Urban public transit agencies spend billions of dollars each year on workers, durable capital and energy to supply transportation services. During a time of rising concern about climate change, the urban public transit sector has not significantly reduced its carbon footprint. Using data for the...

We present results from a randomized controlled trial in Bangladesh that introduced operational practices to improve energy efficiency and reduce emissions in 276 "zigzag" brick kilns. 65% of intervention kilns adopted the improved practices. Treatment assignment reduced energy use by 10.3%...

The most cost-effective policies for achieving CO2 abatement (e.g., carbon taxes) fail to get off the ground politically because of unacceptable distributional consequences. This paper explores CO2 abatement policies designed to address distributional concerns. Using an intertemporal numerical...

To reliably achieve deep decarbonization of the US power sector, a candidate policy must perform robustly across a range of possible future trajectories of demand, fossil fuel prices, and prices of new wind and solar capacity. Using a modified version of the NREL ReEDS model with scenarios that...

We assess the CO₂ fertilization effect on US agriculture using spatially-varying CO₂ data from NASA's Orbiting Carbon Observatory-2 (OCO-2) satellite covering the majority of US cropland under actual growing conditions. This study complements the many CO₂ enrichment experiments that have found...

Electrification of transportation and buildings to reduce greenhouse gas (GHG) emissions requires massive switching from natural gas and refined petroleum products. All three end-use energy sources are mispriced due in part to the unpriced pollution they emit. Natural gas and electricity...

We examine the real effects of the Greenhouse Gas Reporting Program (GHGRP) on electric power plants in the United States. Starting in 2010, the GHGRP requires both the reporting of greenhouse gas emissions by facilities emitting more than 25,000 metric tons of carbon dioxide per year to the...

We study local carbon policy to address the consequences of climate change. Standard analysis suggests that the social cost of carbon determines optimal carbon policy. We start by using the spatial integrated assessment model in Cruz and Rossi-Hansberg (2021) to measure the local social monetary...

Decarbonization and electrification will require a transformed electricity grid. Our long-run model of entry and exit of generation and storage capacity captures crucial aspects of the electricity industry such as time-varying demand for electricity, intermittency of renewables, and...

We present an integrated framework to understand the emissions impact of unilateral overlapping policies within a carbon-pricing system. "Internal carbon leakage" captures emissions displacement within the system (e.g., due to greater product imports from a neighbouring country). The waterbed...
