In August 2018 Ethical Consumer received a response from Oxfam. Regarding its environmental reporting it stated two documents were referred to.

1. Oxfam Annual Report & Accounts 2016/17
This stated that it was committed to "reducing its environmental impact and in 2016–17, the carbon emissions from its UK-based activities decreased by 4% and were 3% below our 2011 baseline...Our total electricity consumption remained stable and was 5% below our 2011 baseline...To further accelerate our carbon reduction plans to help us meet our 2020 reduction targets we are currently undertaking a tender process with the aim of achieving full integration of the retail and recycling centre logistics and an upgrade of our fleet to more efficient models. Total distances travelled by air and associated emissions both increased by 5% on previous year."

2. Ethical and Environmental Policy (July 2018)
This applied to suppliers and stated that "its suppliers are not only expected as a minimum to comply with all applicable legislation and statutory requirements but also to demonstrate commitment to meet the following standards."
The following standards included: climate change, waste, materials, packaging, wood and forest products, energy, transport, conservation of biodiversity and water.

While Oxfam was considered to have demonstrated a reasonable understanding of its environmental impacts neither documents contained any environmental targets. As a result Oxfam received Ethical Consumer's worst rating for environmental reporting.

Questionnaire (29 August 2018)

In August 2018 Ethical Consumer viewed Oxfam's website for the organisation's wood and timber sourcing policy.
Two documents were viewed Ethical and Environmental Policy (July 2018) and GFTN-UK Forest Product Reporting Summary for 2013.
Oxfams policy covered all timber and timber-derived products. It also included clauses excluding illegal timber and a preference for certified sources. The company stated that it also used recycled wood / paper.
While Oxfam had provided a report from the WWF's Global Forest and Trade Network, Ethical Consumer viewed GFTN's current members and Oxfam was not listed. The report on its website dated 2013 stated that it used 60% of certified paper / timber however no updated figure was provided.
Without membership to GFTN and no recent figures provided on certified timber usage, Oxfam received a middle Ethical Consumer rating for its timber sourcing policy.
