Our work has two pillars.
Hourglass’s strategy for advancement of the mCDR field is focused on two main pillars of development, (1) tool building for responsible carbon removal project planning, permitting and Measurement, Reporting, and Verification (MRV) and (2) proof-of-concept field trials through both novel project development as well as independent monitoring and/or data analysis of third-party projects. Together, these work streams de-risk the key uncertainties on how to safely and effectively scale mineral-based OAE techniques.

The below policy establishes Hourglass Climate’s guidelines for the allocation and reimbursement of indirect costs associated with projects and activities funded by external grants and contracts. Indirect costs, also known as overhead costs or Facilities and Administrative (F&A) costs, are those expenses that are not directly attributable to a specific project or activity but are necessary for the general operation of the organization. These costs may include utilities, administrative salaries, office supplies, and maintenance expenses.
Policy Statement: The maximum allowable indirect cost rate is 10% of the total direct costs of the project or activity. This rate applies to all external grants and contracts unless otherwise specified by the funding agency or sponsor.
