Abstract:
State-owned enterprises (SOEs) play a major role in the production of goods and services across many of the world’s largest economies, particularly in electricity generation, oil and gas, and heavy industry. SOEs (defined in this report as companies for which 50 percent or more of voting shares are held by a government) are also major sources of greenhouse gas emissions. The governments that control these SOEs are also signatories to the Paris Agreement on climate change. State ownership provides these governments with a major direct point of control over the climate and energy outcomes of these companies, both in terms of reducing emissions and directing future investment into low-carbon technologies and infrastructure. Improving the measurement of SOEs’ contribution to both national and global-level emissions provides important information to help understand to what extent SOEs should be targeted and to design strategies to maximize their potential role in the broader energy transition. This report provides an accounting of direct emissions associated with SOEs globally. It is challenging to comprehensively identify every SOE, as the total is estimated at well over 100,000. In addition, most identified SOEs do not disclose their emissions nor are estimates of these emissions available in the public domain. Despite these limitations, data compiled for this report covering almost 300 major SOEs suggest that SOEs globally are responsible for at least 7.49 gigatons of carbon dioxide equivalent (GtCO2e) annually in direct (Scope 1) emissions. While the true scale of SOE-related emissions is likely to be substantially higher, particularly when accounting for national oil companies and iron and steel manufacturers that do not currently report their emissions, this figure is over 1 GtCO2e greater than various previous estimates, and larger than the total annual emissions of any country except China.

Abstract:
The Paris Agreement included two particularly crucial innovations for supporting greenhouse gas emissions reductions: a voluntary, bottom-up nationally determined contribution (NDC) and a ratchet mechanism. The latter change meant that, in the run-up to the 26th Conference of the Parties (COP26) to the United Nations Framework Convention on Climate Change in Glasgow last fall, countries prepared updated NDCs—specific commitments to reduce emissions by 2030—that outlined their increased ambition. After the adoption of the Glasgow Climate Pact, many observers have focused on what these NDCs, as well as countries’ pledges to reach net-zero greenhouse gas emissions by certain dates, could mean for the world’s ability to limit global temperature rise to well below 2° Celsius—the central goal of the Paris Agreement. But another critical question remains: how would these targets and ambitions drive near-term emissions reductions. Understanding the answer can provide insights to investors, utilities, or others with decision time horizons of 10–15 years and that wish to align with net-zero ambitions. This report, part of the energy systems modeling program at Columbia University’s Center on Global Energy Policy, aims to assess the alignment between updated NDCs and current net-zero pledges for policy makers and industry leaders to gain insight into their own national and corporate decarbonization outlooks. It considers all classes of NDCs, including: 1) percentage reduction in emissions relative to a historical base year level, 2) percentage reduction compared to a 2030 business-as-usual scenario, and 3) reduction in emissions intensity of gross domestic product. It presents an estimate of the percentage reduction in greenhouse gases (GHGs) from 2015 to 2030 for all commitments outlined in NDCs for countries that also have a net-zero target. Overall, this analysis finds that the NDCs of economies with 2050 net-zero pledges would lead to a 27 percent reduction in GHG emissions by 2030, relative to 2015. However, countries with post-2050 net-zero pledges are projected to increase their emissions by 10 percent between 2015 and 2030, lowering the net global emission reduction to 9 percent over this period.

3. Sorry, but the Virus Shows Why There Won’t Be Global Action on Climate Change

Abstract:
The COVID-19 pandemic has disrupted daily life, caused widespread sickness and fatalities, and sent the global economy careening toward a depression. Governments have responded by taking unprecedented steps to shut down entire cities, ban travel, and isolate nations—extreme measures that are giving hope to climate activists that similarly ambitious policies might be possible to address global warming, which many consider a similar existential threat. Yet that would be the wrong lesson to draw, as the very same barriers preventing an effective COVID-19 response continue to keep climate change action out of reach. Scientists warn that the impacts of COVID-19 will rise sharply over time, threatening the lives of vast numbers of people, particularly those most vulnerable. They warn that climate change, too, will severely harm many over time, albeit not with the same rapidity. If governments and companies can take extreme actions to cancel sports seasons, shut down workplaces, and restrict movement, surely they can take similarly drastic steps to change how we produce and consume energy?

Abstract:
The social cost of carbon (SCC) is commonly described and used as the optimal CO2 price. However, the wide range of SCC estimates provides limited practical assistance to policymakers setting specific CO2 prices. Here we describe an alternate near-term to net zero (NT2NZ) approach, estimating CO2 prices needed in the near term for consistency with a net-zero CO2 emissions target. This approach dovetails with the emissions-target-focused approach that frames climate policy discussions around the world, avoids uncertainties in estimates of climate damages and long-term decarbonization costs, offers transparency about sensitivities and enables the consideration of CO2 prices alongside a portfolio of policies. We estimate illustrative NT2NZ CO2 prices for the United States; for a 2050 net-zero CO2 emission target, prices are US$34 to US$64 per metric ton in 2025 and US$77 to US$124 in 2030. These results are most influenced by assumptions about complementary policies and oil prices.

