The KM3 Neutrino Telescope 2.0 (KM3NeT 2.0) is a multi-site Research Infrastructure housing a next generation neutrino telescope. Located in the deepest seas of the Mediterranean, KM3NeT 2.0 will explore the neutrino Universe and also study the properties of the elusive neutrino particle. Arrays of thousands of optical sensors detect the faint light emitted in the deep sea by the passage of charged particles originating from collisions of the neutrinos and the Earth. The facility will also house instrumentation for Earth and Sea sciences for long-term and on-line monitoring of the deep sea environment and the seafloor at depth of several kilometers. With the giant ARCA telescope, KM3NeT 2.0 scientists will search for cosmic neutrinos from distant astrophysical sources such as supernovae, gamma-ray bursters or colliding stars. With the compact ORCA detector the oscillation behaviour and mass ordering of the neutrinos will be studied exploiting neutrinos generated in the Earth’s atmosphere. In the ESFRI Roadmap since 2016, KM3NeT 2.0 is in the Implementation Phase but already is providing interesting results as construction proceeds.

Three suitable deep-sea sites are identified, namely going from west to east, KM3NeT-Fr, off-shore Toulon (France), KM3NeT-It, off-shore Portopalo di Capo Passero (Italy) and KM3NeT-Gr, off-shore Pylos (Greece). The first phase of construction of the KM3NeT 2.0 Research Infrastructure began in 2015 at the KM3NeT-It and KM3NeT-Fr sites and is expected to be finished in 2028. For this a Letter of Intent for KM3NeT 2.0 has been published and a Memorandum of Understanding has been signed by all participating funding agencies. Within the framework of KM3NET-INFRADEV2 (EU-HORIZON programme) the Collaboration is aiming to adopt an AISBL legal entity in the near future.
The KM3NET RI provides to its collaboration members and the world-wide Astroparticle community information on the directions, energies and flavour of its detected neutrinos. Deep sea optical and acoustic noise data is made available to the Earth and Sea science community.

The KM3NeT Collaboration has established MOUs with several other astronomical observatories (IceCube, CTA, HESS, LHASSO, HAWC, Fermi, SVOM, Master, Grandma, etc). The KM3NeT sites are part of the EMSO Consortium. KM3NeT is involved in several EU projects with other RIs: ASTERICS, ESCAPE, REINFORCE, EOSC, OSCARS, ACME.
