California’s Crude Oil Production and its Climate Change Policies

California is among the most aggressive jurisdictions in the world in its pursuit of public policies to reduce its emissions of greenhouse gases (GHGs), linked with climate change. At a time when the Trump administration in Washington is working to reverse the Obama administration’s climate policy achievements, California and other sub-national entities are taking the lead in the development and implementation of meaningful domestic policies to mitigate the impact of human activity on the climate.

At the same time, California is a producer of crude oil.  Is this inconsistent, or even counter-productive?  In a recent report, advocates have criticized Governor Jerry Brown, and proposed a ban on crude oil production within the State, in furtherance of California’s climate policies.  The thinking goes, crude oil production leads to environmental impacts, so how can it be allowed?

The logic is flawed, and the prohibition – if adopted – would impose tremendous costs on the State with little or no environmental benefit.  As California has developed its climate policies, the need to balance the benefits of these policies with their economic and human consequences has always been a challenging issue.  Achieving aggressive climate goals will not be cheap, so designing sensible, effective policies is critical.  Simply adopting any and all restrictions that might achieve some emission reductions would unnecessarily raise the human cost of limiting GHG emissions.  This is no doubt obvious to some readers of this blog, but for others, let me explain.

At its heart, the climate problem arises because of CO2 emissions associated with the use of energy and related services.  We heat our homes in the winter and cool them in the summer using electricity and natural gas.  We use gasoline to get to work and take vacations.  As each country or state – including California – tries to reduce its GHG emissions, the policies and regulations adopted to achieve this end nearly always target the activities that lead to GHG emissions – the generation of electricity, the use of transportation, and the heating of living spaces.

The proposed ban on crude oil extraction would flip this on its head, focusing instead on the supply of a fossil fuel.  But the simple reality is that the sources of fossil fuel supply are so ubiquitous that crude oil from other regions of the world will replace supplies from California, if California chose not to supply its own on-going needs.  Oil and gas used to heat homes and to power vehicles comes not only from California, but from most every region of the globe.  Many of these regions have expanding supplies of crude oil due to technological improvements, including the Bakken shale of North Dakota, and vast supplies available with relatively little effort, such as in the Middle East.

Advocates claim that reduction of California crude oil production would reduce global consumption of crude – a claim of questionable validity.  But that is not even the right question.  There are many things that can be done to reduce GHG emissions, and a sensible, affordable, and sustainable policy will be one that achieves reductions at the lowest cost.  Even if restricting California’s oil production might reduce global crude consumption, California would certainly bear all of the economic consequences of this policy, as the state would then rely solely on crude oil imports.

In fact, a restriction on California’s crude production is unlikely to reduce GHG emissions within California. The State’s total GHG emissions are limited by the cap of California’s GHG cap-and-trade system.  The most a restriction on California’s crude production can do is to increase costs, while achieving little or no incremental improvement in GHG emissions.

Moreover, supply-side restrictions can limit technological progress that can have very positive economic and environmental consequences.  The same advocates oppose shale “fracking,” but the innovative combination of hydraulic fracturing and horizontal drilling has led both to tremendous economic benefits by expanding supplies of low-cost domestic energy and reducing energy imports, and to environmental benefits by allowing lower-carbon natural gas to displace higher-carbon coal in the generation of electricity across the United States.

By focusing on policies aimed at achieving the appropriate policy goal of reducing GHG emissions – rather than trying to choose winners and losers among technologies and energy sources used to achieve those goals – California can achieve its climate policy goals in ways that are environmentally effective, economically sensible, and ultimately sustainable.  In my view, Governor Brown merits compliments rather than criticism for California’s progressive environmental and energy policies.

========================================================

In the past, I have periodically advised the Western States Petroleum Association (WSPA), although on a very different issue, namely the design of California’s CO2 cap-and-trade system.  That was about two years ago, and neither WSPA nor any of its member companies are aware of my writing this essay.  As always in this blog, I am expressing my personal views, and not speaking on behalf of any of the institutions, organizations, or firms with which I am or have been associated.

What Should We Make of China’s Announcement of a National CO2 Trading System?

