I am currently thinking about carbon from three main approaches:

My  personal carbon footprint
Current actions: create a carbon footprint budget spreadsheet similar to retirement spreadsheet to update annually. Identify carbon offsets(NW Natural offsets look good, Pacific Power less clearly) and renewable energy that I’m comfortable supporting. Keep trying to consume as little as possible. Share offsets and carbon footprint spreadsheet on Greenwriters.

Policy changes to capture the cost of carbon
Current actions: email friends and contacts in politics to ask them about best ways to support elected official actions. Then start doing these actions and share on Greenwriters.

Corporations and other organizations
My action: keep working on personal “divestment” and active investment and sharing what I learn on Greenwriters.
