Reducing your business’s carbon footprint is no longer a nice-to-have. Customers, employees, investors, and regulators increasingly expect organizations to understand—and actively reduce—their environmental impact.
Every organization has opportunities to make meaningful changes, whether it operates a single office, manages a fleet, manufactures products, or sends employees around the world. The most effective approach is not a one-off sustainability initiative; it is a practical, company-wide program that measures emissions, prioritizes the biggest sources, reduces them at the source, and addresses unavoidable residual emissions responsibly.
This guide explains how to reduce your company’s carbon footprint across operations, offices, employee commutes, and business travel—including how to create a sustainable travel policy and assess carbon offset programs.
What does a business carbon footprint mean?
A carbon footprint is the total amount of greenhouse gases generated by an activity, organization, product, or service. It is often expressed as carbon dioxide equivalent (CO2e), which accounts for carbon dioxide and other greenhouse gases, such as methane, in a common unit.
For a business, the footprint is much broader than the energy used in an office. Consider a bottle of water consumed at work: its footprint can include sourcing the water, manufacturing the bottle, packaging, transportation, and the energy used across the supplier’s operations.
Business emissions are commonly grouped into three categories:
Scope 1 emissions: Direct emissions from sources a company owns or controls, such as company vehicles or on-site fuel use.
Scope 2 emissions: Indirect emissions from purchased electricity, heating, cooling, or steam.
Scope 3 emissions: Other indirect emissions across the value chain, including business travel, employee commuting, purchased goods and services, waste, and transportation.
For many companies, Scope 3 emissions represent a substantial share of their total footprint. Business travel, procurement, commuting, and suppliers should therefore be part of any credible emissions-reduction strategy.
Why reducing your carbon footprint matters
Reducing emissions helps limit the environmental impact of business activity, preserve resources, and support efforts to slow climate change. It can also create practical business benefits, including:
Lower energy, fuel, waste, and materials costs
Greater resilience to changing regulations and reporting requirements
Stronger employer branding and employee engagement
Improved customer and investor confidence
More efficient processes and purchasing decisions
Clearer progress toward ESG and net-zero goals
Sustainability is also increasingly connected to reputation. Organizations that make measurable, transparent progress can demonstrate responsible leadership, while unsupported environmental claims can create greenwashing risks.
The role of sustainability managers
A sustainability manager helps turn environmental commitments into measurable action. Their responsibilities may include:
Measuring the organization’s environmental impact
Setting emissions-reduction targets
Identifying high-impact operational changes
Developing policies for energy, travel, procurement, waste, and suppliers
Supporting environmental compliance and reporting
Training employees and encouraging participation
Monitoring progress and improving programs over time
Even without a dedicated sustainability manager, companies can assign clear ownership to a cross-functional group that includes facilities, finance, procurement, HR, travel, and leadership teams.
Start with a carbon-reduction strategy
The most effective carbon-reduction plans follow a simple hierarchy:
Measure emissions to understand the baseline.
Avoid unnecessary emissions by changing processes and behaviours.
Reduce remaining emissions through efficiency, lower-carbon alternatives, and better purchasing decisions.
Address unavoidable residual emissions with carefully selected, verified carbon credits where appropriate.
Report progress transparently and review the strategy regularly.
Carbon offsetting can play a role, but it should complement—not replace—direct emissions reductions.
10 company-wide ways to reduce your carbon footprint
1. Measure your carbon footprint
You cannot manage what you do not measure. Start by assessing the emissions associated with your operations, including energy use, office supplies, waste, business travel, employee commuting, fleet activity, and major suppliers.
Businesses can use carbon-accounting tools, emissions calculators, travel data, utility bills, procurement records, or specialist sustainability consultants. A consultancy can help measure emissions, develop a reduction plan, support implementation, provide employee training, and assist with relevant certifications.
