The Carbon Sequestration Leadership Forum (CSLF) is an international initiative to advance carbon capture and storage (CCS) technology. The Forum is a Ministerial-level organization that includes 23 member countries and the European Commission. Membership is open to national governmental entities that are significant producers or users of fossil fuel and that have a commitment to invest resources in research, development and demonstration activities in carbon dioxide capture and storage technologies. CSLF also recognizes that stakeholders, those organizations that are affected by and can affect the goals of CSLF, form an essential component of CSLF activities.The CSLF Charter, signed in June 2003, organized the CSLF by creating a Policy Group, which governs the overall framework and policies of the CSLF, a Technical Group, which reviews the progress of collaborative projects and makes recommendations to the Policy Group on any needed actions, and an administrative Secretariat, which organizes CSLF meetings, coordinates communications among CSLF Members, and acts as a clearinghouse of information. In July 2005, the G8 Summit endorsed the CSLF in its Plan of Action on Climate Change, Clean Energy and Sustainable Development, and identified it as a medium of cooperation and collaboration with key developing countries in dealing with greenhouse gases.Similar designations were also made in bilateral activities that include: the joint statement of the U.S.-European Union Summit on Energy Security, Energy Efficiency, Renewables and Economic Development, and the Mainz Declaration of Germany and the United States on Cleaner and More Efficient Energy, Development and Climate Change.In 2006 and 2007, the International Energy Agency and the CSLF held a series of three workshops for invited experts from around the world on the topic of near-term opportunities for carbon capture and storage. Resulting recommendations from these workshops were formally adopted by the CSLF and were sent forward to G8 leaders. The CSLF has recognized 30 carbon capture and storage projects worldwide that demonstrate a wide range of CO2 capture, transport and storage research and activities.

The United States Department of Energy (DOE) is an executive department of the U.S. federal government that oversees U.S. national energy policy and manages the research and development of nuclear power and nuclear weapons in the United States. The DOE oversees the U.S. nuclear weapons program, nuclear reactor production for the United States Navy, energy-related research, and domestic energy production and energy conservation. The DOE was created in 1977 in the aftermath of the 1973 oil crisis. It sponsors more physical science research than any other U.S. federal agency, the majority of which is conducted through its system of National Laboratories. The DOE also directs research in genomics, with the Human Genome Project originating from a DOE initiative.The department is headed by the Secretary of Energy, who reports directly to the president of the United States and is a member of the Cabinet. The current Secretary of Energy is Jennifer Granholm, who has served in the position since February 2021. The department's headquarters are in southwestern Washington, D.C., in the James V. Forrestal Building, with additional offices in Germantown, Maryland.

The Office of Intelligence and Counterintelligence (OICI), also abbreviated IN, DOE-IN, DOE/IN, I&CI, or OIC, was established in 2006 by the merger of pre-existing Energy Department intelligence and security organizations. It is an office of the United States Department of Energy (DOE) responsible for all intelligence and counterintelligence activities throughout the DOE complex; due to this central role, OICI is designated DOE's Headquarters Intelligence. As a component of the United States Intelligence Community in addition to the Department of Energy, OICI reports to both the Director of National Intelligence and Secretary of Energy.

The National Museum of African Art is the Smithsonian Institution's African art museum, located on the National Mall of the United States capital. Its collections include 9,000 works of traditional and contemporary African art from both Sub-Saharan and North Africa, 300,000 photographs, and 50,000 library volumes. It was the first institution dedicated to African art in the United States and remains the largest collection. The Washington Post called the museum a mainstay in the international art world and the main venue for contemporary African art in the United States. The museum was founded in 1964 by a Foreign Service in Capitol Hill. The collection focused on traditional African art and an educational mission to teach black cultural heritage. To ensure the museum's longevity, the founder lobbied the national legislature to adopt the museum under the Smithsonian's auspices. It joined the Smithsonian in 1979 and became the National Museum of African Art two years later. A new, primarily underground museum building was completed in 1987, just off the National Mall and adjacent to other Smithsonian museums. It is among the Smithsonian's smallest museums. The African art museum took a scholarly direction over the next twenty years, with less social programming. It collected traditional and contemporary works of historical importance. Exhibitions include both internal and borrowed works and have ranged from solo artists to broad survey shows. The museum hosts two to three temporary exhibitions and ten special events annually. The preferred abbreviation for its name is NMAfA.

The Arts and Industries Building is the second oldest (after The Castle) of the Smithsonian museums on the National Mall in Washington, D.C.

After being closed since 2004, the building reopened in 2021 with a special exhibition, Futures, scheduled to run through July 2022.

The Arthur M. Sackler Gallery is an art museum of the Smithsonian Institution in Washington, D.C., focusing on Asian art. The Sackler Gallery and the Freer Gallery of Art together form the National Museum of Asian Art in the United States. The Freer and Sackler galleries house the largest Asian art research library in the country. Founded in 1982, the Gallery is named after Arthur M. Sackler, who donated approximately 1,000 objects and $4 million to the building of the museum. Located on the south side of the National Mall, and being physically connected to the Freer Gallery of Art, 96% of the museum is located underground below the Enid A. Haupt Garden. Their donations and contributions have been protested by people who accuse them of being a key contributor to the opioid epidemic in the United States.

The Hilton Washington DC National Mall The Wharf, previously known as the L'Enfant Plaza Hotel, is a 367-room hotel located on the top four floors of a 12-story mixed-use building in downtown Washington, D.C., in the United States. It was designed by architect Vlastimil Koubek, and was opened on May 31, 1973, as the Loews L'Enfant Plaza Hotel, named after Pierre Charles L'Enfant, the first surveyor and designer of the street layout of the city. The hotel sits atop L'Enfant Plaza, an esplanade and plaza structure erected above a highway and a parking garage in the Southwest quadrant of the District of Columbia. The plaza and hotel were approved in 1955, but construction did not begin on the plaza (on which the hotel sits) until 1965. The plaza and esplanade were completed in 1968. The start of construction on the hotel was delayed three years, and was completed in May 1973. The construction led to a lawsuit after it was found that the foundation of an adjoining structure had encroached on the hotel's property. The hotel suffered a serious fire in 1975 that claimed the lives of two people. L'Enfant Plaza Corp., which owned the hotel, sold the structure to Sarakreek Holdings in 1998, which in turn sold it to the JBG Companies in 2003. A legal battle ensued over the hotel's ownership. The hotel's original operator, Loews Hotels, was replaced after thirty-two years by Crestline Hotels & Resorts in 2005, which was in turn replaced by the Davidson Hotel Company in 2010. The hotel closed on December 3, 2013, for what was originally intended to be a year-long overhaul and upgrade of the entire property. It reopened on April 1, 2019, as the Hilton Washington DC National Mall.
