Dominic Cummings authorises £100m to suck CO2 out of the sky

Daily Mail - Science & tech

Boris Johnson's chief adviser Dominic Cummings is backing a scheme to suck carbon dioxide out of the air using technology first used on World War Two submarines. The PM's advisor wants to spend £100 million on'direct air capture' (DAC) machines, which consist of a stack of metal'air scrubbers' that use a chemical solution to remove the CO2 from the atmosphere. The CO2-laden solution is then stored underground, reducing the amount of the greenhouse gas that reaches the atmosphere. The gas can be permanently stored in deep geological formations, or used to make fuels, chemicals, building materials and other products. The tech could help to offset emissions from energy-intensive sectors that are difficult to decarbonise, such as transport and aviation. And because the CO2 is being permanently removed from the atmosphere, the technology supports the UK's net zero emissions target for 2050.

Could the UK become 'carbon neutral' in just 30 years?

Daily Mail - Science & tech

Plans for the UK to become'carbon' neutral by 2050 have been released by Theresa May's government, but experts are concerned over how the proposals will work. The new report commits to ensuring that the emissions generated by the UK are offset by removing the same amount of carbon from the atmosphere. There are two main ways this can be achieved - by planting more trees and by installing'carbon capture' technology at the source of the pollution. Some critics are worried that this first option will be used by the government to export it's carbon offsetting to other countries. International carbon credits let nations continue emitting carbon while paying for trees to be planted elsewhere, balancing out their emissions.

Apple invests in world's largest onshore wind turbines in bid to become carbon neutral by 2030

Daily Mail - Science & tech

Apple is investing in the construction of two of the world's largest onshore wind turbines, as part of its effort to become '100 per cent carbon neutral' by 2030. The 650-foot turbines, located near the Danish town of Esbjerg, are expected to produce 62 gigawatt hours each year -- enough to power almost 20,000 homes. The electricity produced at Esbjerg will be used to power Apple's 500,000-square-foot data center in Viborg, with all surplus energy going into the Danish grid. It will also act as a test site for powerful offshore wind turbines, the company said. Apple did not say how much it was investing in the project, which is being developed in partnership with European Energy.

Efforts to suck carbon from air must be ramped up

Daily Mail - Science & tech

The nation needs to ramp up efforts to suck heat-trapping gases out of the air to fight climate change, a new U.S. report said. The report Wednesday from the National Academy of Sciences says technology to do so has gotten better, and climate change is worsening. By mid-century, the world needs to be removing about 10 billion metric tons of carbon dioxide out of the air each year. This illustration provided by Carbon Engineering in October 2018 shows one of the designs of the company's air contactor assemblies to remove carbon dioxide from the atmosphere Last year the world put nearly 37 billion metric tons of carbon dioxide into the air, and emissions have been rising. Steve Pacala, Princeton University biologist and chair of the panel, said in an interview that having ways to remove heat-trapping gases from the atmosphere would make the job of tackling climate change'much easier.'

Apple to be '100% carbon neutral' across business by 2030

Daily Mail - Science & tech

Tech giant Apple has said it will be 100 per cent carbon neutral by 2030 by offsetting emissions of the greenhouse gas from its operations. The iPhone maker said it will have a net zero carbon footprint in 10 years across its entire business, including its manufacturing supply chain. Apple is already carbon neutral for its global corporate operations, such as its offices and data centres, which are powered by 100 per cent renewable energy. But this new commitment means every Apple device sold, including iPhones and Mac computers, will have net zero climate impact, according to the company. Apple's most recent environmental report, covering the fiscal year 2018, put its carbon footprint at 25.2 million tons.
