Meat alternatives are greener than meat, right? Well, let’s look at the data. To try everything Brilliant has to offer for free for a full 30 days, visit https://www.brilliant.org/simonclark.

ERRATUM: At 8:58 we show tempeh (spelled as tempei) as having a carbon intensity of 0.5kg CO2e / gram of protein. This is incorrect, it should be 2.5kg CO2e / gram of protein.

We often hear that meat alternatives are better for the environment. To test that, I look at the carbon footprint, land use, and other environmental metrics of the major meat substitutes and compared them to beef, chicken, pork, and mutton. The result may surprise you!

How green are meat substitutes? Is fake meat actually good for the environment? Do tofu, beyond meat burgers, quorn, and soy protein have lower carbon emissions than chicken, beef, and pork? In this video I look through the literature and talk to a world expert on the intersection between food and climate.

How airlines can halve their climate impact

See how much you can rinse Nebula in 3 days: https://go.nebula.tv/simonclark

For many of us in the West, aviation is a huge chunk of our climate impact, and most of the impact of any given flight doesn’t even come from its carbon emissions. Fortunately, new analysis and field tests indicate that this impact can be mitigated quickly, cheaply, and safely.

If you wanted a message to send to your airline, perhaps something like the following?
“Hello [AIRLINE], I am one of your customers. Do you incorporate contrail avoidance into your flight routing or are you planning to take part in one of the many trials in contrail avoidance? Here’s a website explaining how easy and effective it is: contrails.org”.
