Nonprofit Partisanship

We establish a novel measurement of nonprofit organization ideology using semantic text analysis and validate it with a large-scale online experiment. On average, health- related nonprofits as well as education-related organizations, including US universities, are the most left-leaning group. Religion-related nonprofits, on the other hand, are the most conservative. We then examine whether ”rage donations” for selected lib- eral nonprofits right after the Trump elections documented by the media hold true more generally across different sectors over different presidential elections. We find no evidence that expected shifts in ideology of a government systematically influence donations differently depending on nonprofit ideology

Greenhouse gas emissions from U.S. crude oil pipeline accidents:1968 to 2020

Abstract Crude oil pipelines are considered as the lifelines of energy industry. However, accidents of the pipelines can lead to severe public health and environmental concerns, in which greenhouse gas (GHG) emissions, primarily methane, are frequently overlooked. While previous studies examined fugitive emissions in normal operation of crude oil pipelines, emissions resulting from accidents were typically managed separately and were therefore not included in the emission account of oil systems. To bridge this knowledge gap, we employed a bottom-up approach to conducted the first-ever inventory of GHG emissions resulting from crude oil pipeline accidents in the United States at the state level from 1968 to 2020, and leveraged Monte Carlo simulation to estimate the associated uncertainties. Our results reveal that GHG emissions from accidents in gathering pipelines (~720,000 tCO2e) exceed those from transmission pipelines (~290,000 tCO2e), although significantly more accidents have occurred in transmission pipelines (6883 cases) than gathering pipelines (773 cases). Texas accounted for over 40% of total accident-related GHG emissions nationwide. Our study contributes to enhanced accuracy of the GHG account associated with crude oil transport and implementing the data-driven climate mitigation strategies