For business travel, a centralized booking platform can make it easier to track emissions by route, traveller, supplier, or department. Perk’s Green Trip carbon-offsetting solution helps companies calculate and report on travel-related emissions while supporting certified environmental projects.
2. Set practical targets and assign accountability
Once you know your baseline, set reduction targets that are specific, measurable, and relevant to the areas where your company has the greatest impact.
For example, a company may target:
Lower electricity consumption per square foot
Reduced emissions per employee or per kilometre travelled
A higher percentage of renewable electricity
Fewer short-haul flights where rail is practical
Reduced waste sent to landfill
Lower emissions from fleet operations
Assign owners for each initiative, set deadlines, and review performance regularly. For growing businesses, intensity targets—such as emissions per employee, trip, kilometre, or unit of revenue—can provide a useful starting point.
3. Apply the three Rs: reduce, reuse, recycle
The principles of reduce, reuse, and recycle can be applied across operations, packaging, office supplies, food, technology, and facilities.
Start by asking:
What purchases can be eliminated or reduced?
What can be repaired, reused, or shared rather than replaced?
Which materials can be recycled or composted?
Can packaging be reduced or switched to lower-impact alternatives?
Can suppliers provide reusable, refillable, or recycled-content products?
Reducing consumption is often the highest-impact and lowest-cost action. It can also reduce procurement, storage, and disposal expenses.
4. Choose renewable electricity and improve energy efficiency
Switching to renewable electricity can reduce the emissions associated with purchased energy. Ask your existing supplier whether it offers a renewable-energy tariff or contract, and consider alternatives if it does not.
Renewable energy works best alongside energy-efficiency improvements. Before adding new equipment or changing suppliers, identify where energy is being wasted through inefficient lighting, heating, cooling, appliances, or equipment left running unnecessarily.
5. Use sustainable web hosting and digital infrastructure
Digital services have an environmental impact. Websites, cloud storage, data processing, video streaming, and external servers all require electricity.
When selecting web hosting or cloud providers, look for companies that demonstrate:
Energy-efficient infrastructure
Renewable-energy procurement
Transparent emissions reporting
Efficient cooling and data-centre operations
Credible environmental commitments and, where appropriate, verified carbon-reduction programs
Companies can also reduce digital waste by deleting unused data, optimizing websites and media files, limiting unnecessary file duplication, and extending the lifespan of IT equipment.
6. Improve purchasing and supplier decisions
A company’s supply chain can be a major source of Scope 3 emissions. Consider environmental performance alongside cost, quality, and service when selecting suppliers.
Questions to ask suppliers include:
Do they measure and report their emissions?
Do they use renewable energy or energy-efficiency measures?
What packaging and transport practices do they use?
Can they provide recycled, reusable, or lower-carbon materials?
Do they have environmental certifications or credible sustainability targets?
Supplier engagement is especially important for organizations that purchase large volumes of products, materials, catering, packaging, or transportation services.
7. Reduce fleet and road-travel emissions
Road travel may be essential in some sectors, but companies can still reduce associated emissions by improving fleet efficiency.
Useful measures include:
Replacing older vehicles with electric, hybrid, or fuel-efficient models
Choosing vehicles with smaller engines where appropriate
Optimizing routes and consolidating deliveries
Reducing idling and unnecessary journeys
Maintaining tyres, engines, and vehicles regularly
Providing fuel-efficient driving training
Encouraging carpooling for work-related travel
Where electric vehicles are not yet practical, fuel-efficient vehicles and better route planning can still reduce fuel use and operating costs.
8. Promote greener employee commutes
Employee commuting can make up a meaningful share of a company’s indirect emissions. Employers can help by making lower-carbon commuting more accessible and attractive.
Options include:
Offering public-transit subsidies or discounted passes
Providing secure bicycle parking, showers, or bike-sharing programs
Supporting carpooling
Offering incentives for electric vehicles
Introducing flexible start times to reduce congestion
Allowing hybrid or remote work where operationally possible
A hybrid work model can reduce commuting emissions while also lowering office energy and space requirements. Tax incentives may be available for some green-commute benefits, depending on the country and program.
