    Responsibly

    Let's build the data infrastructure to empower responsible sourcing. Responsible sourcing is hindered by fragmented data pipelines. The task of evaluating millions of suppliers when data fragments across thousands of data sources, standards, parameters, geographies and industries is immense. Responsibly is here to help. We're building the data infrastructure to help all players connect. We want buyers to have the transparency they need to make decisions. Suppliers should only need to update one profile. Data providers should easily be able to find users for their data. Procurement software shouldn't need to build hundreds of integrations. There are duplicated efforts everywhere, and too many spreadsheets to count. Responsibly is starting a movement to synchronize and collaborate, and we'll publish much of our infrastructure open source, for all to enjoy. Streamline your supplier data pipeline and reduce admin costs.

    Early Phase Integrated Carbon (EPIC) Assessment
    The Early Phase Integrated Carbon (EPIC) assessment is a whole life carbon tool built by EHDD to support climate-positive design decisions in early project phases when data is scarce but the potential for emissions reduction is high. To overcome the scarcity of data, EPIC uses a model that combines regionally-specific background data, forward-looking projections, peer-reviewed findings, and common sense assumptions to assess the relative impact of a variety of carbon reduction measures on a project’s embodied, operational, and landscape carbon footprints. EPIC is designed to allow a user to enter a strict minimum of project parameters and to test a wide range of the most meaningful carbon reduction strategies. EPIC is available both as an open access web application or via paid access to our API.
