Can a Global Carbon Tax Save the Planet? What would it take for the world to adopt a global carbon tax \u2014 and could such a policy become a meaningful tool for responding to the climate crisis?<\/p>\n\n\n\n

In this episode of Visions of a Better World, Max Tallberg and Astrid Aminoff sit down with Jamie Morgan (Leeds Beckett University) and Heikki Patom\u00e4ki (University of Helsinki), who have collaborated extensively on proposals for a global greenhouse gas tax. The conversation moves from policy mechanics into deeper questions of democratic agency, inequality, and the political imagination needed to confront a planetary-scale crisis.<\/p>\n\n\n\n

The mindset problem before the policy problem<\/h2>\n\n\n\n

Before discussing institutions and taxation, the conversation turned to a more fundamental issue: whether people today feel capable of shaping the future at all.<\/p>\n\n\n\n

Heikki Patom\u00e4ki:<\/p>\n\n\n\n

\u201cWhen you put things like you just did \u2014 the non-linear oscillation and how they amplify each other and how these things are connected, the Antarctic ice and all the rest of it \u2014 you actually have a kind of a very vivid way of portraying how things are interconnected on a planetary scale. And that requires also planetary political imagination as well. I think the global greenhouse gas tax could be kind of a manifestation of that imagination in place.\u201d<\/p>\n\n\n\n

Jamie Morgan:<\/p>\n\n\n\n

\u201cHow do people feel on the average? They feel powerless. And most of the time they feel dread. It\u2019s not fear. It\u2019s dread. It\u2019s this idea that there\u2019s something inevitable that is coming that I have no agency to affect.\u201d<\/p>\n\n\n\n

Morgan suggests that the framing of climate policy itself has contributed to this sense of helplessness:<\/p>\n\n\n\n

\u201cPeople should not be put in the situation where we\u2019re expecting them to afford this. We should be thinking about ways of doing this which make it a community issue, where we are distributing the costs in a realistic manner. But the more we privatize the problem and solutions, the less we think that way. The more we let economists talk about this, the more it becomes an economic problem. But really, this is not an economic problem. Our economies have created it, but it is not an economic problem.\u201d<\/p>\n\n\n\n

Patom\u00e4ki describes climate change primarily as a challenge of institutional and social redesign:<\/p>\n\n\n\n

\u201cIt\u2019s a social redesign problem.\u201d<\/p>\n\n\n\n

He also points to the lack of meaningful democratic structures at the global level:<\/p>\n\n\n\n

\u201cIn the absence of adequate global institutions where some sort of politics, where there\u2019s political space and some democratic politics can take place \u2014 and in the absence of transforming political agency on a world scale \u2014 what we have are these movements and parties and so on that are only within the confines of the national states.\u201d<\/p>\n\n\n\n

Morgan returns to the psychological dimension of agency:<\/p>\n\n\n\n

\u201cYou do not have agency until you realize you have it. You can\u2019t use agency you refuse to accept that you have. So it\u2019s a mindset problem before it\u2019s anything else.\u201d<\/p>\n\n\n\n

And on the economic models still shaping much of climate policy:<\/p>\n\n\n\n

\u201cIf you still look at the main models that are being created \u2014 these integrated assessment models \u2014 what\u2019s the optimal warming they\u2019re estimating? Between 2.7 degrees and 4. That\u2019s what they are saying is optimal based on an economic model. Now, you tell me that that isn\u2019t insane.\u201d<\/p>\n\n\n\n

What if we\u2019d chosen a carbon tax thirty years ago?<\/h2>\n\n\n\n

Max Tallberg: \u201cEarlier in your discussion, you mentioned the previous times when we took the road of emission trading systems. I was wondering \u2014 how could or would the world look today if we had chosen the carbon tax instead of emission trading earlier?\u201d<\/p>\n\n\n\n

Heikki Patom\u00e4ki:<\/p>\n\n\n\n

\u201cThe current system, which is market-based, very much reflects the hegemony of neoliberalism in the world. If something like a global greenhouse gas tax had been established already in the 1990s, it would have indicated a different course of world history, basically toward a more global Keynesian direction.\u201d<\/p>\n\n\n\n

Morgan emphasizes that meaningful policy outcomes depend on broader political and institutional conditions:<\/p>\n\n\n\n

