In response to growing global awareness of environmental challenges, the international community has developed innovative approaches to quantify and reduce our impact on the planet. This evolution has led to the creation of precise tools for analysis and action.
One of the most recent methods is Life Cycle Assessment (LCA), which is now governed by two standards: ISO 14040 and ISO 14044. These standards define both the principles and the guidelines for conducting an LCA. The standardized LCA approach assesses a product’s environmental impacts from the extraction of raw materials for its manufacture through to the end of its life.
Interview with Thomas Deleau, a faculty member and researcher at the RAPSODEE UMR 5302 center at IMT Mines Albi, on the topic of solid production via spray drying.
Thomas Deleau teaches in the PRINEC Advanced Master's® program—Processes and Resources for Circular Economy Engineering—where he leads a course module focused on learning how to conduct a life cycle assessment (LCA) of a product or service.
In what context were ISO 14040 and ISO 14044 developed?
In the 1970s, environmental concerns began to emerge. Particular attention was focused on greenhouse gas emissions, primarily carbon dioxide. But CO2 is just one component of the ecological footprint, among many other factors. The LCA environmental assessment method is more comprehensive. It emerged around the same time and evolved into a benchmark approach, eventually leading to its standardization. Its uniqueness stems from the fact that it quantifies environmental impacts and incorporates the concept of the life cycle. The impacts of the subject under study are measured “from cradle to grave,” or “from cradle to cradle” within the framework of circular economy approaches.
What about the goal of “net-zero emissions” by 2050?
By 2050, France, along with other countries, has set a goal of reducing its net greenhouse gas emissions to zero. This ambitious goal requires drastically cutting our current emissions and offsetting any remaining emissions. Beyond natural sinks such as oceans and forests, there are two main methods for offsetting them:
- Natural solutions, which rely in particular on vegetation-based approaches, such as reforestation or the restoration of natural ecosystems.
- Technological solutions currently under development, which utilize industrial capture processes, such as carbon capture and storage technologies.
Furthermore, when calculating an entity’s emissions—and even more so when comparing them—it is necessary to consider the entity’s entire lifecycle and express it using a common metric. This is the fundamental principle of the ISO 14040–14044 LCA methodology. According to this analysis, taking the example of developing carbon-free alternatives, how can we speak of zero emissions?
Is the LCA method a universally accepted standard in research?
In fact, LCA serves as a means of communication among researchers. It is a widely used, multi-criteria, quantitative tool. It requires a large amount of data—which is sometimes unavailable—and therefore involves the use of value scales. However, the results are scientifically comparable. In research, an LCA phase is incorporated into all project development processes. The RAPSODEE training and research center conducts studies in partnership with companies. In collaboration with Eco-Tech Ceram, it has carried out a life cycle assessment (LCA) of a thermal storage system designed to recover waste heat, specifically for the company’s Eco-Stock(r) systems. The objective was to assess the environmental impacts of the heat generated, compared to a conventional natural gas facility without waste heat recovery. The results showed a significant environmental benefit, with approximately 500 tCO2eq avoided each year, and an energy payback period of a few months (over a system lifespan of approximately 20 years).
Does the implementation of ISO 14040 and ISO 14044 meet a growing demand from businesses?
In order to better integrate environmental considerations into their decision-making, companies are increasingly seeking engineers capable of conducting a Life Cycle Assessment (LCA) in accordance with ISO 14040 and 14044 standards. Although there is no legal requirement to use this tool, companies are interested in it to anticipate future regulations and gain a competitive edge. LCA is often combined with a technical-economic analysis, which helps identify potential cost savings throughout the production chain—whether in terms of raw materials, energy, transportation, or waste. It also promotes innovation and product improvements in a highly competitive market. It can also aim to improve their communication by meeting consumers’ environmental expectations. LCA is thus a valuable tool for companies committed to eco-design and sustainable development.
As a valuable educational opportunity, during the "LCA, Industrial and Territorial Ecology" module, students in the PRINEC Specialized Master's® program study in detail the various tools used for environmental assessment and life cycle analysis. They learn the four main steps involved in conducting an LCA in accordance with ISO 14040 and apply them in practice using specialized software.
Overall, the interdisciplinary Master’s program equips students with the essential tools and knowledge to transform their understanding of supply chains and actively contribute to the development of the emerging circular economy.
