On 7 December the Costa Cruises Group signed the Biomethane Declaration that was presented to the European Commissioner for Energy, Kadri Simson.

Biomethane, the most sustainable and scalable gas available today, is used in all aspects of the economy - from industry to energy, transport and buildings - as well as helping to develop farming systems and create related jobs.

These traits are what make it an exceedingly valuable transition fuel and, until "zero-emissions" technologies are fully available, biomethane has the potential to be a decisive factor in achieving the target reduction of greenhouse gas emissions contained in the "Fit For 55” package of European measures (55% less by 2030). To achieve this, its use must be increased through larger investments, political support, cost reduction, and the creation of complete supply chains.

In light of this, the signatories of the Declaration - 28 European companies and organisations - are committed to doing their part by mobilising the biomethane supply chain to increase its application to at least 350 TWh (33 billion cubic metres) by 2030, the European Commission's estimated capability, which would eliminate approximately 110 Mt of CO2 emissions known as Scope 3 emissions.

This is another important step towards a zero-emissions ship that calls for everyone to show their commitment and play their part.
