Everyone's talking about electric vehicles and hydrogen. But what about the millions of diesel engines running RIGHT NOW - in trucks, mines, ships, and power plants - that aren't going anywhere anytime soon?

In this episode, I sit down with Brian Livingston, a 40-year chemical engineer who spent nearly two decades at Caterpillar's diesel engine division. Brian is the founder of Zelkam, where he helps diesel-intensive industries reduce fuel use and CO2 emissions by 5-7% using proven catalyst technology - with 100 to 400% ROI.

In this conversation, you'll learn:

• Why "wait for the perfect solution" is the most dangerous thing we can say about decarbonization

• How a catalyst actually changes the chemistry of diesel combustion

• Why the biggest sustainability wins are happening in industries most people never think about

• How cutting emissions and saving money can be the same move.

If you've ever wondered what practical, profitable decarbonization actually looks like, this is your episode. Head to https://nakedsustainability.com for more resources, episodes, and community support.