9. Support credible environmental and community projects
Businesses can extend their impact beyond their own operations by supporting environmental initiatives in their communities. This may include tree planting, habitat restoration, local clean-ups, food-rescue programs, environmental education, or conservation projects.
Participation can take the form of financial contributions, employee volunteering, matched donations, or company-wide initiatives. The strongest programs connect to a company’s actual footprint and community rather than serving as a substitute for internal emissions reductions.
10. Educate and involve employees
Employees make many of the decisions that affect a company’s footprint: how they travel, use energy, purchase supplies, manage waste, and select vendors.
Education should be ongoing, practical, and relevant to employees’ roles. Share clear guidance, explain why actions matter, and make sustainable choices easy to follow. Regular updates on progress can help employees see the results of their efforts and maintain momentum.
14 ways to reduce your office carbon footprint
Workplace emissions often come from electricity, heating, cooling, equipment, food, waste, and commuting. The following actions can make offices more efficient without compromising employee comfort or productivity.
1. Choose energy-efficient appliances
When purchasing or replacing office equipment, choose energy-efficient models. Look for relevant efficiency ratings, such as ENERGY STAR certification where applicable, and consider the total energy use of printers, monitors, kitchen appliances, servers, and other frequently used equipment.
Efficient equipment can lower both emissions and utility costs over its lifetime.
2. Upgrade office lighting
LED lighting generally uses less energy and lasts longer than older lighting options. Maximize natural daylight where possible, use adjustable blinds or shades, and install motion sensors in low-traffic areas such as meeting rooms, bathrooms, storage spaces, and corridors.
Dimmable lights and occupancy sensors can further reduce unnecessary electricity use.
3. Optimize heating and air conditioning
Heating and cooling can account for a major share of office energy consumption. Review thermostat settings, maintenance schedules, insulation, window coverings, and airflow to identify waste.
Avoid overheating or overcooling workspaces. Efficient temperature management can improve employee comfort while lowering energy use and costs.
4. Reduce food waste
Food waste carries the environmental cost of growing, processing, packaging, transporting, and storing food that is never consumed. When food decomposes, it can also release methane, a potent greenhouse gas.
If your workplace provides catering or operates a cafeteria, consider:
Tracking food waste to identify patterns
Ordering more accurately
Offering smaller portions with the option for refills
Donating safe surplus food where possible
Composting food scraps
Using food waste for animal feed or other recovery programs where available
The UN Food and Agriculture Organization estimates that around one-third of food produced globally is lost or wasted.
5. Build a paperless culture
Most routine business documents can be shared and stored digitally. A paperless policy can reduce paper, printing, ink, storage, and equipment costs while supporting collaboration and document security.
Encourage digital signatures, cloud-based filing, electronic invoicing, and default double-sided printing when printing is unavoidable.
6. Make recycling easy
Employees are more likely to recycle correctly when bins are clearly labelled, conveniently located, and consistent across the workplace.
Provide separate collection points for relevant materials, such as paper, cardboard, plastics, glass, cans, food waste, batteries, and electronics. Share simple instructions so employees know what can and cannot be recycled locally.
7. Replace single-use cups, plates, and cutlery
Single-use coffee cups, plastic glasses, disposable plates, and cutlery create unnecessary waste. Replace them with reusable mugs, glasses, dishes, and silverware in kitchens and break rooms.
For larger offices, purchasing reusable dining ware in bulk is often affordable and can significantly reduce disposable-material use.
8. Make office coffee more sustainable
Coffee can create waste through single-use capsules, disposable cups, packaging, and grounds. Reduce its impact by:
Choosing Fairtrade or responsibly sourced coffee
Avoiding non-recyclable capsules
Using reusable filters or recyclable systems where possible
Composting coffee grounds through a commercial composting service
Providing reusable mugs rather than disposable cups
9. Encourage greener commutes and hybrid work
Support employees who walk, cycle, use public transport, carpool, or drive electric vehicles. Hybrid schedules can reduce the number of commuting days while helping organizations lower office operating costs.
