The bill concerns the deliberate release of pollutant emissions.
When we search for the claim on the internet using keywords, we come across a bill titled "NH HB1700" in the US state of New Hampshire. Some foreign users interpreted this bill as "banning chemtrails".

Chemtrails is a conspiracy theory that claims that the tail trails left behind by airplanes are actually toxic gases. However, these white trails are actually formed when water vapor and jet fuel from airplanes condense rapidly at low temperatures and turn into ice crystals. Just like the vapor that comes out of our mouths in cold weather.

On December 19, 2023, a bill was introduced in the New Hampshire State Assembly. The bill would "prohibit the intentional release of pollutant emissions, including stratospheric aerosol injection (SAI), cloud seeding, weather modification, extreme electromagnetic radio frequency and microwave radiation." 

The bill goes on to say the following:

"The commissioner of the department of environmental services, upon discovery of stratospheric aerosol injection (SAI), cloud seeding, weather modification, or other atmospheric polluting activities, including emissions of excessive electromagnetic radio frequency/microwave (RF/MW) radiation, shall immediately issue a cease and desist order if an agency, department, office, program, or member of the public provides evidence to the department or New Hampshire county sheriffs that the activity may be harmful or involves the release of a pollutant emission. "

The activities listed in the bill, such as stratospheric aerosol injection (SAI), which aim to reverse some of the effects of climate change by altering environmental conditions, are called geoengineering. 

Although conspiracy theorists equate geoengineering with "chemtrails", they are two different things.

SAI, a project to reduce the effects of global warming

SAI is an attempt by climate scientists to find a theoretical solution to the climate crisis. The idea is that injecting thousands of tons of sulfur dioxide or light-reflecting particles into the stratosphere will allow some of the sun's rays to be reflected back. In this way, it is thought that the planet could be prevented from further warming and even cooled down to some extent.

However, there is no consensus in the scientific community on whether this solution will work. Some scientists are concerned about the possible side effects of the gases that would be released into the atmosphere. In addition, practical difficulties pose various obstacles to testing the theory in real life. 

The most notable of these challenges is how sulfur dioxide will be released into the stratosphere. 

Although it is thought that specially designed aircraft that can fly twice as high as commercial planes could be used for this, Dr. Hugh Hunt from the University of Cambridge says this is not a very good idea. He says that thousands of flights would have to be made every day to release enough material, and that this alone would release too much carbon dioxide into the atmosphere. According to Hunt, who is also part of the Stratospheric Particle Injection for Climate Engineering research, a 20-kilometer-high hose with a hydrogen balloon could facilitate this application.

Government bans SAI after first application in Mexico

Something similar to Dr. Hunt's proposal was implemented in December 2022. Make Sunsets, an environmental technology startup founded by Luke Iseman, released helium balloons filled with sulfur dioxide into the sky in the Mexican state of Baja California. This was the first time a non-theoretical experiment on SAI was conducted. 

After the experiment, Mexico's Ministry of Environment and Natural Resources banned further experiments as part of the project. Mexican authorities justified the ban on the grounds that such experiments could cross national borders and that there is no international treaty defining the scope of such work.

Following this ban, many users on social media have posted that Mexico has banned chemtrails.

However, the chemtrails conspiracy theorists who make these claims lie to themselves. Because the images of tail trails allegedly showing "chemtrails" in Mexico are still being shared on social media.

The claim that Texas has banned chemtrails is just a petition started by chemtrails conspiracy theorists.
