Unrecord greenhouse gas data threatens Paris accord

Potent, climate-warming gases are being emitted into the atmosphere but are not being recorded in official inventories, a BBC investigation has found.

Air monitors in Switzerland have detected large quantities of one gas coming from a location in Italy.

However, the Italian submission to the UN records just a tiny amount of the substance being emitted.

Levels of some emissions from India and China are so uncertain that experts say their records are plus or minus 100%.

These flaws posed a bigger threat to the Paris climate agreement than US President Donald Trump's intention to withdraw, researchers told BBC Radio 4's Counting Carbon programme.
