LCA and carbon footprint assessment from experts

Most life cycle assessments of batteries assume a single, static impact value for each component material. That hides the reality that the same battery, built to the same chemistry, can carry a very different carbon footprint depending on where and how its raw materials are produced. In this foundational study, Minviro modelled an NMC-811 battery, the most common chemistry in Western EVs, across low, baseline and high-impact supply chain scenarios to show just how much that variability matters at the level of a finished battery pack.

Steel underpins almost every sector, but making it is responsible for 7 to 9% of global greenhouse gas emissions. In Indonesia, where the industry has grown around 21% a year since 2013, roughly 80% of production still uses the blast furnace–basic oxygen furnace (BF-BOF) route, one of the most carbon-intensive ways to make steel. With the EU’s Carbon Border Adjustment Mechanism and offtakers such as data centres and automakers demanding lower-carbon steel, Minviro carried out a life cycle assessment of Indonesian hot-rolled coil to quantify its footprint, find the hotspots, and set out the decarbonisation options.

Indonesia produces more than 60% of the world’s nickel, making it indispensable to EV battery supply as cathodes shift toward nickel-rich chemistries. But the route that built that dominance, pyrometallurgical processing of saprolite ore into nickel pig iron and matte, is among the most carbon-intensive in the global mining sector. Minviro’s life cycle assessment quantifies that footprint, models how fast Indonesia’s reserves are depleting, and shows how far emissions could be cut. The conclusion is stark: without decarbonisation, high-carbon Indonesian nickel risks undermining the very EVs it supplies and losing access to key markets.

EV batteries are projected to account for around 60% of global nickel demand by 2040, and Southeast Asia, led by Indonesia and the Philippines, holds some of the world’s largest laterite reserves. That makes the region central to both EV growth and transport decarbonisation. Working with the Economic Research Institute for ASEAN and East Asia (ERIA), Minviro combined supply-demand modelling, reserve depletion assessment and life cycle assessment with life cycle costing to test whether ASEAN can meet EV nickel demand, how long its reserves will last, and how cleanly battery-grade nickel can be produced.

As demand for battery metals climbs, with lithium and nickel demand projected to grow 40 times between 2020 and 2040, recycling is increasingly seen as the lower-carbon, more secure route to supply. The EU Battery Regulation will require the carbon footprint of both recycling and recycled content to be reported. To test the common assumption that recycled beats virgin, Minviro built a granular, engineering-based recycling model and compared recycled nickel sulfate and lithium carbonate from spent NMC batteries against the main primary production routes.

Solar PV is one of the clearest wins in decarbonisation, producing on average 20 times fewer emissions than coal power and generating 20 to 30 times more energy over its life than goes into making it. But manufacturing solar modules is energy- and material-intensive, and that embodied footprint is coming under regulatory scrutiny. Minviro assessed the product carbon footprint of a monocrystalline silicon module, from silica extraction to finished panel, to show which stages matter most and how much supply chain choices change the result.

Heat pumps are established as a low-carbon alternative to gas boilers, with Gemserv’s research finding a gas boiler generates 55% more emissions in use than a 10kW air source heat pump. But the emissions embodied in making a heat pump are increasingly under scrutiny from regulators, investors and customers. Minviro and Gemserv ran a cradle-to-gate life cycle assessment of a 10kW air source heat pump to measure those embodied emissions, identify the hotspots, and show how far they can be reduced.

Demand for battery raw materials such as lithium, nickel and cobalt is projected to rise 15 to 20 times between 2020 and 2050, raising hard questions about supply security and end-of-life waste. A circular economy, through reuse, remanufacturing and recycling, is widely seen as part of the answer. To test how much it can deliver and when, Minviro combined System Dynamics modelling with prospective life cycle assessment, using the UK as a case study to map material recovery and battery carbon footprints from 2020 to 2050.

Graphite is in around 96% of lithium-ion battery anodes, with each battery needing 10 to 15 times more graphite than lithium. Despite that, its environmental footprint is often overlooked and, more importantly, underestimated. Producing anode-grade graphite is highly energy-intensive, and much of the world’s supply is made in coal-dominated grids such as Inner Mongolia, where low-cost power carries a high carbon cost. Minviro modelled natural and synthetic graphite production using higher-quality, more recent data and found the true climate impact can be up to ten times higher than published values.

Battery demand is set to climb from around 1 TWh in 2023 to nearly 7 TWh by 2030, and with it comes scrutiny of the environmental footprint of every stage in the value chain. The EU Battery Regulation, in force since August 2023, makes carbon footprint declarations, due diligence and the battery passport mandatory in phased stages, starting with EVs. In this joint paper, Minviro and Worley argue that meeting these requirements is not just about measuring impact after the fact. The real opportunity is to design lower-impact batteries from project inception, and to be able to prove it.

