Throughout 2024, two of the bloggers that I regularly follow reported on their attempts to follow the Rule of 5. What’s that, you ask?

The vast overproduction of clothing by the fashion industry is responsible for almost 10% of greenhouse gas emissions worldwide. In 2022, Berlin’s Hot or Cool Institute determined that in order to meet the internationally agreed upon goal of limiting global warming to 1.5ºC, we should purchase no more than 5 new garments a year. That led to the Rule of 5.

Here’s how it works:

1. Buy no more than 5 new items during the calendar year.
2. Socks, tights, underwear, and nightclothes don’t count.
3. Shoes, boots, and accessories DO count.
4. Second-hand shopping is allowed, but don’t go overboard.
5. Gifts count. (This is to prevent cheating by having someone else buy for you!)

I haven’t actually participated in the Rule of 5, but looking back I discovered that I inadvertently met the goal in 2023 before I’d even heard of it! I didn’t do as well last year, buying 8 items that would count. The bloggers that I follow didn’t meet the goal either, but they both agreed that trying had changed their shopping habits and made them much more intentional about what they bought. I’d consider that success.

Although the idea has merit, I haven’t committed to the Rule of 5 for this year either. I will continue to keep track of my purchases though and see how close I come. So far, 7 weeks into the year, I’ve only purchased one item, a colourful necklace that cost less than $10 at a tiny shop in the bus station in Xalapa, Mexico. The anchor and cross symbols are very meaningful to me, but if I’d been committed to the Rule of 5, I probably wouldn’t have bought it.

So, what do you think? Would you ever try the Rule of 5? Do you think you could do it?
