Atmospheric Emissions – Reporting

Key Legislation: The UK is party to a number of international conventions and EU Directives that require the provision of atmospheric emission inventories, in particular:

  • EC Decision 93/389/EEC for a monitoring mechanism of Community CO2 and other greenhouse gas emissions – European Pollutant Emissions Register (EPER).
  • EC Directive 2008/1/EC concerning integrated pollution prevention and control, which consolidates EC Directive 96/61 and its amendments.
  • EC Directive 2003/87/EC establishing a scheme for greenhouse gas emission allowance trading within the Community and amending Council Directive 96/61/EC (EU Emissions Trading Scheme – EU ETS).
  • EC Directive 2016/2284 on the reduction of national emissions of certain atmospheric pollutants, implemented by the National Emission Ceilings Regulations SI 2018/129 in England, Wales, Scotland and Northern Ireland.
  • EC Regulation 166/2006 concerning the establishment of a European Pollutant Release and Transfer Register (E-PRTR).
  • EU Regulation 842/2018 on binding annual greenhouse gas emission reductions by Member States from 2021 to 2030 contributing to climate action to meet commitments under the Paris Agreement and amending Regulation (EU) 525/2013.
  • Geneva Convention on Long-Range Transboundary Air Pollution 1979 and its protocols.
  • UN-ECE Protocol on Pollutant Release and Transfer Registers (PRTR).
  • United Nations Framework Convention on Climate Change 1992 (Rio Convention) and its protocols (e.g. Kyoto Protocol).

Supporting Legislation:
European Pollutant Release and Transfer Register

Article 15(3) of the IPPC Directive requires the publication of an EC inventory of principal emissions and their sources. This provides information to the public, and helps authorities to assess the effectiveness of IPPC and identify priority areas.

From 2007 onwards this reporting system has been the European Pollutant Release and Transfer Register (E-PRTR) under Council Regulation 166/2006. As a signatory state to the UNECE PRTR Protocol, the UK is also required to establish a national PRTR (UK-PRTR).

BEIS collects emissions data for input to the UK-PRTR and the E-EPTR through the EEMS Reporting System (see below).

BEIS already collects emissions data for offshore oil and gas activities via EEMS. As such, it is not a new E-PRTR sector, but the reporting requirements of EEMS in terms of substances and thresholds will need to be extended to meet those of the E-PRTR Regulation. In this context, Oil & Gas UK commissioned an analysis (which has now been completed) to identify emissions of all E-PRTR pollutants that are relevant from an offshore perspective. BEIS and Oil & Gas UK will evaluate the results of this analysis to agree a way forward regarding compliance by the offshore industry with E-PRTR reporting requirements.

In addition, BEIS will continue to work closely with Oil & Gas UK on the intention to use the provisions of existing offshore regulations (e.g. the Offshore IPPC Regulations) for the purposes of enforcing the E-PRTR reporting requirements and imposing penalties for non-compliance.

BEIS will need to review and adjust accordingly the annual fees charged to operators for the maintenance of the EEMS database, in order to reflect new developments relating to E-PRTR/UK-PRTR reporting.

EEMS Reporting:

The Environmental Emissions Monitoring System (EEMS) was designed to enable the analysis of offshore (including terminals) oil industry environmental data, providing the offshore industry with an independent source of totalled environmental data on which to base its discussions with the government or within the industry itself. The dataset is accessible to both Government (BEIS) and industry (Oil & Gas UK) and acts as the primary data storage and reporting resource for both the UK Government and the offshore industry.

EEMS provides the vehicle for offshore oil and gas industry emissions to be incorporated into annual UK inventories of atmospheric emissions that are required under a number of international conventions and EU instruments (see above).

The EEMS reporting system now also includes a number of statutory reporting requirements, in particular reporting requirements under the Offshore Combustions Installations (Prevention and Control of Pollution) Regulations 2001 (as amended) (see Power Generation).

EU Emissions Trading Scheme: In addition to atmospheric reporting through the EEMS system there are also other statutory reporting requirements under the EU Emissions Trading Scheme (see EU ETS for further details).
Energy Savings Opportunity Scheme The Energy Savings Opportunity Scheme (Amendment) Regulations 2014

  • These Regulations amend Schedules 1, 2 and 4 to the Energy Savings Opportunity Scheme Regulations 2014 to correct drafting errors.
    Section 2.4 has been updated to provide further clarification on vessels supporting the offshore industry;
  • Section 3.3.4 has been updated to introduce an alternative joint venture agreement for compliance of offshore assets;
  • Section 5.3.2. now includes further clarification on independence of lead assessors;
  • Section 7.1 includes amendments to sign-off requirements;
  • Additional compliance checks have been added to Section 9.1;
  • New Notification Questions have been added to Section 11.
Consent Needed: A number of consents may be needed for atmospheric emissions, in particular EU ETS, Flaring, Venting and Power Generation. See specific topics for consent requirements. The following applies only to reporting requirements under EEMS.
How to Apply: N/A
Who to Apply to: N/A
When to Apply: N/A
Performance Standards:


Measurements and Calculations: The methodology involves the application of emission factors to process information which includes:

  • Fuel consumption in process turbines, heaters and engines
  • Flaring and venting volumes
  • Tanker loading volumes
  • Number and type of components (fugitive emission est.)

The EEMS spreadsheets use generic emission factors as developed by Oil and Gas UK. However, platform or vessel specific factors should be used in place of the default factors as per specific PPL and EU ETS consent requirements.

What to Report: An annual report of all atmospheric emissions from the following must be submitted:

  • Production of oil and gas from offshore reservoirs, including loading operations
  • Onshore terminals engaged in processing/storing/loading
  • Exploration, appraisal and development drilling rigs

Emissions from support vessels, tankers on-route, helicopters and seismic vessels are not included, because these emissions are input by other sectors into the UK National Inventory.

How to Report: Atmospheric emissions data should be reported by completing the EEMSATMO form which can be downloaded from the EEMS Website. The EEMS reporting form includes a number of calculations to assist in emission reporting. Additional guidance on how to complete the form and factors used in the calculations can be obtained from the Guidance Notes, also on the EEMS website.
Who to Report to: Completed reports are to be submitted electronically to the EEMS website.
When to Report: Completed EEMS forms must be submitted by 7 February each year. For wells, the completed EEMS form must be submitted one month after completion of drilling.
