Wind and solar energy. That’s renewable. But for them to power a global energy transition, we’re making sure their delivery is sustainable too.

In helping the world to meet all its energy needs sustainably, we are leading by example – by putting sustainability at the centre of everything we do.

That means minimising the impact of our projects and supply chains on the environment, maximising the social wins of a green economy in our communities, and leveraging good governance in our workplace to seize opportunities in the marketplace.

Living up to our environmental, social, and corporate governance (ESG) responsibilities is not a ‘nice to have’ badge of business honour – it’s a ‘must-do’ to drive a fair, inclusive energy transition and limit global warming to 1.5oC.

The three-year initiative – known as MARine COexistence scenario building, or Marco – aims to develop a scalable system model toolbox for determining and forecasting marine coexistence between different users of the ocean and marine ecosystems.
