SDG 13

With rising greenhouse gas emissions, climate change is occurring at rates much faster than anticipated and its effects are clearly felt worldwide. While there are positive steps in terms of the climate finance flows and the development of nationally determined contributions, far more ambitious plans and accelerated action are needed on mitigation and adaptation. Access to finance and strengthened capacities need to be scaled up at a much faster rate, particularly for least developed countries and small island developing States.

The Zero Carbon Action Plan (ZCAP) will serve as a roadmap for the U.S. based on the latest modeling, research and understanding of decarbonizing six key sectors (power, transport, industry, buildings, food and land use, and materials) supported by technical pathways to zero carbon by 2050, as well as supporting policy recommendations. The ZCAP was designed by a cohort of nearly 100 researchers and 19 Chairs who make up the Zero Carbon Consortium, who are experts in their fields of climate change policy; clean energy pathways modeling; industrial policy high-employment green economies; legislative and regulatory policy; electricity (power) generation; transportation; industry; buildings; sustainable land-use; and sustainable materials management.

The COVID-19 crisis has precipitated the largest decline of global greenhouse gas (GHG) emissions on record. Those massive current declines are likely temporary, but they raise important questions about the trajectory of emissions as the economic crisis abates and economic activity resumes. Given the increasing importance of “bottom-up” action on climate, this analysis inventories the various GHG reduction pledges and commitments of the 100 largest U.S. cities; estimates the emissions savings that could result from those pledges; and then evaluates whether U.S. cities appear to be on track to meet their pledges. In this fashion, the information addresses the current array of results on the ground in order to inform ongoing discussions of the potential and limits of “bottom-up”

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

Estimation of pollution impacts on health is critical for guiding policy to improve health outcomes. Estimation is challenging, however, because economic activity can worsen pollution but also independently improve health outcomes, confounding pollution–health estimates. We show that future climate change driven changes in Saharan rainfall—a control on dust export—could generate large child health impacts, and that seemingly exotic proposals to pump and apply groundwater to Saharan locations to reduce dust emission could be cost competitive with leading child health interventions.

The economic free fall accompanying the coronavirus pandemic has, by some measures, made the world a cleaner place. Air pollution in Chinese, Indian, and U.S. cities is way down. In China alone, lower air pollution may have saved more lives than the virus has killed so far. In New York City, some pollutants dropped by more than half in just a week. Global emissions of carbon dioxide, the chief long-term cause of climate warming, are on track to drop by eight percent this year. All that cleaner air has come at a huge, unacceptable cost. But could the pandemic lay the foundation for more serious action to protect the environment—including on the greatest of all environmental problems, climate change?

This paper examines the effect of stringent environmental regulations on firms’ environmental practices, economic performance, and environmental innovation. Reducing COD levels by 10% relative to 2005 levels is an aim of the Chinese 11th Five-Year Plan. We find that more stringent environmental regulations faced by firms are positively associated with a greater probability of reducing COD emissions; also, there exists an evident heterogeneous effect across industries with different pollution intensities. Stricter environmental regulations also account for the sharp decline in firms’ profits, capital, and labor. We find that firms rely more on recycling and abatement investment than on innovations when meeting environmental requirements.

We play a series of incentivised laboratory games with risk-exposed co-operativised Guatemalan coffee farmers to understand the demand for index-based rainfall insurance. We estimate an explicit utility curve for every player and hence predict expected utility demand under counterfactual scenarios. Using these estimates, we provide a precise money-metric decomposition of the extent to which the low observed demand for index insurance is driven by expected utility theory, or by behavioural issues arising from a prospect-style utility structure. Our results suggest that consumers value probabilistic insurance using a prospect-style utility function that is concave both in probabilities and in income.

Artificial intelligence helps make markets more efficient and easier for analysts and market participants to understand highly complex phenomena—from the behavior of electrical power grids to climate change. There is no reason to believe that these more efficient markets, on their own, will tackle the carbon problem. Instead, they will require overt policy signals.

This paper estimates the country-level contributions to the social cost of carbon (SCC) using recent climate model projections, empirical climate-driven economic damage estimations and socio-economic projections. Central specifications show high global SCC values (median, US$417 per tonne of CO2 (tCO2); 66% confidence intervals, US$177–805 per tCO2) and a country-level SCC that is unequally distributed.

One of the most significant impacts of the United Nations Framework Convention on Climate Change (UNFCCC) has been the establishment of a participatory process for Reducing Emissions from Deforestation and Forest Degradation (REDD+). We analyse the case of Brazil, the country whose land-use emissions from deforestation and forest degradation have declined the most. Through semi-structured interviews with 29 country policy experts – analysed in full text around 7 categories of activities that existing literature identifies as central elements of an effective governance system – we find weak links between the international REDD+ system and what actually happens on the ground inside Brazil.

In many jurisdictions, policy-makers are seeking to decentralize the electric power system while also promoting deep reductions in the emission of greenhouse gases (GHG). We examine the potential roles for residential energy storage (RES), a technology thought to be at the epicenter of these twin revolutions. When operated with the goal of minimizing emissions, RES can reduce average household emissions by 2.2–6.4%. While RES is costly compared with many other emission-control measures, tariffs that internalize the social cost of carbon would reduce emissions by 0.1–5.9% relative to cost-minimizing operation. Policy-makers should be careful about assuming that decentralization will clean the electric power system, especially if it proceeds without carbon-mindful tariff reforms.

Climate variability and change are issues of growing public health importance. We analyzed hospitalization data for three unique climate regions of San Diego County alongside temperature data spanning 14 years. Within the milder coastal region where access to AC is not prevalent, heat-related morbidity was higher in the subset of zip codes where AC saturation is lowest. We detected a 14.6% increase in hospitalizations during hot weather in comparison to colder days in coastal locations where AC is less common, while no significant impact was observed in areas with higher AC saturation. Disparities in AC ownership were associated with income, race/ethnicity, and homeownership. Given that heat waves are expected to increase with climate change, understanding health impacts of heat
