Sustainability performance 2025
So how did my life impact sustainability during the last year? I would rate my performance as again improved, and again insufficient. On the plus side, many advances – In the last 12 months, I have not flown on an airplane. The last time I could say this was in perhaps 1982 when I was still in university. Lots of working remotely, lots of train travel. I would say that my automobile usage is down also: based on gasoline purchases, about 10%. The biggest impact in direct emissions is likely a change from 2 cycle lawn equipment to electric. Those little weedwackers spew an emission stream that is much much worse than automobiles. My consumerism level also continues to decline, a few clothing purchases, but higher quality more durable items and informed decisions about local vs. “container shipped” product purchases. On the home heating front, installation of a high-efficient fireplace insert has resulted in a dramatic reduction in both wood consumption (burning) and heating oil use. Also multiple “reusage” of things is something I continue to do.
On the negative side, I am still playing golf, which is a net environmental negative. And while I am using the car “less” relative to the past years, the automobile is a machine that really hurts the planet – especially as there are so very many of them.
One of my concerns is that I have some hypocrisy here; there is an unattributed Greek proverb: “First secure an independent income, then practice virtue”. I am older, my career is well established and I have a broad global network of people I have long-term relationships with. I think a younger person, just starting their professional career may need to travel and see people and things in-person to be successful and have an impact. But, I can only control what I do…
So generally, what do I think of humankind’s sustainability potential? Marginally improved as compared to a year ago. My general outlook remains quite negative – consumerism (read human greed) is causing us to use the earth’s resources much faster than they can be replaced, and as a society, our thinking and planning remain very short term; future generations are unimportant to us. Plus, our historical tendency to war over limited resources remains in force. The one improvement I do see is in population. The human population growth rate continues to decline https://ourworldindata.org/grapher/population-growth-rates . My opinion is that we will need to get to a population of about 5 billion people to live sustainably long term, but the critical factor is what is/are those lives? Certainly not “private jetting” to Burning Man cause someone cool will be there… I suggest reading the work of Joel Cohen, particularly ” How many people can the Earth support?” available on ResearchGate https://www.researchgate.net/publication/353942585_How_many_people_can_the_Earth_support.
I will try to do better.
