Life cycle assessment (LCA) can be quite expensive, costing between $30,000 – $50,000 or more per product depending on its complexity. The largest cost associated with conducting an LCA lies in the data collection and calculation, which LCA practitioners deem as the most difficult part of doing an LCA. However, embarking on a journey towards sustainability doesn’t have to break the bank or take forever. Here’s a guide on how to conduct faster and more cost-effective Life Cycle Assessments (LCAs) without compromising on quality.
1. Precise Scope Definition
Begin by clearly defining the scope of your LCA. Identify the specific goals, boundaries, and depth of your assessment. A well-defined scope prevents unnecessary data collection and streamlines the entire process.
2. Embrace Simplicity in Data Collection
Complex data collection can be a bottleneck. Opt for simplicity by focusing on essential data. Prioritize primary data sources, and whenever possible, utilize existing databases or industry averages to minimize the need for extensive, time-consuming surveys.
3. Reuse Prior Study Data and Templates
If you’ve already conducted an LCA for one product, don’t start the next one from a blank page. Similar products frequently share raw materials, manufacturing processes, packaging formats, or even suppliers, which means a large share of the background data, unit process mappings, and emission factor selections from a previous study can carry over directly. Building a template out of your first LCA — standard boundary definitions, a reusable bill-of-materials structure, common assumptions documented alongside their sources — turns each subsequent assessment into an exercise in updating and extending existing work rather than reinventing it. For companies with a product portfolio rather than a single SKU, this is often the single biggest lever for reducing per-product cost over time.
4. Upgrade Data Quality Incrementally, Not All at Once
Not all inputs to an LCA need the same level of precision. Spend-based data — estimating emissions from financial spend using industry-average factors — is fast and cheap to gather, but less precise than activity-based data drawn from actual quantities, supplier-specific factors, or metered consumption. Rather than attempting a fully activity-based model on day one, start with spend-based estimates across your full scope, then identify the categories that turn out to be emissions hotspots. Upgrading just those categories to activity-based data delivers most of the accuracy improvement of a full activity-based LCA for a fraction of the cost and time, since you’re only investing extra data-collection effort where it actually changes the result.
5. Automate Emission Factor Matching
Manually searching emission factor databases like ecoinvent or GaBi and mapping each purchased material or activity to the right factor is one of the most time-intensive parts of an LCA, and it’s also where human error creeps in. Automating this matching — using software that recognizes materials, processes, and activities from your data and proposes the correct factor automatically — removes the bulk of this manual lookup work. Analysts can then spend their time reviewing and validating matches rather than searching for them, which materially cuts the hours required per assessment without sacrificing methodological rigor.
6. Standardize Supplier and BOM Data Collection
A large share of LCA delays comes not from calculation but from chasing down usable data from suppliers, in whatever format each one happens to keep it. Standardizing your bill-of-materials (BOM) and supplier data-request templates — consistent units, consistent categories, a consistent set of questions — means data comes back in a form that’s ready to use rather than requiring cleanup and reformatting for every request. Over time, this also builds a structured, reusable dataset in-house, so future LCAs and Product Carbon Footprint (PCF) calculations across your portfolio draw on the same clean data foundation instead of starting each supplier conversation from scratch.
7. Leverage Sustainability Software
Investing in dedicated LCA software can significantly speed up the process. These tools often come with built-in databases, streamlined workflows, and automation features. While there might be an initial cost, the time saved and accuracy gained can outweigh the investment. Increasingly, AI-assisted tooling adds another layer of efficiency on top, handling emission factor matching, flagging data gaps, and surfacing hotspots automatically, so analyst time goes toward interpretation and decision-making rather than repetitive lookup work.
8. Data Sharing and Collaboration
Explore opportunities for collaboration within your industry. Sharing relevant data with other organizations or collaborating on joint LCA efforts can reduce costs for everyone involved. It’s a win-win situation that fosters a collective approach to sustainability.
9. Focus on Key Impact Categories
Identify the key impact categories that matter most to your product or process. Concentrating on these categories allows for a more targeted and efficient LCA. It streamlines data collection and analysis, saving both time and resources.
10. Continuous Improvement Loop
View LCA as an iterative process. Conducting LCAs regularly enables you to refine and improve your methods over time. Each cycle enhances efficiency and accuracy, creating a continuous improvement loop.
11. Training and Capacity Building
Invest in training your team or individuals responsible for LCA. A well-trained team can navigate the process more efficiently, ensuring that data collection and analysis align with best practices.
