Water
Volume of Water Used | Rain Harvesting (Water Reuse)
The Ateneo de Manila University's water consumption totaled 82,990 cubic meters for the period of June 2024 to August 2024. This figure depicts the inbound water supply, which includes both treated water and water supplied by the water utility company (Manila Water). The campus uses this water for a variety of purposes, including facility maintenance, academic building support, and daily student and staff requirements.
Volume of Water Used
Water consumption, in terms of volume of inbound water (treated/ extracted water) (in cubic meters) has dramatically varied over five years, with a record of 321,134 m³ in SY 2019-20, followed by a decline during the pandemic years of SY 2020-21 and SY 2021-22. With the post pandemic return to onsite operations soared at 304,738 m³ in SY 2022-23 and further climbing at 359,037 m³ in SY 2023-24, reflecting the post-pandemic return to full campus activity.

Rain Harvesting (m³)
Rainwater harvesting continues to be operational at the New Rizal Library and the Cervini Cafeteria. The collected rainwater is filtered and used to flush the toilets, further reducing the consumption of municipal water.
From June 2024 to September 2024, the University has harvested and re-used 1,542 m³ of rain water.

Energy
Total Energy Used | Total Energy from Renewables
For June 2024 to August 2024, the University's total energy consumption amounted to 13,348 gigajoules (GJ) (3,707,744 kWh) where 11,572 GJ (3,214,444 kWh) of it are sourced from low carbon sources.
Total energy used (GJ)
The University’s total energy use (in GJ and kWh) has varied widely across the five school years, with SY 2023-24 marking the highest energy consumption at 55,384 GJ (or 15,384,440 kWh). This also records a significant increase from SY 2022-23, which had 46,011 GJ (12,780,900 kWh).

Total Energy from Renewables (kWh)
As of August 2024 of this School Year (2024-25), the total energy from renewables used by the University is 3,214,444.09 kWh.
School Year 2023-24 shows a remarkable jump in renewable energy contribution at 645,840 kWh, which is higher than the previous year's renewable energy (569,804 kWh), demonstrating investment in renewable energy sources.
A noticeable leap took place between SY 2022-23 and SY 2023-24 with low-carbon energy usage increasing from 2,051 GJ to 2325.02 GJ, demonstrating the University’s shifting priorities towards decarbonizing its energy supply.

Food
During the 2023-2024 school year, the University generated 17.94 metric tons (17,937 kilograms) of food waste. This waste includes food scraps from the kitchen, trimmings, peelings, leftovers from the dining area, and used oil. Produced primarily through dining services and cafeterias, the University is actively addressing this issue by implementing waste reduction strategies, such as portion control and on-campus composting efforts. These initiatives aim to minimize the environmental impact of food waste while promoting sustainability and responsible consumption across the campus community.

Scope 1 & 2 for the Baseline Year | Baseline Year Began Recording Emissions GHG Standards
Ateneo de Manila University’s waste generation has exhibited a declining trend, from 261.12 metric tons (mt) in SY 2022-2023 to 259.12 mt in SY 2023-2024, with 28.98 mt recorded as of September 2024. Ateneo has also resumed its recycling efforts with 7.64 mt of wastes recycled so far in SY 2024-2025, following 11.01 mt recycled in SY 2023-2024 after a hiatus in SY 2022-2023. As of September 2024, Ateneo sent 21.34 mt to the landfill, down from 248.11 mt in SY 2023-2024 and 261.12 mt in SY 2022-2023.

Scope 1 Emissions
- SY 2022-23: Scope 1 emissions were recorded at 63.41* tCO2e (tons of CO2 equivalent), indicating a relatively low level of direct emissions, likely from fuel use in campus vehicles or on-site energy production.
- SY 2023-24: Scope 1 missions increased, doubling to 138.21 tCO2e. This suggests increased direct energy usage, from a return to the post pandemic full campus operations.
Note: SY 2022-23 data adjusted due to additional data from University-issued vehicles (updated on 20250314)

Scope 2 Emissions
- SY 2022-23: Scope 2 emissions were monitored at 6,420.79* tCO2e, evidencing a significant carbon footprint from electricity consumption.
- SY 2023-24: Scope 2 data shows an increase to 10,221.22 tCO2e indicating higher electricity use, resulting from upgraded physical facilities and campus activity.
Note: SY 2022-23 data adjusted due to new emission factor provided by the Department of Energy (DOE 2019-21 NGEF). Updated on 20250314

Sustainable Practices
Bicycles on Campus | EJeep: Passenger Volume | Pedestrians | Vehicles | School Buses | Electric Vehicles
Ateneo de Manila University promotes sustainable and environmentally friendly commuting to address campus vehicular transportation hazards. These practices include constructing seamless paved roads for walking, cycling routes, and carpooling through the electric jeepney. Additionally, the University provides a tricycle station for commuters in an effort to reduce carbon emissions and manage on-campus traffic. It is also a way for the University to socialize a campus-wide sustainability culture.
