Brightway2 is an open-source Python framework designed for advanced Life Cycle Assessment (LCA) modeling and calculations. It excels in handling large-scale LCA databases like ecoinvent, enabling efficient matrix-based computations, uncertainty analysis via Monte Carlo simulations, and scenario modeling. Primarily targeted at researchers and developers, it provides unparalleled flexibility for custom LCA workflows but requires programming proficiency.

One Click LCA is a cloud-based life cycle assessment (LCA) platform designed primarily for the construction and building industry, enabling users to evaluate the environmental impacts of projects from cradle-to-grave. It features a comprehensive database of over 50,000 materials and supports standards like EN 15804 and EN 15978 for compliant reporting. The software integrates seamlessly with BIM tools such as Revit and IFC, streamlining workflows for architects, engineers, and sustainability professionals.

Tally is a life cycle assessment (LCA) software tailored for the architecture, engineering, and construction (AEC) industry, integrating directly into design tools like Rhino, Grasshopper, and Revit. It enables users to rapidly quantify the embodied carbon and environmental impacts of building materials and assemblies using a database of verified Environmental Product Declarations (EPDs). Tally streamlines LCA workflows by providing real-time feedback during the design phase, making sustainability analysis accessible without requiring specialized LCA expertise.

EC3 (Embodied Carbon in Construction Calculator) from buildingtransparency.org is a web-based tool designed for calculating the embodied carbon footprint of building materials and assemblies throughout their life cycle. It leverages a vast database of verified Environmental Product Declarations (EPDs) to enable users to model projects, compare alternatives, and generate reports for low-carbon design. Primarily targeted at the AEC industry, it supports cradle-to-gate assessments with some cradle-to-grave extensions via partnerships.

GREET (Greenhouse gases, Regulated Emissions, and Energy use in Transportation) is a life-cycle analysis tool developed by Argonne National Laboratory for evaluating energy consumption, greenhouse gas emissions, and air pollutants across vehicle-fuel pathways. It supports well-to-wheel and cradle-to-grave assessments for a wide range of technologies, including conventional fuels, biofuels, electricity, hydrogen, and advanced vehicles like EVs and FCEVs. The software includes downloadable Excel models and a web-based interface (GREET.net), backed by an extensive, peer-reviewed database.
