If the sea could talk to us, what would it say?

It would tell us it’s under threat from climate change – and ask us all to work together to preserve it by reducing greenhouse gases.
"I sustain you more than you know."

The sea does so much for us

The sea feeds us. It transports 90% of all globally-traded goods. It absorbs huge quantities of CO₂. Without it, the planet would be six to eleven degrees warmer. And every second breath we take comes from the oceans.

Decarbonizing the sea: it’s time to turn the tide

"The ships that sail on me need to change."

But the sea is being harmed by those who use it

Shipping is one of the least emission-intense forms of transport. But the sheer size of the maritime sector means that it produces more emissions than the aviation industry.


It produced over one billion tons of CO₂ in 2018. And it’s predicted that shipping will account for 17% of global carbon emissions by 2050 if nothing changes.


These greenhouse gases obviously contribute to climate change – and this has a direct effect on the sea:

The need to reduce emissions is therefore urgent.

Slower sailing speeds are one way to help, but this is hard to implement in today’s fast-moving, want-it-yesterday world.


More effective solutions include new fuels, new technologies and new ship designs.


These solutions require close collaboration between governments, companies and even competitors. We have developed and fostered many such partnerships, with e-fuel producers, shipping companies, boat builders, port authorities and more.


After all, we’re all in the same boat when it comes to climate change.

A study on the electrification of the European Ferry Fleet 

A study conducted by Siemens Energy and the non-profit environmental organization Bellona shows that Europe can reduce CO₂ emissions in key countries by nearly 50 percent. This would save 800.000 tons of CO₂ each year, thanks to already available technologies.  

Views of the sea

With so many businesses depending on the sea, it’s everyone’s business to preserve it. Collaboration across all marine sectors enables projects that would otherwise not exist. And it accelerates decarbonization, for the ocean and for the whole planet.





A decarbonized energy system is possible if we all embrace this vision.

We aspire a net zero value chain and have committed to reduce greenhouse gas emission from the use of products sold by 28 percent until 2030.
