During the 2024 UN Climate Change Conference (COP 29), the United States showcased its commitment to climate action by endorsing multiple declarations aimed at addressing various aspects of the climate crisis. The endorsements included the COP 29 Global Energy Storage and Grids Pledge, which sets targets for modernizing grids and increasing energy storage to support the expansion of renewable energy sources. Secretary of Energy Jennifer Granholm represented the U.S. in endorsing this pledge. Another significant endorsement was the COP 29 Hydrogen Pledge, focusing on scaling up clean hydrogen production with a goal of achieving near-zero greenhouse gas emissions, particularly in challenging-to-decarbonize sectors. The U.S. was also involved in initiatives such as the COP 29 Multisectoral Actions Pathways Declaration, emphasizing the importance of resilient and healthy cities through urban climate actions. The commitment to reducing methane emissions, promoting sustainable tourism practices, and addressing water management for climate action further showcased the United States' dedication to tackling climate change on a global scale. The participation of high-level representatives like Secretary Granholm and NASA Senior Counselor Carla McGarvey highlights the importance the U.S. places on these climate initiatives, reflecting a positive sentiment towards collaborative efforts to combat climate change and promote sustainable practices.
