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.

2. Investing in the US Natural Gas Pipeline System to Support Net-Zero Targets

Abstract:
The Biden administration’s move to bring the United States back into the Paris Agreement and lower greenhouse gas emissions to address climate change will, if carried through, lead to a reduction in fossil fuel consumption. Cutting back on the burning of coal, oil, and natural gas will be critical to transitioning the country to the lower-carbon energy system it needs to achieve decarbonization targets. But while it may seem counterintuitive, investing more in the domestic natural gas pipeline network could help the US reach net-zero emission goals more quickly and cheaply. Fortifying and upgrading the system could prepare the existing infrastructure to transport zero-carbon fuels as they become available and, in the meantime, reduce harmful methane leaks from natural gas. Studies by energy agencies, universities, and the industry that model future US natural gas consumption consistently show continued use of natural gas for at least the next 30 years, even in scenarios where the country achieves net-zero targets by midcentury. There is no quick replacement for gas in the US energy mix. And for many of the needs natural gas currently meets, the eventual replacement may be zero-carbon gaseous fuels (e.g., hydrogen, biogas). These fuels may play a significant role in supporting reliability and making the energy transition more affordable—but they, too, will require a pipeline network for efficient delivery to markets and end users. Building new pipelines is a time-consuming and costly process, especially when added to all the other infrastructure needs associated with the energy transition. When possible, adjusting existing infrastructure—already permitted and built—can help minimize the costs and accelerate the speed of the transition. The US has 2.5 million miles of natural gas pipeline infrastructure across the country, which, with investment, could be upgraded to cut emissions and be retrofitted for future transport of cleaner fuels. However, investments in pipeline infrastructure have drawn concern that they would lock fossil fuels into the US energy mix for a longer period of time and work against the energy transition. Such concerns are understandable given the contribution of fossil fuels to the global climate crisis. But retrofitting and otherwise improving the existing pipeline system are not a choice between natural gas and electrification or between fossil fuels and zero-carbon fuels. Rather, these investments in existing infrastructure can support a pathway toward wider storage and delivery of cleaner and increasingly low-carbon gases while lowering the overall cost of the transition and ensuring reliability across the energy system. In the same way that the electric grid allows for increasingly low-carbon electrons to be transported, the natural gas grid should be viewed as a way to enable increasingly low-carbon molecules to be transported. This paper, part of the work by Columbia University’s Center on Global Energy Policy on natural gas and the energy transition, examines projections of continued natural gas use and the zero-carbon fuels that are poised to become a bigger part of the energy mix. It details the state of the existing US natural gas pipeline network and trends within this segment of the market, as well as technical considerations for moving new, zero-carbon fuels through the system. The findings, combined with potential net-zero goals, lead to recommendations for curbing greenhouse gas emissions caused by leakage in the existing network, as well as opportunities to refurbish sections to carry increasing levels of cleaner fuels. It focuses on policy options that will minimize environmental impacts and maximize economic benefits. These options fall into two main categories: changing regulations on methane leak detection and repair to make the existing pipeline network as low emissions as possible while it still transports natural gas, and expanding on existing regulatory authority to allow for retrofitting the system for more hydrogen usage, along with increased R&D funding to test the integrity of the pipeline system with greater levels of hydrogen and other zero-carbon fuels.

Abstract:
For Kristin Smith, MAAS alum and Cultural Affairs Officer for the U.S. Embassy in Beirut, culture and diplomacy go hand-in-hand. “My job is really using culture and art to bring people closer together,” Smith told the Lebanese newspaper The Daily Star at a U.S. Embassy event celebrating the Lebanese writer Khalil Gibran. “It’s not just about deepening our ties and getting to know each other on a cultural level though. If we have these similarities in [the arts], then perhaps that will lead to future cooperation in other ways.” During her time in the MA in Arab Studies program, Smith—who holds a BA in Near Eastern Languages and Civilization from Harvard—pursued an academic concentration in Culture and Society, managed a yoga studio, and served as a Public Diplomacy Fellow at the U.S. Consulate General in Casablanca. Following graduation, she joined the Foreign Service, serving in Taiwan before beginning her current position in 2017. Her portfolio as Cultural Affairs Officer covers five primary issues: arts and culture, non-formal education, academic outreach, interfaith and minority outreach, and alumni programming.
