Request

Request received: 19 April 2025

Under the Environmental Information Regulations 2004 (EIR) and the Freedom of Information Act 2000, I am formally requesting the immediate disclosure of all information held by NERC regarding Solar Radiation Management (SRM), geo engineering, atmospheric aerosol injection, and any related climate modification activities conducted or supported either directly or indirectly within the United Kingdom or surrounding European territories, including maritime zones.

This request specifically includes, but is not limited to, all research, contracts, partnerships, deployments, environmental assessments, correspondence, data, and risk reports regarding the deliberate alteration of the atmosphere or marine environment by means of reflective particles, chemical sprays, or other climate-altering technologies. If SRM and related activities are taking place, I demand a full breakdown of:

1. The types of materials or metals (e.g., aluminium, barium, strontium, etc.) used or tested.

2. The purpose of these materials and who authorised their use.

3. The environmental impact assessments carried out beforehand.

4. The agencies or private contractors involved in execution or research.