On December 19, 2017, the government of China announced that it is commencing development of a nationwide CO2 trading system, that when launched will become the world’s largest carbon trading system, annually covering about 3.5 billion tons of CO2 emissions in China’s electric power sector.  That approaches twice the size of what is currently the world’s largest carbon trading system, the European Union Emissions Trading System, which accounts for about 2 billion tons per year, and is nearly nine times the size of the largest U.S. system, the California AB-32 cap-and-trade system, which covers about 400 million tons of annual emissions.

The ultimate purpose of the newly announced Chinese trading system is to help the country meets its emissions and renewable energy targets which are part of its Nationally Determined Contribution under the Paris Agreement, in particular, peaking its CO2 emissions by 2030, and achieving 20% of the country’s energy supply from renewables.  Note that coal currently accounts for 65% of China’s electricity generation.  Wind and solar capacity have been growing rapidly, but still account for only 4% and 1% of generation, respectively.

The Chinese carbon market will double the share of global CO2 emissions covered by worldwide carbon-pricing systems to almost 25 percent.  For this and other reasons, the December announcement was greeted with excited praise from climate activists (but simultaneously with disregard and skepticism from conservative opponents of climate action).  The most reasonable assessment, however, is between those two extremes, as I explain in this essay.  That said, the December announcement by China of its plan to develop and launch a nationwide CO2 trading system is an important landmark on the long road to addressing the threat of global climate change.

Some Brief History for Context

In 2011, China’s 12th Five-Year Plan (2011-2015) first included a statement about the government’s intention to develop – gradually – a nationwide carbon market.  Subsequently, in 2013 and 2014, seven pilot emissions trading programs were launched in the cities of Beijing, Chongqing, Shanghai, Shenzhen, and Tianjin, plus two provincial systems in Guangdong and Hubei.  In total, these covered some 3,000 sources, with total annual CO2 emissions of 1.4 billion tons.  The designs of the systems were intentionally varied, to facilitate learning, and allowance prices ranged from $3 to $10 per ton of CO2.

Then, in the lead-up to the Paris climate negotiations, on September 25, 2015, President Xi Jinping met at the White House with U.S. President Barack Obama, and announced that China would launch its nationwide CO2 trading system in 2017, presumably covering electricity, iron and steel, chemicals, cement, and paper production.

The announcement last month was the culmination of this brief history, as China seeks to move ahead with its “pledges” under the Paris Agreement, at the same time as the Trump administration in the United States intends to withdraw altogether from the Agreement (in November, 2020, the soonest that such withdrawal can take place under the rules of the Agreement).

What’s Known about the Chinese Carbon Trading System

China’s December announcement that it is commencing development of a nationwide CO2 trading system, beginning with the electric power sector only, provided few detailsApparently, the system is intended to eventually include electricity, building materials, iron and steel, non-ferrous metal processing, petroleum refining, chemicals, pulp and paper, and aviation, but will start with the electricity sector alone.  Like most operating systems in the world, it will regulate only CO2, not other greenhouse gases (GHGs), which in China’s case means potentially addressing more than 80% of its total GHG emissions.

The system will not be a cap-and-trade system per se (unlike the CO2 trading systems in Europe and California, for example), because there will not be an administratively set mass-based cap of some quantity of emissions.  Rather, the trading system will be rate-based, meaning that it will be in terms of emissions per unit of electricity output.  This is also called a tradable performance standard, whereby the government sets a performance standard (a benchmark emissions rate per unit of output), sources receive permits (allowances) based on their electricity output and their benchmark, and sources are allowed to trade.  Such tradable performance standards have been used previously in a variety of contexts, including the U.S. EPA leaded gasoline phasedown in the 1990s, U.S. Corporate Average Fuel Economy (CAFE) standards to regulate motor-vehicle fuel efficiency, the Obama Administration’s Renewable Fuel Standard, and California’s Low Carbon Fuel Standard.

