The Future of European Climate Change Policy

In my previous blog post, on January 14th, I offered my personal views regarding “International Climate Change Policy & Action in the Biden Administration.”  Today, I’m pleased to turn to a parallel assessment of future European climate change policy by Ottmar Edenhofer, a greatly-accomplished German economist, admired by academics, as well as leaders in government, industry, and non-governmental organizations.

Professor Edenhofer’s presentation, “The European Green Deal – Reform or Regulatory Tsunami?” and our subsequent discussion is the most recent webinar in our series, Conversations on Climate Change and Energy Policy, sponsored by the Harvard Project on Climate Agreements (HPCA).  As you know, in this webinar series we feature leading authorities on climate change policy, whether from academia, the private sector, NGOs, or government.  A video recording (and transcript) of the entire webinar is available here.

Ottmar Edenhofer is Professor of Economics at the Technical University of Berlin, the Founding Director of the Mercator Research Institute on Global Commons and Climate Change, and Co-Director and Chief Economist of the Potsdam Institute for Climate Impact Research.  He has been a major contributor to scholarship on the economics of energy and climate change, and served as Co-Chair of Working Group III of Fifth Assessment Report of the Intergovernmental Panel on Climate Change, where I had the pleasure of working under his leadership.  He is a key advisor of the German Government, as well as the European Union.  He holds a Ph.D. in economics and a B.A. degree in philosophy (a pairing of degrees which –  I’m delighted to say – he and I share).

In his presentation and the discussion that follows, Ottmar Edenhofer offers a frank assessment of the European Green Deal’s potential to significantly address the impacts of global climate change. 

“It’s a very good time to talk about the European Green Deal because now the prospects that United States and Europe could work closer together on climate change or climate policy and energy policy are very good,” Ottmar notes, referring to the change in U.S. administrations and recent remarks by European Commission President Ursula von der Leyen reaffirming the European Union’s (EU’s) intent to reduce its target for emission reductions from 40 percent to 55 percent by the year 2030 and to achieve net carbon neutrality by the year 2050.

Calling it a “huge task,” Edenhofer outlines the actions that would need to occur to achieve such ambitious goals, including enhanced efforts to decarbonize the power sector, accelerated electrification for end-users, increased investments in bio-energy and semi-synthetic fuels, and advancements in carbon dioxide removal technologies. Using the EU’s climate policy impact assessment as a framework, he walks us through three different policy scenarios, ranging from one that relies heavily on regulation to one structured primarily around carbon pricing.

Characterizing the heavily regulatory approach as a “high-risk scenario,” he instead promotes the idea of an “intermediate step” in a which a mix of policy measures and carbon pricing are deployed to move toward the goal of a 55-percent carbon emissions reduction, and toward a longer-term strategy of using carbon pricing alone as the primary driver in CO2 reduction efforts.

“The crucial question therefore is, how can we design this intermediate step, and this is really the most important debate around this reform proposal,” he says, noting that several issues would need to be addressed.  “The intermediate step has to address the distributional issues and guarantee the stability and manage the political economy challenge between the sectors.”

Professor Edenhofer suggests that the intermediate step that may gain the political support necessary to succeed would be one that would allow for two separate emissions trading systems – one for the energy and industry sector, and the other for transportation and buildings.

“Meanwhile we could define gateways between these two systems. “Creating such gateways might have a two-fold effect – the first one is that market participants already anticipate that there are gateways and they anticipate these enterprise expectations, and this could lead to a convergence of the different prices across the sectors. And secondly, this is a starting point to manage the division of labor among the sectors, and this could be a credible pathway toward a carbon-price scenario when we have one ETS with one credible CO2 price scenario.”

In his presentation, Edenhofer also acknowledges the role that fiscal federalism could play in affecting the future direction of climate policy in Europe. While arguing that carbon pricing could generate roughly 800 billion euros between now and 2050, he notes that the funding base would shrink over time as emissions decrease, and therefore would not serve as a stable revenue source.  He has answers for this challenge as well.

After his presentation, Professor Edenhofer responds to questions from the virtual audience of more than 200 people. One question focuses on the impact of the new Biden-Harris Administration in Washington on global efforts to address climate change.

“The good thing is they are back in the Paris Agreement.  The announcement alone that the U.S. is committed has already helped.”

All of this and much more can be seen and heard in the full webinar here.  I hope you will check it out.

Previous webinars in this series – Conversations on Climate Change and Energy Policy – have featured Meghan O’Sullivan’s thoughts on Geopolitics and Upheaval in Oil Markets, Jake Werksman’s assessment of the European Union’s Green New Deal, Rachel Kyte’s examination of “Using the Pandemic Recovery to Spur the Clean Transition,” Joseph Stiglitz’s reflections on “Carbon Pricing, the COVID-19 Pandemic, and Green Economic Recovery,” Joe Aldy describing “Lessons from Experience for Greening an Economic Stimulus,” and Jason Bordoff commenting on “Prospects for Energy and Climate Change Policy under the New U.S. Administration.”

