A coalition of environment-focused organizations launched a platform Tuesday aimed at establishing principles around sun-reflecting technologies, as interest in experimenting with geoengineering grows and attracts more political scrutiny.

The platform will grow to offer a series of tools in the coming months — such as standardized ways for reviewing projects, disclosing them to the public and providing oversight — in an effort to make solar geoengineering more transparent and accessible.

The goal of theSolar Geoengineering Research Governance platform is to build consistency into a growing field of research that is often perceived as a risky way to lower the Earth’s temperature.

“We’re showing that good governance is possible because we’re creating the mechanisms to comply by them,” said Shuchi Talati, executive director of the Alliance for Just Deliberation on Solar Geoengineering, one of several groups behind the platform.
