Do you are feeling a bit misplaced when folks consult with sure environmental sustainability matters and aren’t certain the place to begin on the subject of studying extra? Sustainability 101 is a weblog sequence you could flip to for details about totally different environmental phrases that will come up at work, throughout discussions with pals, and even at your annual vacation gathering.
Each product has a narrative. From the uncooked supplies used to create it, to the vitality it consumes, to the place it finally ends up when it’s not helpful— every stage impacts the setting. Life Cycle Assessments, or LCAs, assist us estimate that affect and determine areas for enchancment all through a product’s life cycle.
LCAs assist companies perceive the environmental footprint of their merchandise, processes, or companies throughout each stage of their life cycle. From vitality use to water consumption, LCAs reveal vital information that may drive extra sustainable choices.
What’s a Life Cycle Evaluation (LCA)?
A Life Cycle Evaluation evaluates the complete life cycle of a product, together with*:
- Uncooked materials extraction. One instance is sourcing minerals, metals, or pure fibers.
- Supplies and product manufacturing — similar to changing supplies into completed merchandise.
- Transportation and distribution — together with the journey to shops, warehouses, and prospects.
- Utilization — similar to assets consumed when a product is in use.
- Finish-of-life — what occurs to a product after use: for example, recycling, reuse, or landfill disposal.
LCAs estimate the environmental affect at every stage, offering an image of a product’s footprint. Companies depend on LCAs to determine the place the best impacts happen and discover alternatives to cut back their environmental affect.
* Notice, the examples listed above will not be exhaustive and are supposed to be illustrative.
What do LCAs estimate?
LCAs transcend simply evaluating a product’s carbon footprint to incorporate matters similar to water consumption, vitality demand, useful resource depletion, waste era, and air pollution. Let’s take the instance of a seemingly easy T-shirt to discover an instance of what will be measured:
World Warming Potential (GWP): LCAs estimate the greenhouse gases like carbon dioxide (CO₂) and methane (CH₄) that contribute to local weather change. For a T-shirt, these emissions happen at each stage—from producing cotton to powering factories and transporting the completed product.
Blue Water Consumption (Water utilization): LCAs estimate how a lot recent water is consumed throughout manufacturing and product use. For instance, producing sufficient cotton for a single T-shirt can require hundreds of liters of water, with extra water used for dyeing, washing, and cleansing the shirt over its lifetime.
Main Vitality Demand (Vitality consumption): LCAs consider the vitality assets used to provide, distribute, and energy a product. For a T-shirt, this contains operating textile equipment in factories and transporting the shirt across the globe.
Ecotoxicity (Waste and air pollution): LCAs estimate pollution that have an effect on air, water, and land. In T-shirt manufacturing, chemical dyes and by merchandise can doubtlessly pollute water sources, and the shirt itself may finally find yourself in a landfill.
Abiotic Depletion Potential (Useful resource depletion): LCAs estimate the usage of finite assets like metals, minerals, and fossil fuels. In our T-shirt instance, rising cotton depletes soil vitamins, whereas producing artificial fibers like polyester depends on fossil fuels.
By capturing this full vary of environmental impacts, LCAs empower companies to prioritize extra sustainable actions throughout their operations and product design.
Why LCAs matter for companies
LCAs generally is a highly effective instrument for driving innovation and lowering environmental affect.
They’ll provide tangible advantages for companies aiming to fulfill their sustainability objectives. By figuring out essentially the most resource-intensive phases of a product’s life, firms can goal environmental “hotspots” and implement adjustments similar to utilizing renewable vitality to energy manufacturing websites or switching to extra sustainable supplies that scale back their general affect. These insights can drive innovation, enabling the design of merchandise which are extra energy-efficient, sturdy, and round with decreased resource-intensiveness and environmental affect.
For instance, it’s estimated that over 80% of product-related environmental impacts are decided throughout the design part.1 LCAs will help evaluate alternate options and perceive trade-offs when deciding on parts, course of steps or disposal sorts. By integrating LCAs early within the design course of, firms can enhance sustainability outcomes.
Publishing LCA outcomes helps to boost company transparency and assist environmental reporting. Sharing these studies builds belief with prospects, staff, traders, and different stakeholders, whereas guaranteeing compliance with world sustainability requirements and reporting frameworks.
How are LCAs carried out?
Conducting an LCA is a structured course of that entails gathering information throughout each part of the product lifecycle, assessing environmental impacts, and deciphering the outcomes to assist initiatives like net-zero objectives and round product design.
LCAs observe globally accepted requirements, such because the Worldwide Group for Standardization’s (ISO) 14040 and 14044. There are different requirements which are additionally primarily based on ISO’s framework.
Cisco’s strategy to Life Cycle Assessments
At Cisco, LCAs play a key function in our efforts to estimate and decrease the environmental affect of our merchandise.
Lately, we introduced that Cisco has made these assessments publicly obtainable, sharing LCAs for quite a few our merchandise on the Sustainability Sources part of our web site. Cisco has already accomplished 23 LCAs throughout 8 enterprise items up to now two years and plans to publish extra assessments throughout key product strains in 2025. Sharing these outcomes helps transparency and demonstrates our dedication to measurable progress.
Whereas many know-how firms publish LCAs, Cisco is among the first to provide them for networking tools, similar to Catalyst switches. Cisco’s Chief Sustainability Workplace and Provide Chain Sustainability groups proceed to accomplice with our colleagues throughout the corporate to provide these studies, and we plan to proceed publishing them as they develop into obtainable.
LCAs are a part of how we strategy sustainability holistically. LCA information helps our round design technique— to develop merchandise and assets which are reused, repurposed, and stored in circulation for so long as potential. By evaluating all the pieces from materials sourcing to end-of-life disposal, we acquire vital insights that information our product design and innovation.
