Hence terms like “gigawatt” or “gigahertz.” Thus, a gigaton is equivalent toa billion metric tons. Are in a ton? Ton, unit of weight in the avoirdupois system equal to2,000 pounds (907.18 kg)in the United States (the short ton) and 2,240 pounds (1,016.05 kg) in Britain (the...
Mark Patel:I am a big fan of what we might be able to do in the ocean. The ocean is our biggest carbon sink on Earth. And the reason that I am so interested in the ocean is because of its scale and its potential for scaling removal approaches. If we ...
“The concept of CO2 removal is, if we can’t entirely cut out the activities that are causing emissions, then let’s instead find other mechanisms in which we can remove carbon dioxide, or gases that are equivalent to carbon dioxide … and capture it, contain it, store it, or ...
just capturing and sequestering one gigaton is equivalent to running the entire petroleum industry in reverse gear. This effort is going to require a collective coordinated effort greater than what it took to win World War II. The bottom line is what we’re doing today is not enough. We’re...
Figure 1:Current position on cutting global emissions to “safe” levels Obviously the world is going to have to reverse course in a hurry if it is to have any chance of keeping warming below the 2C danger threshold. What are the chances that it can? Let’s look at which countries the...
So, there’s not much reason to invest in it because there isn’t much demand. That’s the cycle that we need to break if we’re going to reach the gigaton scale of negative emissions that we know is going to be important to—along with reduci...
they are home to more than 40 percent of the global smallholder farmer population and generate about one metric gigaton of GHG emissions from agriculture.12The results highlight not only areas of commonality across smallholder systems but also the importance of a differentiated approach by country an...
The majority of emissions in this sector originate from fugitive coal-bed methane that is released during coal mining (1.5 to 4.6 gigatons), mainly at underground operations.7 Power consumption in the mining industry contributes 0.4 gigaton of CO2e. Further down the...
The trend toward greater electricity consumption, combined with the projected carbon intensity of the national power supply, contributes to the 1.2-gigaton increase in emissions associated with buildings. Important abatement oppo...
that decarbonization is the most critical response to climate change, but McKinsey’s research shows that decarbonization alone may not be enough. The report says carbon dioxide removal, or CDR, could play a vital role in combatting hard-to-abate emissions. What are these hard-to-...
