This is a brief user's guide to the GHG Search. Select a variety of different search options and output options detailed below.

Select more than one search option at a time to speed up the search and make the retrieval more focused. Only those facilities matching all specified criteria will be retrieved.

Facility Identification Search Option

Facility Name

Enter the complete or partial facility name to retrieve all facilities with that name. Select the "Containing" option when entering a partial name for a better retrieval the first time you access the data.

GHG Facility ID

Enter the complete or partial facility identification (ID) number provided by the GHG database. The ID cannot be more than 15 characters.

Corporate Parent Name

Enter the complete or partial corporate parent name to retrieve all facilities with that corporate parent name. Select the "Containing" option when entering a partial name for a better retrieval the first time you access the data.

Geography Search Option

Select from the following geographical search options: ZIP Code, Address, City, County, and State.

ZIP Code

The entry can be one or more digits. It allows you to enter the zip plus-4 extension as well.

Address

Enter a complete or partial street address.

City

Enter a complete or partial city name. Entering the two-character state postal abbreviation will help to narrow the search.

County

Enter a complete or partial county name and a two-character state postal abbreviation. Entering the two-character state postal abbreviation will help to narrow the search

State

Enter a two-character state postal abbreviation. A list of the postal abbreviations and the state names is provided below:

AK = Alaska AL = Alabama AR = Arkansas
AS = American Samoa AZ = Arizona CA = California
CN = Canada CO = Colorado CT = Connecticut
DC = District of Columbia DE = Delaware FL = Florida
FM = Federated States of Micronesia GA = Georgia GU = Guam
HI = Hawaii IA = Iowa ID = Idaho
IL = Illinois IN = Indiana KS = Kansas
KY = Kentucky LA = Louisiana MA = Massachusetts
MD = Maryland ME = Maine MH = Marshall Island
MI = Michigan MN = Minnesota MO = Missouri
MP = Northern Mariana Islands MS = Mississippi MT = Montana
NC = North Carolina ND = North Dakota NE = Nebraska
NH = New Hampshire NJ = New Jersey NM = New Mexico
NV = Nevada NY = New York OH = Ohio
OK = Oklahoma OR = Oregon PA = Pennsylvania
PR = Puerto Rico PW = Palau, Republic of RI = Rhode Island
SC = South Carolina SD = South Dakota TN = Tennessee
TX = Texas UT = Utah VA = Virginia
VI = Virgin Islands VT = Vermont WA = Washington
WI = Wisconsin WV = West Virginia WY = Wyoming

Note: We strongly recommend that you enter a small geographical area to begin the search since Envirofacts contains a large number of facilities.

Facility Industrial Classification Search Option

NAICS Code Description

The North American Industry Classification System (NAICS) Code(s) that best describe the business activities conducted at a facility or establishment. NAICS codes are 6 digit numbers used by the Bureau of Census as part of a system to categorize and track the types of business activities conducted in the United States.

The individual digits within the NAICS code indicate different levels of granularity in identifying a business. Here is an example of the granularity the individual digits provide:

No. Example
Digits NAICS Definition / Granularity
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Two 31xxxx Manufacturing
Three 311xxx Food Manufacturing
Four 3115xx Food Manufacturing, Diary Products
Five 31151x Food Manufacturing, Diary Products, (Not Frozen)
Six 311511 Food Manufacturing, Diary Products, (Not Frozen), Fluid Milk

A facility may be comprised of one or more establishments. An establishment is an economic unit, generally at a single physical location, where business is conducted or where services or industrial operations are performed. Each establishment may have a unique NAICS code.

Reporting Year

Data from 2010 and 2011 is available for selection.

Greenhouse Gas

By default all gases are searched. To narrow your search, select a specific gas(es). The available gases are:

Carbon Dioxide (CO2) is a naturally occurring gas and is a by-product of burning fossil fuels and biomass, as well as land-use changes and other industrial processes. It is the principal anthropogenic greenhouse gas that affects the Earth's radiative balance. It is the reference gas against which other greenhouse gases are measured and therefore has a Global Warming Potential of 1.

Nitrous Oxide (N2O) is a powerful greenhouse gas with a global warming potential of 310 times that of carbon dioxide (CO2). Major sources of nitrous oxide include soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning.

Methane (CH4) is a hydrocarbon and a greenhouse gas with a global warming potential of 21. Methane is produced through anaerobic (without oxygen) decomposition of waste in landfills, animal digestion, decomposition of animal wastes, production and distribution of natural gas and petroleum, coal production, and incomplete fossil fuel combustion.

Perfluorocarbons (PFCs) are a type of greenhouse gas. PFCs are a group of man-made chemicals composed of carbon and fluorine only. These chemicals were introduced as alternatives, along with hydrofluorocarbons, to the ozone depleting substances. PFCs are emitted as by-products of industrial processes and are also used in manufacturing. PFCs do not harm the stratospheric ozone layer, but they are powerful greenhouse gases.

Hydrofluorocarbons (HFCs) are a type of greenhouse gas. Hydrofluorocarbons are compounds that contain only hydrogen, fluorine, and carbon atoms. They were introduced as alternatives to ozone depleting substances in serving many industrial, commercial, and personal needs. HFCs are emitted as by-products of industrial processes and are also used in manufacturing. They do not significantly deplete the stratospheric ozone layer, but they are powerful greenhouse gases.

Emission Range

Click and drag the sliders to set a minimum and/or maximum value for annual facility emissions. Alternatively, you may type minimum and maximum values manually in the provided text boxes.

Emitter / Supplier

Emitters are facilities that combust fuels or otherwise put GHGs into the atmosphere directly from their facility. An example of this is a power plant that burns coal or natural gas and emits carbon dioxide directly into the atmosphere.

Suppliers are those entities that supply products into the economy which if combusted, released or oxidized emit greenhouse gases into the atmosphere. These fuels and industrial gases are not emitted from the supplier facility but instead distributed throughout the country and used. An example of this is gasoline, which is sold in the U.S. and primarily burned in cars throughout the country. The majority of GHG emissions associated with the transportation, residential and commercial sectors are accounted for by these suppliers.

Sector/Subsector

To limit the search to a specific sector or subsector, click on the checkbox(s) next to the sector(s) or subsector(s) of interest.

Subpart

To limit the search to a specific subpart, click on the checkbox(s) next to the subpart(s) of interest.

You may search for a sector/subsector or a subpart, but not both simultaneously.
