The BBC reports on a new Oxford study that finds switching from fossil fuels to renewable energy could save the world as much as $12tn (£10.2tn) by 2050. The report said it was wrong and pessimistic to claim that moving quickly towards cleaner energy sources was expensive. "Our latest research shows scaling-up key green technologies will continue to drive their costs down, and the faster we go, the more we will save," said Dr Rupert Way, the report's lead author from the Smith School of Enterprise and the Environment.

The US’s new inflation-busting bill, with $369bn for clean energy, is the largest US investment in climate ever. It is also, according to our research, the largest national climate investment in history anywhere. Let that sink in for a moment.

This funding will certainly speed renewable energy deployment and green job creation in the US. However, the bill’s investments are so large that they are likely to influence global prices too, and impact the energy transition in other countries in real, tangible ways.

Canadian publication The Walrus explores the UK's climate policies and approach. With comment from Professor Sam Fankhauser, who sat on the UK's Climate Change Committee for its first eight years and now teaches climate policy at Oxford University.

Brian O’Callaghan, lead researcher at the Smith School's Economic Recovery Project, provided expert commentary on the US Inflation Reduction Act 2022 - a transformative new climate bill. He noted, among other points, that the bill has nothing to fulfill America’s broken promise of billions of dollars in climate aid for poor nations.

The i newspaper speaks to Greg Jackson, founder and CEO of Octopus Energy, and references recent research on energy security from the Oxford Smith School. “The choices made now will determine the course of the next 10 years – in terms of energy security, cost and our future environment,” said Professor Sam Fankhauser, Dr Steve Smith and Dr Anupama Sen. “More renewables actually raises security and lowers cost.”

As thousands of people in Yorkshire, Lincolnshire and the north-east were left without power after transmission equipment overheated, Dr Sam Fankhauser, professor of climate economics at the University of Oxford said the heat was “a stark reminder of … the urgent need to decrease global carbon emissions."

Researchers from the University of Oxford institution parsed more than 900 papers on the economic characteristics of green spending before concluding there is "strong evidence" that green investments outperform fossil fuel investments in terms of job creation.
