The Zoological Society of London (ZSL) developed the Sustainable Palm Oil Transparency Toolkit (SPOTT) to provide information regarding the sustainability of oil palm operations to stakeholders and the public.

The SPOTT scorecard ranks the top palm oil companies according to approximately 100 sector-specific  indicators divided into several categories relating to:

• the availability and transparency of company reports
• efforts to adhere to the sustainability guidelines set out by the Roundtable on Sustainable Palm Oil (RSPO)
• a company’s landbank, environmental management and land development methods
• policies for zero burning and no planting on peat
• greenhouse gas emissions
• traceability of palm oil products

In October 2018 the group’s score increased to 70 per cent, from 67 per cent in 2017.  This increase reflects improvements in the presentation of data and clarification of certain company policies and has resulted in a ranking of 19^th out of 70 companies, compared with 16^th out of 50 participating oil palm companies in 2017.
