Sustainability Report 2024
Governance Camberwell Grammar School (CGS) is a progressive K–12 independent all-boys school located in Melbourne, Australia. The School Council sets the strategic direction, while the Principal and Leadership Team oversee its implementation. In 2024, total enrolments reached 1,373 students. In 2020, the Council elevated sustainability from a series of initiatives to a core pillar of the Strategic Plan, building on five years of dedicated environmental efforts. By the end of 2021, the School further reinforced its commitment by setting an ambitious target to achieve Net Zero emissions by 2030. This commitment catalysed a collaborative effort across Leadership, Facilities and Operations, staff, students, and parents to embed sustainability throughout the school. This collective action evolved into the CGS Sustainability Program Implementation Model, structured around three key spheres: Strategy, Facilities & Operations, and On-the-Ground initiatives. By aligning these areas, CGS ensures a cohesive, whole-school approach in which all stakeholders contribute to the development, execution, and longevity of impactful environmental actions. This framework empowers the Camberwell Grammar community not only to reduce its environmental footprint but also to cultivate a lasting culture of sustainability - fostering environmental responsibility among students, their families, and the broader school community.

Sustainability Report 2024
Message from the Principal Having this year commenced in the role of Principal, I am proud to present Camberwell Grammar School’s 2024 Sustainability Annual Report. Reflecting on the significant progress we achieved last year, I feel privileged to lead a community driven by ambitious, valuesbased goals under the ‘Secure and Sustainable Operations’ pillar of our Strategic Plan. This report celebrates our achievements while identifying areas for continued growth as we navigate an increasingly challenging climate landscape.
Ben Jeacocke
The urgency of our mission to have sustainability at the forefront of our daily operations and our plans for the future has never been more apparent. With global CO2 levels exceeding 426 ppm, recordbreaking temperatures, widespread biodiversity loss and severe storms becoming more frequent, we recognise our responsibility to reduce our environmental footprint while empowering the next generation of global citizens. In 2024, this commitment translated into tangible action and measurable progress. I am pleased to report the School’s greenhouse gas emissions have reduced by 64% since baseline year, 2017, due to switching to 100% renewable energy. In 2024 the School emitted 1014 tCO2e, just over 5% off the annual ambitious target of 952.5 tCO2e. Camberwell Grammar School will continue to strive for emissions reduction with dedication, innovation, and collaboration of our students, staff and families.
Principal, Camberwell Grammar School Gas consumption and Biodiversity performed better than the annual target with notable near target performance for Transport (Road) and Materials Recycled. This progression reflects a cultural shift towards sustainability that we have diligently fostered over recent years. Challenges around electricity consumption, water usage, and landfill reduction remain priorities. To address these areas, we continue to integrate sustainability principles into our curriculum and co-curricular programs, nurturing a culture of environmental stewardship that encourages students to think critically and act responsibly. Continued progress will require ongoing focus, continued education, and a collaborative, whole-school approach. Our Sustainability Program Implementation model, which outlines a holistic approach encompassing leadership, facilities and operations, and engagement with staff and students, is now being shared more broadly across the education sector. This model has positioned us as a leader in sustainable school practice. Recognition as one of Victoria’s Top 20 Sustainability Schools and official certification from Sustainability Victoria further affirm our impact and influence in the broader educational community. Our commitment to strengthening leadership in sustainability reporting and innovative practices remains steadfast. Ongoing partnerships with organisations including the Interschool Sustainability Partnership (ISP), Eastern Alliance for Sustainable Learning (EASL), Boroondara Council, Katalyst, the Global Alliance of Leading Edge Schools for Sustainability (GALESS), and Electrify Boroondara, provide valuable insights, resources, and collaborative opportunities that continue to enhance our sustainability efforts. Looking ahead, Camberwell Grammar School remains focused on improving performance in key areas through strategic planning, transparent reporting, and collaboration across all levels of our community. Empowering students and staff to take ownership of initiatives in sustainability, fosters creativity, resilience, and a shared sense of responsibility. These are qualities which are essential for overcoming the complex environmental challenges that lie ahead. As Camberwell Grammar School begins a new chapter in its history, as Principal, I am excited to build upon the strong foundations already in place. Achieving long-term sustainability requires unwavering commitment from us all, and I have no doubt that, together, we will continue to lead with innovation, care, and a global perspective for a more resilient and responsible future.

