The feasibility of low CO2 concentration targets and the role of bio-energy with carbon capture and storage (BECCS)

The United Nations Framework Convention on Climate Change (UNFCCC 1992) calls for stabilization of atmospheric greenhouse gas (GHG) concentrations at a level that would prevent dangerous anthropogenic…

Sharing the reduction effort to limit global warming to 2 degree C

In order to stabilise long-term greenhouse gas concentrations at 450 ppm CO 2 eq or less, developed countries as a group should reduce emissions by 25 to 40% below 1990 levels, by 2020, while…

Increasing anthropogenic nitrogen inputs and riverine DIN exports from the Changjiang River basin

Our result indicates that anthropogenically enhanced N inputs dominate and will continue to dominate river DIN yields under changing human pressures in the basin. Therefore, nitrogen pollution is and…

Sharing developed countries’ post-2012 greenhouse gas emission reductions based on comparable efforts

The Bali Action Plan as adopted under the United Nations Framework Convention on Climate Change (UNFCCC) in 2007, states that Annex I (developed) countries should reduce their greenhouse gas emissions…

Downscaling socioeconomic and emissions scenarios for global environmental change research: a review

Global change research encompasses various scales from global to local. Impacts analysis in particular often requires spatial downscaling, whereby socioeconomic and emission variables specified at…

Postponing emission reductions from 2020 to 2030 increases climate risks and long-term costs

Substantially postponing the emission reductions, compared to the ranges indicated in IPCC’s recent assessment for 2020 as required for meeting the longterm 2°C target, increases the risk of exceeding…

Indirect effects of biofuels: intensification of agricultural production

Agricultural intensification has the potential to reduce indirect land-use change from biofuels. If such intensification is realised only by applying more fertiliser, this may lead to substantial…

Historical (1850-2000) gridded anthropogenic and biomass burning emissions of reactive gases and aerosols: Methodology and application

In this paper a new dataset of gridded emissions covering the historical period (1850–2000) in decadal increments at a horizontal resolution of 0.5° in latitude and longitude is presented and…

Greenhouse gas emissions for the EU in four future scenarios

The European Common Agricultural Policy (CAP) will be revised in the near future. A proposed agricultural policy reform will affect many dimensions of the sustainable development of agriculture. One…

Identifying the indirect effects of bio-energy production

Bio-energy has the potential to reduce greenhouse gas (GHG) emissions. Indirect effects might partly or even completely undo this advantage. Indirect land use change (ILUC) – leading to emissions and…
