Carbon Offsets

In line with our company philosophy, IERS, LLC believes in reducing the environmental impact of not only our clients, but also our own operations. We calculated our carbon footprint in 2013 and verified the results through a third party. Since 2014, IERS has achieved carbon neutrality by purchasing offsets from TerraPass, using the 2013 results as a baseline. We continue to takes steps to reduce our environmental footprint wherever possible, with a current goal of reducing size-adjusted greenhouse gas emissions by 20% by 2020.
