Carbon pricing works, and this proves it Paul Burke Tue, 09/01/2020 – 00:45 Putting a price on carbon should reduce emissions, because it makes dirty production processes more expensive than clean ones, right? That’s the economic theory. Stated baldly, it’s obvious; however, there is perhaps a tiny chance that what happens in practice might be something else. In a newly published paper , we set out the results of the largest study of what happens to emissions from fuel combustion when they attract a charge. We analyzed data for 142 countries over more than two decades, 43 of which had a carbon price of some form by the end of the study period. The results show that countries with carbon prices on average have annual carbon dioxide emissions growth rates that are about two percentage points lower than countries without a carbon price, after taking many other factors into account. By way of context, the average annual emissions growth rate for the 142 countries was about 2 percent per year. This size of effect adds up to very large differences over time. It is often enough to make the difference between a country having a rising or a declining emissions trajectory. Emissions tend to fall in countries with carbon prices A quick look at the data gives a first clue. The figure below shows countries that had a carbon price in 2007 as a black triangle and countries that did not as a green circle. On average, carbon dioxide emissions fell by 2 percent per year from 2007 to 2017 in countries with a carbon price in 2007 and increased by 3 percent per year in the others. The difference between an increase of 3 percent per year and a decrease of 2 percent per year is five percentage points. Our study finds that about two percentage points of that are due to the carbon price, with the remainder due to other factors. The higher the price, the greater the benefit The challenge was pinning down the extent to which the change was due to the implementation of a carbon price and the extent to which it was due to a raft of other things happening at the same time, including improving technologies, population and economic growth, economic shocks, measures to support renewables and differences in fuel tax rates. We controlled for a long list of other factors, including the use of other policy instruments. It would be reasonable to expect a higher carbon price to have bigger effects, and this is indeed what we found. On average, an extra euro per tonne of carbon dioxide price is associated with a lowering in the annual emissions growth rate of about 0.3 percentage points in the sectors it covers. Avoid the politics if possible The message to governments is that carbon pricing almost certainly works, and typically, to great effect. While a well-designed approach to reducing emissions would include other complementary policies , such as regulations in some sectors and support for low-carbon research and development, carbon pricing ideally should be the centerpiece of the effort. Unfortunately, the politics of carbon pricing have been highly poisoned in Australia, despite its popularity in a number of countries with conservative governments, including Britain and Germany. Even Australia’s Labor opposition seems to have given up. Nevertheless, it should be remembered that Australia’s two-year experiment with carbon pricing delivered emissions reductions as the economy grew. It was working as designed. Groups such as the Business Council of Australia that welcomed the abolition of the carbon price back in 2014 are calling for an effective climate policy with a price signal at its heart. Carbon pricing elsewhere The results of our study are highly relevant to many governments, especially those in industrializing and developing countries, that are weighing their options. The world’s top economics organizations, including the International Monetary Fund, the World Bank and the Organization for Economic Co-operation and Development, continue to call for expanded use of carbon pricing. If countries are keen on a low-carbon development model, the evidence suggests that putting an appropriate price on carbon is a very effective way of achieving it.

