User guide to WebDab

Introduction

The UNECE/EMEP emission database gives you access to national total and sector emissions, as well as activity data, for the listed areas, years, pollutant/activity classes and total/sector categories. Three different types of data sets can be accessed:

  • Officially reported emission data
  • Emissions as used in EMEP models
  • Officially reported activity data

The menu on the left side provides links to four related sections: "Officially reported emission data", "Emissions as used in EMEP models", "Officially reported activity data" and the "User guide to WebDab" (this page).

Selection boxes

On the three web pages for retrieving data ("Officially reported emission data", "Emissions as used in EMEP models" and "Officially reported activity data" you will find buttons to start the search in WebDab.

 

Clicking on such a button opens a new browser window with a search assistant, where you can select step by step the emission data you want to retrieve from WebDab. The search assistant offers selection boxes for selecting countries/areas, years, pollutants/activities, components and total/sector categories, where one or more entries in each box are selectable by clicking on the requested items. Some selection boxes allows multiple selections. Please consult your browser's manual for instructions how to perform a multiple select.

 

The search assistant guides you through the selecting process, whereas the content of the next screen always depends on the previous selections you made. So if you select e.g. a certain country and year in "Emissions as reported by Parties" and press the "Search" button, the next page will list only pollutants for selecting, which are available for the particular country and year.

 

A list box may have an "All" entry which is used to get all items in the list box. Some list boxes have other such collective entries which are used to select several items with one mouse click. Use of these entries is only intended to relieve the user from clicking on each individual item. The result seen in the browser will be the same as if each item were selected individually.

 

In "Officially reported emission data" and "Emissions as used in EMEP models" you will find a second button labeled with "Trends". Click on this button to display trend graphs and tables from 1990 to the latest available year by selecting only country and year.

Units

The unit can be switched between "g", "kg", "Mg" and "Gg". Further SOx is given as SO2 and NOx as NO2.

Officially reported emission data

Emission data officially submitted by the Parties to the CLRTAP Convention on Long Range Transboundary Air Pollutants to the EMEP project via the UNECE secretariat are available from this site. Please note that these data might be inconsistent and/or incomplete.

 

Reported gridded and LPS data is not available via WebDab, but you can download the original submission files from the section "Status of reporting"

 

Start by pushing the button "Search for officially reported emission data". A new browser window with the search assistant opens. Click you through this assistant and select one or more items from each of the list boxes described below.

 

Countries/Areas:

Contains a list of all countries reporting to the UN-ECE. Above the hyphens line (----) are four collective entries: ALL, EU15, EU25, and EU27 (i.e. EU15 plus Bulgaria, Cyprus, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Romania, Slovakia, Slovenia).

 

Years:

Years for which Parties to the Convention on LRTAP have reported emissions and projections, i.e. emission years 1980-2016 and projections for 2020, 2025, 2030 and 2050. Please note that according to the Guidelines for Estimating and Reporting Emission data, there is no obligation to report PM emissions before the year 2000. HMs and POPs reporting obligation is from 1990 onwards.

 

Reported until:

Non-gridded emissions should be reported to EMEP annually. Emission data for the actual year of reporting minus two years are requested (i.e. year 2016 emissions are reported in 2018). Projections should be reported every four years from 2015 onward.

 

If 2018 is chosen as "Latest Year of Reporting", you will retrieve the most updated emission data available from the database for the selected emission year(s) and emission category.

 

Select output format:

Two selections are possible - National Total/Sectors in either HTML or colon separated data format. Projections are marked in red color in HTML tables and a suffix "p" is added to the emission year in semi-colon separated files (i.e. 2010p).

 

Pollutants:

Pollutants in WebDab are divided into four different groups:

  • Main Pollutants: The main acidifying and eutrophying pollutants.
  • PM: Particulate matter: PM10, PM2.5, TSP and BC.
  • Heavy metals: As, Cd, Cr, Cu, Hg, Ni, Pb, Se and Zn.
  • POP: Persistent organic pollutants.

Please be aware, that the list contains only entries which are available due to the previous selection.