The right approach will depend on employee needs, local transit options, and the nature of the work.
10. Use rechargeable batteries
Many office tools and devices use batteries, including remote controls, calculators, alarms, and small appliances. Rechargeable batteries can be reused hundreds of times, reducing both waste and purchasing costs.
11. Review office energy use regularly
Assess how energy is used across the workplace. Look for opportunities to improve lighting, heating, cooling, IT equipment, kitchen appliances, and out-of-hours power use.
Simple actions—such as switching off monitors, using power-saving settings, and shutting down unused equipment—can add up across a large workforce.
12. Provide responsibly sourced food and drinks
When supplying food and beverages, choose organic, local, seasonal, Fairtrade, or responsibly produced options where feasible. These choices can support more sustainable farming methods and fairer conditions for producers.
13. Replace bottled water with filtered tap water
Single-use water bottles create plastic waste and carry emissions from manufacturing and transportation. Installing a water filter or refill station can reduce waste, lower costs, and provide employees with an ongoing water supply.
14. Make business travel part of your office sustainability strategy
Business travel can be a significant contributor to corporate emissions. A greener office strategy should include a plan for reducing travel emissions through better trip planning, lower-carbon transport, sustainable accommodation, and a clear sustainable travel policy.
How to reduce your carbon footprint from business travel
Business travel is often essential for building relationships, serving customers, attending events, and closing deals. The goal is not necessarily to eliminate travel altogether, but to make every trip more purposeful and lower in emissions.
Calculate business-travel emissions
Start by measuring emissions from flights, rail journeys, hotels, rental cars, taxis, and other travel services. This creates a baseline and helps identify the routes, travel types, and departments with the greatest impact.
A centralized travel platform can make this process easier by providing visibility into travel spending and emissions. With Perk, companies can track the carbon impact of corporate travel and support their sustainability goals through Green Trip.
Create a green business travel program
A green travel program sets out how a company will reduce travel-related emissions while meeting business needs. It should include:
A baseline carbon assessment
Clear reduction targets
Preferred travel modes and suppliers
Guidance on when travel is necessary
Approval processes for higher-emission trips
Responsibilities for managers, travellers, and program owners
Regular reporting and review
Policies work best when they are straightforward enough for employees to follow in the booking process.
Choose rail and public transport where practical
Rail travel generally produces fewer emissions than flying, particularly for shorter routes. When train journeys are practical in terms of journey time, cost, and accessibility, make rail the preferred option.
For local travel, encourage public transit, walking, cycling, and shared transport instead of individual car journeys or short flights.
Fly less, fly direct, and choose economy class
When flights are necessary, reduce emissions by:
Avoiding unnecessary trips through virtual meetings where appropriate
Choosing direct flights rather than itineraries with layovers
Booking economy class where practical
Selecting lower-emission flight options when available
Combining multiple meetings into one trip
Take-off and landing are fuel-intensive, so avoiding connections can reduce emissions. Seating class matters too: first-class and business-class seats can generate substantially more emissions per passenger than economy seats because they occupy more space and often involve higher luggage allowances.
Choose lower-emission airlines
Emissions can differ between airlines on the same route. When evaluating airlines, consider:
Emissions shown for the individual flight
Fleet age and fuel efficiency
Aircraft type and load factors
Whether the airline has transparent sustainability reporting
Whether it uses credible sustainable aviation fuel initiatives or other verified reduction measures
Whether it offers quality carbon-credit options for residual emissions
Avoid relying solely on marketing claims. Look for evidence of measurable action and transparent reporting.
Choose sustainable accommodation
Hotels use energy for heating, cooling, lighting, laundry, food service, and guest amenities. Add sustainable accommodation criteria to your travel program, such as recognized environmental certifications, energy-efficiency initiatives, water-conservation measures, waste-reduction practices, and accessible public transport.
