What changed between versions

SB189 Original → SB189 Act 601 · 4 edits
MODERATE
This bill updates the Louisiana statute prohibiting the intentional release of substances to alter the climate. The primary change is the addition of 'burning fuel in an aircraft engine' to the list of prohibited methods, explicitly targeting geoengineering activities like solar radiation management. The bill also clarifies the scope of prohibited substances to include 'apparatus' and expands the list of affected environmental factors to include 'sunlight intensity.'
Scope change
The scope of prohibited actions was expanded to explicitly include the burning of fuel in aircraft engines for the purpose of climate modification, which was not explicitly detailed in the previous version.
