Reducing Emissions (Including Greenhouse Gases)

Reducing Emissions

Including Greenhouse Gases

Reducing our Carbon Footprint

Greenhouse gases in the atmosphere act like a blanket or glass roof around the earth, trapping in heat that would otherwise escape to space. This is commonly referred to as the “greenhouse effect.” Carbon dioxide (CO2) is the most significant greenhouse gas released by human activities and is emitted mostly from the burning of fossil fuels like coal, oil, and natural gas. Other greenhouse gases include methane and nitrous oxide.

Semiconductor manufacturing is not considered a major contributor to global warming, but our operations do directly and indirectly emit greenhouse gases. We measure, manage and report our Scope 1, 2 and some Scope 3 emissions. Emissions are reported in terms of tons of CO2 equivalents.

Goal

NXP’s 2020 goal is to reduce our normalized carbon footprint by 30% from a baseline year of 2010. Our production normalizer is based on the square meter of silicon wafers produced.

Strategy

NXP aims to reduce our carbon footprint, through utility consumption conservation, process optimization, greenhouse gas replacement, point of use abatement projects, optimizing product transport, and business travel. As part of this effort, our combined sites had multiple reduction projects such as:

  • Using more efficient lighting technologies and schedules
  • Optimizing building operations and product testing processes
  • Powering down equipment when not used
  • Using substitute chemicals to reduce heat transfer fluid emissions from our equipment
  • Installing new abatement equipment to reduce Perfluorinated Compounds (PFC) emissions

Performance

Between 2010 and 2018, our normalized total emissions for Scope 1, 2 and 3, (direct and indirect) decreased by approximately 21%, all resulting from many projects over the past 8 years.

NXP’s reduction target is an “absolute” emissions reduction, meaning a commitment to reduce regardless of the expended growth of production. Our Scope 1 Emissions include fossil fuel to heat buildings, the use of PFCs and N2O in our manufacturing of integrated circuits, and the use of HTFs, such as HydroFluoroCarbons (HFCs) and Per fluoro Ethers for device testing and cooling purposes. Our Scope 2 emissions include electricity purchased. Our Scope 3 emissions include business travel and product transport.
