Environmental Responsibility

Committed to creating a healthy and sustainable environment

In January 2008, L.E.K. became the first global management consulting firm to become carbon neutral across its global operations. L.E.K.'s carbon management strategy follows the framework of "reduce, replace, then offset" as defined by the Carbon Trust, a British government organization that helps businesses reduce their carbon emissions.

Reducing direct carbon emissions

L.E.K.'s carbon management strategy targets a 20% reduction in emissions in the next three years. To meet this target, L.E.K. has engaged employees in various ways to drive local initiatives to reduce carbon emissions:

  • Building management: Reduce emissions from each L.E.K. office by reviewing energy suppliers, switching to low-power light bulbs, and optimizing heating and cooling cycles.
  • IT management: Encourage responsible use of personal computers and IT equipment. This includes very simple steps like turning computers off overnight and defaulting to double-sided printing.
  • Business travel: Encourage the use of greener travel modes.
  • Administration: Reduce office supply consumption through increased recycling and the use of recycled and sustainable sourced paper, as well as working with like-minded suppliers.
  • Staff initiatives: Ensure reduction initiatives are implemented by establishing staff groups to lead initiatives within each office.
  • Supplier initiatives: Reduce indirect carbon emissions by working with suppliers who support the same environmental initiatives.


To achieve carbon neutral status, L.E.K. purchases voluntary offsets through a partnership with UK-based climate and development experts ClimateCare. ClimateCare helps us select projects that meet the highest international quality standards for verification, additionality and permanence, all key factors in helping L.E.K to achieve carbon neutral status.

We support projects in developing countries, where additionality is easier to prove and where funding often goes the furthest. These projects are designed to cut carbon emission and bring a wide range of additional benefits to local communities, such as improved health standards, more jobs and increased biodiversity. One example of the many projects that L.E.K. helps to fund by offsetting with ClimateCare is the LifeStraw Carbon For Water program in Kenya.

This award winning project is a world first, delivering safe water to 4.5 million people in western Kenya. Gravity fed water filters decrease the impact on Kenya's fast depleting forests as less firewood is needed to boil water. Not only do the filters cut carbon emissions, but early studies have shown a marked decrease in the incidences of waterborne diseases such as typhoid and diarrhea. This pioneering project is the first to link carbon credits with the provision of safe water. Find out more by watching a short video clip about the project.

Measurement and reporting

To monitor its global carbon footprint, L.E.K. conducts a quarterly evaluation of carbon emissions for each of its offices. The evaluations are conducted according to a central methodology, which includes an analysis of the company’s overall energy consumption, paper usage and carbon emissions as a result of business travel.
