Democratic presidential candidate Elizabeth Warren unveiled a proposal for a Blue New Deal to revitalize coastal economies by building climate change-ready ports, spurring new markets for sustainable seafood and reshaping the offshore energy sector to tap more wind and curtail oil drilling.

The nine-page plan adds to more than half a dozen campaign planks the Massachusetts senator has put forward to lower planet-heating emissions and adapt the United States to the changes already baked in from more than a century of unchecked fossil fuel burning and industrialization.

The proposal stands out as one of the most comprehensive plans yet to emerge to specifically target working waterfronts. Coastal economies were considered a blind spot in the Green New Deal movement that emerged over the past year and calls for a federal climate policy that guarantees good-paying jobs and rapidly transitions the country off fossil fuels. The resolution introduced in Congress in February outlining a Green New Deal made only a passing mention of oceans.

The focus on waterfronts comes as the United Nations climate summit in Madrid pays what activists would call overdue attention to the ways global warming is affecting oceans, which generate at least half of all oxygen in Earths atmosphere and have absorbed an estimated 93% of excess heat from emissions.

While the ocean is severely threatened, it can also be a major part of the climate solution from providing new sources of clean energy to supporting a new future of ocean farming, Warren wrote in a campaign memo outlining the policy. That is why I believe that a Blue New Deal must be an essential part of any Green New Deal helping us fight climate change, protecting our health, and creating good, high-wage union jobs in the process.

The campaign said the proposal did not include new investments beyond the $3 trillion Warren pledged to spend so far on climate efforts. Instead, the Blue New Deal outlines a suite of executive and regulatory actions.
