ExxonMobil continually invests in systems and technologies that improve energy efficiency and reduce carbon dioxide emissions. At our production facilities, we use energy as efficiently as possible.

Cogeneration

Cogeneration or combined heat and power (CHP) is the use of a heat engine or power station to generate electricity and useful heat at the same time. Because of the combined generation of electricity and steam at our refineries, our production facilities achieve an ultra-high-efficiency rating.

Integration

Many of our chemical plants are integrated with the refinery, which leads to significant energy savings and cost reductions.

Vehicle and fuel technology

ExxonMobil works actively on the development of new engine technologies, which enable cars to drive more economically.
