Welcome to the Circular Ecology Knowledge Base, a central hub for tools, guidance, definitions, and resources to support your sustainability work.
Explore the sections below to find quick explanations, data sources, articles, updates, and links to our most useful materials. New content is added regularly as standards evolve and new tools are released.
The Inventory of Carbon and Energy (ICE Database) is an embodied carbon database for building materials. Downloaded by over 50,000 professionals globally, the ICE Database appears in countless reports, journals, books, embodied carbon footprint calculators, and more.
The database helps users estimate cradle-to-gate emissions and understand the carbon implications of different design choices. Its ongoing development ensures that the data remains robust, up-to-date and aligned with the needs of industry.
We have developed multiple practical tools and calculators designed to support accurate and consistent sustainability reporting. This area includes a range of simple, reliable tools that help organisations estimate emissions, understand their environmental impacts and build confidence in their carbon data.
Among these resources is Circular Ecology’s free Scope 1 & 2 carbon footprint calculator, which offers an easy-to-use way to quantify direct and energy-related emissions using clear methods and up-to-date emission factors. These tools are intended to help users make informed decisions, streamline reporting processes and strengthen internal understanding of carbon performance.
The Sustainable Development area explores the principles that guide long-term environmental responsibility and resource efficiency. It introduces the ideas behind circularity, low-carbon design, responsible sourcing and environmental stewardship, setting out the foundations that underpin modern sustainability practice.
By outlining these broader concepts, the resource helps organisations understand how climate and resource considerations connect to strategy, procurement, product development and day-to-day decision-making.
Our glossary provides clear, straightforward explanations of key concepts, terms and data points used across carbon accounting, LCA, environmental reporting and sustainability more broadly. Many topics in this field can appear complex or inconsistent, so this resource aims to offer dependable definitions and factual context that make technical language more accessible.
Alongside the glossary, this area also includes Circular Ecology’s environmental fact cards, concise, easy to understand summaries that highlight important sustainability figures, concepts and insights. These cards distil technical information into simple, engaging snapshots that can be shared within teams, used in presentations, or kept as quick reference material to support learning and communication.
The Webinars and Video Recordings area offers on-demand access to presentations, talks and webinar sessions delivered by Circular Ecology. These recordings provide practical guidance, walkthroughs, case studies and explanations of emerging topics, allowing viewers to learn at their own pace.
The collection supports both introductory learning and deeper technical understanding, making it a useful resource for individuals and teams looking to build capability in carbon footprinting, EPDs, LCA and related subjects.
News & Articles offers commentary, insights and reflections on current developments across sustainability, carbon policy, and life cycle assessment practice. It highlights updates to datasets and methodologies, explores emerging trends, and provides explanations of shifting standards and industry expectations.
Through these articles, readers can gain a balanced understanding of both technical changes and their practical implications, helping them stay informed in a rapidly evolving landscape.
