The aircraft manufacturer Embraer saw its greenhouse gas emissions from operations and electricity use (Scopes 1 and 2 of the Greenhouse Gas Protocol) fall by 62% over a five-year period, despite increasing production as it delivered 57% more aircraft to customers over this period.

Competitors such as US-based Boeing and Canadian-owned Bombardier also saw their emissions decrease by 2% and 27% respectively between 2005 and 2009, while emissions at European manufacturer EADS rose by over 7%. Embraer's performance was mainly driven by a 94% decrease in electricity use, whereas Boeing's was achieved by reducing fuel use by 40%, although its electricity consumption increased proportionally by 46%.

The table and chart below show the greenhouse gas emissions, measured as carbon dioxide equivalents (CO₂e), produced by each manufacturer per aircraft delivered in both 2005 and 2009. Emissions per aircraft give an indication of the company's environmental efficiency.
