Environmental reporting

EnQuest is a responsible operator, focused on reducing absolute Scope 1 and 2 emissions across our operations

Our Environmental Management System (EMS) ensures our activities are conducted in such a way that we manage and mitigate our impact on the environment. The system meets the requirements of OSPAR recommendation 2003/5 and is aligned with the requirements of the International Organisation for Standardisation’s environmental management system standard – ISO 14001. The Enquest EMS is independently verified every two years.

In the UK, we publish our annual Environmental Statement in line with the regulatory requirement under the OSPAR recommendation 2003/5. These statements are an open and transparent representation of our environmental performance across our offshore operations.
Related public statements are available via the website of the Department for Business, Energy and Industrial Strategy (BEIS).

The environmental requirement in Malaysia is addressed as part of the EnQuest Malaysia Management System and in line with the ISO 14001. Greenhouse Gases (GHG) reporting was published on annual basis to PETRONAS as part of mandatory KPI submission in line with PETRONAS Procedures and Guidelines for Upstream Activities (PPGUA) requirement.

We are committed to further improving EnQuest's environmental performance by minimising flaring and the quantity of produced oil in water discharged to ensure adherence to regulatory requirements.

In addition, the decisions to cease production at our Heather, Thistle and Alma/Galia fields, along with other emissions reduction initiatives, have reduced our Group Scope 1 and 2 emissions by 26% since 2018.

Looking ahead, we are targeting a further 10% reduction in emissions from exisitng operations, over the period 2021 to 2023, through the implementation of various economic emissions avoidance initiatives.

Greenhouse gas (‘GHG’) emissions

EnQuest has reported on all of the emission sources within its operational control required under the Companies Act 2006 (Strategic Report and Directors’ Reports) Regulations 2013. These sources fall within the EnQuest consolidated financial statements. EnQuest has used the principles of the GHG Protocol Corporate Accounting and Reporting Standard (revised edition), ISO 14064-1 and data gathered to fulfil the requirements under the ‘Environmental Reporting Guidelines: Including Mandatory Greenhouse Gas Emissions Reporting Guidance’ June 2013. The Mandatory Carbon Reporting (‘MCR’) report includes assets which are in the operational control of EnQuest.

1 When it is considered that the portfolio of assets under a Company's operational control has changed significantly, the baseline, which is based on Verified Scope data, is recalculated to an appropriate comparative period for which good data is available. As such, the baseline is currently 2015 
2 tco2e = tonnes of co2 equivalent. kgco2e = kilogrammes of co2 equivalent. BOE= barrel of oil equivalent. EnQuest is required to report the aggregate gross (100%) emissions for those assets over which it has operational control. As such, the extraction intensity ratio is calculated by taking the aggregate gross (100%) reported Scope I and 2 kgCO2e from those assets divided by the aggregate gross (100%) hydrocarbon production from the same assets. The throughput ratio is calculated by taking the aggregate gross (100%) reported Scope I and 2 kgCO2e from SVT divided by the aggregate total throughput at the terminal 
3 Note on Uncertainty: The uncertainty for total emissions within the verified scope is calculated as 3%. SVT emissions in isolation are not within 5% due to the steam and electricity meters for SVT not having supportable uncertainties 
4 2020 is the first SECR reporting year requiring energy consumption reporting for EnQuest. In future years, the previous year energy consumption will also be reported for comparison purposes