\u201cAt any point in time, there have to be levers to allow you to change the way the world is in order to get the outcomes you would prefer.\u201d<\/p>\n\n\n\n

He also highlights the practical challenge of balancing carbon taxation with growing global energy demand:<\/p>\n\n\n\n

\u201cYou have to decelerate the growth of energy demand in order to allow a disruptive carbon tax to impact in such a way as it can keep pace with changes in energy demand.\u201d<\/p>\n\n\n\n

A coalition of the devastated<\/h2>\n\n\n\n

Astrid Aminoff: \u201cWe have these countries in the Global South that have experienced the worst effects already, and it\u2019s only getting worse for them \u2014 floods, food scarcity, places becoming uninhabitable. Do you see a future where these countries could come together and implement their own type of carbon tax on the Western countries that caused the problem?\u201d<\/p>\n\n\n\n

Jamie Morgan:<\/p>\n\n\n\n

\u201cA coalition of the devastated rather than a coalition of the willing.\u201d<\/p>\n\n\n\n

Heikki Patom\u00e4ki:<\/p>\n\n\n\n

\u201cIt seems to me that the initiative at the moment is not going to come from North America or Europe. Europe is retreating as well.\u201d<\/p>\n\n\n\n

Patom\u00e4ki also points to the importance of large emerging economies such as China and the wider BRICS bloc in any future climate governance framework.<\/p>\n\n\n\n

Where would the money go?<\/strong><\/p>\n\n\n\n

A major theme of the discussion was redistribution and democratic governance.<\/p>\n\n\n\n

Heikki Patom\u00e4ki:<\/p>\n\n\n\n

\u201cThe potential revenues are really huge. If the price is high enough \u2014 like $60 per tonne or even $100 per tonne \u2014 and if the system was comprehensive, including most of the big emitters, part of the revenues must go to the states that are collecting the tax.\u201d<\/p>\n\n\n\n

His proposal also incorporates historical responsibility:<\/p>\n\n\n\n

\u201cThose countries that are historically most responsible for the problem could dedicate 70% or 80% of their revenues to a global fund, whereas the poorest countries that have least to do with producing the problem could keep most of their revenues.\u201d<\/p>\n\n\n\n

Morgan stresses that any carbon tax would need to be integrated carefully into national energy systems:<\/p>\n\n\n\n

\u201cIf you are not going to take energy pricing into account and then you introduce a carbon tax which will effectively make energy more expensive, you are going to cause a huge problem.\u201d<\/p>\n\n\n\n

Global Keynesianism \u2014 and the question of what economies are for<\/h2>\n\n\n\n

Astrid Aminoff: \u201cI thought that you could have the opportunity to explain one of your favourite subjects \u2014 what a global Keynesian approach would be like for future development and economy. And it ties into that, obviously, how degrowth might be a part of that.\u201d<\/p>\n\n\n\n

Heikki Patom\u00e4ki:<\/p>\n\n\n\n

\u201cGlobal Keynesianism is an attempt to think about economic policy and public policy in general in world terms. It means some macroeconomic policy on a global scale, public investments on a global scale, various systems of regulation on a global scale.\u201d<\/p>\n\n\n\n

He describes the project as an effort to globalize some of the functions traditionally associated with democratic welfare states.<\/p>\n\n\n\n

Morgan returns to the urgency of climate realities already set in motion:<\/p>\n\n\n\n

\u201cWe\u2019ve already created some of the future already in climate terms. And yet, at the moment, we\u2019re not really dealing with what it is that we\u2019ve already done.\u201d<\/p>\n\n\n\n

Hope, urgency, and the species-level \u201cwe\u201d<\/strong><\/p>\n\n\n\n

Astrid Aminoff: \u201cIf you have any final thoughts where you consider a future that might not be so bad \u2014 do you have anything you want to leave us with?\u201d<\/p>\n\n\n\n

Heikki Patom\u00e4ki:<\/p>\n\n\n\n

\u201cThere\u2019s plenty of hope also about better futures. This is a kind of a necessary phase that we have to overcome.\u201d<\/p>\n\n\n\n

Jamie Morgan:<\/p>\n\n\n\n

\u201cWe need to always be making the argument that we should be doing more, at the same time as just pushing ourselves in the right direction.\u201d<\/p>\n\n\n\n
