Enhanced rock weathering is an approach to carbon removal based on natural processes. We took stock of the growing body of research results and found that carbon removal estimates are highly variable – there is still a lot to learn!

Cricket farms lose on average 50% of their production! This blew my mind. There is so much room for improvement in the insect farming sector. Highly overlooked, probably because most of us feel uncomfortable about it.

Just 11% of VC funding in Europe went to startups led by women in 2023. You wonder why? ♂️ VC is the ultimate boys club

πŸ’‘ One thing few people know: Refrigeration and HVAC are responsible for 10% of global CO2 emissions. β€’ Cooling uses fossil fuel β€’ Refrigerant gases - fluorocarbons - are powerful greenhouse gases β€’ Significant perishable goods waste because of refrigeration disruptions

1/ Isometric recently received conditional endorsement by ICROA as an accredited carbon crediting program. Isometric is the first registry to receive endorsement against the newest version of ICROA’s guidelines, which were recently updated with more stringent requirements.

βœ”οΈ So many people invest in the stock market. ❌ Almost no one invests in startups. I don't understand this. 1) Startup investing yields better returns. 2) Barriers to angel investing are lower than ever. 3) It's a lot of fun and you meet incredible people!

The number of Enhanced Rock Weathering projects that launched in the past few months is impressive! Not surprising, given it's arguably one of the cheapest and most scalable carbon removal technologies. I've put together this ERW ecosystem map πŸ‘‡ colinrebel.com/40-enhanced-ro…

"C players FIRE A players" Don't know if someone has ever experienced this? A players certainly leave teams of C player. When standards and ambition are low, A players quickly notice and start seeking better opportunities, better places to thrive.

AI-powered software, computer vision and machine learning to replace cumbersome, costly and unreliable manual checks in insect farms. This is one of the less-expected AI applications I've come across so far! Any other weird stuff?

Fact: Venture Capital beats the S&P 500. AngelList claims the platform has generated 26.5% per year for investors dating back to 2013! I believe everyone should have 5% to 15% of their personal wealth invested in startups and private companies. Why isn't everyone doing it?

Ok quick story time (don’t blame me, Danielle started it) Valar is the first company I’ve raised venture money for. I lived in a town of 22k in north Idaho with no close friends or family who were founders, VCs, or really in tech in general. No college network (I skipped

Don't put all your eggs in one basket. Investing in startups introduces you to a new asset class and is a great diversification opportunity. But few investors explore the private markets. Why? I love how the VC fund Loyal measures its performance against other asset classes!

If I launched a carbon removal startup today, it would certainly be an Enhanced Rock Weathering one. β€’ The technology is ready β€’ The infrastructure is ready β€’ It has the potential to remove 2 billion tonnes of CO2 per year β€’ The cobenefits for the farmers are huge (yields)

3 things I love about investing in climate tech startups: 1. Voting with my money; making an impact on issues I care about. 2. Working with founders who dream big and push technological frontiers. 3. Staying up to date with the latest trends in climate innovation. Join the fun!
