Assembly Bill 481, introduced in the Nevada State Legislature on March 24, 2025, aims to address the pressing issue of greenhouse gas emissions from the aviation sector. The bill recognizes that large subsonic jet aircraft and propeller-driven airplanes contribute significantly to greenhouse gas emissions, accounting for 10% of emissions from the transportation sector and 3% of total emissions in the United States.

The legislation highlights the detrimental effects of climate change on Nevada, including increased temperatures, prolonged droughts, and heightened wildfire risks, which threaten public health and the state's economy. The bill emphasizes the need for a transition to a low-carbon aviation transportation sector, positing that such a shift could foster economic growth and diversification in Nevada.

Key provisions of Assembly Bill 481 include the establishment of a state program to promote the production and purchase of sustainable aviation fuel. This initiative is designed to incentivize air carriers to adopt greener practices without the state acting as a guarantor for any debts incurred by these carriers.

Debate surrounding the bill has focused on its potential effectiveness and the economic implications of transitioning to sustainable aviation fuel. Supporters argue that the bill is a necessary step toward reducing emissions and combating climate change, while critics question the feasibility of the proposed incentives and the overall impact on the aviation industry.

The bill's passage could have significant implications for Nevada's environmental policies and economic landscape, particularly in light of the state's reliance on tourism and outdoor activities, which may be adversely affected by climate change. As discussions continue, stakeholders are closely monitoring the bill's progress and its potential to reshape the aviation sector in Nevada.
