Guides: the questions people actually ask
Every guide answers one real question with named sources and no hedging filler — the same questions the in-app Ask Sustainability screen gets every day, written down properly.
Glass vs plastic: which is actually better?
Glass feels premium and plastic feels guilty — but for single-use bottles the carbon math flips the story. When each one wins, with the numbers named.
Paper vs plastic bags: the reuse math that settles it
A paper bag must be reused three times to beat a single-use plastic bag on climate impact, per the UK Environment Agency. The best bag is the one you own.
Is organic worth it?
Organic is a verified farming standard, not a health halo. Where the seal earns its price premium, where it matters less, and which aisles to spend it on.
What "carbon neutral" actually means
Carbon neutral means emissions were offset on paper, not eliminated. What the label really promises, why offsets keep failing audits, and what to trust.
Are electric cars better for the environment?
An EV beats a gasoline car on lifetime emissions in every market the ICCT studied, even on today’s grids. The battery debt and the payback, explained.
Is bamboo really sustainable?
Bamboo the plant is a sprinter; bamboo the fabric is usually rayon from a chemical bath. Which bamboo products earn the hype — and which got brands fined.

What is a carbon footprint?
A carbon footprint is every greenhouse gas a product or person causes, counted as CO2e. The averages, the beef-to-peas spread, and who coined the term.

Transport is only about 6% of food’s emissions, per Our World in Data — what you eat matters far more than where it came from. When local truly helps.
