Q: Are they actually committed to diversifying beyond oil and gas this time, or is this just a fresh round of greenwash?

Q: What is spurring the current round of acquisitions of renewables developers, power suppliers and EV infrastructure firms? Is it market pressures (e.g.... read more...


Lloyd’s of London divests from coal 25 years after first being advised to. What financial damage to their business has the delay entailed?

In a report entitled “Climate Change and The Insurance Industry”, the world’s largest insurance market was advised as follows in February 1993: “It would behove the industry to look very closely at where all capital is invested. Fossil-fuel-related operations should be eschewed, and solar energy and energy-efficiency projects favoured.” I remember that well. I wrote the report, and presented it at Lloyd’s of London, before a large audience of worried-looking reinsurers. Below is an extract from my book, The Carbon War, first published in 1999, describing the event, and a link to the original report.

Q: How do you feel about the developments at the One Planet Summit in Paris? Was it enough?

It wasn’t enough to hit the ultimate Paris Agreement targets, but enough to keep those targets in play. I very much enjoyed the flurry of financial-sector announcements at the summit. If the energy incumbency and its increasingly risk-burdened investors couldn’t see the writing on the wall... read more...


Rogue US can’t derail Bonn agenda as leaders keep the faith

The US was a marginal presence at a COP23 summit that kept the wind in the sails of global climate action, writes Jeremy Leggett in Recharge Magazine.

Busy executives in companies producing and using renewable energy may be wondering what to make of the increasingly detailed negotiations at the latest annual climate summit, held in Bonn over the last fortnight.

The chronicle which accompanies The Winning of The Carbon War

Act de Triumph

On Saturday December 12th, 2015, I witnessed something that nothing else in human history comes close to, in terms of scale and stakes. Every independent nation on Earth, 195 of them, adopted the world’s first universal agreement to fight an existential threat to civilisation and indeed life, as we know it, on the planet.
Going into the Paris Climate Summit, there were three possible outcome... read more...
