How businesses can reduce their carbon footprint: a practical guide

20 MIN READ

Reducing your company’s carbon footprint is no longer just a nice-to-have. Customers, employees, investors, and regulators increasingly expect businesses to understand and reduce their environmental impact.

Whether you run a small office, a growing company, or a global organization, meaningful emissions reductions start with knowing where your emissions come from and making practical changes across operations, workplaces, commuting, and business travel.

This guide explains how to measure your footprint, reduce emissions at the source, create a sustainable travel policy, improve office operations, and use high-quality carbon offsetting for emissions that cannot yet be avoided.

What does a business carbon footprint mean?

A carbon footprint is the total greenhouse gas emissions associated with an activity, product, person, or organization. While the term often refers to carbon dioxide (CO₂), a complete footprint may also account for other greenhouse gases, such as methane.

For a business, emissions can come from far more than energy use in an office. Consider a simple bottle of water consumed at work: its footprint can include sourcing the water, manufacturing the bottle, packaging, transportation, retail operations, and waste handling.

Business emissions are commonly grouped into three categories:

  • Scope 1: Direct emissions from sources your company owns or controls, such as company vehicles or on-site fuel use.

  • Scope 2: Indirect emissions from purchased energy, including electricity, heating, cooling, or steam.

  • Scope 3: Other indirect emissions across your value chain, such as business travel, employee commuting, purchased goods, freight, waste, and suppliers.

For many organizations, Scope 3 emissions represent a substantial share of their total footprint. That makes business travel, employee commuting, procurement, and supplier decisions important parts of any sustainability strategy.

Why should businesses reduce carbon emissions?

Reducing emissions helps limit climate change, protects natural resources, and can make business operations more efficient. It can also deliver commercial benefits, including:

  • Lower energy, fuel, waste, and materials costs

  • Stronger brand reputation and customer trust

  • Greater employee engagement and retention

  • Better preparedness for reporting requirements and environmental regulations

  • More resilient supply chains and business operations

  • Progress toward corporate social responsibility, ESG, and net-zero goals

The most effective approach is not to treat sustainability as a one-off project. It should become part of how your company makes purchasing, travel, facilities, and operational decisions.

The role of sustainability managers

A sustainability manager helps a company understand its environmental impact and turn commitments into measurable action. Their responsibilities may include:

  • Measuring greenhouse gas emissions and identifying major sources

  • Setting emissions-reduction targets

  • Developing sustainability policies and implementation plans

  • Working with procurement, finance, HR, facilities, and travel teams

  • Educating employees and improving policy compliance

  • Evaluating suppliers, energy providers, and environmental projects

  • Monitoring progress and supporting environmental reporting

However, sustainability should not sit with one person or department alone. Lasting progress requires clear ownership across the organization, from leadership and finance teams to office managers, travelers, and employees.

How to reduce your company’s carbon footprint

1. Measure your current carbon footprint

You cannot manage what you do not measure. Start by calculating your company’s greenhouse gas emissions and identifying the activities responsible for the largest share.

Depending on your business, this may include:

  • Electricity, heating, and cooling

  • Company vehicles and fuel consumption

  • Manufacturing and freight

  • Business travel

  • Employee commuting

  • Office supplies, food, and equipment

  • Waste and recycling

  • Digital infrastructure, servers, and web hosting

  • Purchased goods and supplier activity

A sustainability consultancy can help organizations conduct a detailed footprint assessment, develop a reduction plan, support implementation, provide training, and help pursue relevant sustainability certifications. Companies can also use emissions-management tools and data from travel, fleet, energy, and procurement systems.

When measuring business travel, use a consistent methodology and track emissions by route, transport type, traveler, department, and booking class. A platform such as Perk’s business travel solution can help organizations view and report on travel-related emissions while trips are being planned and booked.

2. Set clear, realistic reduction targets

Once you know your baseline, set targets that reflect your highest-impact emissions sources. Rather than launching broad initiatives with no measurable outcome, prioritize areas where your business can make the largest difference.

For example, your goals could include:

  • Reducing electricity consumption per employee

  • Moving to renewable electricity

  • Cutting air-travel emissions per trip or per employee

  • Increasing rail travel for shorter journeys

  • Reducing waste sent to landfill

  • Lowering fuel use across your vehicle fleet

  • Reducing paper and single-use products

  • Improving recycling rates

  • Reducing emissions from key suppliers

Growing businesses may find it useful to start with intensity metrics, such as emissions per employee, per kilometer traveled, or per unit produced. These metrics can show progress even as the company expands.