Travellers can also reduce hotel-related impact by reusing towels, declining unnecessary daily linen changes, and choosing properties close to meeting locations or transit links.
Reduce car-rental and ground-transport emissions
Where road travel is needed, choose electric or hybrid rental vehicles when possible. For conventional vehicles, select fuel-efficient models and avoid oversized rentals.
Encourage employees to use public transport, shared rides, walking, and cycling for local journeys when safe and practical.
Use relevant green travel tax incentives
Some jurisdictions offer tax breaks or incentives for low-emission vehicles, public-transport benefits, cycling schemes, and other sustainable initiatives. Consult a tax professional or relevant local authority to understand which benefits may apply to your organization.
How to create a sustainable travel policy
A sustainable travel policy gives employees practical guidance for making lower-carbon choices. It also helps travel managers apply consistent rules, monitor results, and align travel decisions with wider business goals.
Step 1: Calculate current travel emissions
Measure current emissions from flights, rail, hotels, cars, and other travel services. If your organization has a sustainability team, it may already have emissions data. If not, a travel management company or booking platform can help provide a baseline.
Step 2: Identify the biggest opportunities
Review the data to identify the routes, travel categories, or teams responsible for the highest emissions. Consider both absolute emissions and efficiency measures, such as emissions per trip, employee, kilometre, or revenue.
Also assess cost. A sustainable travel policy should be realistic and support commercial needs rather than creating unworkable restrictions.
Step 3: Establish clear travel rules
Your policy may include measures such as:
Rail is required instead of air travel for journeys below a defined travel-time threshold.
Direct flights are preferred when flying is necessary.
Economy class is the standard for most trips.
Preferred airlines and hotels must meet defined environmental criteria.
Public transport is preferred for local travel.
Electric or hybrid vehicles are preferred for car rental.
Travel approvals are required for high-emission or avoidable trips.
Employees should combine meetings or extend trips only when this reduces total travel.
The policy should explain when exceptions are allowed, who approves them, and how travellers can book compliant options.
Step 4: Build the policy into booking tools
Policies are easier to follow when they are integrated into the booking process instead of hidden in a PDF or shared drive.
An online booking tool can show compliant options, automate approvals, and flag bookings that need further review. Perk helps travel managers incorporate policy rules into travel booking and gives travellers visibility into lower-carbon options through Green Trip.
Step 5: Communicate in clear, practical language
Employees do not need to become carbon-accounting experts to follow a sustainable travel policy. Give them simple, actionable rules and explain the purpose behind them.
For example: “Choose rail for journeys under five hours where available,” is easier to apply than a complex emissions formula.
Step 6: Encourage adoption with incentives and feedback
Positive reinforcement can help sustainability become part of travel culture. Consider recognizing teams that make measurable improvements, highlighting successful lower-carbon travel choices, or creating friendly competition between departments.
Gather feedback from frequent travellers, travel arrangers, and managers. If a policy is difficult to follow in practice, adjust it rather than expecting employees to work around it.
Step 7: Measure, report, and improve
Review travel emissions regularly. Share progress, celebrate reductions, and revise the policy as routes, suppliers, business needs, and technology change.
Sustainability is an ongoing process. A policy should evolve as the company learns what works.
What are carbon offsets?
Even after reducing emissions, some residual emissions may remain. Carbon offsets, also called carbon credits, are intended to compensate for emissions by funding projects that reduce, avoid, or remove greenhouse gases elsewhere.
Typically, one carbon credit represents one metric tonne of carbon dioxide equivalent. Projects may include:
Forest conservation and reforestation
Methane capture
Renewable-energy generation
Energy-efficiency projects
Regenerative agriculture
Direct carbon capture
Clean cooking or biogas programs
Offsets should not be treated as permission to continue avoidable emissions. They are most credible when used after a company has made meaningful efforts to measure, avoid, and reduce its own footprint.
