Research Needs: Greenhouse gas (GHG) emissions from the transportation sector account for about 27% of the total GHG emissions in the United States. Due to increased travel demand and limited improvement in fuel efficiency, the GHG emissions from transportation have increased by 16% since 1990 (USEPA, 2015). About 80% of transit buses are currently powered by diesel engines, which are a primary...

In this study, we explore the decarbonisation pathways of four carbon and energy-intensive industries (respectively iron & steel, clinker cement, chemicals pulp paper) in context a global 2050 net-zero emissions objective using IMAGE integrated assessment model. We systematically test robustness model by studying its responses to different narratives across six world regions. The study underpin...

The social cost of carbon – or marginal damage caused by an additional ton of carbon dioxide emissions – has been estimated by a U.S. government working group at $21/tCO2 in 2010. That calculation, however, omits many of the biggest risks associated with climate change, and downplays the impact of current emissions on future generations. Our reanalysis explores the effects of uncertainty about ...

Emissions of various C2-C10 hydrocarbons (VOCs) and halogenated hydrocarbons (VHOCs) from a boreal wetland and a Scots pine forest floor in south-western Finland were measured by the static chamber technique. Isoprene was the main non-methane hydrocarbon emitted by the wetland, but small emissions of ethene, propane, propene, 1-butene, 2-methylpropene, butane, pentane and hexane were also detec...
