>But there's probably no business there.

Because God forbid we try and preserve the vast majority of life on earth instead of pursuing generating millions of dollars of profit every month.

The vast majority of human beings haven't put 1 minute of thought into global warming, in fact it wouldn't surprise me if there were billions of human beings walking around today that have never even heard of global warming or climate change, aside from noticing each year getting hotter and hotter and weather getting a little more extreme.

We don't need startups taking a 20% vig via a subscription service for a feel-good "I did my part by giving money" company. We need to present the facts, as unbiased as possible, to the masses and get people to start questioning the topic. We need people to start going "oh, wow, we did that?" we need them to start thinking "well how can I minimize my impact myself".

More than a third of the world's population lives on less than $2 a day [1]. Do you think that 2.5 billion people can afford to scrape together even $2 a month to offset the CO2 from their cooking?

The median annual household income worldwide is $9,733,[2], do you think that families can afford to pay $10-20 a head worldwide? Do you think that 1/3 of the world's population can realistically afford that? Do you think by the time that Wren backs out 20%, then the non-profits/NGOs/companies they turn around and give the money to backs out their operating costs, that that amount of money (probably 50% or less of the original contribution) will make even a 10% reduction in last year's CO2 emissions and that it will not only be able to keep pace with the increase, but also continue to increase to the point of getting us not just carbon neutral, but removing 10-2 gigatons more than we produce each year to try and restore us to levels of even the 1980s in any reasonable amount of time?

I don't. I think this company is just going to be away for those individuals with a little disposable income, that believe in climate change and feel guilty about driving their car and flying everywhere for vacations, to buy themselves a little 'feel good' or a little peace of mind. Most will probably think they're really making a difference and that all will be fine.

Even if Wren manages to generate 5 billion dollars a month, and ends passing 4.95 billion down the chain, it's unlikely to even result in sequestering 10% of last year's levels annually. Seriously, run the numbers yourself, everyone that's going to downvote this comment like you are my others, RUN THE NUMBERS please. You'll see that this isn't going to be the solution, nor is it likely to lead to one. It is the wrong approach to the problem as is.

This is Silicon Valley being clueless and/or overly optimistic as usual with these sorts of markets/challenges, just like YC wanting to turn half of the Sahara into shallow algal pools (which would result in the rainforest losing massive amounts of fertilization and cause a potentially catastrophic change in global weather patterns, not to mention require more electricity than the plant currently produces).
