Policies and approach

The Group’s environmental policy commits it to operating in a responsible, environmentally sound and sustainable manner at all times. It also recognizes that these responsibilities extend to the Group’s supply chain, processes and products and that these aspects of the business have both direct and indirect environmental impacts. The Group has pledged to achieve continuous improvement in its environmental performance and compliance with the law as the minimum standard.

Management Systems

The Group’s management of its environmental and climate change impacts has been developed at a local level to address the varying impacts at its Fine Chemical Plant in Hull, UK, the new R&D Center of Excellence (also located in Hull, UK), its research and development facility in Fort Collins, Colorado, US and across its various office facilities.

The Fine Chemical Plant has ISO 14001 certification and closely monitors its emissions, ground water and effects on local biodiversity in conjunction with the UK Environment Agency. These include regular testing of ground water samples and air quality to ensure that harmful contamination is not taking place through leaks, spills or fugitive emissions. It also conducts a program of ongoing improvements to enhance the Group’s approach over time. At all other sites, the Group conducts a variety of energy saving, reuse and recycling initiatives.


The Group has recorded no material environmental incidents (e.g. spills, emissions to air) during 2017.

Greenhouse gas emissions

This is the third year Indivior has comprehensively reported greenhouse gas emissions as a stand-alone entity. The baseline year for emissions reporting is 2015. The reporting period for emissions is consistent with Indivior’s financial reporting period, being the calendar year ended December 31, 2017.

Indivior has reported on all the emission sources required under the UK Companies Act 2006 (Strategic Report and Directors’ Report) Regulations 2013. These sources fall within the consolidated Financial Statements.

Indivior does not have responsibility for any emission sources that are not included in the consolidated Financial Statements. Indivior has also reported Scope 3 data, where it was available, that relates to transmission and distribution losses (52 tonnes of CO2e) and water supply (6 tonnes of CO2e). This assessment has been carried out in accordance with the World Business Council for Sustainable Development and World Resources Institute’s (WBCSD/WRI) Greenhouse Gas Protocol; a Corporate Accounting and Reporting Standard. This protocol is considered current best practice for corporate or organizational greenhouse gas (GHG) emissions reporting. GHG emissions have been reported by the three WBCSD/WRI Scopes. Scope 1 includes direct GHG emissions from sources that are owned or controlled by Indivior, such as natural gas combustion and Indivior owned vehicles. Scope 2 accounts for GHG emissions from the generation of purchased electricity, heat and steam generated off-site. Scope 3 includes all other indirect emissions. The method used to calculate emissions is the GHG Protocol Corporate Accounting and Reporting Standard (revised edition) using the location based Scope 2 calculation method, together with the latest emission factors from recognized public sources, including but not limited to, the Department for Environment, Food & Rural Affairs (DEFRA), the International Energy Agency, the US Energy Information Administration, the US Environmental Protection Agency and the Intergovernmental Panel on Climate Change.
