The Responsibility100 Index

A ranking of the FTSE 100 companies on their commitment to key social, environmental and ethical objectives, inspired by the UN Sustainable Development Goals

Holding companies to account

In 2015, the UN published the Sustainable Development Goals (SDGs). 

They are comprised of 17 individual targets spanning a wide range of topics from poverty and inequality to climate change and biodiversity.

The Responsibility100 Index, developed by Tortoise Intelligence, has been established to examine how much each of the FTSE 100 companies are doing to ensure a safe, fair and sustainable world.


Based on minor changes to our methodology and further consultation with companies on their data, we have updated the ranking of the Responsibility 100 Index. The latest rankings below are updated as of March 2020.

For more information see our methodology report.

It is possible to sort the results by a company’s ‘Talk’ score – the extent of their commitment – or their ‘Walk’ score – the extent of their actions. The ‘Gap’ measures the distance between these two scores. The rankings are as follow:

Insights report

Using the R100 index, we can track and assess companies’ strengths and weaknesses in contributing towards a more sustainable future. 

Our quarterly insights report offers more insights into the rankings and movements, as well as deep-dives into each of our pillars: Poverty & wellbeing. Equality. Climate. Education & Skills. Partnership. Justice. Good Business. 

Our latest report from March 2020 reveals:

  • Why Unilever, the owner and manufacturer of over 400 household brands from Ben & Jerry’s to PG Tips to Dove, has maintained its number one position in the Index. 
  • That companies in the pharmaceutical and financial sectors are the highest ranked, while those in travel and extractive sectors rank lowest.
  • That transparent reporting can make all the difference: whereas the top 10 performers in the R100 reported on 80% of our indicators, the bottom 10 reports on less than 50%.
  • That the FTSE 100 emitted 416 million tonnes of greenhouse gas emissions in their last reporting year.
  • That not one of the FTSE 100 currently publish data on the representation of LGBT+ and disabled people at a senior management level – or their pay gaps.

Our approach

The Responsibility100 Index uses data from a range of sources; including non-governmental organisation research, annual and sustainability reporting, web-based searching and information from regulatory bodies.

The indicators that comprise the Index have been selected with the aims of:

  • Reflecting publicly-available information rather than proprietary sources
  • Speaking to the 2030 Sustainable Development Agenda and the various targets that it sets
  • Providing a comprehensive portrait of each company according to the available data in order to establish comparability