One objective of using this approach is to insulate – or at least cushion – the (electricity) sector and the larger economy from “carbon market shock.”  By regulating the emissions rate (per unit of product output), rather than emissions per se, the rate-based approach may help mitigate the political worry about constraining economic growth, but does so by essentially rewarding (subsidizing) higher levels of output.  This relative inefficiency of China’s rate-based system, compared with a mass-based cap-and-trade approach is highlighted in a new paper by Lawrence Goulder (Stanford University) and Richard Morgenstern (Resources for the Future) and one by William Pizer (Duke University)and Xiliang Zhang (Tsinghua University).  (There is a parallel impact and concern – in cap-and-trade systems – with an output-based updating allocation, which can address competitiveness impacts but also introduces inefficiencies by subsidizing dirty production.  This mechanism – which affects only energy-intensive and trade-exposed industries – was proposed in the Waxman-Markey climate legislation and is employed in California’s system.)

The rate-based approach is intended to have a smaller impact on marginal production costs than the mass-based cap-and-trade approach, and thereby is likely to have a smaller impact on the price of products (whether electricity or manufactured goods).  This is the motivation for using this approach in an output-based updating allocation, as described above, and it carries with it the parallel disadvantage of insulating consumers from (some of) the social costs of their consumption decisions.  The problem is exacerbated in the case of China’s evolving system because the performance standards (emission benchmarks) are set not only by sector, but by various categories of electricity production within the sector.  As some categories are, in effect, subsidized by other categories, the cost-effectiveness of the overall system declines.  There is a lack of incentive for the carbon market to move energy consumption from coal to natural gas, for example, because of the multi-benchmark approach.

Finally, it appears that allowances will be allocated without charge, at least in the early stages of the program, which has been typical of emissions trading systems in other parts of the world, and may lessen political resistance while also sacrificing potential efficiency gains associated with auctioning allowances and recycling revenues.

What’s Unknown about the Chinese Carbon Trading System

Among the key design elements that are unknown as of now (at least to me) are the following:

(1)        What will the total allocation of allowances initially be and how will it change (presumably decrease) over time?  Apparently the overall “cap” will be set by adding up the expected emissions of compliance entities, based on their historical emissions.  Then, allocations will be reduced, presumably based on technology performance benchmarks.

(2)        When will trading commence?

(3)        What share of allowances will be distributed for free, and how many – if any – will be auctioned (and how will any auctions operate)?

(4)        What provisions will there be for monitoring and enforcement, and will there be fines or other penalties for non-compliance?

(5)        How will the system interact with other Chinese climate policies?  This is an important question, because so-called “complementary policies” that seek to regulate sources under the cap of a cap-and-trade system can lead to perverse outcomes, as in the European Union and California.

(6)        What is the time-path for expanding the scope of the system to include more sectors, and what sectors will be added?

(7)        When and how, if at all, will China seek to link its system with carbon-pricing and other climate policies in other parts of the world?

Given all of these open questions plus the limited sectoral scope of the announced system, it is reasonable to ask:  what should we make of all this?

How Significant was the Chinese Announcement?

The announcement, despite all the caveats, was a significant step along the road of climate change policy developments, because the Chinese system will eventually be very important, because of its magnitude and because of the importance of China in CO2 emissions and climate change policy.  However, the announcement was not a launch per se, but a statement about a forthcoming launch.

More broadly, the announcement and the eventual launch of the system will have significant effects on other governments around the world – regional, national, and sub-national.  Some will be encouraged to launch or maintain their own carbon trading systems, and to increase the ambition of their systems.  Why do I say this?

A frequently stated fear of adopting climate policies, including carbon pricing, is the competitiveness effects of those policies, due to emission, economic, and employment leakage.  This is more a political issue than a real economic one, but it is nevertheless important.  Since the greatest fear in this realm is that domestic factories will relocate to China, that concern will be greatly reduced – or at least it should be – when and if China has put in place a serious climate policy, whether through carbon markets or otherwise.

China is moving slowly and cautiously, which is wise.  Not long ago, they were considering launching a system that would initially cover 7,000 companies in several sectors, but the 2017 announcement is of a system that covers 1,700 companies in the electricity sector alone.  Of course, it is still important, given that the electricity sector (with its large coal and natural gas plants) accounts for fully a third of China’s CO2 emissions.