SUSTAINABILITY AT THE SCHOOL STUDENT LEADERSHIP Tony Zhang - 2024 Sustainability Prefect 2024 was another outstanding year for sustainability at Camberwell Grammar, filled with impactful initiatives, strong community engagement and exciting progress towards our environmental goals. Green Week kicked off the year with a focus on Recycling, featuring a waste quiz, a breakfast for those who walked or rode to school, and a warm pumpkin soup day. The Prefect Rubbish Race, a new highlight at the Senior School House Athletics, saw Bridgland take the win in a thrilling 4x100m relay sorting waste. Students and staff embraced sustainability by wearing green, enjoying a lunchtime concert, and supporting Zoos Victoria’s Fighting Extinction Campaign. A school-wide vote determined that $5,085.20 would go towards saving the Orange Bellied Parrot. FOGO recycling and a new Victorian Container waste stream were significant areas of focus in 2024. Collaborations with Chartwells, our canteen contractors, also led to increased biodegradable packaging, a key step towards our 2030 waste targets. In Term 3, 135 students and staff planted 150 native plants for School Tree Day, strengthening links with our local ecosystem. Meanwhile, the Interschool Sustainability Partnership continued to foster collaboration between schools, highlighting the shared experience of young people growing into a changing world. Best wishes to Ivan Zhang as he leads sustainability efforts in 2025!
Student Sustainability Engagement Reflecting on their 2024 sustainability initiatives, Camberwell Grammar student groups Towards 2050, the Garden Group, Green Ninjas and the Beekeepers explore how engaging in activities empowered them to drive positive change and take agency in building a sustainable world. School’s Tree Competition
Interschool Sustainability Partnership (ISP)
I thought it would be fun to compete in the competition — I can’t believe I won! Taking my camera outdoors helps me notice things I might otherwise overlook. Photos remind us to protect the environment and take action for sustainability. (Ryan Ellis, Year 8)
ISP meetings let us collaborate with nearby schools, share ideas and discuss sustainability projects. It’s a great way to learn, connect, and enjoy some good food. (Perry Millard, Year 8).
Climate Change Education Forum Attending the Climate Change Education Forum allowed us to connect with like-minded students and discuss ways to reduce environmental impact. We designed sustainability solutions alongside professionals, gaining insight into real-world challenges while having fun. (Thomas Klebanowski, Year 10) Open Day I enjoyed running the stall, sharing the benefits of growing tomatoes and strawberries. Talking to parents and peers about sustainability was great. My family still grows the plants we bought and can’t wait to enjoy their produce! (Christopher Chinowutthichai, Year 8) Greenfleet Offset Planting I enjoyed participating in the Greenfleet planting at Mt Emily, Gippsland. The school uses Greenfleet to offset air transport emissions. We planted native trees and learned about the impact of climate change and deforestation. (Peter Shihata, Year 9) Hand Dryer Project Replacing paper towels with hand dryers reduces landfill waste. I loved that my ideas were valued and helped shape the final decision. (Ishaan Ghosh, Year 8) 6
Hearing about other schools’ initiatives and exchanging ideas helped us improve our projects. (Oscar Wallis, Year 9) Garden Club The Garden Club taught me how to care for plants. Seeing our work result in produce for events like pumpkin soup day was rewarding. (Oshan Tennakoon, Year 9) Schools for Wildlife Planting was a great way to help the planet. We used tools to help the plants grow strong. Every day I pass by and think, “I planted that!” (Oliver Chong and Zahary Lu, Year 4B) Green Ninjas ‘It’s wriggling!’ ‘Can I water the plants?’ ‘Can I collect food scraps?’ Green Ninja students love hands-on gardening. Every Wednesday, Mr Haines teaches composting, planting, and insect exploration. Students enjoy digging, harvesting, and using butterfly nets and magnifiers to observe nature. (Green Ninja student comments, Prep to Year 1). Beekeeping I love bees and honey! Suiting up in a beekeeping suit and packing down the hive was a great learning experience. Bees are vital for pollination. Making bee hotels and seed bombs was fun too! (Aryan Ananthapavan, Coby Scheer & Mark Wu, Year 10) Sustainability Report 2024

