Longtime New York gubernatorial candidate Howie Hawkins will seek the Green Party nomination for president in 2020.

Hawkins, who make the announcement on Tuesday in Brooklyn, has run for governor three times (in 2010, '14 and '18) on the Green Party's line, every time clearing the 50,000-vote limit required to maintain the party's ballot status. He launched his exploratory committee for the presidency in April.

Hawkins, a retired Teamster, has also run for Congress and the U.S. Senate, as well as seeking local offices in Syracuse.

The centerpiece of Hawkins' campaign for president is an "ecosocialist Green New Deal" to convert to clean renewable energy with zero greenhouse gas emissions by 2030 — a "World War II-scale mobilization," he said in a statement.

"The climate crisis is an existential threat to humanity. Real solutions can't wait," Hawkins said in a statement. " ... The Green New Deal is the program of hope that we can rally around to beat the ultra-right's program of fear based on racism, xenophobia, religious bigotry, fact-free irrationalism, and authoritarianism. It's how we beat the politics of Trumpism."

While a number of Democratic candidates have addressed the concept of a "Green New Deal," the particulars of their plans tend to vary.

Referring to U.S. Rep. Alexandria Ocasio-Cortez's efforts to push for such a plan, Hawkins said "they took the brand but watered down the content. Then the Democratic leadership shot it down anyway."
