Global and regional drivers of land-use emissions
Nature | January 27, 2021

We estimate country-, process-, GHG- and product-specific land-use emissions 1961-2017. Total emissions have increased to 14.6 GtCO2-eq in 2017 (~25% of anthropogenic GHG emissions). Our results may help prioritize mitigation efforts, but suggest drastic reductions in emissions will require similarly drastic changes in agricultural production and/or practices.

Research Brief

Radiative effects of aerosols may offset the air quality penalty of climate change in China
Nature Climate Change | August 3, 2020

We show that direct radiative effects of short-lived aerosols may substantially offset the "climate penalty" that prior studies have shown (i.e. that future climate change is likely to worsen air quality and thereby human health in most regions by favoring weather conditions that increase concentrations of air pollution).

Ozone and climate impacts on California's key crops
Nature Food | March 16, 2020

By analyzing 35 years of temperature, ozone levels, and crop yield data, we estimate the impacts of warming and ozone pollution on perennial fruits and nuts in California. These crops, which represent ~38% of the state's agriculture by value, suffer damages of about $1 billion per year due to ozone in recent years. With 2°C of warming, almond yields will drop by ~10%.

Climate effects on Chinese air pollution deaths
PNAS | August 12, 2019

Future climate change may exacerbate the impacts of Chinese air pollution by increasing the frequency and duration of weather conditions that enhance pollution exposure. Under a scenario that avoids 3°C of mean warming but holds emissions constant, we estimate 12,100 and 8,900 more Chinese will die each year from PM2.5 and ozone exposure, respectively.

Committed emissions from existing energy infrastructure jeopardize 1.5°C climate target
Nature | July 1, 2019

If operated as historically, existing fossil energy infrastructure will emit >650 Gt of CO2, well over the most recent 1.5°C carbon budgets and 2/3 of the remaining 2°C budget. There is thus little or no room for new fossil infrastructure under the targets; rather existing infrastructure must be retired early.

Infrastructure shapes differences in the carbon intensities of Chinese cities
ES&T | April 25, 2018

Differences in Chinese cities’ carbon intensity are largely due to disparities in economic structure that can in turn be traced to past investment-led growth. Related carbon lock-in may hinder China’s efforts to reduce emissions from activities in urban areas.

Global super-polluting power plants
Nature Sustainability | January 8, 2018

We assess fuel- and region-specific opportunities for reducing undesirable air pollutant emissions using a newly developed emission dataset at the level of individual generating units. Retiring or installing emission control technologies on units representing 0.8% of the global coal-fired power plant capacity could reduce levels of PM2.5 emissions by 8–14%.

Variations of China’s emission estimates: response to uncertainties in energy statistics
Atmospheric Chemistry & Physics | January 25, 2017

Hong et al. attempt to improve the understanding of uncertainties in China’s energy statistics and evaluate their impacts on China’s emissions during the period of 1990–2013.