Staff Engagement Cultural shifts and sustainable behaviours were evident at CGS, with staff initiating innovative and creative approaches to embed sustainability into their practices. These efforts align with the school’s commitment to achieving Net Zero, fostering a sustainable responsible community. Year 7 Programming - Embedding Sustainability into Curriculum
Business and Operations Managers - Journey to Net Zero Event
Ciara Chaomhanach, Deputy Head of Middle School, partnered with the Sustainability Team to launch the inaugural Year 7 Sustainability Program, immersing students in hands-on Net Zero learning with community partners. Activities included visits to a recycling facility, the Boroondara Council Garden and the Common Ground Farm. The students also tried their hand at bike maintenance, beekeeping and active transport during the week before showcasing their learning through insightful presentations.
Chris Lloyd, Business Manager, and Jessica Stryker, Head of Facilities & Operations alongside the Sustainability Team, hosted the ‘Journey to Net Zero’ event for school Business and Operations Managers. Over 50 schools attended to explore CGS’s Net Zero commitment, sharing insights, successes and challenges in sustainability from a strategic perspective.
Music Production – Circular Economy Focus Alex St Vincent Welch’s Junior School Treasure Island production brought Camberwell Grammar’s sustainability vision to life, using repurposed materials for sets, props, and costumes. Donated sheets became sails, recycled timber built the set, and upcycled costumes played a starring role. Camberwell Girls Grammar supplied recycled cloth makeup wipes, and ticket sales supported the Dolphin Research Institute in Hastings. Languages - Landfill Waste Free Event Jessica Cormick, Indonesian teacher, applied Circular Economy principles to redesign the Year 7 Indonesian Lunch, transforming it from a high-waste event into a model of sustainable practice. She introduced reusable plates, cups and cutlery, a FOGO waste stream, locally sourced low-footprint food and digital resources. Her efforts have since inspired a similar shift in the Chinese department.

Operations and Facilities - Resource Reduction Focus Liz Sayers, Functions & Facilities Coordinator, minimises resource use through efficient HVAC management and sustainable event practices. Jessica Stryker, Head of Facilities & Operations, led efforts to divert waste during the annual cleanup, repurposing, donating, or auctioning large items, such as old classroom furniture to reduce landfill and emissions. Development & Marketing - Engaging Community Karley Knight, Parents & Friends Coordinator, worked with the Friends of Groups (FOG) and the Sustainability Team to align Open Day stalls and events with Net Zero goals. The FOG information booklet went digital with a Sustainability Support section, and FOG events are now zero-landfill, using only compostable or reusable materials. Grounds & Maintenance - Sustainability Innovation Liam Randall, from the Grounds Team, integrates sustainability into daily grounds and oval maintenance. His initiatives include selecting drought-resistant turf, auditing fuel-powered equipment for future electrification, and contributing to the upgrade of the water tank irrigation system. His efforts play a vital role in enhancing sustainable water and resource management. Sustainability Report 2024

Electricity Electricity Spotlight In 2024, electricity consumption remained a key focus for Camberwell Grammar School’s sustainability efforts, totalling 2,140.92 MWh. While the school sources all electricity from renewable sources, we are committed to reducing consumption. However, our total consumption in 2024 exceeded the annual 1,513.42 MWh target due to seasonal heating and cooling demands. Seasonal demands during Q1 and Q2-3 for air conditioning and heating, respectively, drove up consumption. Although Q4 saw a steady reduction in grid electricity usage, reliance on Large-scale Generation Certificates (LGCs) continued to contribute to overall emissions. The school is actively exploring electrification projects to improve energy efficiency.

