork, the species forced regulators and prosecutors to accept an inconvenient conclusion: even modest infrastructure can be incompatible with biological survival. That episode is now more than a legal curiosity. In 2024, record floods swept through southern Brazil, submerging the rocky outcrop where the toad breeds and raising doubts about whether the population still existed. When researchers returned in 2025, they found fewer animals than in peak years, but evidence of continued reproduction. Tadpoles were present. Adults had shifted micro-habitats. The system, though altered, had not collapsed. The story carries a lesson with broader relevance. Environmental impact assessments tend to treat extreme climate events as statistical outliers. Yet the National Water and Basic Sanitation Agency projects that floods in southern Brazil could become up to five times more frequent. For species with narrow ecological requirements, resilience depends not on average conditions, but on whether rare refuges persist through shocks. The admirable little toad survives because its habitat was left intact before disaster struck. Had the dam gone ahead, there would have been no margin for recovery. Conservation, in this sense, functioned less as preservation than as risk management. Small species rarely halt big projects in much of the world. When they do, they sometimes reveal why precaution is cheaper than repair. 🐸 English: https://lnkd.in/gRka7EXG 🐸 Portuguese: https://lnkd.in/g22MBPG9

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!

This is what they don’t want you to know. → Pesticides aren’t the main cause of insect decline. A 33-year study in Western Germany reveals habitat loss, land-use changes, and urbanization are bigger drivers, challenging the oversimplified blame on pesticides. A recent publication called "Insect Decline - Evaluation of Potential Drivers of a Complex Phenomenon." Analysis of the true drivers of insect decline are far more complex and deeply tied to how we manage land and shape our environment. Let's take a deep dive into the publication. The study identifies the intensification of grassland management and shifts in arable land use as likely major contributors to insect decline. Urban areas expanded by about 25%, significantly reducing suitable habitats for insects and, there has been a rebound in insect biomass since 2010. Increasing demand for feed crops (e.g., corn) is closely linked to dairy industry growth, demonstrating how socioeconomic forces influence land use in ways that adversely affect insect habitats. Contrary to some other studies, this research found no compelling correlation between insect decline and either pesticide use or weather/climate factors for this region and timeframe. Notably, the toxic load from pesticides decreased during the period in question, yet insect populations continued to decline. What does this mean? It’s time to shift the conversation. Instead of pointing fingers at crop protection products, we need to look at how farming practices, renewable energy policies, and urban planning are impacting biodiversity. Better land management strategies, preserving habitat diversity, and balancing intensive and extensive farming methods are the real solutions to reversing insect decline. The truth is, tackling this issue isn’t about banning one thing or blaming one industry—it’s about addressing a web of interconnected causes with evidence-based solutions.

What's going to close the $7 trillion gap in climate finance? One of my favorite reports each year from Climate Policy Initiative has some ideas for scaling the investments needed to align with a net-zero pathway. To my mind, this is the best report each year on the state of climate finance. It shows you: -Where financial flows are going from (across public and private sources) -Where money is going to (in industry, location, and activity) -What our estimated needs are across sectors and regions -The mitigation potential to unlock across sectors -Strategies for scaling both public and private investment. Here's a look at the sector gaps we are seeing to date and how they can be overcome. Energy systems- need a 2.5-fold increase in mitigation finance to align with average 2024 to 2030 needs. This sector has the highest emissions reduction potential, requiring investment in renewables, grid modernization, and storage solutions. Transport- also requires an almost 2.5-fold increase in mitigation finance, alongside a significant shift away from high-carbon investments. With a mitigation potential of 3.2 GtCO2e, priorities include electric mobility, public transport expansion, and freight decarbonization. Buildings and infrastructure- mitigation finance must rise nearly 4-fold. This is sector is generally climate-aligned, but further investment can realize its 3.2 GtCO2e mitigation potential. Focus areas include efficiency upgrades, sustainable construction, and low-carbon heating and cooling. Industry- a nearly 24-fold mitigation finance increase, along with reallocation from high-carbon activities, is needed to tap the sector's 4.4 GtCO2e abatement potential. Key areas include clean hydrogen, low-emission manufacturing of cement, steel, and ammonia, and carbon capture, and storage. AFOLU- holds great untapped emissions reduction opportunities—mitigation flows should increase 64-fold from USD 18 billion to USD 1,170 billion annually through 2030 to realize this potential. There is also a need to improve definitional boundaries and enhance tracking of finance flows to this sector.

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.

