Trees are still the most effective and affordable way to sequester carbon. On average, a single tree sequesters 50 lbs of carbon dioxide a year. Over the average 40-year lifespan of most urban trees, that’s roughly 1 ton of carbon dioxide per tree. With an estimated 5.5 billion trees in urban areas alone, you get 137.5 million tons of carbon sequestered from the atmosphere from urban forests every single year and 5.5 billion tons over 40 years — a small investment with a big ROI.

Sense-induced energy reductions will vary from house-to-house and depend on a variety of factors, including energy provider (and their fuel mix), whether the home has solar and a battery, and how many appliances are gas-powered vs. electricity-powered.

Carbon markets are an opening for corporate enterprise and a distraction from real reduction strategies. In the last few months, I've learned of and compiled a growing list of carbon market APIs and marketplaces that are well-intentioned, but signal opportunities to keep business as usual.

CMAP continues to command a growing space in my free thought. If you've read some of my past calls to climate action, you'll quickly realize that I advocate for individual climate advocacy as a groundswell for major climate action. In the past few years, after learning more about climate change and witnessing very real present-day impacts, I was determined to find my own path to create change.

Although Oakland's approach to urban data is both underwhelming and ill-equipped, it presents an opportunity to drastically improve its approach from intercept surveys, OPD crash data, and maintenance interviews. Lightweight automated tracking and sensor-based solutions present an opportunity to collect de-personalized movement and count data that is far more accurate and functionally cheaper than people.

Walkability may not be top of mind for the average Portland tourist like it is in New York City, but it's a clear benefit if you're staying on the Eastside of the river. Nearly every neighborhood on the Eastside of Portland features a wonderful new restaurant or neighborhood institution that anchors public thoroughfare — featuring a combination of lively walking culture with convenient corner markets and small local businesses cozily mixed in with commercial complexes, light industrial, and modern one-plus-five mid-rise apartments.

In 2019, 134 pedestrians were killed by drivers while walking in Los Angeles, a bustling city with a population of just under 4 million. By comparison, the Netherlands reported a total of 49 pedestrian road fatalities in 2019 in a population of more than 17 million. While any number of deaths is too much by any measure of success, it's safe to conclude that the Dutch are doing something far more effective than what's happening in one of the largest cities in the United States.
