# Baton Rouge Refinery

ExxonMobil's Baton Rouge Refinery in Baton Rouge, Louisiana is the sixth-largest oil refinery in the United States and seventeenth-largest in the world, with an input capacity of 540,000 barrels (86,000 m$^3$) per day as of January 1, 2020. The refinery is the site of the first commercial fluid catalytic cracking plant that began processing at the refinery on May 25, 1942.
Standard Oil first erected the refinery in 1909. Today's facility is part of a complex made of nine individual plants across the region. The main plant is located on the east bank of the Mississippi River. There are about 6,300 workers spread across these sites, including 4,000 direct employees (the rest are contractors).
In 2013 Genesis Energy LP announced an investment of $125 million to improve ExxonMobil's existing assets in the Baton Rouge area. The investment includes plans to build an 18-mile (29 km), 20-inch (51 cm) diameter crude oil pipeline that connects Genesis Energy's Port Hudson terminal, to ExxonMobil's Baton Rouge refinery.

## Greenhouse gas emissions history

As a major emitting facility, The ExxonMobil Baton Rouge Refinery and Petrochemical Site must report its complete greenhouse gas emissions to the EPA every year subject to the EPA's Greenhouse Gas Reporting Program. The Baton Rouge reports as four separate facilities but with the integrated refinery and olefins unit being the largest and accounting for >95% of emissions. The reporting codes are below:
| Facility Name | EPA Facility ID | FRS ID |
| EXXONMOBIL BATON ROUGE REFINERY AND CHEMICAL PLANT | 1007643 | 110043804185 |
| EXXONMOBIL CHEMICAL CO - BATON ROUGE POLYOLEFINS PLANT | 1006801 | 110000450011 |
| EXXONMOBIL CHEMICAL CO - BATON ROUGE PLASTICS PLANT | 1003484 | 110070834663 |
| Exxon Mobil Corporation-Baton Rouge Resin Finishing Plant | 1014575 | 110071165420 |
The greenhouse gas emissions by year are reported below:
| Year | Total Reported Direct Emissions | CO2 Emissions Non-Biogenic | Methane Emissions | Nitrous Oxide Emissions |
| | metric ton | metric ton | metric ton | metric ton |
| 2023 | 5,914,862 | 5,883,262 | 17,160 | 14,440 |
The Baton Rouge Refinery is one of the ten largest emitting refineries in the United States according to Reuters. However, it is also a top ten refinery in size and complexity and is deeply integrated with its petrochemical business.
