Earthwatch · now part of EarthConvergence

Earthwatchwhat a planting or a panel is worth, roughly

Earthwatch began as a separate environmental-impact dashboard. It now lives here, as part of EarthConvergence: the study of other species and the watch on the places they live belong on the same site. What carries over is its impact estimator — the same arithmetic, running in your browser, with every coefficient printed.

Impact estimator

× 0.0218 t CO₂ each

× 0.137 t CO₂ per m²

× 0.000475 t CO₂ per kWh

Estimated CO₂ offset

4.50 tonnes

From trees
100 × 0.0218 = 2.180 t
From solar
10.0 m² × 0.137 = 1.370 t
From energy
2,000 kWh × 0.000475 = 0.950 t

The working

Coefficients used

Per tree
0.0218 t CO₂
Per m² of solar
0.137 t CO₂
Per kWh
0.000475 t CO₂ (a grid-average factor)
