To capture CO2 in the US, climate tech startups partner with oil and gas
Climeworks, the Swiss company that’s capturing CO2 emissions for Microsoft, Stripe, and Shopify, is crafting plans to expand across the US, which is becoming the destination for companies that want to suck carbon dioxide out of the atmosphere.
“The US is a very interesting place, perhaps the most interesting place at the moment … from a market perspective, but also from a policy perspective,” says Christoph Beuttler, Climeworks’ chief climate policy officer. The Inflation Reduction Act more than tripled tax credits for direct air capture (DAC) and storage projects. And the 2021 Bipartisan Infrastructure Law includes $12 billion for capturing and storing carbon dioxide.
Together with other partners, Climeworks has applied for a slice…

CO2 Emissions May Be Starting To Plateau, Says Global Energy Watchdog
Many experts had feared the soaring price of gas could push countries back towards using coal, which has much higher carbon emissions. But renewable energy seems to have been a big beneficiary, as countries opted for solar and wind power, and encouraged the take-up of heat pumps and electric vehicles (EVs). A mild start to Europe’s winter also helped to save energy across the EU. Even a small increase in greenhouse gas emissions takes the world much further away from the path to net zero , the goal needed to limit global temperature rises to 1.5C above pre-industrial levels. Scientists have warned emissions need to fall by nearly half in this decade, if the world is to have a good chance of holding to the 1.5C limit.

A British Resident Emits 5x More CO2 Emissions Than The Level Recommended By The Paris Agreement
Despite the rising ecological awareness among the British public over the past few years, people often complain of not knowing…

Startups Capture CO2 and Store It In Concrete
Heirloom heats crushed limestone to release naturally absorbed CO2, then puts the CO2-starved rock on columns of huge trays, where they act like sponges, soaking up close to half their weight in the gas over three days. The rock is then heated to release the collected ambient carbon dioxide, and the cycle repeats. Canada’s CarbonCure, the concrete technology company, mixes CO2 with concrete ingredients, turning it into a mineral that strengthens the concrete, cutting the need for cement — the part of concrete with the biggest carbon footprint.

Climate change: Invest in technology that removes CO2 – report
Climate Startup Removes CO2 From the Air In Industry First
The cost of carbon dioxide removal and storage for these corporate clients is confidential and depends on what quantity of carbon dioxide the companies want to have removed and over what period of time. But the general price for carbon removal runs to several hundred dollars per ton. Individuals can also pay to Climeworks to remove carbon dioxide to offset their personal emissions.
Climeworks’ largest carbon dioxide removal facility is located in Iceland, where it partners with CarbFix, which stores the gas underground. CarbFix dissolves carbon dioxide in water then intermingles that mixture with basalt rock formations. Natural processes convert the material to solid carbonate minerals in about two years. In June, Climeworks announced it had begun construction of its second commercial-sized plant in Iceland that will capture and store 36,000 metric tons per year of carbon dioxide.

Measuring Virus Exposure Risk Using a CO2 Sensor While Traveling
TL;DR: big conference rooms: good, busses: bad, everything else: in between.
“Numbers alone do not effectively measure risk absolutely,” the page concludes. “You must combine numbers with logic and common sense. Airlines with good filtering systems are likely ok. But do aim the fans at you with maximum air flow…”
“Hallways and crowded coffee tables are where we need to worry the most. Unfortunately, the masking policy at IETF-115 was sort of backward: in the rooms the circulation was quite good, but in all my graphs you can see a spike as I wandered from one room to another, and this is where masking policies were more lax allowing participants to remove their masks.”
