greenhouse gas emissions

Are you listening? Good.

A carbon dioxide filtering device that can capture carbon dioxide from the air at just 400 parts per million has been hailed as a “revolutionary” instrument for tackling our climate crisis.

Sahag Voskian and T. Alan Hatton, chemical engineers at MIT, developed the method, which captures CO2 by passing air through special charged plates.

Carbon dioxide from the gas intake reacts with the electrodes in the device. Each electrode is coated with a carbon nanotubes and a polyanthraquinone compound. The device acts sort of like a battery, and as it charges, it absorbs carbon dioxide passing over the electrodes. As it discharges, it releases the greenhouse gas it has collected.

The carbon dioxide it releases during the discharge can be recycled to feed greenhouse plants, or even used in carbonated beverages.

Dr. Voskian said, “All of this is at ambient conditions — there’s no need for thermal, pressure, or chemical input. It’s just these very thin sheets, with both surfaces active, that can be stacked in a box and connected to a source of electricity.”

The biggest advantage to this way of filtering is the low energy cost: one gigajoule of energy for every ton of carbon dioxide captured. Compare that to the 1-10 gigajoules (depending on the concentration of CO2 taken in) used by alternative methods. Plus, if to expand the systems capacity, they only need to add more electrodes!

The study describing the new system was published in the journal Energy and Environmental Science.

The scientists have even created a company called Verdox that plans to build a plant to scale the process up for commercial use.

Cleaner air with lower energy. There’s a real future for that.

Many people and governments and companies around the world are doing their best to mitigate some of the effects their lives and business dealings have on the planet, so that hopefully we can have a future that doesn’t include a complete apocalypse and the extinction of human beings.

These 20 companies, though, appear to not give a rat’s a** how much they harm future generations, as long as they’re still making the big bucks.

According to the Climate Accountability Institute, a handful of oil, gas, and coal companies are responsible for 480 billion tonnes of carbon dioxide and energy-related methane pumped into Earth’s atmosphere since 1965 – that’s 35% of all greenhouse gas emissions since then.

The report also states that half of all greenhouse gas emissions in recorded history have been released into the atmosphere since 1990, with 1.35 trillion tonnes of carbon dioxide (or equivalent GHGs) emitted since 1965.

The CAI had this to say about their findings in a recent press release:

“Although global consumers from individuals to corporations are the ultimate emitters of carbon dioxide, we focus on the fossil fuel companies that, in our view, have produced and marketed the carbon fuels to billions of consumers with the knowledge that their use as intended will worsen the climate crisis.”

Here’s a list, from worst to…less worse.

20. Saudi Aramco (Saudi Arabia) — 4.38 percent
19. Chevron (USA) — 3.2 percent
18. Gazprom (Russia) — 3.19 percent
17. ExxonMobile (USA) — 3.09 percent
16. National Iranian Oil Co. (Iran) — 2.63 percent
15. BP (UK) — 2.51 percent
14. Royal Dutch Shell (The Netherlands) — 2.36 percent
13. Coal India (India) — 1.71 percent
12. Pemex (Mexico) — 1.67 percent
11. Petroleos de Venezuela (Venezuela) — 1.16 percent
10. PetroChina/China Natl Petroleum (China) — 1.15 percent
9. Peabody Energy (USA) — 1.14 percent
8. ConocoPhillips (USA) — 1.12 percent
7. Abu Dhabi (UAE) — 1.01 percent
6. Kuwait Petroleum Corp (Kuwait) — 1 percent
5. Iraq National Oil Co. (Iraq) — 0.93 percent
4. Total SA (France) — 0.91 percent
3. Sonatrach (Algeria) — 0.91 percent
2. BHP Billiton (Australia) — 0.72 percent
1. Petrobras (Brazil) — 0.64 percent

If we hope to achieve the goals set by the Paris Climate Change Agreement in 2017, all of these companies would have to recognize their current levels as a “peak” and immediately begin to taper them. The report says that these fossil fuel giants, and others like them, have “a significant moral, financial, and legal responsibility to help curtail and compensate for the runaway effects of climate change.”

It’s time for people to stop plowing ahead like horses plodding a field with blinders on, eyes on nothing but the row of money to be reaped ahead. If the world wants to survive long enough to leave something other than smoking ashes for our kids, the time is nigh to stop, look around, and start to take several million steps back.