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

Potential synergies and trade-offs between climate action and the SDGs 🌎 Climate change mitigation measures can have varied impacts on the Sustainable Development Goals (SDGs), as illustrated by the matrix of blue and red bars. Blue bars represent potential synergies where efforts to reduce greenhouse gas emissions simultaneously contribute to SDG targets. Red bars highlight trade-offs that arise when mitigation strategies undermine certain development objectives. The length of each bar indicates the relative strength of the relationship, while the color shade reflects the level of confidence in that assessment. In the energy supply sector, the shift toward low-carbon technologies tends to yield positive outcomes such as improved air quality, economic diversification, and enhanced energy access. However, trade-offs may occur when large-scale infrastructure projects affect local communities, disrupt ecosystems, or require additional land and water resources. Similar complexities appear in energy demand interventions, where efficiency gains and electrification policies can support decent work opportunities but may demand significant up-front investment and workforce reskilling. Land-based mitigation options often provide notable climate and ecosystem benefits, but they also intersect with agriculture, land rights, and biodiversity protection. Excessive reliance on bioenergy crops, for instance, can challenge food security and local livelihoods if planted at scale without proper safeguards. Balanced policymaking is essential to ensure climate efforts do not negatively affect fundamental social and environmental priorities outlined in the SDGs. These considerations are particularly relevant for businesses, as the private sector increasingly aligns growth strategies with sustainability objectives. Assessing and addressing both synergies and trade-offs can inform risk management, long-term planning, and stakeholder engagement. Sound understanding of potential conflicts between climate goals and other development targets supports responsible investment decisions and can strengthen corporate reputation, reduce legal risks, and foster resilience in global value chains. Strategic approaches that integrate multidimensional impact assessments, stakeholder consultations, and cross-sector collaborations can enhance the positive interactions between climate mitigation and SDG outcomes. Such approaches also minimize unintended consequences that could arise from well-intentioned but narrowly focused interventions. By comprehensively evaluating the interconnections among climate measures and the SDGs, decision makers can guide future actions toward balanced, resilient, and inclusive pathways for sustainable development. #sustainability #sustainable #business #esg #climatechange #SDGs

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

Can we use #LCA to measure a product system's impact on #biodiversity ❓ The answer is yes❗ - How reliable are these calculations? Well, that is up for discussion. The impact on biodiversity should always be measured in situ by surveying the species richness of and ecosystem and in combination with other techniques usually including local communities' knowledge. - Why do I think so? Because ecosystems are essentially unique everywhere we look, the impact of a substance emission or material extraction from nature (elementary flows) varies from region to region. It is different to perform a given activity in an urban area than in a rainforest. However, in the last decade, new Life Cycle Impact Assessment methods have been developed to account for regional differences in the impact on biodiversity. They typically focus on assessing the impacts of #landuse and land-use change, as these are among the most significant drivers of biodiversity loss. They may quantify impacts in terms of potentially disappeared fractions of species (PDF) over a certain area and time (usually m2/year) or use other metrics to estimate the change in species richness or ecosystem quality. Some of the methods that include approaches to assess biodiversity impacts are: ➖ ReCiPe: a comprehensive LCIA method that includes a model for assessing land use impacts on biodiversity through the PDF metric. It aims to quantify species loss over a certain area and time due to land use. ➖ IMPACT World+Endpoint: This method includes an attempt to integrate biodiversity impacts through several impact categories such as the PDF from freshwater acidification, damage to ecosystem quality from changes in the soil pH, marine acidification, ecotoxicity, land transformation and occupation, water pollution, and water availability. It is one of the most complete. ➖ USEtox: focused on toxicological impacts, includes considerations for ecotoxicity, which indirectly affects biodiversity by assessing the potential toxic impacts on aquatic and terrestrial species. ➖ Land use biodiversity (Chaudhary et al., 2015): recommended by the UNEP-SETAC Life Cycle Initiative: "The indicator represents regional species loss taking into account the effect of land occupation displacing entirely or reducing the species that would otherwise exist on that land, the relative abundance of those species within the ecoregion, and the overall global threat level for the affected species." I love this method because includes regional factors. ➖ Global Biodiversity Score (GBS): not a traditional LCIA method, GBS is a tool developed to help companies assess their impact on biodiversity. Using a common metric, it translates pressures from organizational activities into impacts on biodiversity. We need to think way beyond #carbonfootprint to aim for a #sustainable world. Biodiversity loss is that issue that although highly interlinked with #climatechange, is the actual major environmental issue we face.
