Europe is launching an ambitious mission to decarbonize many of its urban areas within a decade. But is it realistic?

Comparing Impacts of CO2 and Particle Emission Reductions
Black carbon contained in airborne particles is often cited as a major factor warming the climate, but how much can California reduce climate change through reducing airborne particle concentrations?
Greening the Friendly Skies
Decarbonizing the aviation industry won’t be easy. The coronavirus pandemic complicates the situation but also presents an opportunity.
Global North Is Responsible for 92% of Excess Emissions
The United States and European Union bear disproportionate liability for emitting to the atmospheric commons, new research argues.
Using Dirt to Clean Up Construction
The construction industry is one of the world’s largest emitters of carbon dioxide. Whether it can reduce those emissions depends on replacing its most common building material.
Committed U.S. Power Emissions Incompatible with Paris Agreement
Without a significant reduction in usage, committed emissions from coal and gas plants in the United States are already incompatible with the country’s pledges under the Paris climate agreement.
Downhill from Here: Landscape Positions and Greenhouse Emissions
In comparing soils from two tundra wetland landscape positions, landscape position is found to matter, and toeslopes are associated with higher greenhouse gas production.
Experiments Reveal How Permafrost Carbon Becomes Carbon Dioxide
Field samples from Alaska show how sunlight and iron convert permafrost carbon to carbon dioxide. Climate models ignore this process.
Will COVID’s Cleaner Skies Muddy Climate Models?
Reduced greenhouse gas emissions for a year or two won’t slow down climate change, but they may throw off scientists’ ability to model short-term phenomena.
Radioactive Bookkeeping of Carbon Emissions
A new sampling method uses carbon-14 to single out which carbon dioxide molecules in the atmosphere derive from fossil fuels. The method could help track emissions goals for climate mitigation.
