“I hope the seminar went well, I couldn't make it sadly, hopefully next time.

“This is an interesting link from the guys just around your corner. While it is interesting and sad that the CO2 keeps rising, there is an important point in there saying this.

“Unless as a society we devise ways to remove CO2 directly from atmosphere, such as through negative emissions technologies, we're going to be stuck with a very slow decrease of CO2 from peak levels, and everybody will have to deal with the implications of global warming.

“Negative emissions technology, that's one we probably can't do without! any ideas? I know you too have faith that humanity will solve problems when motivated enough, so this is hope, I hope.

“All the best”

Eoin Treacy's view Thank you for your kind words and I look forward to welcoming you to another venue for The Chart Seminar in future. Negative carbon emission technology is a novel concept but its long-term success is likely to depend on its ability to perform economically.

A number of oil and gas drilling operations inject carbon dioxide as part of their enhanced recovery techniques. However, I suspect some of the more fervent green advocates would quibble that this merely displaces some of the carbon these operations would eventually produce. I'm afraid I do not know of an operation that literally removes carbon from the atmosphere that might provide an investment opportunity. If subscribers can suggest one I would be happy to mention it.
