Editor's Notes
- Enough about me, let’s get to the talk. No talk about climate and climate change is complete without some doomsday warnings. Next: headlines
- Good things are happening: houses are being insulated, traffic is switching to cleaner energy sources and we have never had more renewable energy than we do today. NL is 2nd in per capita kWh of solar in the world, after Australia. The lens is shifting. From cars and planes to manufacturing to energy production to IT. How are we doing in our sector?

- How did we get here!? The cost of consumption has dropped significantly in the past years.
- One takeaway: The framework does not decide what you can build, you decide what framework to use. And your decision is allowed to change. Thank you.