Review targets regularly and adjust them as data quality, operational needs, and available technologies improve.

3. Apply the three Rs: reduce, reuse, recycle

The three Rs remain a practical starting point for reducing waste and resource use:

  1. Reduce unnecessary purchasing, packaging, energy use, travel, and disposable products.

  2. Reuse equipment, furniture, packaging, supplies, and materials whenever possible.

  3. Recycle materials that cannot be reduced or reused, using clearly labeled waste streams.

Apply these principles to office supplies, packaging, food service, IT equipment, procurement, and operational processes. Reducing the amount of material you buy is usually more effective than recycling it after use.

4. Choose renewable energy and improve energy efficiency

Switching to renewable electricity can significantly reduce emissions associated with your energy use. First, ask your existing utility provider whether it offers a verified renewable-energy tariff or procurement option. If not, consider changing providers or exploring other renewable-energy purchasing arrangements available in your market.

Energy efficiency should happen alongside renewable-energy procurement. Reducing wasted energy lowers costs and makes your sustainability efforts more durable.

Key actions include:

  • Upgrading to energy-efficient appliances and office equipment

  • Replacing outdated lighting with LEDs

  • Installing occupancy sensors and dimmable lights

  • Optimizing heating, ventilation, and air conditioning systems

  • Improving insulation and temperature controls

  • Maintaining equipment to avoid energy waste

  • Maximizing natural light where possible

  • Turning off equipment when it is not in use

When purchasing new equipment, compare energy-efficiency ratings as well as upfront price. Efficient appliances often lower operating costs over their lifetime.

5. Make your office more sustainable

An office can produce emissions through energy use, waste, food, water, supplies, and employee commuting. Small operational changes can add up, especially when they become part of everyday behavior.

Use efficient lighting, heating, and cooling

Lighting, heating, and air conditioning are major energy uses in many workplaces. Upgrade old fixtures to LEDs, use motion sensors in low-traffic spaces, and use blinds or shades that allow employees to make better use of daylight.

Review thermostat settings and building controls to balance employee comfort with energy efficiency. Regular maintenance of heating and cooling systems can reduce energy consumption while helping create a more comfortable workplace.

Reduce food waste

An estimated one-third of food produced globally is lost or wasted, according to the UN Food and Agriculture Organization. Food waste represents not only discarded meals, but also wasted land, water, energy, packaging, and transportation. When food decomposes, it can also produce methane.

If your workplace provides food, reduce waste by improving demand forecasting, offering flexible portion sizes, donating suitable surplus food where permitted, and arranging composting or food-waste collection. Where food cannot be donated, composting or conversion into animal feed and other products may be preferable to landfill disposal.

Build a paperless culture

Most business documents no longer need to be printed. Digital workflows can reduce paper use, printing costs, storage needs, and administrative work while improving organization, collaboration, and document security.

Create a paperless policy that encourages employees to use digital signatures, cloud storage, shared documents, digital invoices, and electronic approval workflows. For documents that must be printed, use double-sided printing and recycled paper.

Improve recycling systems

Make recycling easy rather than expecting employees to figure it out themselves. Place enough recycling bins in convenient locations, use clear signs showing what belongs in each stream, and ensure your waste provider can process the materials you collect.

Track contamination levels where possible. If recyclable materials repeatedly end up in general waste, update signs, provide employee education, or simplify the recycling setup.

Replace single-use products

Single-use coffee cups, plates, glasses, cutlery, water bottles, and food containers create unnecessary waste. Provide reusable mugs, glasses, dishes, and utensils in kitchens and break rooms instead.

For larger workplaces, purchasing reusable dining ware in bulk can be cost-effective. Reusable options are particularly valuable when paired with adequate dishwashing facilities and clear expectations for use.

Make office coffee more sustainable

Coffee can create waste through disposable cups, non-recyclable capsules, packaging, and coffee grounds. Improve your office coffee setup by:

  • Choosing Fairtrade or responsibly sourced coffee where possible

  • Avoiding non-recyclable single-use coffee capsules

  • Using reusable mugs rather than disposable cups

  • Composting coffee grounds through a local or corporate composting service

  • Buying coffee in larger, lower-packaging formats where appropriate

Replace bottled water with filtered water

Providing filtered tap water can reduce plastic waste, transportation emissions, and costs associated with bottled water. Install water filters or dispensers where needed and encourage employees to use refillable bottles.

6. Choose more sustainable suppliers and web hosting

Your company’s purchasing decisions can influence a significant portion of its Scope 3 footprint. Evaluate suppliers based on environmental practices as well as price, quality, and reliability.