Sodium-ion batteries (SIBs) are attracting attention as a possible answer to lithium scarcity and price volatility. Sodium makes up 23,600 ppm of the earth’s crust against just 20 ppm for lithium, and sodium hydroxide costs a fraction of lithium hydroxide. But abundance and low cost do not automatically translate into a lower environmental footprint. Minviro assessed five sodium-ion chemistries against lithium-ion NMC and LFP using life cycle assessment, looking beyond climate change to resource use and acidification, to test whether the “sustainable by default” assumption holds.

Lithium-iron-phosphate (LFP) has moved from a China-centred cathode chemistry to a serious global competitor to nickel-based cells, helped by its cycle life, safety and lower cost. As the EU Battery Regulation brings carbon footprint requirements into force, manufacturers now have to weigh environmental impact alongside cost to stay commercially viable. Minviro and Exawatt combined life cycle assessment and bottom-up cost modelling across 27 LFP production pathways to show where the real decarbonisation opportunities lie, and what they cost.

Nickel is a cornerstone of the battery supply chain, and demand is rising as cathode chemistries shift toward higher nickel content. But “nickel” is not a single product with a single carbon number. The same battery-grade material, nickel sulfate hexahydrate, can be produced through several routes, each with its own resources, energy sources and chemistry. Minviro’s white paper measures this variability and explains why knowing the source and production route is essential to understanding a supply chain’s true climate change impact.

Most LCA programmes stall at the same point: the supplier data request. Teams either ask for too much and get nothing back, or collect data with no governance and can’t defend it under review.

Minviro’s LCA platform, XYCLE, has been featured in the Verdantix Smart Innovators: LCA Software (2025) report, published in November 2025. The report is an independent assessment by analyst firm Verdantix of the life cycle assessment software market, examining how vendors help organisations automate and scale LCAs in response to growing regulatory and commercial demand. XYCLE was one of the providers selected for evaluation, and the report highlights Minviro’s work on AI-assisted modelling and supply chain data integration as examples of innovation in the sector.

Without traceability infrastructure, low-carbon hydrogen is indistinguishable from high-carbon hydrogen the moment it enters a shared supply chain. Over two years and £5 million of UK–Australia funding, the HyPACT consortium has built a working system that links a live electrolyser to a verified Digital Product Passport — automatically, at batch level. Workshop 2 is where the people who produce, buy, certify and regulate hydrogen help shape what the standard becomes.

Hydrogen fuel cells convert hydrogen into electricity, producing only water and heat at the point of use, which makes them a promising technology for decarbonising transport, industry and stationary power. But hydrogen is an energy carrier, not a source, so a fuel cell's true environmental performance depends overwhelmingly on how its hydrogen is produced, alongside the impacts of the specialised materials in the cell itself. This guide, part of Minviro's "Path to Product" series, examines both proton exchange membrane fuel cells (PEMFCs) and solid oxide fuel cells (SOFCs), walking through their materials, manufacturing hotspots, the decisive role of hydrogen sourcing, and the tightening regulatory landscape, all through the lens of life cycle assessment.

Neodymium-iron-boron (NdFeB) permanent magnets are crucial to the energy transition, powering high-performance motors, direct-drive wind turbines, robotics and a wide range of clean energy technologies. But their efficiency comes with a complex web of critical materials, carbon-intensive manufacturing, and a near-total reliance on rare earth elements sourced overwhelmingly from China. With demand accelerating and recycling rates extremely low, the supply chain faces real sustainability and resilience challenges. This guide, part of Minviro's "Path to Product" series, walks through the materials behind permanent magnets, how they are made, the levers for cutting impact, the circular opportunities, and what emerging regulation like the EU Critical Raw Materials Act will require, all through the lens of life cycle assessment.

Semiconductors are foundational to almost every modern technology, from smartphones and data centres to electric vehicles and renewable energy systems, and the global industry is valued at around $500 billion a year. But making chips is highly energy- and resource-intensive, relying on ultra-pure silicon and a range of critical materials sourced from concentrated, often geopolitically sensitive supply chains. As demand surges, manufacturers face mounting regulatory, environmental and commercial pressure to prove their sustainability. This guide, part of Minviro's "Path to Product" series, walks through the materials behind chips, how they are made, the levers for cutting impact, the circular opportunities, and what emerging regulation like the EU's ESPR will require, all through the lens of life cycle assessment.

