Biophysical and economic limits to negative CO2 emissions


Abstract

To have a >50% chance of limiting warming below 2°C, most recent scenarios from integrated assessment models (IAMs) require large-scale deployment of negative emissions technologies (NETs). These are technologies that result in the net removal of greenhouse gases from the atmosphere. We quantify potential global impacts of the different NETs on various factors (such as land, greenhouse gas emissions, water, albedo, nutrients and energy) to determine the biophysical limits to, and economic costs of, their widespread application. Resource implications vary between technologies and need to be satisfactorily addressed if NETs are to have a significant role in achieving climate goals.

Global Carbon Budget 2016

The Global Carbon Project has released its 2016 edition of the world’s carbon budget, including historical emissions by country back to 1751. This multidisciplinary and international effort provides a set of consistent supporting data for further analysis.Learn more »

Global Carbon Budget Figures

Every year the Global Carbon Project publishes a number of figures demonstrating the latest global carbon budget, and these are freely available for use in a number of formats.Learn more »

Reaching peak emissions

Global emissions growth appears to have slowed in the last two years. Rob Jackson and colleagues discuss the causes for this and the potential for emissions to peak in the near future.Learn more »
