How Aramco created commercial value utilizing novel approaches to carbon accounting

Aramco has demonstrated how robust carbon accounting and verified carbon credits can be integrated into physical energy transactions. Its first commercial sale of a verified carbon-offset crude cargo shows how credible carbon intensity methodologies could support greater transparency and commercial differentiation.

How Norway’s 1971 petroleum principles shaped Equinor’s low-emission production on the Norwegian continental shelf 

Norway’s long-standing approach to limiting gas flaring has helped establish a framework focused on resource utilisation and lower-emission production. Equinor’s experience demonstrates how minimizing flaring and maximizing resource utilization have contributed to effective methane management and the efficient use of energy.

Aramco’s Use of Agentic AI and energy efficiency tools reduces emissions​

Aramco is using agentic AI, digital technologies and targeted energy-efficiency measures to improve operational performance and reduce emissions. In 2025, its initiatives delivered approximately 3,192 MMBtu/hr in energy savings and avoided 1.57 MtCO₂e.

Enilive’s HVO diesel biofuel successfully tested for maritime transport

Eni and MSC Cruises have successfully tested Enilive’s HVO diesel as a practical solution for reducing emissions from maritime transport. The trial powered an MSC Opera engine with pure HVO for approximately 2,000 hours, delivering comparable performance to traditional marine fuels while reducing NOx emissions by 16% and GHG emissions by around 80%.

Advancing methane management through integrated data

Oxy is bringing together emissions data from satellites, aerial surveys, ground sensors and operational systems to strengthen methane management. Its integrated platform helps teams identify and prioritise emissions events, coordinate responses and turn complex data into actionable insights.

bp turns methane measurement into targeted action 

bp is combining source-level methane measurement with continuous monitoring, surveys and operational data to identify emissions and target action. In 2025, this approach helped deliver an estimated 456 tonnes of methane reductions through operational improvements, without requiring capital investment.

From flaring to power: innovative gas recovery

Whilst flaring can often be reduced by optimising existing operations, it sometimes requires substantial investments.
