Electric Jeepneys Offer Cleaner, Sustainable Alternative to Diesel Vehicles
ADB should replicate ‘climate friendly cities’ initiative
By Athena Ronquillo-Ballesteros, Greenpeace
Vehicle emissions are a major contributor to worsening air pollution levels in Asia. At the same time, the transport sector is the fastest growing contributor to increased global GHG emissions. The Asian Development Bank is presented with a major opportunity to help drive Asian cities to choosing cleaner forms of public transportation relying purely on renewable energy. The pilot fleet of six electric jeepneys launched recently in the cities of Makati and Bacolod forms part of a larger multi-pronged integrated sustainable transport and waste management project: the climate friendly cities project (CFC).
The climate friendly cities (CFC) project seeks to provide clean energy solutions to address a range of urban environmental problems common in most Asian cities while creating innovative solutions for mitigating climate change through a commercially-viable and income-generating business model. Developed by various partner organizations led by the Green Renewable Independent Power Producer Project, Inc. (GRIPP), Greenpeace and Solar Electric Co, the idea is to revolutionize some of the most iconic public transportation vehicles in the mega cities of Asia by powering them with electricity from biogas, a renewable energy source. The bio-power plant will utilize the city’s food waste as feedstock to produce gas that will, in turn, be used to generate electricity to power the fleet of electric jeepneys.
The original Philippine jeepney is a cultural icon, first manufactured by World War II mechanics from leftover vehicles of American troops. The jeepney’s flamboyant design is instantly recognizable and synonymous for us here in the Philippines. The jeeps were then refurbished to accommodate several passengers, added metal roof for shade and decorated with vibrant colors and bright ornaments making them a popular and creative public transportation vehicles. But while it provides one of the cheapest means of commuting, the diesel-based jeeps are major source of air pollutants, posing a health risk for drivers and commuters. They are also highly inefficient and exact a heavy toll on drivers’ pockets with high fuel and maintenance costs. The fuel use for example of a 16-passenger jeepney is almost equal to a 54-passenger air-conditioned bus. With major roads clogged by empty jeepneys cruising for fares, there is a threat to sideline the jeeps from the streets of Metro Manila and other cities.
For the pilot cities Makati and Bacolod, the potential environmental, economic, health and social benefits of the project are obvious: reduction of greenhouse gas emissions such as CO2 and methane; reduction of air pollutants; containment of leachate that contaminate ground water aquifers and waterways; treatment of organic waste of its pathogenic and toxic materials; and improved local air, health and safety.
More importantly the electric jeepneys will provide two to three times more income to the vehicles’ drivers. The gross amount of fares that a driver collects in a day is roughly 1800-2000 pesos. From that, he spends at least 800 pesos to purchase diesel and an average of 400-500 as hire payments to the jeepney owner/operator (locally known as ‘boundary’). On a good day, he returns home with 240 pesos. On a bad day, he may end up owing. The electric jeepneys will significantly increase by two to three times more the net take home pay of the drivers by reducing their expenses on fuel. It also intends to demonstrate to operators that electric jeepneys are a viable investment because reduced maintenance costs will increase financial returns.
While the electric jeepney fleet is a first in Southeast Asia, each of the CFC project components already exist and implemented in various countries. There is the successful case of the electric SAFA Tempos (mini-buses) in Nepal; there are biogas digesters in many parts of Asia, then there are community charging stations for solar systems in several communities in the region. The transport and waste management service aspects have been tested reliably in the past and are therefore market ready. The only real innovation introduced by the Project is the ‘manner in which the technologies are made to work together’ and this requires careful planning. The integration of the sustainable transport, waste management and recharging components into one cohesive package of cleaner, safer, renewable energy options is indeed an embodiment of our vision – the energy revolution.
This is where the ADB’s role becomes critical. If we are serious about averting dangerous climate change, we need a fundamental shift in the way we produce and consume energy.
The climate friendly cities project is only a small step towards this vision.

