From January 2019, the Journals Nature and Scientific Data will require that authors of papers in Earth sciences (and related space and environmental science fields) make supporting data available to others through community repositories where available. To support authors and incentivize data sharing, standardized research-data policies and the Research Data Helpdesk, which provides free advice on research-data policies and data repositories, are in place now.

Publishers, geoscience societies/communities, datacenters support open and FAIR data
The requirement for data publishing is one of the commitments for publishers which are outlined in the Commitment Statement in the Earth, Space and Environmental Sciences that was signed now by Nature and Scientific Data. The statement was prepared by the ‘Enabling FAIR Data initiative in the Earth, space and environmental sciences’, a community-driven initiative that brings together a network of stakeholders who, through advocacy, policies, infrastructure and services to support data sharing, are working together to facilitate a shift towards open data becoming the default in the Earth sciences. Have a look at all signatories of the Commitment Statement.
