Forget #carbonneutral, Northwestern develops #carbonNEGATIVE #concrete
Using a combination of seawater, electricity, and carbon dioxide (CO2), scientists at Chicago‘s Northwestern University Engineering have developed a new building material that goes beyond reducing emissions. The new material acts like concrete, but actively captures CO2 that’s already in the air and locks it away. Permanently.

Electrek · Forget carbon neutral, Northwestern develops carbon NEGATIVE concreteBy Jo Borrás

"How meat and milk companies are racing to ease your climate guilt."

washingtonpost.com/climate-env

WaPo finally posted a modest critique of meat industry greenwashing.

<💬>
Under another new California law, companies also must disclose the emissions created throughout their supply chains, and the Securities and Exchange Commission is working on a similar requirement.

It all has big food companies rushing to show progress in cutting emissions, particularly after so many of them promised to zero out their net release of greenhouse gases — known as going “carbon neutral” — by 2050 or earlier, in alignment with the Paris agreement on global warming. In the backdrop is a contentious debate over how those companies should calculate their carbon footprints.

The fight has shifted to an obscure independent organization called the GHG Protocol, a group made up of corporations, scientists and environmental groups that writes accounting rules for greenhouse gas emissions that will guide what climate claims companies can make under new state laws.

Among the companies involved in determining when and how farming and harvesting methods can be used to erase the emissions impact of products like hamburgers and dairy are McDonald’s, Nestlé and the Global Roundtable for Sustainable Beef, to which meat giants Tyson Foods and Cargill belong.

The deliberations of the GHG Protocol, which is managed by the World Resources Institute and the World Business Council for Sustainable Development, are kept confidential. But discord spilled into public in the fall, following its publication of draft guidelines for farm and forestry emissions. Dozens of environmental groups and academics say the rules as proposed would allow companies to declare climate-unfriendly products such as lumber, paper, beef and milk carbon neutral — or even carbon negative — by making modest land use adjustments that don’t truly mitigate the emissions of those products.

There's certainly going to be more and more tension due to these corporations trying to find better greenwashing, better methods of faking data, more sophisticated bullshit.

It's going to get a lot worse before they lose.

"An assessment by environmental contractor James Salazar, who is now Sustainability Director at WAP Sustainability, showed that the Remy-Mead concrete is carbon-negative, trapping more CO2 than is emitted during its production."

OutriderEco-concrete is Cementing Itself as a Climate SolutionA race is on to change how concrete is made and reduce the huge carbon footprint of the world’s most ubiquitous building material.

A new study claims that global agriculture could become carbon-negative by 2050, removing more CO2 than it emits. The study explores various scenarios of dietary change and technological innovation that could achieve this goal. This would require a radical food system transformation involving all actors and sectors.

@davidho just like an ICE car manufacturer investing in electric vehicles? or a petrochemical company investing in recycling technologies? an electric company installing PV and wind turbines?
what is disturbing for you: two businesses coexisting? the transition from one to another?

dato che siamo in pieno boom minerario, e in qualche caso reshoring di produzioni pesanti, vale la pena considerare che gli scarti (abbondanti) di queste produzioni sono spesso alcalini, e perciò possono essere utili a sequestrare CO2. Esempi notevoli in Italia potrebbero essere le scorie d'altoforno #ilvataranto , fanghi rossi #portovesme (legati anche al recupero di #Gallio) polveri di cementifici, ceneri alcaline... #circulareconomy #carbonnegative #ccs

NatureThe negative emission potential of alkaline materials - Nature CommunicationsThe potential of biomass energy carbon capture and storage is unclear. Here the authors estimated the negative emissions potential from highly alkaline materials, by-products and wastes and showed that these materials have a CO2 storage potential of 2.5–7.5 billion tonnes per year by 2100.

@eigengott @gwagner put in that way I might like to cut trees for planting wind farms,
but I'm a good person.
anyway I (pretend I) don't understand people that count trees instead of weighting what they (say they want to) plant. trees just "hold" carbon, we need sinks to go from 420 ppm to 300 ppm #carbonnegative
