Kind: research · Impact: medium

## In brief

- Researchers used mobile phone location data to study patterns in carbon emissions.
- The article notes that conventional emission inventories lag reality by months, and that satellite-based inversions have their own trade-offs.
- The study was prompted by COVID-19 lockdowns in early 2020, which cut emissions sharply and exposed gaps in tracking instruments.

## Why it matters

Faster, more granular emissions estimates could help scientists and policymakers see changes in emissions sooner than conventional inventories allow.

## Timeline

- 2020-01-01: COVID-19 lockdowns cause carbon emissions to plummet in early 2020
