Shut Down DC is a coalition of environmentalist activist groups which announced plans to significantly disrupt traffic in Washington, D.C. on September 23, 2019 to bring awareness to climate change. The group has stated that it aims for its demonstrations to affect the most powerful people in the city by blocking what they believe to be key intersections for politicians and other areas of note. As of September 13, about 250 people had confirmed they would join in the demonstrations. 
The group is sponsored by All Out D.C., a network of activists that formed after the inauguration of President Donald Trump. All Out D.C. has hosted rallies involving Antifa members in the past, causing D.C. police to prevent violent interactions between them and right-wing demonstrators, including the Proud Boys.  Additional sponsors include Rising Tide North America, Extinction Rebellion Washington DC, and CCAN Action Fund. 
Shut Down DC’s website claims to be a part of the “Global Climate Strike 2019,” a worldwide movement of environmentalist groups that plan to go on strike from school or work and block traffic during the week of September 20, 2019. “This is the mass uprising that everyone with climate anxiety has been waiting for,” its website states.  Extinction Rebellion, an environmentalist group headquartered in the United Kingdom, held similar demonstrations in the streets of London for a week in April 2019. 
Shut Down DC has aligned its demands with the platform put forward by Strike With Us, which includes the Green New Deal, halting all fossil fuel extraction and planned infrastructure projects, and advocating for lawmakers to introduce legislation for the so-called “Rights of Nature” which would include a ban on resource extraction.  Shut Down DC has also stated that the only way to fight climate change is to also “decolonize and democratize our communities.” 
On September 11, 2019, Shut Down DC blocked traffic on the intersection of Florida Avenue and R Street. north of the Dupont Circle neighborhood in Washington, D.C. The protesters allegedly did not move out of the way for a man on his way to the hospital to visit his wife, which led to a screaming match. 
Patrick Young, one of the main organizers of the group, stated that Shut Down DC, a coalition of at least 24 different groups, aims to have decentralized leadership so that it can resist hypothetical efforts by law enforcement to arrest the main leaders.  According to a press release, these groups include 198 Methods, 350 DC, Backbone Campaign, Beyond Extreme Energy, Black Lives Matter DMV, Chesapeake Climate Action Network Action Fund, Code Pink, Extinction Rebellion DC, Friends of the Earth Action, Friends Meeting in Washington Social Concerns Committee, Labor Network for Sustainability, Metro DMV Democratic Socialists of America, Movement for a People’s Party, and Rising Tide North America. 
Young himself is a senior research analyst at the International Brotherhood of Teamsters.  He had worked at Rising Tide for 15 years where he organized various climate change demonstrations and events.  
On September 18, activist and author Naomi Klein and Rev. Lennox Yearwood Jr., CEO and president of Hip Hop Caucus, attended a meeting with members of Shut Down DC to build support for the movement.
