From early phase, high-level decisions to detailed component assessments

One Click LCA provides data for different types and levels of assessments. Here’s a summary, and below we drill down to show the value that each one brings.

Carbon Heroes benchmarks

These are A-G carbon intensity ratings by building type and country/region. They allow building performance to be compared against typical buildings on the market on a scale of A-G with the kg CO2e per each rating level.

Carbon Designer 3D regions

With these regionalized building archetypes and associated construction practices you can generate a baseline building of any type for any country or region. This uses the Carbon Designer 3D tool.

One Click LCA also supports construction practice templates to compare materials. They contain all the elements and systems needed for a building of a given type, and are applied using a building sizing engine. They allow you to compare the different baseline carbon impacts for specific scenarios, for example, comparing  a five story apartment building in Portland, whether made with ready mix concrete or mass timber. The local archetypes have been developed in cooperation with local designers and engineers.

You can also create your own material templates to automatically apply your own construction methodologies.

Construction assemblies or all-in-one construction elements

Assemblies in One Click LCA are all-in-one systems or construction elements that you can use to speed up your assessments and reduce the risk of errors. Assemblies contain all the materials, layers, components and sizing rules needed to calculate scenarios such as: the electrification of a data center per m2 floor area; one meter of road barrier; or one square meter of insulated brick wall in one single choice. Almost all assemblies use generic data only. You can substitute the generic materials for ones from your preferred suppliers, and you can also create your own assemblies.


Products in One Click LCA are products purchasable and installable from a specific supplier, or in case of generic data, from a typical supplier (if no supplier is yet retained). These range from paints and furniture to bricks, concrete connectors and innovative materials. This category of data is the largest by volume. You can also add your own private product data.


Processes in One Click LCA are processes such as heat supply, transportation, operating a machine, or recycling a material. Processes are used to make an assessment complete and to include all required activities to deliver and operate the asset. You can also add your own private processes.

Raw materials

Raw materials in One Click LCA are raw materials or components used to manufacture products, such as nitric acid or LCD display. Raw materials are required for performing assessments of products, for example for creating new Environmental Product Declarations or new generic datasets.You can also add your own data. This type of data is not suited for construction project level assessments and hence is not available in construction project LCA tools.

From mechanical design to civil engineering

One Click LCA is committed to providing high quality data for every design discipline. The below summarizes the main types of data you can find in One Click LCA. Almost all data can be accessed in the global tools, including Net Zero Carbon tool and Life-Cycle Carbon Global tool.


One Click LCA's database of architecturally relevant datasets is in the tens of thousands. Data is provided for all types of materials and construction systems used and specified by architects for any building type.

Civil engineering

In addition to tens of thousands of concrete datasets and thousands of steel and cement datasets, One Click LCA's civil engineering relevant database includes also several thousand additional datasets for infrastructure-specific needs such as soil stabilization, infrastructure, road, rail, bridge and geotechnical systems, pavements, soils and aggregates as well as various types of piping and infrastructure solutions. This database is available, among others, in our PAS 2080 tools.

Energy & facade design

One Click LCA's energy and façade relevant database consists of several thousand glazing, façade, cladding, window and door datasets, insulation datasets and all envelope related datasets.

Interior design

One Click LCA's interior design relevant global database consists of several thousand datasets, covering floor, wall and ceiling finishes, internal walls and partitions, furniture and flooring for all different types of buildings.

Mechanical & electrical design

One Click LCA's MEP relevant global database consists of several thousand datasets, covering cabling, lighting, water handling and piping, ventilation and air conditioning, heating and renewable energy generation, elevators and communication systems.

Landscape design

One Click LCA's landscape-relevant global database consists of several thousand datasets, comprising datasets for modelling the impacts of vegetation, as well as soils, masses, pavements and external constructions.

Structural design

One Click LCA's structural engineering database consists of tens of thousands of datasets for all types of structural solutions from bio-based to concrete, steel and lightweight construction.

If any qualifying, available data that exists is missing, customers can request it to be integrated for free.

Where a certain region is not well served with specific data for, say, electrification, One Click LCA’s manufacturing localization process enables users who so wish to adjust the datasets’ environmental performance to reflect local manufacturing more accurately.

From worldwide generics to manufacturer and product-specific EPDs

One Click LCA covers all levels of data granularity to support you with the accurate information you need in various project phases. When you select a product with an EPD, you can be confident that you will find the EPD in One Click LCA. But when your supplier or product does not have an EPD, or if you did not choose a supplier yet, you have an extensive library of high quality generic data at your disposal.


The database designed to help you find everything

All of the data is pre-checked for you. One Click LCA runs an extensive checking process against every datapoint it integrates, and if anything is missing, a warning to the datasets is added or these are blacklisted. High value metadata is also added to the datapoints, such as the type of third party verification performed to the dataset before publishing. This ensures you know what you get. 

One Click LCA incorporates a broad set of metadata in every EPD, in addition to information incorporated in the EPD itself. This includes information such as the typical product service life, typical end of life processing, and the carbon benchmark of the product relative to others in its category, and background information. All of this information is made available to users via data cards.
