A California startup using rocks to soak up carbon dioxide from the air has teamed up with a Canadian company to mineralize the gas in concrete, a technological tie-up that is a first and they say could provide a model for fighting climate change globally.

Uber and Lyft, the two biggest ride-sharing companies in the New York City area have been told by Eric Adams, the city’s mayor, to clean up their fleet by 2030.

The PhotonAssay™ technology was developed by #CSIRO. It delivers faster, safer, more accurate, and environmentally friendly analysis of gold for the minerals industry.

Plans for the first electric airliner took a step forward as Swedish startup Heart Aerospace AB swelled its design to 30 seats, announced a factory site and won investment from Saab AB, maker of the Gripen fighter.

California regulators will vote to put in place a sweeping plan to restrict and ultimately ban the sale of gasoline-powered cars, state officials said, a move that the state’s governor described as the beginning of the end for the internal combustion engine.

“Mass uptake of e-bikes” will also lead to “a significant early contribution” in reducing transport emissions, while asking much less of the power grid, the study found. E-bikes are a double boon to the grid because their home chargers run on existing circuits and draw “relatively low power (500 watts to 1400 watts).”

Australia has no clear strategy to decarbonise transport. That’s a problem, because without a plan, our take-up of clean technologies like electric cars, trucks and buses is slow.

Carbon capture can help both reduce the carbon footprint of certain industries and, uniquely, remove legacy carbon from the atmosphere; even the most ambitious emission-reduction scenarios maintain a share of fossil fuels usage, suggesting carbon capture solutions are needed to achieve full decarbonisation.

Qantas on Thursday pledged to lower its net carbon emissions by 25 per cent from 2019 levels by the end of this decade, setting a new target en route to its existing ambition of hitting net-zero by 2050.

Frustrated by a lack of reliable and credible market supply of carbon offsets, Telstra says it will instead bolster its own stocks by planting 240 hectares of land in northern NSW to store greenhouse gas emissions.

Hysata, an Australian hydrogen technology company, has developed an ultra-high efficiency electrolyser, a major breakthrough in the industry’s attempt to reach the commercialisation milestone of producing a kilogram of hydrogen for under $2.

To compete with fossil fuels, you need to "make renewables predictable," says Piconi, founder of Energy Vault, which means storing excess energy and being able to dispatch it when required.