This moment: An open letter to the GreenBiz community

Comments Off on This moment: An open letter to the GreenBiz community

This moment: An open letter to the GreenBiz community Joel Makower Tue, 06/02/2020 – 02:11 In the wee hours of Nov. 9, 2016, shortly after Donald Trump was declared the 45th president of the United States, I sat down and penned a note to the GreenBiz community. A lot of us were shocked, confused, depressed and angry that this vulgar man, who saw climate change as a hoax and “beautiful clean coal” as our savior, would be setting the national agenda at such a critical time. It was “a stunning and devastating indictment of decency, fairness and inclusion,” I wrote that morning. And: It will be critically important, for both our individual sanity and our collective future, that we stay the course, double down, make every program, project, partnership and product count. That was then. The past few days, in the wake of the national upheaval over the death of yet another black man at the hands of yet another white police officer, have been similarly filled with angst and anger within the sustainability community. “What do we do?” we’ve asked one another. Should we simply stay the course, doubling down on our work on climate and the clean economy, which is growing more urgent by the day? Or do we stop, take stock and rethink what we do? Today, I’m not sure that staying the course is, in and of itself, what’s needed. It may be time for a radical rethink: Given all that’s changing, what does the world need of us now? Whether you come from privilege or poverty, whether your education comes from the best schools or the streets, whatever your politics or identity, this is a brutally tough moment. The coronavirus and economic crash already had laid bare the inequity and disparity among the classes and races: those who have a job and those who don’t; those who are able to earn a living at home versus those who must risk going to an employer’s workplace during a pandemic; those who are able to afford food, shelter and healthcare, even amid economic upheaval, and those who can’t; those who feel comfortable walking or driving or just being outside their home, and those who fear that any moment could lead to their becoming the next George Floyd, Eric Garner, Tamir Rice or Sandra Bland. Now, all of those inequities and disparities have been cast into the open. To the extent they existed in the shadows — festering societal problems to which those with power and privilege largely threw up their hands — they are now center stage. To the extent these problems could be ignored — that one could live life without having to reckon with race, poverty and inequality — they have been thrust onto our individual and collective doorsteps. To the extent they were topics relegated to hushed, private conversations — well, those conversations are full-throated, 24/7 and inescapable. To the extent these problems could be ignored — that one could live life without having to reckon with race, poverty and inequality — they have been thrust onto our individual and collective doorsteps. The calamities of 2020 — the physical, economic, social and psychological crises we’d already been confronting these past few months — have contributed to this raw moment, the culmination of centuries of systemic oppression and institutionalized racism. Words of comfort, of healing and hope, aren’t cutting it, and they shouldn’t. For those of us working in sustainability, it raises some fundamental questions. Among them: What led you to this work in the first place? Was it to protect the unprotected? To ensure the well-being of future generations? To engender community resilience? To create solutions to big, seemingly intractable problems? Or maybe, simply, “to make the world a better place”? If so, then this is the moment to live up to those lofty goals — fully and, most likely, uncomfortably. That means having difficult conversations with family, colleagues, friends and peers. It means recognizing — really, truly recognizing, not just mouthing the words — that nothing is sustainable if people are in pain. It matters little how much renewable energy is generated, how many circular supply chains are created, how much organic or regenerative food is produced if our fellow citizens are being exploited, discriminated against, threatened and worse. This is what ‘sustainability’ should be about — the security and well-being of all species. This is what “sustainability” should be about — the security and well-being of all species, including humans — and it no doubt will provoke nodding heads among many of you. But nodding heads aren’t enough. They never were and certainly aren’t now. This is a moment for the private sector to step up. Not just in helping to calm and heal, although that will be a critical task in the coming days and weeks, but also to lobby for justice: economic justice, racial justice, criminal justice, climate justice. And to deeply understand what these terms even mean, and how they relate to creating the societal value that is the beating heart of business.  This is a seminal moment that is testing all of us — those in sustainability, certainly, along with most everyone else. And as we work on or support societal solutions — and countless ideas are likely to come out of this, from every conceivable source — it’s important to ask some simple but profound questions: Who’s setting the rules? Who’s calling the shots? Who’s being heard? Who’s left out? Who’s benefiting from the status quo and from the proposed solutions? Does it empower the marginalized or merely placate the restless? These are the kinds of questions that have been woefully absent in the past. And we are living with the result. If we are to change the course, not simply aim to get back to some elusive “normal,” these questions will need to be asked and answered. Failure to do that will lead us right back to where we are. I’d like to end on a positive, hopeful note, much as I tried to do back in November 2016. But hope and positivity are in short supply right now. So I’ll just say this: Don’t underestimate your power in this moment. You may not feel powerful, particularly in light of the deafening voices screaming in the streets and on our screens. But there is power in us all: to care for those around us, to contribute time and resources at the community and national levels, to take the time to truly comprehend the issues before us and to understand that silence is complicity. Pull Quote To the extent these problems could be ignored — that one could live life without having to reckon with race, poverty and inequality — they have been thrust onto our individual and collective doorsteps. This is what ‘sustainability’ should be about — the security and well-being of all species.
