My Theory of Change
As Iβve written previously, the world is facing a massive challenge β limiting warming below 1.5 degrees Celsius by cutting global emissions in half by 2030 and reaching net zero global emissions by 2050.
Today is an especially auspicious day toward reaching that goal as the USA announced its commitment to cut emissions in half by 2030 (β¦about time!)
When I heard the news this morning, I couldnβt help but wonder what my personal role in this journey will be. While I fundamentally believe in change at-scale through large institutions, I can appreciate the role that grass-roots initiatives play in summing up to a larger, collective movement.
So allow me to offer myself up for slaughterβ¦ π·
Am I practicing what I preach? Or am I part of the problem?
Introspection can be difficult without a guiding framework. So let's use the 5 sectors that encompass a majority of the global CO2 emissions to answer these questions:
What does good look like for personal climate behavior? andβ¦
What do I look like? Good, bad, or ugly
Power (~25% of emissions)
Context: The majority of global power emissions stem from coal power β roughly 2/3 of the total, with rates varying widely by region. Renewables are scaling quickly, but even renewables have some marginal footprint involved in the end-to-end mining, logistics, and construction.
What good looks like? This one is easy. Good looks like finding ways to source clean, low-carbon power and reducing consumption + increasing efficiency where possible. Fortunately, some utilities offer a clean-power opt-in program where you pay a little bit more, but ensure they are sourcing clean power to account for your footprint.
What do I look like? Starting off right. Iβve chosen to opt into MI Green Power through DTE for 100% clean electricity and have recently improved the insulation and efficiency of appliances at my home.
Keetonβs score: π good!
Industry (~25% of emissions)
Context: Industrial emissions stem largely from steel, cement, and petrochemicals production. These sectors are especially hard-to-abate given the high temperature requirements involved in the processes and inherent process emissions (the chemistry of cement literally creates CO2). Fossil fuels are just too dang good for these use cases today.
What good looks like? This one is a bit harder given the institutional scale of emitters, but Iβd propose that βgoodβ here is limiting consumption where possible and practicing the 3 Rs: reduce, reuse, recycle.
What do I look like? Given that reducing and reusing come first, Iβd admit that I am a relatively heavy consumer of goods. However, I try and recycle whenever I can, have a compost bin at home thanks to my significant other, and generally avoid building massive concrete and steel structures in my back yardβ¦
Keetonβs score: π decentβ¦
Transport (~20% of emissions)
Context: This sector is perhaps the most straight-forward to understand. Emissions stem mostly from road transportation (about a 50-50 split between commercial and passenger vehicles) with about 1/4 of the total emissions stemming from air and marine travel.
What good looks like? Electrification! While the net benefit of electric vehicles is not absolute due to a carbon-intensive grid, switching to electric vehicles when affordable is a long-term decision that will only get better as the grid gets cleaner. Additionally, limiting air travel when possible, riding on public transportation, and walking / biking to local destinations is best practice.
What do I look like? Not greatβ¦ Iβve given up the weekly air-travel from my consulting days, but I still drive a gas-powered car (I love driving a stick shiftβ¦) and I donβt use public transportation nearly as much as I should.
Keetonβs score: π₯ Uglyβ¦
Land-use & Agriculture (~15% of emissions)
Context: The majority of emissions attributed to land use and agriculture globally come from deforestation, agricultural methane1 emissions from animals (literally cows burping), crops (decomposition of rice), and waste or landfill emissions.
What good looks like? Given the above, practicing what you preach means living in a relatively small footprint dwelling, with lots of trees or plants nearby, supporting strong local and state parks, and limiting consumption of meat.
What do I look like? I definitely support Michigan state and local parks and have trees and shrubs around my house β but that house is single-family rather than a dense, multi-unit option β and I fail badly on the meat front. I love a good steak. And I indulge too frequently. (no thanks to the BBQ place across the street).
Keetonβs score: π Bad.
Buildings (~10% of emissions)
Context: Cooking and heating homes make up the bulk of the carbon footprint attributed to the building sector if we count the electricity usage associated with buildings in the βPowerβ category.
What good looks like? Given the above, good would look like electrical appliances β stove, water heater, laundry units β and a bi-directional heat-pump to cool and heat your house. (remember: electrify everything!)
What do I look like? Going the wrong direction β donβt look now but I just replaced my electrical range with a gas range. As far as heating goes, heat-pumps are not as efficient today as theyβd need to be to operate in cold weatherβ¦ so it is tough to make a replacement there yet. As far as appliances go, the pleasure of cooking on a gas stove is not one that Iβve been willing to give up to date.
Keetonβs score: π₯ Uglyβ¦
Putting one foot in front of the other π΅
In summary: πππ₯ππ₯
Iβve got a long way to go.
Letβs acknowledge that this is really difficult. I think about climate change 40+ hours a week in my day job, but I score poorly on the grassroots / at-home initiatives front.
Behaviors donβt change overnight, but I am a firm believer in putting one foot in front of the otherβ¦ soon weβll be walking out the door!
Iβd invite you all to take a moment and perform the same exercise on Earth Day β I am confident the vast majority of you will score better than I did and inspire me further!
Until next timeβ¦
Methane is another greenhouse gas that has a higher relative impact than CO2 (roughly 20-80x depending on the time scale you talk about). If you want to learn more, Iβd encourage you to look into the global warming potential for different gases β a good source found here: https://www.epa.gov/ghgemissions/understanding-global-warming-potentials
πππ₯ππ, my pros include residential solar, reuse/recycle, and composting. Could do better for sure!
We can only take care of the future by raking care of the present.
