Data Collection The public may access data on greenhouse gas emissions on the United Nations Framework Convention on Climate Change’s (UNFCCC) webpage. The UNFCCC data interface provides a huge variety of GHG data, where data are shown for individual parties or groups of parties, for various greenhouse gases or for their total, and in varying
Quantitative
Carbon Dioxide and Black Carbon Absorption
Data Collection The Carbon Dioxide Analysis Center (CDIAC) and the Global Carbon Project are the primary data sources for carbon dioxide emissions statistics. The UN Statistical Office, which aggregates data from official national statistical publications and yearly questionnaires, provides a source for more current carbon dioxide emission data. Examples Environmental Protection Agency Research on Vehicle
PEMS Exhaust Emission Tests
Data Collection Data sources on PEMS exhaust emission are obtained using the PEMS technology tool to measure the total emissions from vehicles. The measurements are tested with respect to the nitrogen oxide (NOx), carbon dioxide, and particle number. The precise measurement data is collated after the process of collection using this tool. Examples Study on
Change in Vehicle Emissions
Data Collection Data on changes in vehicle emissions can be collated using the Motor Vehicle Emission Simulator (MOVES). Additionally, official documentation may be used to offer data on vehicle emissions (brochures or specifications). Vehicle emission data is also easily accessible owing to the European Automobile Manufacturers Association (ACEA). Examples A decade of on-road emissions measurements
Change in Measured Ambient Air Quality
Data Collection Data on ambient air quality can be collated from the Air Quality System (AQS), which is a national repository. The data is collected by the EPA, state, local, and tribal air pollution control agencies. Additionally, the public may access air quality data gathered from outdoor monitors via the EPA’s Air Data website. Examples
Number of Electrified Fleets
Data Collection There are a few different ways to track the number of electrified fleets around the world. The International Energy Agency (IEA) holds one of the most comprehensive data sets by maintaining a database of electric vehicle fleets. Other useful sources of information include national government agencies and industry associations. One way to estimate
Driving Cycles Tracking
Data Collection Driving cycle data can be collected from the National Renewable Energy Laboratory (NREL) NREL database. Data from the NREL is provided for data surveys and research that incorporates second-by-second data collecting from automobiles equipped with global positioning systems (GPS). Examples National Renewable Energy Laboratory (NREL) The research on driving cycle tracking was conducted
Number of People with Increased Access to Healthy Destinations
Data Collection The National Center for Health Statistics provides data on the number of individuals with access to healthcare. The data are collected through surveys, publications, or questionnaires. Examples Public Transport Authority (PTA) The Public Transport Authority (PTA) is the organization responsible for measuring the number of people with easy access to public transport to
Number of people with increased access to health promoting opportunities
Data Collection Healthy People 2030 uses more than 80 data systems to track the progress towards ensuring individuals have access to health opportunities. The National Vital Statistics System and other national censuses of events, as well as surveys using samples drawn randomly from the whole country, are often used to gather data. Examples The Public
ADA Non-Compliant Areas
Data Collection The ADA National Network is a great resource for data and information on the ADA. The ADA National Network collects data through various means, including surveys, focus groups, and interviews with people with disabilities, their families, and service providers. This data is then used to develop resources and services that support the independence
