The summit will focus on momentum and ambition, economic opportunity, green finance and innovation to combat climate change.
US President Joe Biden will aim to kick-start a crucial year of action on climate change today as he hosts 40 world leaders at an Earth Day summit.
The virtual White House meeting coincides with Mr Biden's expected promise to slash America's greenhouse gas emissions by at least 50% by 2030, nearly doubling its previous target.
The pledge and the summit represent a concerted US effort to reclaim credibility and leadership on climate change after four years of inaction under Donald Trump.
A senior official said the Biden administration is increasing its own targets in order to more effectively convince other countries to do the same.
They said the summit will focus on momentum and ambition, economic opportunity, green finance and innovation, and that "the expectation for all countries is that ambition has to be increased immediately".
The White House summit is the first major inflection point in a series of high stakes opportunities for progress on climate change, from the G7 and G20 meetings over the summer and autumn to an important United Nations climate meeting hosted by the UK in Glasgow in November, known as COP26.
