Our technologies enable our customers to provide consumers with more powerful technologies, while lowering energy demands. We align our strategies across the industry, including with customers and industry standards, to focus on key areas including reducing greenhouse gases and water consumption, improving our recycling and reuse of raw materials, and focusing on responsibly designed and operated facilities.
Our enabling technology is not the only approach we take to improve environmental performance. Our ZERO HARM! philosophy drives us to continually improve our environmental performance both in our own operations and in our products, so that our customers realize a reduced environmental footprint.
Our environmental policy is a core element of our overall corporate responsibility Policy. This policy establishes our commitment to reduce our environmental impact by continuously improving our management systems and setting objectives. The policy is not limited to any one aspect of environmental protection, and we will continuously evaluate our performance in areas applicable to our operations and products.
In 2016, we initiated a five-year target cycle for reducing our environmental footprint in key areas that are applicable to our operations and aligned with industry standards, including the Sustainability Accounting Standards Board (SASB) accounting standards for the semiconductor industry. Our environmental targets remain unchanged for 2016-2020 and are:
These targets are aligned with key initiatives across our operations, and leverage our environmental management system which is certified to the ISO 14001 standard to further improve visibility across the company. Over 95% of our realized greenhouse gas emissions are a direct result of scope 2 purchased electricity. We strive to find ways to reduce our electrical consumption where we use it most, at our engineering, and research and development. For example, we commissioned an energy audit in partnership with a local utility at one of our engineering sites, and are exploring the opportunities identified in future objective setting for the targets, objectives and actions taken to support SDG 13: Climate Action.
Further to the applicable targets, we evaluate our overall environment aspects and impacts, including changes in regulatory aspects, on an annual basis to identify any change in operations or impacts that require inclusion. In 2017, no material changes to our current operations occurred that alters the way we interface with the ecosystem or manage our on-site surface water. We approach new projects with a impact assessment, and strive to minimize identified potential impacts, such as through erosion protection, surface water containment, abatement technologies, and water resource management.
