“Innovation is central to the Sustainable Development Scenario. Almost 35% of the cumulative CO2 emissions reductions seen in the Sustainable Development Scenario by 2070 compared with the current trajectory come from technologies that are currently at the prototype or demonstration phase and that will not become available at scale without further R[&]D (including commercial demonstrators) and technical improvements.”
“It comes at a time when policymakers and business leaders are under intensifying pressure to deliver on promises made as part of the landmark Paris Agreement ahead of this year’s COP26, due to be held in Glasgow, Scotland in early November.”
“This column argues that an alternate type of policy, called ‘carbon shares’, can limit emissions as efficiently as carbon taxes or caps while also properly incentivising negative emissions.”
“We are the world’s first aggregated data source for carbon offsetting.”

“A promising approach for de-risking brucite-bearing ultramafic tailings is in situ cementation via carbon dioxide (CO2) mineralization, which also sequesters this greenhouse gas within carbonate minerals. In cylindrical test experiments, brucite [Mg(OH)2] carbonation was accelerated by coupling organic and inorganic carbon cycling. Waste organics generated CO2 concentrations similar to that of flue gas (up to 19%).”

“Here we explore soil amendment with powdered basalt in natural ecosystems.”
“The problem we face lies not in the future, but of the here and now as a result of our previous emissions. Tackling this will require the deployment of negative emissions technologies – technologies or approaches which take greenhouse gases out of the atmosphere.”
“Sketch of a decentralized mineralization-based carbon capture: suppliers stake on reported deposits of mineral dust in publicly-auditable locations.”
“Today, the U.S. Department of Energy’s (DOE) Office of Fossil Energy and Carbon Management (FECM), in collaboration with the Office of Nuclear Energy and the Office of Energy Efficiency and Renewable Energy’s Geothermal Technology Office, issued a notice of intent (NOI) for a Funding Opportunity Announcement (FOA) expected to support front-end engineering design (FEED) studies of direct air capture (DAC) combined with dedicated storage and coupled to existing low-carbon energy.”
