Epson and the Environment

Eco Community

Introduction of corporate citizenship programs that leverage Epson's technologies.


Loggerhead Sea Turtle Protection Project

Hatchlings headed for the ocean

Epson has been working with Kamogawa Sea World and the Japanese government since June 2010 in a project to help protect and preserve endangered loggerhead sea turtles. The project is part of the company's ongoing desire to preserve biodiversity and to test its sensing technology in the field.

Epson Making Valuable Contributions to University Research on Loggerhead Turtles

Shohei Kobayashi
Tokyo University of Agriculture and Technology
Veterinary Physiology Laboratory

Our laboratory is conducting collaborative research with Kamogawa Sea World to establish non-invasive methods to identify the gender of endangered loggerhead sea turtle hatchlings. The gender of sea turtles is determined by the temperature to which the egg is exposed during the incubation period, and Epson has provided a wireless temperature data-logger that enables this to be established. Our results suggests a correlation between temperature and sex steroid hormone concentration. We hope that Epson will continue to support this collaborative research to clarify the impact of climate change on sea turtles and contribute to their conservation.

Supporting PFC Gas Reductionswith the Epson Method

Greenmethod is a registered trademark relating to environmental
technologies including the Epson method.

Perfluorocarbons (PFC ) were considered to be among the most difficult to measure of the non-CO2 greenhouse gases until 2000, when Epson developed the "Epson Method." The Epson Method, a simple and accurate way to calculate PFC emissions based on FT-IR (Fourier Transform Infrared Spectroscopy), made it possible to sharply reduce the level of PFC emissions. The Epson Method is patented. However, Epson grants a free license to use the technology under certain conditions, in the hopes of helping other companies reduce PFC gas emissions.


Incentives for Eco-Inventions

From 1998, Epson has been providing incentives for eco-inventions; that is, inventions that have a marked effect on the mitigation of environmental impacts. The aim of the incentives program is to contribute to society by becoming the industry leader in the development of technology to reduce environmental impacts.