Recycling outperformed the 2024 target of 141.3 tonnes, reaching 166 tonnes and comprising 73.5% of total waste. Strong community engagement and education campaigns improved FOGO, co-mingled, green, and paper/cardboard recycling. Green waste recycling remained high in Q1 and Q3 due to holiday gardening and made up 57% of all recycling. The container deposit scheme reduced co-mingled waste in Q4. Landfill waste totalled 60 tonnes, surpassing the 42.5-tonne target, primarily due to Q2 and Q3 renovation projects and issues surrounding contamination. The school continues to work on contamination through education campaigns and long term sustainability education. In doing so, we aim to achieve lasting landfill reduction while promoting and strengthening sustainability education to support long-term waste reduction.

RESOURCE USE IN OPERATIONS
Biodiversity Biodiversity Spotlight The school continues to enhance biodiversity through habitat restoration and native plant landscaping. In Term 3, a Biodiversity Audit recorded a Habitat Quality Assessment Score (HQAS) of 76, meeting the 2024 Target. The audit highlighted the need to increase mulching and habitat creation for native species. Key green space projects included participation in the City of Boroondara - funded CERES Schools for Wildlife Program, Indigenous tree planting at Gate 6, and Senior School Green Development. The Gardening Group and Beekeepers Program remained highly engaging for students, fostering environmental stewardship. Future biodiversity plans focus on expanding native planting, improving mulching and weed control, and increasing community engagement in conservation projects and biodiversity events. By strengthening these initiatives, the school aims to enhance habitat quality.

Landfill & recycling - baseline year altered to 2022 due to incomplete data from 2017/18. Paper - baseline year altered to 2022 due to incomplete data in 2017. Air travel - 2018-19 data was initially used for the baseline year. This baseline year has now been changed to 2023 for a more representative data set. Biodiversity - used 2022 HQAS (Habitat Quality Assessment Score) score as 2019 score of 84 reflects a different audit template affecting HQAS calculations. Gas - 2017 baseline data missing Wheelton Bld metre data and 6 months of data for Kingussie Flat. 2018 Sport Centre gas usage used as the baseline to account for missing data and separate the pool gas usage. Pool water usage estimated based on average daily usage of 8kL, calculated from the 12 months of data provided from 2021/2022. Student road transport baseline year is 2022 due to incomplete data in 2017.

2030 targets based on student numbers use 1354 (2022 student numbers). Emissions target for 2030 is based on the most recent emissions factors when Baseline Report was released (2022). Gas targets were updated in 2023 after the Sustainability Plan and Baseline Report due to a change in methodology for separating and estimating pool gas use, i.e. moving from a pool usage estimate to accounting for actual Sports Centre total gas use. Total waste targets updated in 2023 after the Sustainability Plan and Baseline Report was published due to improved methodology for weight calculation, i.e. using weighted average of waste densities between landfill & recycling mix. Emissions targets for 2024 and beyond assume all air travel emissions are 100% offset. Total electricity use targets for 2022 to 2030 are based on 2021 actual solar generation recorded on ResourceSmart Schools (RSS), yearly panel degradation of 0.523%, and 2022/2023 actual solar split for 2022/2023-2030 targets.
•
•
From July/August 2023, the weight of landfill and recycled materials was obtained from the waste contractor, with the exception of organics for the following periods: July September, December; as well as green waste in Q4. Before that, weights were calculated from the waste volumes on RSS and the following density factors. When weight was unavailable, this original methodology used industry waste density factors.
Diesel assumed to be used in third-party hire vehicles (buses etc.)