COPD - chronic obstructive pulmonary diseases
PTB - pulmonary tuberculosis
Doctors say that COPD, such as emphysema and chronic bronchitis, can be aggravated by air pollution. Those with COPD are also more susceptible to PTB, which is caused by an airborne bacteria. Victims of COPD suffer from chronic cough with phlegm, wheezing, and shortness of breath. They also sustain irreversible damage to the lungs. PTB sufferers’ lungs also develop permanent scars. At least 22 million Filipinos are suffering or exposed to various stages of TB. This means that one out of four Filipinos are exposed to the disease.

CLIMATE FRIENDLY CITIES PROJECT
Environmental Benefits
The project will significantly reduce pollution in Bacolod City, which is caused by mass transport and solid waste. By converting organic waste from the city’s wet markets and commercial food establishments into biogas to generate electricity for transport, the following environmental benefits are achieved:
- Reduction of greenhouse gas emissions produced by the release of methane gas from open dumpsites;
- Reduction of air pollutants such as carbon dioxide and nitrous oxide produced by the operation of diesel-engine jeepneys;
- Containment of leachate that contaminate ground water aquifers and waterways;
- Displacement of fossil fuel with the use of methane collected for electricity production;
- Treatment of organic waste of its pathogenic and toxic materials; and
- Improved local air, health and safety;
Moreover, the project propagates a better system for waste management. This provides the following ancillary benefits:
- An environmentally sound alternative to the open dump site;
- Reduction in waste management burden on the LGU; and
- Reduced residual volume of land-filled solid waste by up to 85%.
On the other hand, the HSAD Biogas Facility provides additional benefits from its process of treating organic waste and converting it into biogas, namely:
- Containment of 100% of emissions of Volatile Organic Compounds;
- No hazardous by-products;
- An entirely closed system that converts up to 95% of available carbon to biogas; and
- Contribution to improving local soil conditions.
Furthermore, the switching of fuel from diesel, which is used by almost all jeepneys and by most electric power plants found in the island grids, to electricity adds the following benefits:
- Reduction of CO2 and NOx by 3140 gram and 16 grams respectively per liter of avoided diesel;
- Lesser cases of pulmonary disease caused by air pollution; and
- Significant decrease in the Peso 21 billion of yearly economic losses of urban centers caused by health related problems due to air pollution.
Environmental benefits in terms of Greenhouse Gas reductions may be measured using baseline methodologies approved by the UNFCCC. Applicable measurements may be found in calculations used in the following approved methodologies:
- AMS III.D – “Methane Recovery”,
- AMS I.D – “Renewable Energy Generation, and
1996 IPCC – “Guidelines for National Greenhouse Gas Inventories”.
Based on an installed capacity of 75 kW and a plant operating efficiency of 45% on a 24-hour per day schedule, the project has an annual electricity generation of 405 MWh.
1) Emission reductions of the electricity generation component of the project using an emission coefficient of 0.80 (tonnes CO2e /MWh) are:
0.80 tons CO2/MWh x 405 MWh/year = 324 tonnes CO2e/year
2) Emission reductions of the methane capture component of the project was calculated using a 15% Degradable Organic Content (DOC) of waste with 0.77 factor for dissimilation and 0.2 factor for decay. Other factors used were Methane fraction in landfill gas (50%), Oxidation (10%) and Methane Correction (0.8). This resulted in a ratio: every ton of organic waste collected/year will be equivalent to 0.9634 CO2e reduced in a year.
Therefore, if the project collects 20% of waste generated or 120 tons of organic waste per day, the emission reductions are:
120 MT x 365 days x 0.9634 CO2e/year = 42,190 MT CO2e/year.
3) And the displacement of diesel fuel to operate a fleet of 35 jeepneys, reduces emissions as shown below:
35 jeepneys x 30 liters/day x 353 days/year = 370,650 liters x 0.00088 (specific gravity of diesel or t/li) x 3.20236 (European CO2e emission factor for diesel fuel) = 1,044.81 MT CO2e/year.
Therefore, the project annual Emission reductions for the three project components (waste conversion, electricity production and fuel switching for transport) total 43,450 MT CO2e.
