EO100™ Standard Development & Review

Information for Producers/Operators:

Companies that commit to implementing the EO100™ Standard before the publication of the revised Technical Supplements will have one year from the date of publication of the Supplements to implement any additional requirements contained in the updated version. Companies with sites certified to the current EO100™ Standard will be expected to demonstrate conformance with any additional requirements during their next verification assessment or re-certification assessment that falls in the calendar year following one year from the date of publication of the revised standard.


Equitable Origin is a stakeholder-based system and our commitment to continuous consultation with communities, civil society, international NGOs, government agencies and businesses informs everything we do.

Equitable Origin’s EO100™ Standard for Responsible Energy Development was conceived and developed with stakeholders engaged in decision making from its inception in February 2009 to its launch in 2012. Consultation with diverse stakeholders will continue to be an integral component of all revisions and updates to the Standard.

The first ‘consultation draft’ of the EO100™ Standard was developed by Equitable Origin, in collaboration with four Indigenous Peoples’ organizations, environmental and development NGOs, oil and gas companies and service providers, and local government agencies in the Amazon basin. Technical support was provided by consultants from The Dragonfly Initiative, One World Standards and Colibri Consulting. The EO100™ Standard ‘consultation draft’ was made publicly available in December 2009 and, along with subsequent versions of the standard, was used in consultations with stakeholders through a series of workshops, a public comment period, international consultations, and a formal Consultation Committee and Reference Group.

Engagement of NGOs, development finance institutions, academics, and standard-setting bodies began in 2010. We held workshops in major cities in the Latin American region, including Lima, Quito and Bogotá. EO also introduced the EO100™ Standard to industry specialists at presentations in Washington D.C., Paris and Manaus, Brazil. We sought the advice of international NGOs including The Nature Conservancy, Wildlife Conservation Society, Conservation International, the International Union of Conservation for Nature, and the Rainforest Foundation.

Equitable Origin held a public comment period from June to November 2010 and launched an online public consultation tool and tutorial to capture comments and suggestions. We collected, analyzed and recorded over 1,300 comments from communities and Indigenous Peoples’ organizations, industry, academia, NGOs, and governments. Equitable Origin staff responded to all of those who had submitted comments to explain how their contributions would be treated. These comments from the public, along with feedback from consultation workshops, were incorporated into a revised version of the EO100™ Standard that was made public in November 2010.

In February 2011, a formal Consultation Committee was formed with representatives from four stakeholder groups: energy producers and industry service providers, government agencies, local and indigenous communities, and environmental and development NGOs and academics. To communicate the deliberations of the Consultation Committee and to provide a conduit for feedback, an open-to-all Reference Group was established. The Consultation Committee provided recommendations for revisions to the draft Standard throughout 2011. The final version of the EO100™ Standard was approved by the Board and published in February 2012.

The EO Standards Technical Committee reviewed the feedback and proposed final revisions to the EO Board in late 2021.

In 2017, EO completed the process of updating the EO100™ Standard for Responsible Energy Development.

Between 2009 and 2012, the EO100™ Standard was developed in consultation with a broad range of stakeholders affected by energy development. We learned a number of lessons through our work with energy developers to implement the EO100™ Standard; through our efforts to develop policies, procedures and training for independent consultants and auditors; and through feedback we received from users of the Standard and from other interested and affected stakeholders.

To address these developments, Equitable Origin began a comprehensive review of the EO100 Standard with the EO Standards Technical Committee in 2014. We completed the review in 2016 and published a revised version of the EO100™ Standard in early 2017.
