How to reduce your office carbon footprint: Easy strategies for an eco-friendly office

As the conversation around sustainability grows, reducing your office's carbon footprint has become important. For ESG managers and sustainability professionals, you need a well-rounded approach to think about both direct emissions—what's happening in your office—and the indirect emissions from your supply chain.

This blog explores practical strategies to help you reduce the carbon footprint of your office, from implementing energy-efficient solutions to encouraging sustainable employee behaviors.

How offices contribute to carbon emissions

The carbon footprint of an office is the total amount of greenhouse gases (GHGs) it emits — all the emissions that come from its day-to-day activities and upkeep. Businesses generate emissions directly through their operations and indirectly through their supply chains. These emissions can be categorized into three scopes, based on where they originate from.

Scope 1: Direct emissions

Scope 1 emissions are emissions which originate from sources directly owned or controlled by the company. This usually involves company-owned vehicles and on-site fuel combustion.

Scope 2: Indirect emissions from energy use

Offices use a lot of electricity for lighting, powering computers, air conditioning, and heating systems. According to the US Environmental Protection Agency (EPA), commercial buildings account for nearly 16% of all CO2 emissions in the country, largely due to electricity consumption.

Scope 2 emissions come from the consumption of purchased electricity, heating, or cooling, such as:

• Electricity for lighting
• Power for office equipment, like computers, printers, and servers
•  Electric or gas heating systems
• Cooling and air conditioning systems
• Power for elevators and escalators
• Electricity for office kitchens
• Hot water systems
• Ventilation systems
• Charging stations for electric vehicles

Scope 3: Indirect emissions from other sources

Scope 3 emissions account for 75% of the carbon footprints of most organizations. It covers indirect emissions that happen along a company's value chain, such as:

• Employee commuting
• Business travel
• The production of office supplies
• Outsourced services
• Waste disposal

So, employees driving to work, flying for business trips, or using public transportation all contribute to Scope 3 emissions.

Strategies to reduce office carbon emissions

Now that you know where emissions come from, let's explore some quick-win strategies to reduce the carbon footprint of your office.

1. Encourage remote or hybrid work models

Allow remote or hybrid work to limit the number of employees who commute to the office. A Work from Home (WFH) or hybrid setting can cut down on Scope 3 emissions from transportation. Plus, it can reduce the need for large, energy-hungry office spaces. In fact, WFH has lowered greenhouse gas emissions by 29.11% when compared with Work in Office.

2. Reduce energy usage in office buildings

Adjust the thermostat to a slightly higher temperature in the summer. This would reduce the need for air conditioning, leading to lower energy consumption and hence cutting down carbon emissions from power generation. Similarly, keep the thermostat lower in winter. This would reduce the energy needed for heating, which in turn lowers carbon emissions from power generation.

Consider installing energy-efficient HVAC systems to save energy and lower emissions, ensuring that filters are kept clean to prolong the product life and improve efficiency. Moreover, make it a policy that all office equipment is turned off when not in use as computers, printers and other devices drain energy when left on standby.

Retrofitting existing buildings also helps cut emissions. You can improve or add insulation, swap in energy-efficient windows, or install renewable energy systems. In fact, a report from C40 Cities shows that these upgrades could potentially slash carbon emissions by up to 50% by 2030.

For example, Adobe has redesigned its headquarters into an open-office layout called neighborhoods where it shuts down HVAC and lighting to neighborhoods unoccupied for over 15 minutes. Consequently, Adobe has achieved 65% lower energy consumption, making its workspace a sustainable office.

3. Minimize employee commutes

Promote alternative commuting options that can lead to fewer individual vehicle commutes and hence an eco-friendly office, such as:

• Carpooling
• Public transportation
• Cycling
• Walking
• Electric scooters
• Company shuttles

For example, Google has commuter shuttles in many of its campuses to decrease individual vehicle commuting. In fact, in 2023, its shuttle buses in the San Francisco Bay Area produced savings of about 14,900 tCO2e emissions. It is the equivalent of taking on average over 3,500 fuel-based cars off the road for a year.

