Manila Water reduced GHG emissions by 9,000 tons in 2021
Manila Water Company’s use of at least 13 million kilowatt-hours (kWh) of green energy in 2021 has reduced its greenhouse gas (GHG) emissions by over 9,000 tons.
According to Jocot de Dios, President and CEO of Manila Water, the utilization of 13.8 kWh of renewable energy enabled the water concessionaire to attain a decrease of 9,100 tons in its carbon emissions.
“This reduction is equivalent to about 45,000 mature trees capturing carbon dioxide per year. Each mature tree captures 20 kg of carbon dioxide every year,” said De Dios.
Manila Water’s cutback on GHG emissions came in the wake of initiatives aimed at reducing its impact on the environment, including the use of renewable energy (RE).
Solar panels have been installed in five of its treatment plants in and outside Metro Manila, registering a combined rate of about 300 kilowatts-peak (kWp) (usually on a sunny day in the afternoon).
Solar panels fitted at its sewage treatment plant in Magallanes have a rate of 105 kWp, while those at the FTI Septage Treatment Plant have a rate of 80 kWp. Over at the Delos Santos Pumping Station and the Laguna Water Booster 3 Facility, the solar panels mounted each has a rating of 32.7 kWp and 57 kWp, respectively. Those installed at the Clark Water Sewage Treatment Plan have a rating of 23 kWp.
In June 2021, Manila Water ventured into purchasing RE through a power purchase agreement, or the Green Energy Open Access, with a third party solar power plant. Manila Water and Cebu Water purchased 20% RE of its Open Access electricity requirements equivalent to 12.5 million kWh over a six-month period. In addition, the water concessionaire purchased third-party solar panels with a rating of 879 kWp for Thu Duc Water in Ho Chi Minh.
Apart from utilizing green energy, Manila Water commits to reducing and avoiding GHG emissions through energy efficiency, wastewater treatment expansion, watershed protection, and reforestation.
“Manila Water is set to develop its roadmap to Net Zero Target to align with the global warming limit of 1.5 degrees Celsius set in the Paris Agreement,” said De Dios.
The Philippines is party to the Paris Agreement, which entered into force in 2016, setting the global warming limit to 1.5 degrees Celsius compared to pre-industrial levels.
