The JAC is a bi-national committee charged with the development and recommendation of air quality improvement initiatives to the Air Work Group established under the "Agreement Between the United States of America and the United Mexican States on the Cooperation for the Protection and Improvement of the Environment in the Border Area." The "La Paz" agreement was signed on August 14, 1983 in La Paz, Baja California, Mexico.
On May 7, 1996, the United States and Mexico signed an unprecedented agreement that defined the bi-national Paso del Norte Air Basin and created the committee. It is comprised of a mixture of federal, state, and local government officials along with private citizens, university officials, and non-governmental organizations from the United States and Mexico.
“Develop, promote, and recommend to the La Paz Agreement Air Work Group air quality planning and management strategies to ensure a reduction in air pollution concentrations for public health and welfare of residents of the Paso del Norte air basin, recognizing the importance of the participation of local communities in carrying out this mission.”