4. Implement energy-efficient lighting and equipment

Switching to LED bulbs is a simple yet effective way to decrease energy use. These bulbs turn most of their energy into light instead of heat, unlike traditional incandescent bulbs, which waste a lot of energy as heat. Consequently, LED bulbs use much less power than regular lights.

Similarly, opt for Energy Star-rated office devices to ensure that your office equipment uses as little energy as possible. Thanks to advanced energy-efficient technology, these devices optimize energy consumption, reduce standby energy, and operate more efficiently than traditional lighting or equipment.

5. Adopt paperless solutions

Offices use large amounts of paper for printing documents, reports, and memos. In fact, the average office employee uses 10,000 sheets of paper a year. This excessive use leads to deforestation, energy consumption, and waste generation, impacting the environment and carbon footprint. So, opt for the following paperless solutions:

• Digital documents and files
• Cloud storage
• E-signatures
• Online collaboration tools
• Virtual meeting platforms
• Electronic invoicing and billing
• Digital note-taking apps
• Project management software
• Online forms and surveys

Sustainable office practices for long-term impact

Quick fixes to make a carbon neutral office are great first steps. But long-term sustainability requires more intentional practices.

1. Adopt a green procurement policy

To lower Scope 3 emissions, consider where your office supplies come from. Buy recycled or eco-friendly items, like notebooks and printer paper. Also, choose sustainable office furniture from local makers to lower carbon emissions from transportation. For example, Nestlé has a goal of cutting CO2 emissions by 50% by 2030. One way they aim to achieve this is through sourcing 50% of key ingredients through sustainable practices, such as regenerative agriculture.

Other steps you can take are to partner with sustainable suppliers to get biodegradable cleaning products or eco-friendly office supplies, like pens made from recycled materials. Moreover, assess the entire lifecycle of a product before buying it, from production and use to disposal, to choose the most sustainable option.

2. Waste reduction and recycling programs

Create recycling programs for paper, plastic, and electronics in the office to help employees recycle more. Cutting back on single-use plastics in the cafeteria or break rooms can also help. Plus, encourage the use of reusable cups, plates, and utensils in the office to reduce waste.

3. Water conservation in the workplace

Offices use a considerable amount of water, especially in kitchens and restrooms. To counter this, make sure there are low-flow fixtures installed in your office. Plus, promoting water-wise practices among employees can minimize water waste.

In addition, simple practices like fixing leaks promptly and encouraging employees to use only what they need can contribute to water savings.

Advantages of reducing the office carbon footprint

Some of the key benefits you can reap if you reduce the carbon footprint of your office are as follows:

• Lower energy consumption reduces utility bills and operational costs.
• Being environmentally conscious improves your image with customers and stakeholders.
• Lower energy consumption helps meet government regulations and avoid penalties.
• Employees are more motivated when they work for a company that cares about sustainability.
• Businesses focused on environmental, social, and governance (ESG) practices attract more investors interested in sustainable options.
•  Sustainable practices help companies adjust better to rising energy costs or problems in the supply chain.

How technology can help reduce your office carbon footprint

Technology offers powerful tools to help reduce the carbon footprint in offices. Here's how:

1. Smart thermostats and energy monitoring systems

Adjusting the heating and cooling systems based on real-time needs help optimize office energy use. You can set smart thermostats to lower the temperature when no one is in the office, so energy isn't wasted.

Energy monitoring systems help ESG teams see directly how much energy is being used. This makes it easier to find problems and take steps to save energy.

2. Leveraging video conferencing to cut business travel

Business travel, especially flights, contributes heavily to Scope 3 emissions. Encouraging virtual meetings over in-person trip scan lead to significant carbon savings. Using video calls for client meetings, team discussions, and interviews helps reduce the need to fly, which means a smaller carbon footprint.

Monitoring and reporting on office carbon footprint

Accurate ESG reporting is a must. To make meaningful progress, you must measure and track emissions regularly.

a.  Use technology to measure your office carbon footprint
