Life Cycle Assessors analyse the environmental impact of products and processes from the point where raw materials are extracted all the way through to disposal. They collect data, build models, and produce reports that help organisations understand and reduce their environmental footprint.
If you’re passionate about sustainability, comfortable working with data, and enjoy translating complex findings into clear recommendations, this career sits at an important intersection of science and strategy.
What skills do I need as a Life Cycle Assessor?
- Analytical & data-driven
- Strong research skills
- Environmental knowledge
- Clear & concise communicator
- Critical thinker
- Methodical & thorough
- Proficient in modelling software
- Collaborative & consultative
What do Life Cycle Assessors do?
At the start of a project, you define the scope of the assessment, determining which stages of a product or process you’ll be examining and what data you need to collect. This scoping phase is important because life cycle assessments can be enormously broad, and setting clear boundaries early shapes everything that follows. You’ll gather data from a range of sources, including manufacturers, suppliers, scientific databases, and industry reports, and begin building a picture of where the environmental impacts are concentrated.
The core of your work involves entering that data into specialist modelling software and running analyses across a range of environmental indicators, including carbon emissions, water use, energy consumption, and waste generation. You interpret the outputs, identify hotspots where impacts are highest, and develop findings that are accurate, defensible, and useful to the people who need to act on them. Producing clear, well-structured reports is a significant part of the role, and the ability to communicate technical results to non-specialist audiences is something you’ll use constantly.
Alongside the technical work, you’ll regularly consult with design teams, engineers, procurement managers, and clients to help them understand your findings and apply them to real decisions. Periodic tasks include staying current with evolving methodology standards, contributing to green certification processes, and supporting organisations as they work toward environmental targets. Some Life Cycle Assessors develop deep expertise in particular industries or material types, such as construction, packaging, or food systems, building a reputation in a specific area over time.
What kind of lifestyle could I expect?
Life Cycle Assessors work for environmental consultancies, sustainability-focused research organisations, government agencies, and large corporations with dedicated sustainability functions. Some roles sit within product design or manufacturing companies where LCA is used to guide material and process decisions. The field is relatively small but growing steadily as environmental reporting requirements become more rigorous across industries.
The work is primarily office-based, with most time spent at a computer running models, analysing data, and writing reports. Client meetings and site visits occur periodically but are rarely the dominant part of the job. Many roles offer flexibility, with remote or hybrid arrangements common in consultancy and research settings.
Hours are generally standard, with busier periods tied to project deadlines or reporting cycles. The role is mentally demanding, requiring sustained concentration and careful attention to detail over long stretches. Salaries are average at entry level and have strong potential to grow above average as you build expertise and take on more complex or senior projects. The field is experiencing strong growth, driven by increasing regulation around environmental disclosure and a growing expectation that organisations can account for the full impact of what they make and sell.
How to become a Life Cycle Assessor
- Complete a relevant degree: You’ll typically need a bachelor’s degree in environmental science, engineering, chemistry, or a related field. Some Life Cycle Assessors come from backgrounds in product design or sustainability, particularly if they’ve developed strong quantitative skills alongside their environmental knowledge.
- Develop your technical skills: Familiarity with LCA methodology and specialist software such as SimaPro or OpenLCA is important and increasingly expected by employers. Many universities introduce these tools during undergraduate study, but pursuing additional online training or self-directed learning can give you a real advantage when applying for early roles.
- Gain entry-level experience: Look for graduate roles, internships, or research assistant positions with environmental consultancies or organisations that conduct LCA work. Early roles often involve data collection and model building under supervision, which is where you develop the practical judgement that comes with handling real datasets.
- Build your expertise and professional profile: As you gain experience, focus on developing depth in particular industries or impact categories. Joining professional networks in the sustainability and environmental science space, contributing to published research, or pursuing postgraduate study can all help you build credibility and open up more senior opportunities.
From here, you could progress to senior assessor or project lead roles, move into environmental consulting more broadly, or take on advisory positions helping organisations shape their sustainability strategy. Some Life Cycle Assessors move into policy or standards development, contributing to the frameworks that govern how environmental impact is measured and reported across industries.
What can I do right now?
If you’re in high school and interested in working as a Life Cycle Assessor, here are some practical steps:
- Focus on maths and science subjects, particularly chemistry, biology, and environmental science, as these build the quantitative and analytical foundations the role relies on
- Start exploring the concept of life cycle thinking by researching the environmental impact of everyday products, from how they’re made to what happens when they’re thrown away, to develop the systems-level thinking the role requires
- Look for volunteer opportunities or work experience with environmental organisations or sustainability-focused businesses to get a feel for how environmental data is used in real decisions
