One room. Every calculator.
Every standard. Every regulator.
A curated directory of the carbon-accounting infrastructure that governs the construction industry. Calculators, standards, certifications, regulators, scientific bodies, datasets, and active legal cases — laid out together so the divergence between them is visible. None of these organisations is affiliated with this site.
The directory is organised by function. Within each section, entries are listed alphabetically. Every entry carries a one-line description of what the organisation actually does. Where an entry's relationship to the DRL framework is direct, it is noted in italics at the end of the description.
The free public-access calculators
These are the tools an architect, engineer, or specifier sits in front of when they make a material decision. Each implements a particular standards regime. The DRL Corrected Ledger uses these calculators' published outputs as the baseline for recomputation.
Building Transparency / Carbon Leadership Forum. Free North American database of EPDs. Widely used in U.S. specification practice. Implements EN 15978 boundary.
Athena Sustainable Materials Institute. North American whole-building LCA tool. Source of the Brock Commons EBD on the Corrected Ledger.
BRANZ / MBIE. New Zealand's national construction-materials carbon repository. Subject of Codex Section 7.4 worked example.
BRANZ. Early-design comparator tool, paired with NECO₂. The interface where the EN 15978 boundary becomes visible to a practitioner.
Inventory of Carbon and Energy. UK academic database widely cited in early-design embodied carbon assessment.
WoodWorks Wood Products Council. Industry-funded LCA and carbon calculators distributed free to architects. Source of the T3 Minneapolis disclosures on the Corrected Ledger.
Commercial whole-building LCA platform used widely in Europe. Implements EN 15978.
Revit-integrated whole-building LCA tool widely used in North American architectural practice.
The standards that define the boundary
These are the standards that decide what gets counted and what does not. The DRL framework is, in substantive terms, an argument about where these standards have set the line.
The international LCA standard. Defines life cycle assessment methodology globally. Origin of the biogenic-zero accounting convention.
Sustainability in buildings — Environmental product declarations. Assigns the LULUC characterisation factor of zero to certified "sustainably managed" forestry. The off switch, in the auditor's voice.
European standard for whole-building LCA. The standard most national building LCAs implement. Excludes B1 by methodological choice.
European standard for EPDs of construction products. The product-level companion to EN 15978.
Technical Committee for environmental management standards. The committee that produces ISO 14040/14044.
Sustainability in buildings and civil engineering works. The committee that produces ISO 21930.
Greenhouse Gas Protocol — the most widely used corporate emissions accounting framework. Scope 1 / 2 / 3 definitions used in nearly every ESG disclosure.
University of Washington-based research collaborative. Authors of the Embodied Carbon Reduction Toolkit and a major influence on North American embodied-carbon practice.
The bodies that issue the labels
These are the third-party schemes that issue the certifications referenced inside the standards. FSC and PEFC — between them — produce the "sustainably managed" designation that ISO 21930 then translates into a LULUC characterisation factor of zero.
International forest certification body. Founded 1993. One of two certifying bodies whose label switches the LULUC factor to zero under ISO 21930.
International umbrella for national forest certification schemes including SFI (US/Canada) and CSA (Canada). The other certifying body whose label switches the LULUC factor to zero.
North American forest certification standard. Industry-backed. Subject of an active Competition Bureau complaint filed by Ecojustice and seven other Canadian environmental organisations.
Leadership in Energy and Environmental Design. U.S. Green Building Council. The dominant North American building-level sustainability rating system.
Building Research Establishment Environmental Assessment Method. UK-origin building rating system widely used in Europe.
Corporate emissions target validation. Used widely in ESG investment screening.
Sustainability reporting standards. Most widely used corporate sustainability disclosure framework worldwide.
IFRS-affiliated body developing global sustainability disclosure standards (IFRS S1 and S2). Increasingly influential post-2024.
The agencies that hold the pen
Government agencies, international bodies, and intergovernmental panels that produce the regulatory framework within which the standards operate.
The scientific authority cited by every national greenhouse gas inventory. Source of the methane GWP100 value (27.9, AR6) used throughout the DRL framework.
UN Framework Convention on Climate Change. The treaty under which all national GHG inventories are submitted. Land Use, Land-Use Change and Forestry (LULUCF) reporting requirement.
U.S. federal environmental regulator. April 2018 statement of policy on forest biomass — the document that classifies biomass combustion as carbon-neutral while stating, in its own text, "this is not a scientific determination."
U.S. federal forestry agency. Administers the Wood Innovations Grant Program ($93M+ 2015–2025 + $95M FY2026 announced).
U.S. corporate disclosure regulator. Climate disclosure rule status varies; relevant to scope-3 disclosure of construction-sector emissions.
European Union regulation on deforestation-free products. The first major regulatory instrument that requires landscape-side accounting of timber product origin.
European Union restriction on environmental marketing claims. Comes into force September 2026. Restricts use of "carbon neutral" and similar in EU advertising without rigorous substantiation.
New Zealand environmental regulator. Author of the April 2024 GHG Inventory Snapshot quoted in Codex Section 7.4: "afforestation causes an increase in net emissions in the year of planting."
UK environmental regulator. Publishes the UK greenhouse gas inventory and conversion factors widely cited in corporate carbon accounting.
Intergovernmental energy and emissions analysis body. Construction sector emissions analyses are widely cited.
Where carbon has a price
Government-administered carbon-pricing schemes. The price-side context for the disclosure-side argument the DRL framework is making.
European Union Emissions Trading System. The world's first and largest carbon market.
New Zealand Emissions Trading Scheme. Includes forestry. Diagnostic context for Codex Section 7.4 and the Te Uru Rakau companion paper in preparation.
Global mapping of carbon pricing instruments. The reference for cross-jurisdictional comparison of carbon prices.
Verified Carbon Standard. The largest voluntary carbon market standard. Subject of multiple greenwashing class actions including Dib v. Apple Inc.
Where the money is recorded

Where the underlying science is done
Research institutes, scientific bodies, and peer-reviewed journals that produce the underlying carbon science the DRL framework draws on. These are not advocacy organisations; they are the data producers.
Independent research institute. Global Forest Watch. Co-authors of Searchinger/Peng (Nature 2023) on the carbon costs of global wood harvests.
Peer-reviewed scientific journal. Publication venue for the Searchinger/Peng 2023 paper and the subsequent Sohngen/Baker/Favero critique and Searchinger/Berry/Peng reply in Nature 646.
