Two facts are pretty much all you need to know to put the climate crisis at the top of your voting agenda. One: the ecological emergency is we face as a species. And two: getting our planet back on track for a survivable future

It’s really as simple as that. 

Since climate change disproportionately affects people who are shut out of traditional politics, a shift towards could be the best chance to win back our futures. To transcend politics as usual and citizens of the world’s democracies will need to insist their voices are heard.

That’s already happening. Recent polls show that in the US and around the world, climate change It has played key roles in recent elections in and For voters considering candidates to oust Donald Trump, the current US president,

In 2020, of course, the US elections will dominate the global news cycle, but there are around the world that will set the near-term trajectories of dozens of democracies. Every one of these elections are vital. In every election, a climate champion needs to be on the ballot, and they need to win.

All of these elections have the same basic purpose during a climate emergency: elect the person who has the best chance of enacting an agenda that brings us closer to a thriving world for all living things. The answer might not be immediately obvious, which is why open debate and freedom from the excessive influence of and are so important. 

Four questions to figure out who your climate candidate should be

The way I see it, there are four basic criteria that make a good climate candidate, based on what the science says is necessary and We have much of the technology we need to work towards a zero-carbon world today. What we need is better leadership and a stronger movement. Here’s how to figure out who your climate candidate is:

  1. Do they understand what scientists say
  2. Do they plan to implement inclusive changes that address the root of the climate problem with social justice for everyone?
  3. Do they have an inspiring vision that could actually build a movement and be implemented?
  4. What are the financial tradeoffs in paying for these policies?

Basically, these criteria boil down to:

  • Is their plan enough?
  • Does their plan put people at its centre?
  • Does their plan stand a chance of actually becoming law?

In wealthy countries, “how do we pay for it?" has become code for austerity advocates and climate change deniers to dismantle social policy such as health care and pensions. In the frontline countries of the climate emergency,

Current estimates show That is The investment would And since electricity production makes up only a comprehensive climate plan needs to be much bigger than that.

It is impossible to put all our money in renewables at once, and to be on track to avoid 1.5C. To do that, the minimum required investment would be about $36.5tn for renewable energy this decade globally, multiplied by four (to decarbonise 75% of the economy outside of electricity production) – roughly or $15tn per year,

Since rich countries bear more responsibility, the fairest climate policy would make historically large emitters pay more. So look for candidates who have a plan to devote more than 20% of their national GDP in public and private spending to climate action. In the US, that benchmark is about $4tn per year.

Biden’s plan doesn’t go far enough

In the US, these criteria should automatically eliminate members of the Republican party for consideration because until recently, they didn’t even have a climate plan. In the past few days, details have begun to emerge of but with no firm targets to actually reduce emissions. That’s disqualifying.

That leaves the Democrats, who are about to begin with the first votes due in Iowa on 3 February. Of the three leading candidates – Joe Biden, Bernie Sanders, and Elizabeth Warren – there are some stark differences.

The three leading Democratic candidates all call climate change an ‘existential threat’. But when you look at their actual plans, there are major differences.

The three leading candidates all call climate change an "existential threat" and acknowledge that bold action is necessary. But when you look at the candidates’ actual plans, there are major differences in how those visions would be implemented.

is the least ambitious of the top three Democrats, planning to earmark $5tn of public and private spending over the next 10 years, mostly for renewable energy research and infrastructure. Worse, his goal of net zero emissions in the US by 2050 is only in line with if it’s achieved on a global scale, but far too late for the country that has contributed the most to causing this planetary emergency. It’s not clear that Biden’s plans would be a significant improvement on former US president Barack Obama’s climate policy.

The most ambitious US climate policy ever proposed

In contrast, either Sanders or Warren would be the best president we’ve ever had on this issue. 

In terms of ambition, Sanders is the top choice. of which would invest $16.3tn in public money alone over 15 years, is by any major candidate for president, and that’s by design: big changes can come faster by strategically rallying people who have been excluded from politics for decades.

Either Sanders or Warren would be the best president we’ve ever had on climate change. 

A Sanders-proposed federal jobs guarantee would put people to work building not only zero-carbon infrastructure but also a culture of care and respect for human rights and environmental protection. Using the level of public investment as a benchmark, Sanders’s plan is at least six times more ambitious than Biden’s: more than $1tn a year, compared to $170bn. Assuming a four-to-one ratio of private-to-public money, as Biden’s plan does, Sanders’s plan would devote a little more than 20% of the US economy toward fighting the climate emergency.

Among climate wonks, Sanders’s consistent rejection of nuclear energy but his emissions reduction plans go beyond even what Paris requires. Sanders plans to rapidly and completely decarbonise the US power and transportations sectors – cutting while guaranteeing enough international support to help developing countries cut their emissions by 36% in the same timeframe. 

In times like ours, being realistic is the same as being radical

There’s also a persuasive case for Warren, who has made a strong name for herself as a champion of comprehensive environmental policy. She has released comprising a total of $10.7tn in public and private spending over 10 years on everything from transforming agricultural towns to cancelling hurricane-related debt in Puerto Rico to a “Blue New Deal” plan for oceans.

Her plans including 100% carbon neutral electricity and zero-carbon standards for all new buildings and vehicles by the end of the decade. She has said her first task is However, on Indigenous issues, the effectiveness of capitalism, and have undermined her claims of being a champion of social justice. And when using public funding as a measure, Warren’s climate plans are less than half as ambitious as Sanders’s. 

In times like ours, being realistic is the same as being radical. Although climate change is the biggest existential threat we’ve ever faced, and any effective climate leader must learn quickly from people outside of traditional politics. Sanders understands the roots of the climate crisis are in how we treat each other, not just the kinds of fuel we use to create electricity. When you see the world this way, a climate plan focused on tackling social inequality provides the most realistic path toward a liveable future that works for everyone.

What’s absolutely clear is that even with Sanders as the next president of the United States, winning elections is not enough in a climate emergency. While climate scientists are finding new ways to scare us daily about the fate of the planet, we need to have leaders who consistently respond in a way that’s necessary. We need to build a movement to push our politicians to outline revolutionary visions of change.
