Do you are feeling a bit misplaced when individuals confer with sure environmental sustainability matters and aren’t certain the place to start out in the case of studying extra? Sustainability 101 is a weblog sequence you can flip to for details about totally different environmental phrases which will come up at work, throughout discussions with mates, 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 now not helpful— every stage impacts the atmosphere. Life Cycle Assessments, or LCAs, assist us estimate that influence and establish 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 vitality use to water consumption, LCAs reveal vital 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 — comparable to changing supplies into completed merchandise.
- Transportation and distribution — together with the journey to shops, warehouses, and clients.
- Utilization — comparable to assets consumed when a product is in use.
- Finish-of-life — what occurs to a product after use: as an illustration, recycling, reuse, or landfill disposal.
LCAs estimate the environmental influence at every stage, offering an image of a product’s footprint. Companies depend on LCAs to establish the place the best impacts happen and discover alternatives to cut back their environmental influence.
* Observe, the examples listed above usually are not exhaustive and are supposed to be illustrative.
What do LCAs estimate?
LCAs transcend simply evaluating a product’s carbon footprint to incorporate matters comparable to water consumption, vitality demand, useful resource depletion, waste technology, and air pollution. Let’s take the instance of a seemingly easy T-shirt to discover an instance of what may 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 hundreds of liters of water, with extra water used for dyeing, washing, and cleansing the shirt over its lifetime.
Main Power Demand (Power consumption): LCAs consider the vitality assets used to provide, distribute, and energy a product. For a T-shirt, this consists of 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 may ultimately 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 could be a highly effective software for driving innovation and lowering environmental influence.
They will provide tangible advantages for companies aiming to satisfy their sustainability targets. By figuring out essentially the most resource-intensive phases of a product’s life, corporations can goal environmental “hotspots” and implement modifications comparable to utilizing renewable vitality to energy manufacturing websites or switching to extra sustainable supplies that scale back their general influence. These insights can drive innovation, enabling the design of merchandise which might be extra energy-efficient, sturdy, and round with diminished resource-intensiveness and environmental influence.
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 choosing elements, course of steps or disposal varieties. By integrating LCAs early within the design course of, corporations can enhance sustainability outcomes.
Publishing LCA outcomes helps to boost company transparency and help environmental reporting. Sharing these studies builds belief with clients, workers, buyers, and different stakeholders, whereas making certain compliance with international 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 decoding the outcomes to help initiatives like net-zero targets and round product design.
LCAs comply with globally accepted requirements, such because the Worldwide Group for Standardization’s (ISO) 14040 and 14044. There are different requirements which might be 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 decrease the environmental influence of our merchandise.
Lately, we introduced that Cisco has made these assessments publicly accessible, sharing LCAs for quite a lot of our merchandise on the Sustainability Assets part of our web site. Cisco has already accomplished 23 LCAs throughout 8 enterprise items previously two years and plans to publish extra assessments throughout key product traces in 2025. Sharing these outcomes helps transparency and demonstrates our dedication to measurable progress.
Whereas many expertise corporations publish LCAs, Cisco is likely one of the first to provide them for networking tools, comparable 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 turn into accessible.
LCAs are a part of how we method sustainability holistically. LCA information helps our round design technique— to develop merchandise and assets which might be reused, repurposed, and saved in circulation for so long as doable. By evaluating every little thing from materials sourcing to end-of-life disposal, we achieve vital insights that information our product design and innovation.