 

Emission Category:

There are five distinctly different emission categories linked to the five sets of UNECE Guidelines for Estimating and Reporting emission data, NFR14 / Guidelines 2014 [PDF, 194KB]NFR09 / Guidelines 2009 [PDF, 150KB], NFR02 / Guidelines 2002, NFR01 / Guidelines 2001, and SNAP / Guidelines 1997. Additionally you can select national totals for NFR14, NFR09, NFR02 or SNAP with the first entry "National Total (NFR14 / NFR09 / NFR02 / SNAP)" in the list. For national totals this four emission categories are combined, because as a result of this selection you get always the latest available data, independent from the category. E.g. if there are two national total values available for a selection, one in NFR14 and one in NFR09, and the NFR14 value has the most recent date, this value is presented as result. For users not familiar with the different EMEP/CORINAIR source categories, it is highly recommended to visit the links above before starting to request data from WebDab. Different levels of emission aggregation can be selected if available:

  • NFR Level 1: Available for NFR01, NFR02, NFR09 and NFR14 --> Sector aggregation used for gridding
  • NFR Level 2: Available for NFR01, NFR02, NFR09 and NFR14 -->Detailed sector data (reporting requirements)
  • Projections WM (projections with measures): Reported projection data should show the expected future development of polluting activity and of emissions ('current legislation projections') based on national assumptions concerning projected activity levels and considering all legal regulations or other binding measures in place.
  • Projections WaM (projections with additional measures): In addition, each Party should report on current reduction plans ('reduction projections') taking into account its obligations under the Protocols. Current legislation projections may deviate from current reduction plans in either direction depending on the state of legislation and projected future activity levels.
  • NFR01 - National total including oversea: Is "national protocol total" plus emissions in NFR 11, other sources and sinks, plus any emissions outside of the EMEP domain. For definition of EMEP domain see: http://www.emep.int/grid/grid50.pdf.
  • NFR01 - National total excluding oversea: The emissions per country regulated by their respective Protocols to the Convention of Long Range Transboundary Air Pollution.
  • NFR01 - Oversea Total: Emissions outside of the EMEP domain form countries situated mainly within the EMEP area.
  • SNAP - S1 to S11: Emissions reported in SNAP sectors

Please be aware, that the search assistant provides only emission categories which are available for the previous country, year and pollutant selection. If some categories are missing, this means that, based on the previous selection, there is no data available in this categories.

 

Sectors:

Only the sectors are listed which fits to your country, year and emission category selection. So in some cases there is no sector selection and in other cases you have to specify the sectors you want to retrieve from the database. If you choose no sector from the list, all available sectors are listed in the result.

 

In order to be able to select the correct sectors, the user is referred to the NFR14 / Guidelines 2014 [PDF, 194KB]NFR09 / Guidelines 2009 [PDF, 150KB] and NFR02 / Guidelines 2002.

 

HTML Table (columns and rows):

Here you can choose which data you want to display in the columns and rows of the HTML table, depending on your needs. You can also preselect the result unit, which can be changed directly on the result page too.

 

Information & Footnotes:

If you wish to see the comments to officially reported emission data as provided by the Parties, please flag this item. An CEIP internal report code (for example U-AT16) together with the date the emissions were received by the UNECE (for example 2016-02-15) will also appear.

 

If you choose to display HTML tables, the information will appear as footnotes at the bottom of the HTML tables. You can also hide and unhide this information directly in the result page.

 

If you prefer to see semi-colon separated files, the information will appear in the heading (separated out with hashes "#"), in front of each report the data is taken from.

 

The user should refer to the report code if having questions to a certain set of data.

Emissions as used in EMEP models

Contains national total emissions and sector data used for modeling purposes at MSC-W and MSC-E.

 

Gridded emissions as used in EMEP models are not available via WebDab, but you can download the gap-filled gridded data in 0.1° x 0.1° (long/lat) resolution directly from the CEIP website. Under "The new EMEP grid" on the CEIP website you can find more information about the spatial distributed emission data for EMEP models.

 

Emission data is based on officially reported emissions to the extent possible, but some of the officially reported data have been corrected and gaps have been filled (Important information on data consistency).

 

For modeling purposes Germany is divided into Former Federal Republic of Germany and Former German Democratic Republic, while The Russian Federation is divided into Kaliningrad, Kola/Karelia, Rest of the Russian Federation and St. Petersburg/Novgorod-Pskov.
