In particular, the academic definition of geoengineering is quite different than the popular conception of the term.“

„New methods such as decision pathway surveys may offer important insights for policy makers by capturing much of the depth and reasoning of small-group deliberations while meeting standard survey goals including large-sample stakeholder engagement. Pathway surveys also can help participants to deepen their factual knowledge base and arrive at a more complete understanding of their own values as they apply to proposed policy alternatives. The pathway results indicate more fully the conditional and context-specific nature of support for several “upstream” climate interventions, including solar radiation management techniques and carbon dioxide removal technologies.“

„As it is a plant-based CE option that extracts CO2 from the atmosphere, it might be considered a ‘green’ CE method that moves the biosphere closer to its natural, i.e. pre-Neolithic, state. Here, we test this hypothesis by comparing the biogeochemical (water- and carbon-related) changes induced by biomass plantations compared to those induced by historical human land cover and land use change. Results indicate that large-scale biomass plantations would produce a biogeochemical shift in the terrestrial biosphere which is, in absolute terms, even larger than that already produced by historical land use change.“
„The company behind the pilot project, Calgary-based[nbsp]Carbon Engineering, is one of a handful of businesses around the world working to develop „air capture“ technologies to remove planet-warming carbon dioxide from the atmosphere. These companies aim to mop up our waste carbon and help cool the planet, complementing efforts to reduce emissions and increase energy efficiency.„
„Blue Planet’s new biomimetic carbon capture and mineralization technology utilizes several patented scientific breakthoughs. Blue Planet uses it’s patented Liquid Condensed Phase (LCP™) Technology to convert CO2 into high-value CarbonMix™ building and highway materials. Blue Planet provides CO2 capture and sequestration, criteria pollutant removal, and water management services. We provide these services to emitters in the coal, gas, cement and refinery industries. Blue carbon is captured naturally by marine ecosystems to build coral reefs. Blue Planet uses a similar mineralization process to convert CO2 into carbon negative building materials.“
„In response to the rapid pace of global climate change, the Marin Carbon Project (MCP) seeks to enhance carbon sequestration in rangeland, agricultural, and forest soils through applied research, demonstration and implementation. Our vision is for landowners and land managers of agricultural ecosystems to serve as stewards of soil health and to undertake carbon farming in a manner that can improve on-farm productivity and viability, enhance ecosystem functions, and stop and reverse climate change.“
„Skytree ® has developed a technology that offers a highly effective way to capture CO2 directly from the air around us. We can store and release and use this CO2 in countless products and applications we use every day. We are working on prototypes, products and pilots for the following markets.“
Campaign by several NGOs. „No to 1.5°C with geoengineering! No to the lie of “GHG neutrality”!“
„Paris has been awash with hype about ‘CO2 recycling’ and ‘carbon neutral’ or even ‘carbon negative’ technologies based on burning millions of trees, writes Rachel Smolker. But the alchemical notion that waste carbon can be spun into corporate gold is hitting serious reality checks. It’s time to ditch the fantasies and progress the real solutions: like caring for land, soils, forests and grasslands.“
„In 2015, it became clearer than ever that industry is going to take serious action over the coming decades to reduce CO2 emissions. But what if businesses could go beyond stopping CO2 emissions, and actually pull more CO2 out of the atmosphere than they emit into it? With carbon removal (aka “negative emissions”) solutions, that vision could one day become a reality. And while building “net-sequestration” companies will be a monumental task, 2015 has seen a number of encouraging signs about the potential for a carbon-removing economy of the future. Here’s a recap of the key milestones around carbon removal from the past year, and what it means for sustainable business in 2016 and beyond.“
