United States Environment Stats
Definitions
- Adjusted net national income > Constant 2000 US$: Adjusted net national income (constant 2000 US$). Adjusted net national income is GNI minus consumption of fixed capital and natural resources depletion.
- CO2 Emissions per 1000: CO2: Total Emissions (excluding land-use) Units: thousand metric tonnes of carbon dioxide. Figures expressed per thousand population for the same year.
- Climate change > CO2 emissions from electricity and heat production, total > Million metric tons: CO2 emissions from electricity and heat production, total (million metric tons). CO2 emissions from electricity and heat production is the sum of three IEA categories of CO2 emissions: (1) Main Activity Producer Electricity and Heat which contains the sum of emissions from main activity producer electricity generation, combined heat and power generation and heat plants. Main activity producers (formerly known as public utilities) are defined as those undertakings whose primary activity is to supply the public. They may be publicly or privately owned. This corresponds to IPCC Source/Sink Category 1 A 1 a. For the CO2 emissions from fuel combustion (summary) file, emissions from own on-site use of fuel in power plants (EPOWERPLT) are also included. (2) Unallocated Autoproducers which contains the emissions from the generation of electricity and/or heat by autoproducers. Autoproducers are defined as undertakings that generate electricity and/or heat, wholly or partly for their own use as an activity which supports their primary activity. They may be privately or publicly owned. In the 1996 IPCC Guidelines, these emissions would normally be distributed between industry, transport and "other" sectors. (3) Other Energy Industries contains emissions from fuel combusted in petroleum refineries, for the manufacture of solid fuels, coal mining, oil and gas extraction and other energy-producing industries. This corresponds to the IPCC Source/Sink Categories 1 A 1 b and 1 A 1 c. According to the 1996 IPCC Guidelines, emissions from coke inputs to blast furnaces can either be counted here or in the Industrial Processes source/sink category. Within detailed sectoral calculations, certain non-energy processes can be distinguished. In the reduction of iron in a blast furnace through the combustion of coke, the primary purpose of the coke oxidation is to produce pig iron and the emissions can be considered as an industrial process. Care must be taken not to double count these emissions in both Energy and Industrial Processes. In the IEA estimations, these emissions have been included in this category.
- Coral reefs > Area > Per $ GDP: Reef areas have been rounded to the nearest 10 sq km, while for those countries with small areas of coral reefs, the terms less than 100, less than 50 and less than 10 sq km have been used. There are 80 countries and geographical locations with coral ree Per $ GDP figures expressed per $1 million of Gross Domestic Product.
- Current issues: This entry lists the most pressing and important environmental problems. The following terms and abbreviations are used throughout the entry:
-
Ecological footprint:
Ecological footprint per capita
Units: Hectares per Person -
Marine fish catch:
Total marine fish catch
Units: Metric Tons - Municipal waste generation: Kilograms of municipal waste generated per year (2000).
- Pollution perceptions > Air pollution: Air Pollution. Based on 0-50 contributions for Albania, Algeria, Argentina and 86 more countries and over 100 contributions for Australia, Canada, China and 9 more countries and 50-100 contributions for Brazil, Bulgaria, Greece and 12 more countries. The surveys were conducted by numbeo.com from January, 2011 to February, 2014. See this sample survey for the United States, respondents were asked "How satisfied are you with the quality of air in this city?". The higher the value, the more survey respondents believe it is high in their country.

- Proportion of land area under protection: Terrestrial areas protected to total surface area, percentage.
- Transport CO2 emission index: CO2 Emission Index is an estimation of CO2 consumption due to traffic time. Measurement unit is grams for the return trip. To calculate an average estimation of emission in grams for one way commute to work, divide this value with 2.
