Biden claimed that his biggest benefit to the evolution of climate policy would be defeating President Trump and taking back the White House for Democrats.
The President's challenges in Rust Belt states, critical to his narrow 2016 victory, are at the forefront of advisers' minds.
But the Senate veteran who has emerged as a Democratic Party eminence appeared to bypass the jockeying with his Democratic rivals, as he geared up for a titanic general election battle against Trump.
The former vice president kickstarted his presidential bid with a call for fairness and equality in the United States, requesting voters to end the partisan conflicts and pettiness that has left Americans miffed in the recent past.
It is some distance, Mr. Cole added, "an ideal distance from Ronald Reagan and 'Morning in The US'". "That they are angry, and the angrier you are, the better", Mr Biden will say, according to excerpts of his address released in advance.
"You will not hear me speak ill of another Democrat", Biden said.
Iran FM holds talks with Sushma Swaraj amid tensions with US
Iran is its third largest supplier after Iraq and Saudi Arabia and meets about 10 per cent of its total needs. Zarif, who is on a two-day visit to India, had said the United States is escalating tensions "unnecessarily".
The state's Republican party released a statement in response to Biden's campaign announcement calling his campaign one that "seeks to paint over the failures of the Obama-Biden years and his record as US senator while offering nothing but a continuation of those failed policies".

In the RealClearPolitics polling average, Biden leads Sanders by 18 points. "Joe represents a sort of a more middle ground where we can bring people together instead of becoming more and more fractious". 'We need to remember that today, I think, more than any time in my career'.
The president's visit to Pennsylvania, meant to boost Republican congressional candidate Fred Keller's prospects over Democrat Marc Friedenberg in a Tuesday special election for an open seat, had as much to do with helping his own chance for reelection as it did with pushing Keller over the finish line.
"I look at Joe, I don't know about him", Trump told reporters last week. Notable attendees included Miami-Dade County commissioners Daniella Levine-Cava and Sally Heyman, City of Miami commissioners Ken Russell and Keon Hardemon, former Miami Mayor Manny Diaz, former Miami-Dade County Mayor Alex Penelas, Miami-Dade State Attorney Katherine Fernandez Rundle and State Rep. Joe Geller (all Democrats).
Biden also answered critics who have mocked his pledge to work with Republicans as unrealistic should he win the White House. Compared with events held by some of his top rivals - and certainly Trump's rallies - the crowd was large, but not overwhelming.
