External tools and resources

These are the key external tools and resources referenced in the Modules of the JARGONFREE Compass for Sustainable Contracting.

ISO ESG Implementation Principles (IWA 48)

The International Organization for Standardization (ISO) has published ESG Implementation Principles (IWA 48), which provide guidance for integrating environmental, social, and governance considerations into organizational strategy, governance, and decision-making. The document outlines key principles and practical approaches for embedding sustainability into management systems and business practices. It is currently available free of charge on ISO’s website, although ISO has indicated that a revised version is under development.

OECD Due Diligence Guidance

The OECD Due Diligence Guidance helps businesses understand and implement due diligence for responsible business practices. The guidance also aims to foster a shared understanding of responsible business conduct among governments and stakeholders.

OECD Due Diligence Checker

The OECD Due Diligence Checker is an anonymous, browser-based self-assessment that helps companies compare their current due diligence practices with internationally recognised standards for responsible business conduct. It starts with 13 introductory questions for a high-level snapshot, with optional, more detailed question sets aligned to the typical six-step due diligence cycle.

The Chancery Lane Project

The Chancery Lane Project (TCLP) provides a free, open-source library of climate-aligned contract clauses accompanied by practical guides and playbooks designed to help embed climate considerations into commercial contracts.

The Responsible Contracting Project (RCP)

The Responsible Contracting Project (RCP) offers a toolkit with model contract clauses, explainers, and tools aligned with the UNGPs and the OECD Guidelines. Resources cover different sectors and geographic locations. Examples of model contractual clauses include

The European Model Clauses (EMCs), drafted by the European Working Group composed primarily of European legal experts from practice and academia. The EMCs are designed to align with the CSDDD.
The Model Contract Clauses to Protect Workers in International Supply Chains (MCCs) 2.0 that were developed by a Working Group of the American Bar Association’s Business Law Section. The model clauses are intended for buyers located in the United States.

Plain: Written in direct, accessible language
Well-designed: Structured logically with clear formatting

Relational: Framed with the right audience in mind

WorldCC Foundation Contract Design Pattern Library

These patterns are intended to help make contractual information clearer, easier to navigate, and more usable.
