BACKGROUND Net emissions of CO2 by human activities—including not only energy
services and industrial production but also land use and agriculture—must approach zero in …

Hydrogen can power transportation with near zero greenhouse gas emissions. With
government support, early market development is now underway in several nations thanks …

The most recent IPCC assessment has shown an important role for negative emissions
technologies (NETs) in limiting global warming to 2 C cost-effectively. However, a bottom-up …

Bioenergy with carbon capture and storage (BECCS) is gaining increasing attention not only
as a carbon-neutral alternative to fossil fuels as an energy source, but also as one of the …

The continuous temperature rise has raised global concerns about CO2 emissions. As the
country with the largest CO2 emissions, China is facing the challenge of achieving large …

As China ramped-up coal power capacities rapidly while CO2 emissions need to decline,
these capacities would turn into stranded assets. To deal with this risk, a promising option is …

For aiming to keep global warming well-below 2° C and pursue efforts to limit it to 1.5° C, as
set out in the Paris Agreement, a full-fledged assessment of negative emission technologies …

Capture and permanent geologic sequestration of biogenic CO2 emissions may provide
critical flexibility in ambitious climate change mitigation. However, most bioenergy with …

The sustainability of air transport is increasingly studied in relation to climate issues. The
objective of this paper is to provide the key elements for assessing whether a given …

The Paris Agreement, ratified by 181 countries, agrees to limit global warming to “well
below” 2 C. To fulfil this pledge, total global carbon dioxide (CO2) emissions post-2010 must …
