When he ran for president, Joe Biden declared climate change the “No. 1 issue facing humanity.” He promised a shift from fossil fuels to renewable energy that would generate millions of new jobs. But will he be able to deliver?

Candidate Biden had the most ambitious plan addressing the climate crisis ever proposed by a major party presidential nominee. His infrastructure and clean energy proposals included a pledge to achieve 100% clean electricity by 2035. That ambitious target is what the science tells us we must do, and a recent analysis reveals it is achievable because of plummeting solar, wind and battery costs.

Biden appears undeterred by the $2 trillion price tag because he sees the climate crisis as an opportunity to create millions of jobs, address systemic inequities and correct environmental problems in communities of color most heavily affected.

But it’s easy to make campaign promises. Now candidate Biden has to pivot to be President Biden. How feasible is it to achieve these goals?

It’s an uphill climb. To achieve his ambitious objective of a “clean energy revolution” means doubling the best rate of solar and wind deployment each year from now to 2029—then tripling it each year to 2035.

This will need to go hand in hand with building a new energy grid, a key part of his plan to create half a million jobs. He will also need to eliminate toxic emissions from the energy-producing sector, which would result in significant health and environmental benefits.

A second pillar of his climate plan relies on reducing greenhouse emissions by setting higher efficiency standards. This focus on efficiency is key because the more energy we save, the less we need to produce with the new renewable sources. It also proposes constructing 1.5 million energy efficient homes to address the affordable housing crisis, which would also create many jobs.

A third pillar, increasing automobile efficiency, involves rebates to trade in gas-guzzling vehicles for more efficient U.S.-made cars and installing half a million EV charging stations.

He proposes an environmental justice initiative that directs 40% of his investment in clean energy directly toward “fence-line” communities populated mainly by racial minorities and indigenous communities that are disproportionately harmed by climate change effects.

When environmental and health costs are added to the balance sheet, a clean energy grid turns out to be a lower-cost option compared to burning fossil fuels.

Even though Biden’s plan might not be as ambitious as the Green New Deal, it is in line with climate scientists’ priorities. If enacted fully, it would result in transformational change.

But while his plan has the right to-do items, how can he make progress if the GOP Senate blocks it?

For starters, Biden could declare a climate emergency and sign a series of executive orders to achieve 100% clean energy and other objectives. His pen has the power to stop all new fossil fuel extraction and drilling leases and to strengthen automobile efficiency and power plant emission standards.

As a former longtime senator, Biden has a deep understanding of the byzantine ways of the Senate’s process. He will need all of his political skill to wring something good out of this complicated legislative body.

President Biden will have to achieve way more than President Barack Obama did. Obama 2.0 will not be enough. The best climate science says that we have about 10 years left to prevent catastrophic damage. Candidate Biden understood both the urgency and the opportunity in the climate crisis.

It is now up to President Biden to deliver.
