Reader Q&A explores whether filling all car tyres with CO2 could meaningfully reduce atmospheric carbon
Executive summary: The Guardian published a reader Q&A asking if filling every car tyre with CO2 would cut atmospheric carbon significantly. The question surfaces public appetite for simple climate solutions and raises feasibility, scale and industrial implications for tyre makers and CO2 markets.
Who is involved: Guardian readers and editorial team; implicitly tyre manufacturers and CO2 market participants.
Likely next: Further expert analysis, possible pilot projects or dismissal by scientists; may stimulate debate in automotive and climate‑policy circles.
The Guardian’s reader‑driven column poses a speculative climate‑mitigation idea: using the vast volume of vehicle tyres as a reservoir for captured CO2. While the concept highlights public interest in low‑cost carbon removal, experts note that the total CO2 that could be stored in tyres is tiny compared with annual emissions, and practical challenges such as tyre purity, valve design and CO2 supply remain unresolved. The piece therefore serves as a catalyst for discussion rather than a near‑term policy proposal.
