The global food system is an important contributor to greenhouse gas emissions that lead to climate change. Animal agriculture is responsible for a large share of the food-system emissions, both directly and through the production of animal feed. Limiting global warming to the goals set forth by...

Using new surveys on more than 40,000 respondents in twenty countries that account for 72% of global CO2 emissions, we study the understanding of and attitudes toward climate change and climate policies. We show that, across countries, support for climate policies hinges on three key perceptions...

This paper provides stated preference (SP) estimates of the average social cost of carbon (ASCC) for use in evaluation of the benefits and costs of climate policy. Based on a U.S. nationally representative survey, we find an average individual willingness-to-pay (WTP) of $1,116 per year to keep...

In recent years the analysis of US climate policy on the electricity sector has predominantly deployed electricity planning or capacity expansion models that use deterministic or equilibrium optimization methods. While uncertainty in key input assumptions is considered, it is usually restricted...

The phasedown of coal for electricity generation is considered vital to meeting global climate targets. Many countries have pledged to stop using coal, with some as early as 2030. While the United States has no target currently in place, several states do. In this paper, we examine the...

Advocates in several countries have promoted a "green recovery" from the pandemic, with an emphasis on measures to address climate objectives. We evaluate proposals for the United States and find that as stated, ambitious plans to further cut emissions from transportation and electricity will...

Many US states have set ambitious renewable portfolio standards (RPS) that require utilities to switch from fossil fuels toward renewables. RPS increases the renewables capacity, bond issuance, maturity, and yield spreads of investor-owned utilities compared to municipal producers that are...

This paper investigates the impact of carbon pricing on the economy, with a focus on European carbon taxes and the carbon market. Our analysis reveals three key findings. First, while both policies have successfully reduced emissions, the economic costs of the European carbon market are larger...

This paper demonstrates how three important results in environmental economics, true under mild conditions in closed economies, are false or need serious amendment in a world with international trade in goods. Since the three results we highlight have framed much of the ongoing discussion and...

Climate modelers have recognized the possibility of abrupt climate changes caused by a reorganization of the North Atlantic's current pattern (technically known as a thermohaline circulation collapse). This circulation system now warms north-western Europe and transports carbon dioxide to the...
