Definition
The Cosmic Development Goal Index (CDG Index) is a comprehensive metric designed to assess the degree to which space exploration and development align with principles of sustainability and cosmic ethics across economic, social, and environmental dimensions. It extends the concept of the Sustainable Development Goal Index (SDG Index) into the domain of space, enabling comparative evaluation of the responsibility and soundness of space activities by nations and organizations.

Rationale

Rising potential for ownership and usage disputes due to intensified competition over space resources
Risks of environmental degradation from unregulated exploration, mining, and debris generation
Need to prevent militarization and conflict in space development
Establishing an international norm for developing space in a way that ensures “no death, no war, no harm, no suffering”

Evaluation Categories (adapted from René Passet’s three pillars)

Economic – Economic efficiency of space development, contribution to international cooperation, balance of public and private investment
Social – Assurance of peaceful use, creation of education and employment opportunities, technology sharing, and improved accessibility to space
Environmental – Minimization of space debris, protection of celestial bodies and ecosystems, reduction of carbon emissions and energy consumption

Proposed Implementation

Annual publication of a CDG Index Report by country and organization
Awarding “Model Space Development” certifications to top-performing nations and institutions
Incorporating index results into international space agreements and policy-making
Encouraging the application of the index to private-sector space projects

Expected Outcomes

Establishment of ethical standards for space development
Prevention of international disputes over space resources
Guarantee of environmental sustainability in outer space
Transformation of space development into a shared human achievement—cultural, artistic, and philosophical as well as scientific
