North America Estimated Annual Truck CO2 Emissions 2035

Overview This layer shows the locations of more than 3,000 North American power-generating facilities using fossil fuel sources in 2005, produced through a collaborative effort between the national atlas programs of Canada, Mexico, and the United States, in partnership with the Commission for Environmental Cooperation (CEC).  Each facility includes information on its primary fuel, generating capacity, and air emissions of SO2, NOx, Hg, PM2.5, PM10, CH4, N2O, and CO2. Facilities are classified based on the primary source of fuel used to generate electricity: oil, natural gas, coal, or other fuels. This map layer was developed for the CEC's 2011 publication, North American Power Plant Air Emissions. Fossil fuels are the main energy source used for electricity generation in North America, producing almost two-thirds of the electricity consumed. The data were assembled primarily from the three North American countries' national emission inventories: Canada's National Pollutant Release Inventory (NPRI) and Greenhouse Gas Emissions Reporting Program (GHGRP); the United States' Emissions and Generation Resource Integrated Database (eGRID2007) and National Emissions Inventory (NEI); and Mexico's Inventario Nacional de Emisiones (INEM), compiled from publicly available databases and reports. A Google Earth (KMZ) map of the 3,144 power plants and their air emissions is also available. For more information. Geographic Coverage The coverage spans the entire North American continent, including power-generating facilities located in Canada, Mexico, and the United States.

Overview This map layer presents a dataset of named populated places across North America, encompassing Canada, the United States, and Mexico, suitable for use at a continental scale of 1:10,000,000. The information is derived from the national mapping and census agencies of each country: Natural Resources Canada (NRCan), the Instituto Nacional de Estadística y Geografía (INEGI), and the U.S. Geological Survey (USGS). It is a revised version of the 2004 data set, released as part of a joint venture coordinated by the Commission for Environmental Cooperation (CEC). Places, which refer to individual municipalities, are represented as points fitted to the North American Environmental Atlas roads, railroads, and hydrography layers, so that each point reflects the approximate location of a place relative to those features. The selection of populated places was based on local importance as indicated by population size, importance as a cross-border point, and occasionally other factors. All capital cities (national, provincial, territorial, or state) are included for Canada, Mexico, and the United States. The dataset supports multiple languages for attribute names, including English, Spanish, and French, facilitating accessibility across North America. It also includes standardized identifiers and classification codes for population class, capital status, country, and state or province for each place. Geographic Coverage The coverage spans North America, including the continental territories of Canada, the United States, and Mexico. Features located outside these three countries are included only to provide geographic context and carry no completeness or accuracy guarantees from the contributing agencies.

Overview This 30-meter dataset reflects land cover information for 2010 from Mexico and Canada, and 2011 for Alaska and the conterminous United States. Each country developed its own classification method to identify land cover classes and provided an input layer to produce a continental land cover map across North America. The main inputs for image classification were 30-meter Landsat data; image selection varied by country according to site-specific requirements. Canada selected most images from 2010, with a few from 2009 and 2011; the United States primarily used 2011 imagery; and Mexico used all available images from 2010. National maps were generated for Canada by the Canada Centre for Remote Sensing (CCRS); for Mexico by the National Commission for the Knowledge and Use of Biodiversity (Comisión Nacional para el Conocimiento y Uso de la Biodiversidad), National Institute of Statistics and Geography (Instituto Nacional de Estadística y Geografía), and National Forestry Commission of Mexico (Comisión Nacional Forestal); and for the United States by the United States Geological Survey. Each country used its own approach, ancillary data, and mapping methodology, and the national datasets were then combined by the Commission for Environmental Cooperation (CEC) into a seamless North American product, merging four map sections: Alaska, Canada, the conterminous United States, and Mexico. The current version (version 3) includes updated data over Canada, provided by the CCRS and the Canada Centre for Mapping and Earth Observation (CCMEO) in February 2024, along with updated 2011 land cover datasets for Alaska and the conterminous United States, provided by the USGS in February 2024. The main change in Alaska relates to the inclusion of an improved road network. No updates were performed over Mexico for this version. Land Cover Classes The raster attribute table provides 19 thematic land cover classes plus a background value, with class names in English, Spanish, and French: 1: Temperate or sub-polar needleleaf forest 2: Sub-polar taiga needleleaf forest 3: Tropical or sub-tropical broadleaf evergreen forest 4: Tropical or sub-tropical broadleaf deciduous forest 5: Temperate or sub-polar broadleaf deciduous forest 6: Mixed forest 7: Tropical or sub-tropical shrubland 8: Temperate or sub-polar shrubland 9: Tropical or sub-tropical grassland 10: Temperate or sub-polar grassland 11: Sub-polar or polar shrubland-lichen-moss 12: Sub-polar or polar grassland-lichen-moss 13: Sub-polar or polar barren-lichen-moss 14: Wetland 15: Cropland 16: Barren lands 17: Urban and built-up 18: Water 19: Snow and ice Geographic Coverage The service covers Canada, the United States, and Mexico, including Alaska.

