Life Cycle Assessment (LCA)

We Speak


Years of Experience in LCA

We believe that Life Cycle Assessment (LCA) can contribute to a better industry, manufacturing processes, supply chain, and environment.

What is LCA?

Life cycle assessment (LCA) is a well-established method for assessing the environmental impacts of a product or service over its entire life cycle, from raw material extraction through production, use, and disposal. Life cycle assessment can be used to compare the environmental impacts of assorted products or to evaluate the relative importance of different stages in the life cycle of a single product. Life cycle assessment is a complex process, and there are many different ways to approach it. In general, however, an LCA begins with an inventory of all of the inputs and outputs associated with a product or service. These inputs and outputs are then quantified in terms of their environmental impacts, such as greenhouse gas emissions, water use, or waste generation. The resulting information can be used to assess the overall environmental impact of the product or service and identify opportunities for improvement.

Types of LCA Studies
  • Screening LCA: The overall environmental performance of a product, service, or manufacturing process can be estimated using screening LCA with LCA data, known as Life Cycle Inventory (LCI) databases comprising thousands of processes and thousands of emission factors for an extensive list of pollutants or emissions. This study provides rough estimates and evaluations for several impacts like eutrophication, acidification potential, human toxicity potential, climate change potential, etc. The purpose is to gain insights into what adverse effects exist in production processes. Hence, we know to estimate the negative or positive impacts lies on the company when it comes down to choosing which products will affect them positively. In other words, Screening LCA helps get a "snapshot" of the overall environmental load of a system or products, services, or technologies.
  • Product LCA: An analysis and evaluation that looks at the environmental performance from the cradle to the grave of individual products or technologies. This includes everything involved in its production cycle- the extraction process until it reaches our current disposal capabilities or ends them there instead of being disposed of improperly, which can cause some problems down along this line too, such as pollution from pollution landfilling or incineration, or hazardous waste.
  • Comparative LCA: The life cycle analysis of the "Comparative LCA" is an evaluation process that considers the environmental impacts of all aspects and stages to create an accurate accounting for what it will do over time. A common type of LCA study would be when you compare two different products or technologies, such as one technology with another; however, there are other cases where this method can also apply (e.g., comparing development routes).
  • The output tone should still maintain its professionalism but now sounds more engaging than before

Professional LCA Training

DEISO LCA Training Programs.


The number of people participating in LCA training programs is growing worldwide, with an increasing percentage coming from outside Japan for remote training. This trend can be attributed to many factors, including convenience for participants and their employers who want access even when they’re not available at physical locations – but it also reflects how severe environmental concerns have become global-scale issues that require developing skills and utilizing the LCA method.
