Sam Gill

Environmental Investment Organisation


Sam Gill is an environmental entrepreneur whose vision is to change the way money is invested in companies. After starting his career at Google, Sam decided to combine his passion for entrepreneurship with his immediate concern for the climate crisis. Taking the spirit embodied by Google - that by bringing together smart, motivated people, anything is possible - Sam began developing the Environmental Tracking concept.

Since 2010 Sam has led the Environmental Investment Organisation, a not-for-profit research body to become the first and only organisation in the world to produce an annual series of public Carbon Rankings, scoring the world’s largest listed companies by their greenhouse gas emissions and disclosure. These Environmental Tracking Carbon Rankings are designed to pave the way for a series of stock market indexes, based on the rankings, which redirect capital away from the most polluting companies towards the cleanest, most efficient.

In 2014 with support from the European Commission’s Climate KIC accelerator programme, he founded ET Index Ltd which is designed to commercialise and develop the Environmental Tracking Index Series, with a view to making it available to investors later in the year. Sam is author of Environmental Tracking 3.0, serves on the Board of a human rights NGO, and mentors several start ups.
