Human respiration was estimated to release 0.6 GtC year−1 and that of their associated domestic animals was estimated to release 1.5 Gt C year−1, to which an indirect release of 1.0 Gt C year−1, derived from decomposition of the organic waste and garbage produced by humans and their domestic animals, must be added.
This Review provides a historical overview of the field of DAC, along with an exhaustive description of the use of chemical sorbents targeted at this application.
Microalgae can be cultivated on non-fertile land with unit CO2 fixation capacity 10–50 times higher than terrestrial plants. Production of food, feed, fine chemicals, and biofuels from microalgal biomass could further enhance the benefits of microalgae-based CO2 fixation.
BEAM Plus defines best practice criteria for a range of sustainability issues across the whole life-cycle of buildings and projects.
