Sustainability

We aim to conduct our business activities with no harm to people, minimal impact on the environment and no accidents, today and in the future.

Value creation and sustainability

Sustainable growth is built on value creation that benefits not just shareholders, but the entire stakeholder community.

To achieve this, we have developed an agreed code of ethics and sustainable development policies that govern the Group’s approach to the environment, stakeholder relationships, health and safety, human resources management and procurement policies. Everyone who works for us is expected to conform to these policies.

Sustainable growth

Our sustainable growth strategy identifies development opportunities that address environmental and societal problems. We aim to meet people’s energy needs while limiting the consumption of natural resources.

We minimise our impact on the environment through pollution prevention, reduction of natural resource consumption and emissions, and the reduction and recycling of waste. We are committed to ongoing improvements to achieve best practice on all environmental issues.

In the UK, we assess and minimise our environmental impact through an integrated management system (IMS) certified against ISO 14001. We aim to extend ISO 14001 certification to all parts of the Group in future years.

Limiting energy consumption is a priority. We devise and implement energy-efficient solutions consistent with our commitment to meet global energy needs.

Our German operation gained ISO 50001 certification in 2014. It has installed combined heat and power (CHP) units and reduced flaring at numerous locations. It generates surplus electricity and supplies the national grid.  Net purchased electricity has declined by around 10 GWh annually.

The Gjøa floating platform in the northern North Sea, is the first to be powered with hydroelectric power generated sustainably onshore. Electrification of the Gjøa field is delivered through a 100 km submarine cable from Mongstad. It reduces CO2 emissions by about 200,000 tonnes a year.

Capturing carbon in the Dutch North Sea

Our K12-B facility hosted a 12-year experiment to investigate the feasibility of carbon capture and storage (CCS) in depleted natural gas fields. The platform operators worked closely with TNO, a leading Dutch scientific institute. K12-B became a demonstration site, serving as a field lab for a variety of experiments and tests. Over 114,000 tonnes of CO2 was reinjected into the sandstone reservoir 4,000 metres below the water surface. The scientific findings were presented at numerous international conferences.

The low-carbon economy

Natural gas and oil have a substantial share in the global energy mix, providing businesses and households with energy. They will continue to play an important role in global energy demand in the decades ahead.

Neptune is dedicated to understanding, engaging with and contributing to the communities in which we work. We aim to operate safely and responsibly, acting as a good neighbour. We want to be the operator-of-choice and partner-of-choice, providing energy to businesses and households.

Justified concerns about climate change are spurring energy transition to a low-carbon economy. This has led to growing scrutiny of our activities by the public, politicians, governments and regulators. We recognise the urgency of reducing global emissions and are actively pursuing practical solutions.

Limiting methane emissions

The Oil & Gas Methane Partnership (OGMP) is a Climate and Clean Air Coalition (CCAC) initiative. It launched at the UN Secretary General’s Climate Summit in 2014. Neptune is one of the nine partners in OGMP and the only independent in the group.

Methane emissions are less persistent than CO2, but their short-term impact is far greater: 84 times more per tonne in the first 20 years. Reducing methane can have a big impact on total emissions.  OGMP partners produce an eighth of the world’s natural gas. They have identified nine core methane emission sources and are implementing cost-effective measures that have avoided 25,000 tonnes of methane over the last three years.

Neptune’s methane reduction measures include centrifugal compressors with ‘wet’ (oil) seals, glycol dehydrators and hydrocarbon liquid storage tanks. Two of our largest operated assets, Gjøa and Cygnus, are currently participating. We will bring more facilities into the programme in future years.
