Our progress towards net zero carbon emissions

At the University of Essex, sustainability is a shared commitment. We want to reach net zero carbon emissions by 2035 and we're making real strides towards that goal through impactful projects across our campuses. Here's a look at some recent achievements, and we see what's on the horizon.

Decarbonising Essex Business School

The removal of gas heating at Essex Business School has been an important step. This change alone has reduced our carbon footprint by 11 tonnes of CO₂e annually, underscoring our commitment to reduce reliance on fossil fuels.

Harnessing solar power in South Courts

Our latest solar panel project at South Courts is underway, with over 1,500 solar panels being installed. This array will save 101 tonnes of CO₂e each year, providing a renewable energy source that helps to power our campus sustainably.

LED lighting upgrades

Energy-efficient LED lighting has been another key part of our carbon reduction strategy:

• Colchester Campus: The Psychology Building, Day Nursery, and Canteen have been upgraded to LED lighting, saving 19 tonnes of CO₂e per year.
• Southend Campus: University Square accommodation has had lighting replaced that will reduce emissions by 41 tonnes of CO₂e annually, with planned upgrades at the Gateway Building and Clifftown Theatre promising to save an additional 63 tonnes of CO₂e each year.

Improved energy efficiency with windows upgrades

Enhanced thermal efficiency is now a feature at the Constable and John Tabor buildings thanks to new energy-efficient windows. This improvement reduces gas use and cuts energy consumption by 20%, making these buildings more sustainable and comfortable for users.

Better roof insulation

Roof insulation projects in the older 1960s estate, including RAB Butler, Square 5, and Maths Link will reduce heat loss by 30%. This improvement not only lowers our carbon emissions but also enhances comfort and reduces energy bills.

Reducing water and gas consumption

Eco-friendly taps and flow restrictors are being installed across academic and residential buildings, leading to an estimated 56-tonne reduction in CO₂e by saving on water usage and water heating requirements.

Efficient heating and cooling in the Gateway Building

Heating and cooling in the Gateway Building at our Southend Campus have been optimised according to occupancy patterns, further supported by minor upgrades to the Building Management System for enhanced control and energy savings. Additionally, PIR (passive infrared sensor) occupancy sensors in 10 offices are showing a 30% energy savings, showcasing how small changes can lead to significant impact.
