About the data set
The U.S. Environmental Protection Agency recently approved new rules for residential wood-burning heaters. The rules, which will be phased in over five years, limit the amount of fine particle emissions that can be released in the smoke from newly manufactured products.
The included spreadsheet has two pages that provide state-by-state comparisons of fine particle emissions from residential wood burning in 2011, the latest year for which the EPA had figures. The first ranks states by their total tons of emissions in 2011. The second ranks states according to their 2011 per capita emissions. The per capita emissions are shown as pounds of emissions per resident.Download the data file: residential-wood-burning.zip
IMPORTANT notes about the data set
- This spreadsheet contains revised emission figures provided to The Associated Press on Friday, March 6, 2015, by the EPA.
- Figures provided by the EPA show "direct PM 2.5 emissions," which are fine particle emissions released directly from a source, as opposed to fine particles that form in the atmosphere as secondary reactions. The figures are from the EPA's 2011 National Emissions Inventory, which is updated every three years. Figures for 2014 are not yet available, because states have until the end of 2015 to submit data to the EPA.
- The Associated Press calculated per capita emission figures by using 2011 population data taken from the U.S. Census Bureau's "annual estimates of the resident population" for April 1, 2010, to July 1, 2014.