As demand for batteries grows across electric vehicles, energy storage and consumer electronics, building responsible supply chains has become both complex and critical. Manufacturers face overlapping pressures: the carbon intensity of production, the ethical and environmental challenges of sourcing lithium, cobalt and nickel, and tightening regulation led by the EU Battery Regulation. This guide, part of Minviro's "Path to Product" series, brings these threads together, walking through the key battery materials and their impacts, how cells are manufactured, the most effective levers for cutting carbon, the circular economy options, and what regulatory compliance now requires, all through the lens of life cycle assessment.

Steel is one of the most essential materials of modern society, produced at over 1.8 billion tonnes a year and providing structure, directly or indirectly, to virtually every industry, from construction and transport to wind turbines and machinery. That scale comes at a cost: the steel industry contributes around 8% of total global emissions, making its decarbonisation one of the most important challenges in heavy industry. Steel is an alloy of iron and carbon, tailored to different uses by adding elements like chromium, nickel and manganese. This guide, a special edition of Minviro's "Explore the Elements" series, introduces steel's raw materials, production routes, emerging green technologies and the role of LCA.

Titanium is a strong, lightweight, silvery-grey metal known for its exceptional strength-to-weight ratio and corrosion resistance. The ninth most abundant element in the Earth's crust, it occurs mainly in the minerals ilmenite and rutile, and its properties make it essential across aerospace, defence, medical devices and consumer products. But turning titanium ore into usable metal relies on the Kroll process, a decades-old route that is highly energy-intensive and emits direct CO₂. This guide, part of Minviro's "Explore the Elements" series, introduces titanium's geology, production routes, applications and the role of LCA.

Gold is a dense, yellow metal that is conductive, non-corrosive and highly malleable, valued throughout history for its chemical stability and appeal. Its uses span finance, jewellery, electronics, medicine and dentistry, and increasingly new-generation photovoltaics. Gold is scarce in the Earth's crust and accumulates in placer and lode deposits, with South Africa, Australia, the US and Russia among the major producers, and like platinum group metals it is often mined alongside copper and silver. That scarcity means a large processing effort per kilogram, and a correspondingly high environmental footprint. This guide, part of Minviro's "Explore the Elements" series, introduces gold's deposits, extraction routes, market structure and the role of LCA.

Nickel is a hard, silvery-white transition metal whose corrosion resistance, high-temperature strength and electrochemical properties make it essential to stainless steel, alloys, catalysts and, increasingly, batteries. It has become a critical material in the energy transition, as battery makers raise the nickel content of NMC cathodes to boost energy density. But nickel comes from two very different ore types, sulphides and laterites, whose processing routes diverge sharply in complexity, co-products and carbon footprint. This guide, part of Minviro's "Explore the Elements" series, introduces nickel's sources, processing routes and the role of LCA.

Platinum is almost never discussed alone. It comes as a sextet with palladium, rhodium, iridium, osmium and ruthenium, collectively the platinum group metals (PGM), whose geology, processing and applications are so intertwined that they are treated as a single family. They are by far the rarest metals in the Earth's crust, present at parts-per-billion levels, and that scarcity, combined with extraordinarily complex processing, makes their per-kilogram environmental impact orders of magnitude higher than common metals. As demand shifts from catalytic converters toward hydrogen fuel cells, this guide, part of Minviro's "Explore the Elements" series, introduces PGM geology, processing routes, markets and the role of LCA.

Cobalt is a greyish-silver ferromagnetic metal that is scarce in the Earth's crust, present at just 15–35 parts per million. Despite that scarcity it has become a key battery material, valued for the stability and safety it brings to lithium-ion cathodes at high temperatures. In 2023, global cobalt supply passed 200,000 tonnes for the first time, with the EV industry now driving close to half of all demand. But cobalt is almost always produced as a byproduct of copper or nickel mining, and where it comes from strongly shapes how it is processed and what it costs the environment. This guide, part of Minviro's "Explore the Elements" series, introduces cobalt's sources, processing routes and the role of LCA.

Graphite is a pure form of carbon with a layered hexagonal structure that conducts heat and electricity efficiently, and it has become indispensable to the clean energy transition as the primary anode material in lithium-ion batteries. It comes in several natural grades and a man-made synthetic form, and the two diverge sharply in how they are produced and what they cost the environment. With over half of projected graphite demand to 2026 coming from EV batteries and steel, understanding its footprint has become essential. This guide, part of Minviro's "Explore the Elements" series, introduces graphite's forms, applications, the natural versus synthetic divide, and the role of LCA.

Aluminium is a soft, silvery-white metal renowned for its strength-to-weight ratio: three times lighter than copper, yet stronger than steel when alloyed. As the third most abundant element in the Earth's crust, it is found almost entirely in bauxite ore, and turning that ore into metal takes substantial electricity, which is the source of its large carbon footprint. At the same time, aluminium is highly recyclable, and remarkably, nearly 75% of all the aluminium ever produced is still in use today. This guide, part of Minviro's "Explore the Elements" series, introduces aluminium's geology, production routes, market and the sustainability challenges and opportunities that define it.

