This paper investigates the health impacts of fossil fuel-driven energy production by exploiting a unique Colombian electricity pricing policy. This policy triggers increased thermal energy production when wholesale electricity prices exceed a pre-determined scarcity price, resulting in heightened local pollution levels. Comparing municipalities near high-capacity thermal plants to those near low-capacity plants, the study reveals a significant increase in cardiovascular-related emergency room mortality (56%) and respiratory-related morbidity (9%) in areas with heightened thermal energy production. These findings translate into substantial health costs, estimated at 996 million USD, considering lives lost and increased healthcare expenditures. The study’s focus on Colombia contributes valuable insights into the health consequences of fossil fuel-based energy production in lower-income countries, shedding light on the global

Wind energy resource estimates commonly depend on simulated wind speed profiles generated by reanalysis or weather models due to the lack of long time series measurements with sufficient coverage at relevant heights (roughly 90 m above ground). However, modeled data, including reanalyses, can be noisy and display a wide range of biases and errors, variously attributed to terrain effects, poor coverage of assimilated inputs, and model resolution. Wind generation records, if available at high temporal and geographical resolution, can provide a proxy for wind measurements and allow for evaluation of reanalyses and weather model wind time series. We use a 7-year-long data set of hourly, plant-level generation records from over 100 wind plants across Texas to evaluate two commonly used

Global coal use must be phased out if we are to minimize temperature increases associated with climate change. Most new coal plants are being built in the Asia Pacific and rely on overseas finance, with Indonesia and Vietnam the leading recipients. However, the politics of coal plant finance are changing, with many proposals cancelled in recent years. This article explores the factors that led to coal plant cancellations in Vietnam and Indonesia. Based on new data of coal plant finance and elite interviews, we find fuel switching, public opposition, and national planning were the dominant reasons for cancellations in Vietnam, while Indonesia’s reasons were more diverse. Vietnam also had a larger number of cancellations than Indonesia, the latter of

Traditionally, analysis of the costs of cutting greenhouse gas emissions has assumed that governments would implement idealized, optimal policies such as uniform economy-wide carbon taxes. Yet actual policies in the real world, especially in large federal governments, are often highly heterogeneous and vary in political support and administrative capabilities within a country. While the benefits of heterogeneous action have been discussed widely for experimentation and leadership, little is known about its costs. Focusing on the United States, we represent plausible variation (by more than a factor of 3) in the stringency of state-led climate policy in a process-based integrated assessment model (GCAM-USA).

The most precipitous contraction of the global economy in a century has seen carbon emissions plummet. By the end of this year, emissions are likely to be 8% less than in 2019 — the largest annual percentage drop since the Second World War. To avert a global recession, governments are injecting trillions of dollars into stimulating their economies. The International Monetary Fund anticipates economic recovery by the end of this year, provided there are no further large outbreaks of disease. If nothing else changes, then emissions will tick upwards once more, as they have after each recession since the first oil shock of the early 1970s. The analysis we present here examines past recoveries to find lessons that help

Meeting climate goals requires ‘rapid and far-reaching transitions in energy, land, urban and infrastructure (including transport and buildings) and industrial systems. These systems transitions are unprecedented in terms of scale, but not necessarily in terms of speed…’ How can this be achieved? This report is for the governments and businesses that are interested in accelerating deep decarbonisation of the world economy.
