The 1.8 million two-stroke vehicles in the Philippines produce the pollution equivalent of 5 billion automobiles. 1.3 million taxi drivers & millions of working class Filipinos rely on them for income/transportation respectively. Our retrofit dramatically reduces emissions: carbon monoxide 76%, carbon dioxide 35%, & hydrocarbon 89%. In addition, fuel consumption is reduced by 35%, oil consumption by 50%. This increased fuel efficiency saves taxi drivers $500 per year, a 33% increase in income.


Envirofit currently has pilot projects in 3 historic/tourist cities: Vigan, Puerto Princesa, and Boracay. These projects aim to retrofit nearly 4000 vehicles. We are looking to replicate this project throughout the Philippines and to other countries.

Long-Term Impact

Our 3 pilot projects will ANNUALLY remove 127,000 automobile equivalents of pollution and infuse $1.1 million dollars into the local economy. We expect incidence of respiratory disease to decline with an improvement in the drivers’ quality of life.
