Climate change

Developing a position on climate change

We are however working towards a greater understanding of our contribution to climate change at both local and global level as our growing environmental footprint is driving higher levels of emissions. We currently track Tullow's atmospheric emissions from production, drilling and well test activities. Atmospheric emissions comprise Carbon Dioxide (CO2) and Methane (CH4). We have had Group-level assurance of our emissions data for four years.

We are currently working to minimise our operational impact on the environment through energy efficiency initiatives, monitoring and evaluation activities, emissions management programmes, effective planning of operational life cycles through ESIAs and compliance with national and international requirements. As a matter of course we incorporate emissions control in the design phase of all major projects and developments. Our IMS incorporates and underpins our environmental commitment to minimise pollution and emissions. IS014001 certification requires Tullow to commit to avoiding releases as well as demonstrate continual improvement in environmental performance.

Gas flaring in Ghana

Gas flaring

The final EIS for Jubilee Phase 1 documented flaring activity for First Oil production and stabilising FPSO plant and processes as part of commissioning. Final stages of commissioning include completing the overall gas injection compression facilities. These are required to enable the produced/associated gas to be re-injected into the reservoir as the only available gas disposal route at this time.

The compression system is a complex engineering set-up and the current status is that we expect to achieve full gas injection in the near future. On achieving this, we will enter a period of securing system performance and stability. Given this status it will be necessary to flare additional associated gas in excess of the originally proposed volume estimates in the Final EIS. We are in regular communication with the Ghanaian Environmental Protection Agency on this subject.

The long-term plan is that there will be no continuous flaring of hydrocarbon gases during normal operations. There will only be a pilot light so that the flare will be available in the event of an emergency shutdown.

All flaring activities whether onshore or offshore are an integral part of ESIAs submitted to national regulators. Our subsequent environmental management plans detail the arrangements for each operation outlining the mitigation, monitoring and management of all our environmental risks. Where we have a licence interest but are not the operator, we seek to engage with our partners to minimise flaring and other environmental risks in the course of normal operations.


Estimated GHG emissions from the Jubilee Phase 1 development are documented in Table 5.9 in the Final Environmental Impact Statement (EIS), which is available online at www.tullowoil.com/ghana/finaleisjubilee