During the next two years, the Chinese government – apparently through its National Development and Reform Commission (NDRC), which will administer the trading system – will begin by developing systems for data reporting, registration, & trading – gathering and verifying plant-level emissions data.  This will facilitate the establishment of baselines for allocations of allowances.  Beyond this, a wide range of rules will need to be established.  Following some tests, the actual spot market may launch in 2020 (the same year the Paris Climate Agreement essentially replaces the Kyoto Protocol).

The Path Ahead

As inevitably seems to be the case, the best assessment of this new policy lies somewhere between the extremes.  The December announcement by China was neither as exciting as some of the applause from climate activists might suggest, nor was the announcement as meaningless as conservatives have claimed.

Rather, cautious optimism seems to be in order.  China is serious about climate change, and is thinking long-term.  The country appears to be methodically working to develop a meaningful carbon trading system.  What is important now is developing a robust system that can be effective, expanded in scope, and gradually made more stringent.  Among the greatest challenges will be achieving the cooperation of the provincial governments, not to mention the compliance of the regulated entities.

Development of the system has begun, with the real launch of trading likely to take place in 2020, which is a key year for Chinese climate policy for other reasons, as well.  In that year, China will release its next Five-Year Plan, and it will submit its updated Nationally Determined Contribution to the UNFCCC under the Paris Agreement.  What will the United States be doing that year?  Not much, just electing a President!

Linking Heterogeneous Climate Policies (and Activities at COP-23 in Bonn)

It’s well known that the Paris Agreement has achieved broad participation by countries accounting for some 97% of global GHG emissions (in contrast to the 14% of global emissions associated with countries taking on responsibilities under the current commitment period of the Kyoto Protocol).  That is a very important accomplishment, but as negotiations begin to elaborate key details of the Agreement (as they will in Bonn in November), a critical question is how to create incentives for countries to increase ambition over time. The ability to link different climate policies, such that emission reductions undertaken in one jurisdiction can be counted toward the mitigation commitments of another jurisdiction, may help Parties increase ambition over time.  A new paper from the Harvard Project on Climate Agreements by Michael Mehling of MIT, Gilbert Metcalf of Tufts University, and myself explores options and challenges for facilitating such linkages in light of the considerable heterogeneity that is likely to characterize regional, national, and sub-national efforts to address climate change.  The full paper is available for downloading, as is a two-page summary.

We will be presenting our results on November 13th and 14th in Bonn at the Twenty-Third Conference of the Parties (COP-23) of the United Nations Framework Convention on Climate Change.  At the end of this blog essay, I offer some details about these and other forthcoming activities of the Harvard Project on Climate Agreements at COP-23 in Bonn.

Background

Linkage is important, in part, because it can reduce the costs of achieving a given emissions-reduction objective. Lower costs, in turn, may make it politically feasible to embrace more ambitious objectives. In a world where the marginal cost of abatement – that is, the cost to reduce an additional ton of emissions – varies widely, linkage improves overall cost-effectiveness by allowing jurisdictions with relatively higher abatement costs to finance reductions from jurisdictions with relatively lower costs. In effect, linkage drives participating jurisdictions toward a common cost of carbon, equalizing the marginal cost of abatement and producing a more efficient distribution of abatement activities. These benefits are potentially significant: The World Bank has estimated that international linkage could reduce the cost of achieving the emissions reductions specified in the initial set of NDCs submitted under the Paris Agreement 32% by 2030 and 54% by 2050.

Article 6 of the Paris Agreement provides a foundation for linkage by recognizing that Parties to the Agreement may “choose to pursue voluntary cooperation in the implementation of their” NDCs through “the use of internationally transferred mitigation outcomes” (ITMOs). In contrast to the Kyoto Protocol (which likewise included provisions for international cooperation), the voluntary and flexible architecture of the Paris Agreement allows for wide variation, not only in the types of climate policies countries choose to implement, but in the form and stringency of the abatement targets they adopt.