Look for suppliers that can demonstrate:

  • Energy-efficiency and emissions-reduction programs

  • Recycled, recyclable, or lower-impact packaging

  • Responsible material sourcing

  • Waste-reduction and circular-economy practices

  • Transparent environmental reporting

  • Credible certifications where relevant

Digital infrastructure also has an environmental impact. If you use externally hosted servers, consider the energy required to run them and the source of that energy. Sustainable web-hosting providers may combine energy-efficient infrastructure, renewable electricity, efficient hardware, and credible climate programs.

7. Reduce fleet and road-travel emissions

For organizations with vehicle fleets, road emissions can be substantial. Improve efficiency by reviewing the type of vehicles you operate, how often they are used, and whether trips can be reduced or consolidated.

Consider:

  • Replacing older vehicles with fuel-efficient, hybrid, or electric models

  • Choosing smaller vehicles where they meet operational needs

  • Optimizing routes and delivery schedules

  • Reducing idling time

  • Encouraging car sharing and ride pooling

  • Training drivers in fuel-efficient driving techniques

  • Using public transport or rail where it is practical

Electric vehicles can reduce tailpipe emissions, but their total environmental benefit depends on the electricity source and vehicle use. Where electrification is not yet feasible, fuel-efficiency measures can still reduce emissions and operating costs.

8. Promote greener employee commutes

Employee commuting can be a meaningful emissions source, especially for office-based organizations. Support lower-carbon commuting through practical policies and incentives.

Options include:

  • Subsidized or free public-transport passes

  • Secure bike storage, showers, and changing facilities

  • Bicycle-purchase or bike-leasing programs

  • Carpooling programs

  • Charging infrastructure for electric vehicles

  • Flexible start times that make public transport easier to use

  • Hybrid and remote-work arrangements

A hybrid schedule can reduce commuting emissions and office energy use while supporting work-life balance. The most appropriate approach will depend on employee roles, local transport infrastructure, and business needs.

9. Educate and engage employees

Employees make many day-to-day decisions that affect your company’s environmental footprint. They choose how they commute, travel, print, dispose of waste, use energy, and purchase supplies.

Make sustainability education ongoing rather than a single launch announcement. Use simple, practical guidance that explains what employees should do and why it matters.

Effective engagement methods include:

  • Onboarding training

  • Short sustainability updates in company meetings

  • Clear office signage and reminders

  • Department-level emissions or waste goals

  • Friendly competitions between teams

  • Recognition for employees who make sustainable choices

  • Feedback channels for improving policies

Avoid overwhelming employees with complex technical data. Give them clear actions they can take, explain how those actions support company goals, and share progress regularly.

How to reduce the carbon footprint of business travel

Business travel is often necessary for building relationships, attending events, serving customers, and completing work that cannot be done remotely. But it can also be a major source of Scope 3 emissions.

The goal is not necessarily to eliminate every trip. It is to make each trip more intentional and lower carbon where possible.

1. Measure business travel emissions

Start by calculating the emissions associated with your flights, rail journeys, hotels, car rentals, and other travel services. This helps identify high-emission routes, frequent travelers, travel classes, and trip types.

A travel-management platform can make this easier by showing emissions data at the point of booking and producing reports for travel managers and sustainability teams. This data can then guide policy decisions, supplier choices, and reduction targets.

2. Create a sustainable business travel policy

A sustainable travel policy gives employees clear guidance on how to make lower-emission travel choices while balancing cost, safety, traveler well-being, and business needs.

A strong policy should define:

  • When travel is necessary and when virtual meetings are appropriate

  • When rail should be selected instead of air travel

  • Preferred airlines, rail operators, hotels, and car-rental providers

  • Rules for direct flights and layovers

  • Permitted travel classes

  • Low-emission ground-transport options

  • Requirements for tracking and reporting emissions

  • The approval process for exceptions

  • Whether and how residual travel emissions are addressed through carbon credits

For a detailed framework, use a sustainable travel policy template to structure your company’s requirements and responsibilities.

3. Choose rail and public transport where possible

Rail is often a lower-emission alternative to flying, particularly for shorter intercity journeys. A policy can require rail travel when the journey time falls below a specified threshold, provided it is practical and safe.

For local travel, encourage public transport, walking, cycling, or shared low-emission transport rather than individual taxis or rental cars. Public transport can also improve the travel experience by avoiding traffic, parking, and airport processes.

4. Fly less, fly direct, and travel in economy class

When flying is necessary, reduce emissions by choosing direct routes where possible. Takeoff and landing are energy-intensive parts of a journey, so avoiding unnecessary layovers can reduce emissions and shorten travel time.

