Our Commitment to Impact and Responsible Investing

Since our founding, a core tenet of Lime Rock New Energy’s approach to investing has been to invest in businesses that deliver net positive environmental benefits and broader societal impact.


The core impact metric that we track and report on for every investment is greenhouse gas emissions abated, and most specifically CO₂ emissions abated. LRNE works with each portfolio company to develop a comprehensive framework for measuring averted CO₂ equivalent and uses this data to report both annual and cumulative carbon abatement.

In addition to monitoring and measuring emissions-related impact, we also track and report on other critical impact metrics such as board and employee diversity and inclusion, and job creation at our investments. LRNE is dedicated to partnering with each investment to help expand the positive societal impact of the company.

Each investment is also mapped against the United Nations Sustainable Development Goals, not only at the high-level goal, but including individual SDG targets and indicators.

On an annual basis, LRNE gathers and synthesizes portfolio- and company-level impact performance as well as progress toward material ESG KPIs. This information is provided to our investors in our Annual Impact Report.

Our commitment to impact also extends to the broader investing community, and Lime Rock New Energy is proud to be a member or signatory of the following organizations:


The Principles for Responsible Investment

The Principles for Responsible Investment (PRI) is the world’s leading proponent of responsible investment. Supported by the United Nations, it works to understand the investment implications of environmental, social and governance (ESG) factors and to support its international network of investor signatories in incorporating these factors into their investment and ownership decisions.
