Do you are feeling a bit misplaced when folks confer with sure environmental sustainability subjects and aren’t positive the place to start out in the case of studying extra? Sustainability 101 is a weblog sequence that you could flip to for details about completely different environmental phrases that will come up at work, throughout discussions with associates, and even at your annual vacation gathering.
Each product has a narrative. From the uncooked supplies used to create it, to the power it consumes, to the place it finally ends up when it’s now not helpful— every stage impacts the surroundings. Life Cycle Assessments, or LCAs, assist us estimate that impression and determine areas for enchancment all through a product’s life cycle.
LCAs assist companies perceive the environmental footprint of their merchandise, processes, or providers throughout each stage of their life cycle. From power use to water consumption, LCAs reveal important information that may drive extra sustainable selections.
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 — corresponding to changing supplies into completed merchandise.
- Transportation and distribution — together with the journey to shops, warehouses, and prospects.
- Utilization — corresponding to sources consumed when a product is in use.
- Finish-of-life — what occurs to a product after use: as an example, recycling, reuse, or landfill disposal.
LCAs estimate the environmental impression 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 scale back their environmental impression.
* Be aware, the examples listed above should not exhaustive and are supposed to be illustrative.
What do LCAs estimate?
LCAs transcend simply evaluating a product’s carbon footprint to incorporate subjects corresponding to water consumption, power 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 could 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 contemporary water is consumed throughout manufacturing and product use. For instance, producing sufficient cotton for a single T-shirt can require 1000’s of liters of water, with further water used for dyeing, washing, and cleansing the shirt over its lifetime.
Major Power Demand (Power consumption): LCAs consider the power sources 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 probably pollute water sources, and the shirt itself might finally find yourself in a landfill.
Abiotic Depletion Potential (Useful resource depletion): LCAs estimate using finite sources 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 is usually a highly effective instrument for driving innovation and lowering environmental impression.
They’ll supply tangible advantages for companies aiming to fulfill their sustainability objectives. By figuring out probably the most resource-intensive phases of a product’s life, corporations can goal environmental “hotspots” and implement modifications corresponding to utilizing renewable power to energy manufacturing websites or switching to extra sustainable supplies that cut back their total impression. These insights can drive innovation, enabling the design of merchandise which are extra energy-efficient, sturdy, and round with diminished resource-intensiveness and environmental impression.
For instance, it’s estimated that over 80% of product-related environmental impacts are decided throughout the design part.1 LCAs might help examine options and perceive trade-offs when choosing elements, course of steps or disposal sorts. By integrating LCAs early within the design course of, corporations can enhance sustainability outcomes.
Publishing LCA outcomes helps to reinforce company transparency and help environmental reporting. Sharing these studies builds belief with prospects, staff, traders, and different stakeholders, whereas guaranteeing compliance with international sustainability requirements and reporting frameworks.
How are LCAs performed?
Conducting an LCA is a structured course of that includes gathering information throughout each part of the product lifecycle, assessing environmental impacts, and deciphering the outcomes to help 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 based mostly on ISO’s framework.
Cisco’s method to Life Cycle Assessments
At Cisco, LCAs play a key function in our efforts to estimate and reduce the environmental impression of our merchandise.
Lately, we introduced that Cisco has made these assessments publicly obtainable, sharing LCAs for a variety of our merchandise on the Sustainability Assets part of our web site. Cisco has already accomplished 23 LCAs throughout 8 enterprise items prior to now two years and plans to publish further assessments throughout key product strains in 2025. Sharing these outcomes helps transparency and demonstrates our dedication to measurable progress.
Whereas many know-how corporations publish LCAs, Cisco is among the first to provide them for networking tools, corresponding 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 grow to be obtainable.
LCAs are a part of how we method sustainability holistically. LCA information helps our round design technique— to develop merchandise and sources which are reused, repurposed, and stored in circulation for so long as doable. By evaluating the whole lot from materials sourcing to end-of-life disposal, we acquire important insights that information our product design and innovation.
