About the EICC
Founded in 2004 by a group of leading electronics companies, the EICC is a nonprofit coalition of electronics companies committed to supporting the rights and wellbeing of workers and communities worldwide affected by the global electronics supply chain. EICC members commit and are held accountable to a common Code of Conduct and utilize a range of EICC training and assessment tools to support continuous improvement in the social, environmental and ethical responsibility of their supply chains.

TCO Development
TCO Development helps organizations integrate sustainable IT as part of an overall sustainability strategy. We are the organization behind the TCO Certified sustainability certification for IT products, offering businesses and organizations a way to reduce their environmental impact and improve their work environments and efficiency.
For over 20 years, our international dialog with multiple stakeholders; users, buyers, industry, independent experts and NGOs has allowed us to help drive more sustainable development in IT throughout the life cycle phases; manufacturing, use and end of life. We work internationally and are owned by TCO, a non-profit organization based in Stockholm, Sweden.
Sustainable IT is defined by three elements: using IT as an aspect of a sustainability strategy, making the organization’s IT systems more sustainable, and including sustainability criteria when buying IT products.

An Assessment of Software Lifecycle Energy
Paper on An Assessment of Software Lifecycle Energy
Abstract—Software energy assessment is important for
reducing environmental impact of modern information
technologies (IT). While software does not consume energy, for
any computing hardware the energy cost of processing strongly
depends on control defined by software. This paper analyzes the
total energy consumption associated with software production,
delivery and use and assesses their contribution to green-house
gas emissions. The results reveal that the energy consumed at the
production stage dominates the total lifecycle energy as software
size grows. However, if software is largely used, most of the
lifecycle energy is consumed at the use stage. For software as big
as Linux 3.2 kernel, the total lifecycle energy exceeds 51 Giga
Watt-hours i.e. equivalent of 31kilotons of CO2 emission.
Reducing this environmental impact requires energy–conscious
software development and management. This paper is not
intended as a comprehensive analysis rather as a starting point
for research toward green software development.