Heterogeneous Linkage

Linkage is relatively straightforward when the policies involved are similar. However, linkage is possible even when this is not the case: for example, when one jurisdiction is using a cap-and-trade system to reduce emissions while another jurisdiction is relying on carbon taxes. There are several potential sources of heterogeneity: type of policy instrument used (for example, taxes vs. cap-and-trade vs. performance or technology standard); level of government jurisdiction involved (for example, regional, national, or sub-national); status under the Paris Agreement (that is, whether or not the jurisdiction is a Party to the Agreement – or within a Party); nature of the policy target (for examle, absolute mass-based emissions vs. emissions intensity vs. change relative to business-as-usual); and operational details of the country’s NDC, including type of mitigation target, choice of target and reference years, and sectors and greenhouse gases covered.

Analyzing Potential Linkages (Consistent with the Paris Agreement)

The full paper examines five specific cases of linkage, with various combinations of features, to identify which types of linkage are feasible, which are most promising, and what accounting mechanisms are needed to make their operation consistent with the Paris Agreement.  Each of the cases maps to a real-world example.

Most forms of heterogeneity – including with respect to policy instruments, jurisdictions, and targets – do not present insurmountable obstacles to linkage. However, some of these characteristics present challenges and call for specific accounting guidance if linkage is to include the use of ITMOs under the Paris Agreement. In particular, robust accounting methods will be needed to prevent double-counting of GHG reductions, to ensure that the timing (vintage) of claimed reductions and of respective ITMO transfers is correctly accounted for, and to ensure that participating countries make appropriate adjustments for emissions or reductions covered by their NDCs when using ITMOs. Additional issues under Article 6 include how to quantify ITMOs and how to account for heterogeneous base years, as well as different vintages of targets and outcomes.

Issues for the Climate Negotiators

Broader questions that bear on the opportunities for linkage under Article 6.2 include the nature of NDC targets and whether these are to be treated as strict numerical targets that need to be precisely achieved; the nature and scope of ITMOs, which have yet to be defined, let alone fully described, under the Paris Agreement; and finally, whether transfers to or from non-Parties to the Agreement (or sub-national jurisdictions within non-Parties) are possible, and if so, how they should be accounted for. Parties have differing views, however, on whether the guidance on Article 6.2 should extend to such issues.

Clear and consistent guidance for accounting of emissions transfers under Article 6 can contribute to greater certainty and predictability for Parties engaged in voluntary cooperation, thereby facilitating expanded use of linkage. At the same time, too much guidance, particularly if it includes restrictive quality or ambition requirements, might impede linkage and dampen incentives for cooperation. Given their limited mandate, Parties should exercise caution when developing guidance under Article 6.2 that goes beyond key accounting issues. This does not mean that concerns about ambition and environmental integrity should be neglected. However, if the combination of a set of common accounting rules and an absence of restrictive criteria and conditions can accelerate linkage and allow for broader and deeper policy cooperation, it can also increase the potential for Parties to scale up the ambition of their NDCs. And that may ultimately foster stronger engagement between Parties (and non-Parties), as well as with regional and sub-national jurisdictions.

Abstract:

The Paris Agreement has achieved one of two key necessary conditions for ultimate success — a broad base of participation among the countries of the world. But another key necessary condition has yet to be achieved — adequate collective ambition of the individual nationally determined contributions (NDCs). How can climate negotiators provide a structure that provides incentives to increase ambition over time? One part of the answer can be facilitating international linkage of regional, national, and sub-national policies. A central challenge is how to accomplish this in the context of the great heterogeneity that characterizes climate policies, along several dimensions, in the context of Paris-Agreement NDCs. Panelists will review the status of linkage in the world, the evolution of Article 6, and the relationship between the two.

Abstract:

The Paris Agreement has achieved one of two key necessary conditions for ultimate success — a broad base of participation among the countries of the world. But another key necessary condition has yet to be achieved — adequate collective ambition of the individual nationally determined contributions. This panel will consider how this issue might be addressed by international linkage of regional, national, and sub-national policies — that is, formal recognition of emission reductions undertaken in another jurisdiction for the purpose of meeting a Party’s own mitigation objectives. A central challenge is how to facilitate such linkage in the context of the very great heterogeneity that characterizes Nationally Determined Contributions along several dimensions. We consider such heterogeneity among policies, and identify which linkages of various combinations of characteristics are feasible; of these, which are most promising; and what accounting mechanisms would make the operation of respective linkages consistent with the Paris Agreement.
