London Energy and Greenhouse Gas Inventory 2008 showing greenhouse gas emissions and energy consumption. LEGGI 2008 is a database of geographically referenced datasets of energy consumption within the Greater London area and estimates of the quantity of resulting greenhouse gases (GHG) – carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6) – emitted into the air. _Technical Information_ Due to the size of the LEGGI database this dataset has been zipped and needs to be downloaded in two parts: 1. [MS Access Database](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/gla-leggi-2008-database.zip) (63mb zipped) 2. [Supporting Folders and Files](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/gla-leggi-2008-folders.zip) (154mb zipped) To use the LEGGI database please download both files to a local drive and extract the contents to the same folder. Double-click the LEGGI_2008.mdb file to start the system. For further details please consult the User Guide and Emission Estimation Methodology Guide which can be found in the Documentation folder after the files have been extracted.

The LAEI 2008 has been replaced by the LAEI 2010 available from 10 July 2013. Estimates of eight key and six subsidiary pollutants are included for the base year 2008 and projected forward to 2011 and 2015. The LAEI area covers the 32 London Boroughs and the City of London and up to the M25 motorway. Detailed [concentration modelling maps](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/laei-2008-concentration-maps) from the LAEI 2008 can also be downloaded from the Datastore. Technical Information: Due to the size of the LAEI database this dataset has been zipped and needs to be downloaded in two parts. The front-end MS Access database is available in two formats - 2000 and 2003. Please choose the appropriate one depending on which version of MS Office (Access, Excel and Word) you have installed on your machine. 1. [MS Access 2003 Format Database](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/datafiles/environment/laei-2008-database.zip) (226mb zipped) 2. [MS Access 2000 Format Database ](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/datafiles/environment/laei-2008-database-v2000.zip)(219mb zipped) All users will also need to download the supporting files and folders in order for either databases to function properly. [Supporting Folders and Files](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/datafiles/environment/laei-2008-folders.zip) (98mb zipped) To use the LAEI please download either of the front-end databases and the supporting files to a local drive and extract the contents to a new folder using the "use folder names" option. The contents of the folder to which you extracted the files should look like [the example image](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/datastorefiles/images/laei-2008-extract-folder.png). Double-click the LAEI_2008.mdb file to start the system. Due to the size of this database we recommend working on a local drive rather than over a network. For further details please consult the User Guide and Emission Estimation Methodology Guide which can be found in the Documentation folder after the files have been extracted. In particular please note the final section regarding software object libraries which may be important if you experience any compatibility problems with different version of Access and Excel.

The [Code of Recommended Practice for Local Authorities on Data Transparency](http://www.communities.gov.uk/publications/localgovernment/transparencycode), issued by the Department for Communities & Local Government in September 2011, set out a number of principles for local authorities which were intended to underpin best practice in the creation of greater transparency through the publication of public data. One of the key requirements was the publication of senior employee salaries above £58,200 together with names, job descriptions, responsibilities and budgets. [View senior staff salaries for the GLA, together with links to job descriptions](http://www.london.gov.uk/mayor-assembly/gla/spending-money-wisely/salaries-and-expenses/gla-senior-staff-salaries). A [departmental organisation chart (PDF)](http://www.london.gov.uk/sites/default/files/GLA%20org%20chart%20July%202012_0.pdf) is also available. It should be noted that the Code provided for individuals to be given the option to refuse consent for their name to be published and, where the name is given as 'withheld', this is because the individual concerned has expressly refused consent for their name to be included. The [CSV file of the senior staff data](http://www.london.gov.uk/sites/default/files/GLA%20employee%20salaries%2019%20July%202012.csv) is a basic format spreadsheet which permits analysis of the data.

London’s Environment Revealed is a joint report on the State of the Environment in London, produced by the Greater London Authority, Environment Agency, Natural England and the Forestry Commission. The report looks at the state of London’s environment today, highlights the improvements that have been made, and the challenges the city faces. The report also features many projects and schemes at a local level that have improved the environment in London in recent years. The report uses a series of indicators to illustrate the changes in the state of the environment within eight themes: Climate change, Flood risk, Water quality, Water resources, Waste, Air quality, noise and transport, Biodiversity, and Landscape and green infrastructure. The report was first published in 2011. It has been refreshed in 2013 through an update of the indicators.

There are 187 Air Quality Focus Areas in the Capital. These are locations that not only exceed the EU annual mean limit value for NO2 but are also locations with high human exposure. The Focus Areas were defined to address concerns raised by boroughs within the LAQM review process and forecasted air pollution trends. This is not an exhaustive list of London’s hotspot locations, but where the GLA believe the problem to be most acute.
