Our environmental program helps NXP conserve vital energy resources and increase our efficiency. We monitor and measure the environmental impacts using a sustainability management system which measures and tracks the energy consumption of our manufacturing sites.
We use electricity and natural gas, and a small amount of diesel to run our emergency generators.
Our electricity-conservation projects address both consumption reductions and opportunities to purchase electricity from renewable energy sources.
Semiconductor manufacturing is an electricity-intensive process. As a result, our wafer-fabrication sites represent the majority of our electricity use. Non-manufacturing electricity is only 3% of NXP's total consumption.
Our manufacturing facilities require a significant amount of electricity, therefore our strategic focus is on conservation initiatives and improving process efficiencies.
Our manufacturing sites continually optimize processes and upgrade equipment to reduce electricity consumption.
Electricity consumption at our offices and R&D centers is 3% of our total consumption. In 2021, our absolute electricity consumption increased by 2% compared to 2020 as a result of team members returning to the office in sites where COVID-19 conditions improved.
In addition to electricity, we consume minimal energy from sources such as natural gas, diesel and other fossil fuels.
