Associated Press Democratic presidential candidate Washington Gov. Jay Inslee speaks during a primary debate on June 26, 2019, in Miami.

Jay Inslee’s singular focus on climate change isn’t doing much to boost his standing in polls, but the Washington governor’s hefty stack of proposals to curb greenhouse gas emissions and phase out fossil fuels landed him atop a new list ranking of 2020 presidential contenders.

The four tranches of policy released so far by the self-declared climate candidate in the crowded Democratic presidential primary address 41 of 48 components in the rubric left-leaning think tank Data for Progress, which authored one of the first Green New Deal blueprints last year, published Monday morning.

The governor’s plan lacks proposals to eliminate waste, ramp up antitrust enforcement, provide a universal basic income or establish a public bank.

Yet he’s far out ahead of his rivals for the party’s nomination to challenge President Donald Trump next year.

Former Vice President Joe Biden’s climate plan addressed just 25 of the rubric’s 48 components, while acknowledging another six. Massachusetts Sen. Elizabeth Warren’s proposals cover 24 of Data for Progress’s policy concerns, and acknowledges another six. Former Texas Rep. Beto O’Rourke, the first in the race to release a comprehensive climate plan, included 20 of the issues on the rubric, and acknowledged two.

The ranking offers a handy new metric to hold candidates accountable to something beyond rhetorically supporting a Green New Deal.

The list of policies breaks down into seven categories ― low carbon economy, clean air water, land restoration, community resilience, job creation, social safety net and international leadership. The policies listed include holding polluters accountable, curbing methane leakage, banning Arctic oil drilling and guaranteeing a job to every American who wants one.

Eight contenders who vowed to enact a sweeping industrial plan for decarbonizing the nation are marked with gray boxes indicating they “have not yet released climate policy proposal.” The candidates include Sens. Bernie Sanders (I-Vt.), Cory Booker (D-N.J.) and Kamala Harris (D-Calif.).