Silicon is the most abundant material in the Earth's crust, making up around 28% of its mass, yet because of its high affinity for oxygen it is almost never found pure in nature, occurring instead as sand, quartz and silicates. A metalloid with semiconductor properties, it underpins both the digital age and the clean energy transition: it is the basis of chips and circuits and accounts for the overwhelming majority of solar photovoltaic material. But silicon's production routes are energy and CO₂ intensive, which makes understanding and measuring their impact essential. This guide, part of Minviro's "Explore the Elements" series, introduces silicon's properties, processing routes, market and carbon footprint.

Lithium is the lightest metal and the lightest solid element, a soft, silvery-white alkali metal whose high electrochemical potential and thermal resistance make it indispensable to modern batteries. Found in continental brines, pegmatite rocks and certain minerals, it is central to electric vehicles, portable electronics and renewable energy storage. But the way lithium is produced varies enormously depending on the deposit, and so do its environmental impacts. This guide, part of Minviro's "Explore the Elements" series, introduces lithium's geology, the distinct production routes, supply dynamics and the sustainability challenges shaping the industry.

Copper is one of the most versatile and widely used metals, prized for its exceptional electrical and thermal conductivity. It is the material of choice for electrical wiring, motors and generators, and is increasingly central to renewable energy systems like solar panels and wind turbines. Abundant in the Earth's crust across minerals such as chalcopyrite, bornite and malachite, it is a cornerstone resource for modern civilisation, but its extraction and processing are energy-intensive and carry real environmental impacts. This guide, part of Minviro's "Explore the Elements" series, introduces copper's geology, production routes, market dynamics and the sustainability challenges shaping the industry.

Rare earth elements are the unsung enablers of modern technology, found in the high-strength magnets that drive electric vehicle motors and wind turbine generators. Despite the name, they are relatively abundant in the Earth's crust; the challenge is that their concentrations are low, making them hard to mine economically, and their production is chemically intensive and geographically concentrated. This guide, the first in Minviro's "Explore the Elements" series, introduces what REEs are, how they are produced, why they are considered critical materials, and why life cycle assessment is essential to understanding their environmental footprint.

Decarbonisation has shifted from an environmental priority to a business-critical strategy, shaped by regulation, investor pressure and changing markets. Yet many organisations struggle to reconcile environmental goals with financial reality, risking unforeseen costs and missed opportunities. This guide shows how integrating Life Cycle Assessment (LCA), Life Cycle Costing (LCC) and Environmental Techno-Economic Assessment (eTEA) lets organisations evaluate environmental and economic trade-offs together, turning sustainability from a cost centre into a source of competitive advantage.

The EU Battery Regulation, in force since February 2024, is a major step toward regulating the environmental impact of battery production and supply chains, and it designates life cycle assessment as the primary method for calculating a battery's carbon footprint. For anyone producing, importing or distributing batteries, this brings new obligations: mandatory carbon footprint declarations, calculated via LCA and recorded in a digital battery passport. This guide explains how the LCA methodology works under the regulation, what data is required, and how to prepare, while noting that the Delegated Act governing the detail is still evolving.

Consumer demand for low-impact products has created a strong commercial case for promoting environmental performance, but misleading green claims are everywhere. A 2020 European Commission study found that 53% of green claims were vague, misleading or unfounded, and 40% were unsubstantiated. As the EU's Green Claims Directive and similar national rules come into force, every company will need more rigour in how it makes and markets environmental claims. This guide explains how life cycle assessment underpins credible claims, and sets out Minviro's four guiding principles for substantiating and communicating them without greenwashing.

Supplier primary data is what makes a product footprint decision-grade and defensible under customer, regulatory and internal scrutiny. But scaling LCA across suppliers, regions and large portfolios brings real operational complexity: inconsistent submissions, unclear ownership, fragmented tracking, and outputs that are hard to validate. Without a clear process, data collection becomes reactive and unsustainable across reporting cycles. This guide sets out a practical workflow, with templates, governance principles and quality checks, for requesting, receiving, validating, governing and reusing supplier data, whether you are running a small pilot or operationalising LCA across a global portfolio.

Life cycle assessment used to be an analytical exercise: commission a study, get a result, answer a question. Now organisations embed LCA into procurement, product design, compliance and reporting, which means it has to function as infrastructure: reproducible, explainable and able to withstand scrutiny. When that happens, outcomes depend less on the impact method and more on whether the underlying data reflects how products are actually made and sourced. This paper sets out why a deliberate primary data strategy, focused where it changes decisions, is what separates defensible results from a false sense of rigour.