Abstract:
The case for rapid and profound decarbonization has never been more obvious or more urgent, and immediate action must match growing global ambition and need. An important new component of this discussion is the necessity of achieving net-zero global greenhouse gas emissions for any climate stabilization target. Until net-zero emissions are achieved, greenhouse gas will accumulate in the atmosphere and oceans, and concentrations will grow, even with deep and profound emissions reduction, mitigation, and adaptation measures. This places a severe constraint on human enterprise: any carbon removed from the earth must be returned to the earth.

Abstract:
Speaking at the Federal Energy Regulatory Commission Technical Conference regarding Carbon Pricing in Organized Wholesale Electricity Markets, adjunct senior research scholar David R. Hill delivered a statement on issues surrounding carbon pricing in the FERC-jurisdictional markets. The purpose of this conference was to discuss considerations related to state-adoption of mechanisms to price carbon dioxide emissions, commonly referred to as carbon pricing, in regions with Commission-jurisdictional organized wholesale electricity markets (i.e., regions with regional transmission organizations/independent system operators, or RTOs/ISOs). The conference focused on carbon pricing approaches where a state (or group of states) sets an explicit carbon price, whether through a price-based or quantity-based approach, and how that carbon price intersects with RTO/ISO-administered markets, addressing both legal and technical issues.

Abstract:
In August 2020, the Trump Administration finalized plans to roll back regulations on oil and gas industry emissions of methane from new and modified infrastructure. In the same month, the European Commission gathered stakeholder comments as part of its process to introduce the first EU-wide methane regulations. Though contradictory in direction, these regulatory processes on opposite sides of the Atlantic highlighted a critical climate protection challenge: How can the oil and gas industry—and the regulators who oversee it—best detect and address methane emissions to protect the environment and the climate in particular? The answer to this question will drive planning and operational approaches in the oil and gas industry. It could also significantly affect the future role of natural gas. Five years ago, many energy analysts expected natural gas to serve as a bridge fuel that would result in only half as much climate warming as coal, and fewer local air pollutants. Among other roles, gas was seen as a natural complement for variable wind or solar power—a way to provide firm, dispatchable, low-emissions power. Now that it is apparent that our understanding of methane emissions is poor, the climate implications of gas are far less clear. This poor grasp of methane emissions appears likely to become a thing of the past, however. In roughly the next five years, new satellite detection systems—used in concert with existing systems, aerial monitoring platforms, and ground-based monitors—can increase markedly the transparency surrounding methane leakage. The new wave of satellite monitoring capability has major implications for industry and governments. Our world is rapidly becoming a place in which methane emissions will have nowhere to hide. This commentary, co-authored by the Center on Global Energy Policy and TNO, focuses on detection and response to oil- and gas-related methane emissions, which have been the subject of increasing focus on the part of industry and the public policy community. It addresses the significance of methane emissions for the climate, and the challenges of detecting and accurately quantifying methane emissions. It then explores the evolving capabilities of satellite-based methane detection and monitoring systems, which are expected to advance rapidly in the coming years, and which can be especially powerful when used in concert with aerial and ground-based monitoring systems. It concludes with a discussion of the implications of the changing satellite detection landscape for the oil and gas industry, the finance and investment community, and the realm of public policy.

8. Expanding the Reach of a Carbon Tax: Emissions Impacts of Pricing Combined with Additional Climate Actions

Abstract:
Putting a price on carbon dioxide (CO2) emissions can help governments reduce them rapidly and in a cost-effective manner. While 10 carbon tax bills have been proposed in the 116th US Congress, carbon prices alone are not enough to reach net-zero emissions by midcentury. Additional policies are needed to complement an economy-wide carbon tax and further cut CO2 from the US energy system. This study aims to provide a better understanding of such policy combinations. It projects the energy CO2 emissions impacts of two carbon taxes, starting in 2021, that span the rates in the carbon tax bills in Congress. The “low” tax scenario starts at $30 per ton in 2021 and rises at 5 percent plus inflation per year, reaching $44 by 2030, while the “high” carbon tax starts at $15 per ton and rises $15 per year, reaching $150 by 2030. The paper then describes the barriers inhibiting emissions reductions beyond those achieved by the carbon taxes alone for each major sector: electricity, transportation, buildings, and industry. Finally, it explores the energy system changes needed to overcome those barriers and the policy interventions that could deliver those changes. For certain key energy system changes, it provides quantitative estimates of emissions reductions incremental to the two carbon taxes. This paper is part of a joint effort by Columbia University’s Center on Global Energy Policy (CGEP) and Rhodium Group to help policy makers and other stakeholders understand the important decisions associated with the design of carbon pricing policies and the implications of these decisions. The paper finds the emissions impacts of the low and high carbon taxes alone lead to economy-wide energy CO2 emissions reductions by 2030 of 33 percent and 41 percent, respectively, below 2005 levels. A carbon tax combined with policy actions that support comprehensive, ambitious energy system changes could lead to emissions reductions in the range of 40 to 45 percent, arguably consistent with US midcentury deep decarbonization goals for the energy system. In the 2020s, the bulk of these emissions reductions are likely to occur in the power sector, even under a broad decarbonization strategy, due to the significant barriers to large near-term emissions reductions in the transportation, buildings, and industrial sectors.
