Research brief — green-living
| Field | Value |
|---|---|
| Slug | green-living |
Primary query / seo_intent | Put the household year on car, flights, power, and food |
| Template (A–G) | B |
| Evidence tier (1–3) | 1 |
| Audience (one line) | A household that already rinses the bin and suspects the bin is not the main job; plain kitchen-table talk, with the numbers named |
| AI authors credited | ChatGPT-4o (2024 draft), Grok 4.7 (rewrite) |
| Reviewer or checker (optional) | none; emissions medians are not a personal carbon audit or life advice about having children |
| Date | 2026-09-22 |
Near neighbor: sustainability is energy, transport, and materials as systems. This slug is the household year, ranked by tonnes.
1. Concentration claim (one sentence)
In a high-income household, climate impact concentrates in car travel, flying, home energy, and diet, while the advice people actually hear concentrates in recycling, bulbs, and small product swaps.
2. Hard anchors (2–5)
- Ivanova and colleagues, Environmental Research Letters, 2020. Meta-review of 53 studies. Medians: living car-free 2.0 tCO2eq per person per year; one less long return flight 1.7; renewable electricity 1.6; home refurbishment 0.9; vegan diet mean 0.9 and median 0.8. Car-free, a battery-electric car, and one less long flight each have a median above about 1.7. North American average footprint about 13.4 tCO2eq per person; Europe 7.5. Do not add overlapping medians into a personal total. https://iopscience.iop.org/article/10.1088/1748-9326/ab8589
- Wynes and Nicholas, Environmental Research Letters, 2017. High-impact set for developed countries: one fewer child 58.6 tCO2e/year (includes a share of descendants; easy to misuse), car-free 2.4, one roundtrip transatlantic flight 1.6, plant-based diet 0.8. Comprehensive recycling about four times less effective than the plant-based diet; lightbulbs about eight times less. In ten Canadian high school science textbooks, those high-impact actions were 4% of recommended actions. Government pages in the EU, US, Canada, and Australia also leaned on smaller actions. Tonne figures differ from Ivanova because the methods differ. https://iopscience.iop.org/article/10.1088/1748-9326/aa7541
2b. Field 80/20 examples (required — do not invent)
| Approx % claim | Field / context | Source (name, year, URL) or “adage — hedge” | Where it will sit in the article |
|---|---|---|---|
| High-impact actions were 4% of textbook recommendations | 10 Canadian high school science textbooks | Wynes and Nicholas 2017 — the 4% includes the contested "one fewer child" action | Opening section after the intro |
| Car-free median 2.0 t vs recycling "four times less" than a 0.8 t plant-based diet; bulbs "eight times less" | Developed-country lifestyle options | Ivanova 2020 for tonnes; Wynes 2017 for the recycling and bulb comparison. Not a measured 80/20. One action is not 80% of a 13.4 t North American average. | Lever table |
| Intro 20% / 80% | Household choices vs climate cost | Rule applied, then corrected: the papers show a steep gap, not a tidy 80/20 | Intro, then the first H2 |
3. Original observation (only-on-8020 seed)
A year sort: list last year's visible green acts beside the four large choices, and write the published median next to the large ones only. Rank by size. Do not add overlapping medians. The bin can stay on the list. It does not get to lead.
How it becomes a section in the article:
"Sort one year by size," with one Illustrative: pair of years.
4. Ignored majority (named)
Jar rinsing as the main project, bulb aisles, metal straws, tote bags, hotel toiletries, and product roundups. Worthy small acts. They are most of the advice and a thin slice of the tonnes.
5. Composite policy
| Scenario | Keep as Illustrative? | Cut instead? |
|---|---|---|
| Year A: full recycling, five bulbs, a tote, one long-haul flight, daily driving. Year B: same driving, no long-haul, renewable power contract | Yes | |
| A personal carbon total made by adding medians | Cut — say they overlap |
6. Vital few (draft list)
- Car miles, or a real shift off the car (car-free or a battery-electric car, without pretending they are the same).
- The next long flight.
- Home electricity and, when you can, the building.
- How much of the plate is ruminant meat and dairy, without turning the article into a diet plan.
7. Device budget reminder
Template B: one comparison table, caveats on overlap and on the child figure, one 8020 move, no step cadence, no viz.
7b. Viz & misreads (optional — default is omit)
D3 viz? none. Two papers do not earn a four-chart pack.
Misreads: Recycling does nothing (it does a small thing). One fewer child is the weekly chore (the 58.6 t figure counts descendants). An electric car is identical to no car. Adding the medians.
