The settlement is significantly higher than a previously announced deal in which BP was set to pay USD 18.7 billion to resolve claims from US government entities.
"This historic resolution is a strong and fitting response to the worst environmental disaster in American history," Lynch said at a press conference.
"BP is receiving the punishment it deserves, while also providing critical compensation for the injuries it caused to the environment and the economy of the Gulf region."
It took 87 days to cap BP's runaway well - some 1,500 meters below sea level off the coast of Louisiana.
Beaches were blackened in five states and the region's tourism and fishing industries were crippled in a tragedy that riveted the nation.
The global settlement resolves the governments' civil claims under the Clean Water Act and natural resources damage claims under the Oil Pollution Act, as well as economic damage claims of the five Gulf states - Texas, Louisiana, Mississippi, Alabama and Florida - along with hundreds of local governments.
"We are committed to ensuring the Gulf Coast comes back stronger and more vibrant than before the disaster. If made final, the settlement will provide the US and Gulf states with the resources and certainty needed for effective restoration planning and improvements.