The next bi-monthly HPCA Conversation on Climate Change and Energy Policy will take place in March.  You can register in advance for that event at the HPCA website.

The IPCC at a Crossroads

Love it or hate it, the Intergovernmental Panel on Climate Change (IPCC) plays a very important role in global climate change policy around the world. This is because its reports enjoy a degree of credibility that renders them influential for public opinion, and – more important – it is because the reports are accepted as the definitive source on all matters climate change by international negotiators working under the United Nations Framework Convention on Climate Change (UNFCCC). In previous essays at this blog, I have written both about problems with the IPCC process (Is the IPCC Government Approval Process Broken?, April 25, 2014) and about its significant merits (Understanding the IPCC: An Important Follow-Up, May 3, 2014; The Final Stage of IPCC AR5 – Last Week’s Outcome in Copenhagen, November 4, 2014).

The IPCC is now at a crossroads. Its Fifth Assessment Report (AR5) is now complete and largely successful (see my previous essays cited above). But, like many large institutions, the IPCC has experienced severe growing pains. Its size has increased to the point that it has become cumbersome, it sometimes fails to address the most important issues, and – most striking of all – it is now at risk of losing the participation of the world’s best scientists, due to the massive burdens that participation entails.

The good news is that this is a moment of considerable opportunity for addressing these and other challenges, because the direction of future assessments is now open for discussion and debate. Indeed, as I write this, the 195 member countries of the IPCC are meeting in plenary in Nairobi, Kenya, to discuss – among other topics –the future of the IPCC.

A Potentially Important Meeting on Another Continent

Just one week before the Kenya IPCC sessions commenced, another, much smaller meeting took place about 4,000 miles northwest of Nairobi – in Berlin, Germany. Twenty-four participants with experience with the IPCC met in Berlin for a three-day workshop on the future of international climate-assessment processes, from February 18th through 20th. The aim of the workshop was to take stock and reflect on lessons learned in past assessments – including those of the IPCC – in order to identify options for improving future assessment processes.

Participants included social scientists who contributed in various capacities to AR5 and earlier IPCC assessments, users of IPCC reports (from national governments and intergovernmental organizations), and representatives of other stakeholder groups. Participants came from both developed and developing countries, and discussions were held under Chatham House rules, with no public attribution of any comments to individuals.

The workshop (titled “Assessment and Communication of the Social Science of Climate Change: Bridging Research and Policy”) was co-organized by four academic and research organizations based in Europe and the United States: Fondazione Eni Enrico Mattei (FEEM, Italy), the Harvard Project on Climate Agreements (USA), the Mercator Research Institute on Global Commons and Climate Change (MCC, Germany), and the Stanford Environmental and Energy Policy Analysis Center (USA).  FEEM, the Mercator Institute, and the Alfred P. Sloan Foundation provided financial support for the workshop.

Possible Ways Forward for the IPCC

As I noted above, now is a moment of considerable opportunity, because the future of the IPCC is open for discussion and debate, including at the meeting taking place this week in Nairobi. In this context, two of my co-organizers – Carlo Carraro of FEEM and Charles Kolstad of Stanford – and I have written a brief memorandum, based on our reflections on the Berlin workshop discussion. We describe a set of specific challenges and opportunities facing the IPCC, and provide options for improving the IPCC’s process of assessing scientific research on climate change. The complete memorandum is available here for your reading, and so I won’t attempt to summarize the highlights in this blog post, but simply note that our analysis focuses on five areas:

  • Improving integration and coordination across IPCC working groups, and enhancing the interface between scientists and governments;
  • Enhancing the interface between the IPCC and various social scientific disciplines and communities;
  • Increasing efforts – in innovative ways – to facilitate contributions of expertise from developing countries;
  • Increasing the efficiency of IPCC operations and ensuring the scientific integrity of its work products through targeted organizational improvements; and
  • Strengthening outreach and communications.

I should also note that Carraro served as Vice-Chair, and Kolstad and I served as Coordinating Lead Authors, all of Working Group III of the IPCC’s Fifth Assessment Report, but our organizing of the workshop and our authoring of this new memorandum were carried out in our roles as researchers, and completely independently of our former official capacities with the IPCC.

The Path Ahead

The memorandum is only the first of several products that will be forthcoming from this initiative. Over the coming months, we will produce a comprehensive report from the workshop (in time for the IPCC’s next meeting in October of this year, as well as the subsequent UNFCCC meeting in Paris in December). When that report is available, I will be pleased to bring it to the attention of readers of this blog.