Overview This dataset shows North American land cover for 2005 at a spatial resolution of 250 meters, based on Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery. It provides a harmonized view of the physical cover of Earth's surface across the continent, classified into nineteen Level II land cover classes defined using the Land Cover Classification System (LCCS) standard developed by the Food and Agriculture Organization (FAO) of the United Nations. The dataset was produced as part of the North American Land Change Monitoring System (NALCMS), a trilateral effort between Natural Resources Canada, the United States Geological Survey, and three Mexican organizations: the National Institute of Statistics and Geography (Instituto Nacional de Estadística y Geografía), the National Commission for the Knowledge and Use of Biodiversity (Comisión Nacional para el Conocimiento y Uso de la Biodiversidad), and the National Forestry Commission of Mexico (Comisión Nacional Forestal). The collaboration is facilitated by the Commission for Environmental Cooperation (CEC), an international organization created by the governments of Canada, Mexico, and the United States under the North American Agreement on Environmental Cooperation to promote environmental collaboration between the three countries. Land Cover Classes The raster attribute table provides 19 thematic land cover classes: 1: Temperate or sub-polar needleleaf forest 2: Sub-polar taiga needleleaf forest 3: Tropical or sub-tropical broadleaf evergreen forest 4: Tropical or sub-tropical broadleaf deciduous forest 5: Temperate or sub-polar broadleaf deciduous forest 6: Mixed forest 7: Tropical or sub-tropical shrubland 8: Temperate or sub-polar shrubland 9: Tropical or sub-tropical grassland 10: Temperate or sub-polar grassland 11: Sub-polar or polar shrubland-lichen-moss 12: Sub-polar or polar grassland-lichen-moss 13: Sub-polar or polar barren-lichen-moss 14: Wetland 15: Cropland 16: Barren land 17: Urban and built-up 18: Water 19: Snow and ice Geographic Coverage This dataset covers Canada, Alaska, the conterminous United States, and Mexico.

Overview This layer, prepared by the Commission for Environmental Cooperation (CEC), represents the month of May within a dataset of 12 raster files (one for each month) representing total precipitation values across North America for the 1981–2010 climatological reference period, in millimeters. The dataset is derived from a kilometer-scale climate product generated using the CHELSA downscaling model and represents long-term climatological means. The North American monthly precipitation layers were derived from the CHELSA Climatologies v2.1 dataset, which is based on statistically downscaled temperature and precipitation data at a spatial resolution of 30 arc-seconds (~1 km). CHELSA (Climatologies at High Resolution for the Earth's Land Surface Areas) applies a statistical downscaling approach to atmospheric precipitation fields to produce high-resolution climate surfaces. Additional technical details on the downscaling methodology and derived climate predictors are provided in: Karger, D. N., Conrad, O., Böhner, J., Kawohl, T., Kreft, H., Soria-Auza, R.