How do carbon offsets for flights work?
Flight offsets are designed to compensate for emissions associated with air travel. First, the flight’s estimated emissions are calculated. The traveller or company then purchases credits intended to support emissions-reduction or carbon-removal projects.
Flight emissions vary based on factors such as:
Distance and route
Aircraft type
Cabin class
Passenger load
Stopovers and connections
Cargo allocation
Fuel consumption
Altitude and operational conditions
No calculator can provide a perfectly exact number for every flight, but detailed calculators can produce estimates that support more informed choices.
Companies can buy flight offsets in several ways:
Through an airline: Some airlines offer an offset option during booking.
Through a travel-management platform: Perk’s Green Trip program can help companies offset emissions associated with flights, rail, hotels, and other bookings made through the platform.
Directly from a project developer or offset provider: This can offer more control over the projects supported, but requires more due diligence and administration.
What to look for in a reliable carbon offset program
Carbon markets vary in quality. To reduce greenwashing risk, evaluate the projects, standards, methodology, reporting, and governance behind any carbon-credit purchase.
A credible carbon offset program should demonstrate:
Additionality: The project would not have happened without carbon-credit funding.
Measurability: Emissions reductions or removals are calculated using a clear methodology.
Verification: An independent third party validates and verifies the project.
Permanence: The claimed climate benefit is designed to last, with risks managed appropriately.
No double counting: The same credit is not claimed by multiple parties.
Transparency: The provider shares project details, standards, credit retirements, and reporting.
Community benefits: Projects should respect local communities and, where possible, create social and environmental co-benefits.
Look for credits verified through recognized standards and registries, including Verra, Gold Standard, the American Carbon Registry, Climate Action Reserve, Plan Vivo, and Climate, Community & Biodiversity Standards.
Do airlines offer carbon offsets?
Many airlines have offered carbon-credit options during the booking process or through loyalty programs. Examples have included:
Qantas: Its Future Planet program has offered offset options and frequent-flyer points for contributions.
Delta: Delta has offered carbon-offsetting initiatives for customers.
United: United has operated its Eco-Skies CarbonChoice program in partnership with Conservation International.
Cathay Pacific: Cathay Pacific has offered its Fly Greener program.
KLM: KLM has operated CO2ZERO initiatives.
China Airlines: China Airlines has offered carbon-contribution options.
Lufthansa: Lufthansa has partnered with myclimate on climate-protection projects.
Airline programs can change frequently. Before selecting one, review the project type, carbon-credit standard, third-party verification, retirement process, and how the airline reports the use of funds.
How much do carbon offsets cost?
Offset costs vary widely by project type, location, verification standard, supplier, and credit quality. Costs may also vary depending on flight class, distance, and calculation methodology.
Be cautious of choosing credits based solely on price. Higher-quality projects may involve more robust verification, stronger community safeguards, greater permanence protections, or more expensive technologies. The key question is whether the program provides credible, transparent evidence of real climate impact.
Are carbon offsets tax-deductible?
Tax treatment varies by country and by the structure of the payment. In some jurisdictions, a contribution may be tax-deductible when it is made as a donation to an eligible nonprofit organization; in others, it may be treated as a business expense or may not qualify for a deduction at all.
Consult a qualified tax professional for advice based on your company’s location and the specific carbon-credit provider.
Make sustainability part of how your business operates
Reducing your business carbon footprint does not require a single dramatic transformation. It requires consistent, evidence-based decisions: measure emissions, reduce waste, use energy more efficiently, make lower-carbon travel choices, engage employees and suppliers, and use verified carbon credits carefully for unavoidable emissions.
The most successful companies treat sustainability as an ongoing operational discipline rather than a one-time campaign. Every lower-emission trip, efficient appliance, reusable product, renewable-energy contract, and well-designed policy can move your organization closer to a more resilient and responsible future.