Seat class also affects emissions allocation. First- and business-class seats generally occupy more space per passenger and can be associated with higher per-passenger emissions than economy seating. For short- and medium-haul travel, encouraging economy class can be a practical and cost-effective policy choice.

5. Choose lower-emission airlines and newer aircraft

Emissions can vary between airlines operating the same route due to aircraft type, seating density, load factors, operational efficiency, and fleet age.

When selecting preferred airlines, consider:

  • Flight-specific emissions information

  • Fleet efficiency and use of newer aircraft

  • Sustainability commitments and reporting

  • Investment in lower-carbon aviation technologies

  • Whether the airline offers credible emissions-reduction or carbon-credit options

Employees should not have to research this independently every time they book. Build preferred choices into your travel policy and booking process where possible.

6. Choose sustainable accommodation

Hotels consume energy, water, food, laundry services, and disposable products. Accommodation can therefore be a significant part of a trip’s footprint, particularly on longer stays.

Look for hotels that demonstrate credible environmental practices, such as energy-efficiency programs, renewable-energy use, waste reduction, water conservation, and recognized sustainability certifications. Include preferred sustainable accommodations in your travel policy where possible.

7. Choose lower-emission ground transport

The lowest-emission option will vary by route, vehicle, occupancy, and local infrastructure. In many cases, rail and public transport are preferable to flying or driving. Where a car is necessary, consider hybrid or electric rental vehicles, smaller vehicles, and shared journeys.

For teams traveling together, a shared car may reduce emissions per person compared with separate vehicles. Encourage travelers to compare options rather than assuming one transport mode is always best.

8. Use green travel tax incentives where available

Depending on where your company operates, you may be eligible for tax incentives related to low-emission vehicles, public-transport support, employee cycling schemes, commuting benefits, or environmental donations.

Rules differ by country and can change over time, so seek advice from a qualified tax professional before relying on any incentive or deduction.

How to create and implement a sustainable travel policy

A travel policy only reduces emissions if employees understand it and can follow it in practice.

Calculate your baseline

Use travel data to establish current emissions by route, department, traveler, transport type, and booking class. Identify the routes and decisions that create the largest share of emissions.

Evaluate the biggest opportunities

Look for practical changes that can reduce emissions without compromising essential business activity. For example:

  • Replacing short-haul flights with rail

  • Reducing trips with multiple stopovers

  • Moving from premium cabins to economy for short trips

  • Choosing preferred lower-emission suppliers

  • Consolidating multiple meetings into a single trip

  • Replacing some internal travel with virtual meetings

Include cost in the analysis. A sustainable policy must be realistic enough for teams to use consistently.

Create simple, actionable rules

Employees are more likely to comply with straightforward policies. Rather than focusing only on emissions figures, state what travelers should do.

Examples include:

  • Choose rail instead of air travel for journeys below a set duration.

  • Book direct flights where practical.

  • Use economy class for short- and medium-haul flights.

  • Select approved hotels with recognized sustainability practices.

  • Use public transport, rail, or low-emission vehicles for ground travel.

  • Book through the company’s approved travel platform so emissions can be tracked.

  • Request approval for exceptions before booking.

Build sustainability into the booking process

Policies are easier to follow when sustainable options are visible at the point of booking. An online booking platform can guide travelers toward compliant options, automate approvals for in-policy trips, and flag bookings that need manager review.

Tools such as Perk’s travel booking platform can help travel managers apply policy parameters while giving employees visibility into the available travel choices.

Motivate teams and invite feedback

Communication should explain why the policy exists and what employees can do differently. Consider recognizing teams that make measurable progress or highlighting examples of employees who make thoughtful lower-carbon choices.

Review the policy regularly. Ask travelers where the policy is difficult to follow, identify routes where sustainable alternatives are limited, and adjust requirements where necessary.

Carbon offsetting: how it fits into a reduction strategy

Carbon offsetting should not replace emissions reduction. The most credible approach is to avoid unnecessary emissions, reduce the emissions you can control, and then consider high-quality carbon credits for residual emissions that cannot yet be eliminated.

Carbon credits generally represent a quantified reduction or removal of greenhouse gas emissions. Businesses purchase credits to support projects such as forest conservation, methane capture, renewable energy, direct carbon removal, or regenerative agriculture.

The quality of carbon-credit projects varies significantly. Poor-quality projects can create reputational risk and lead to greenwashing concerns, so careful due diligence is essential.

What to look for in a credible carbon offset program

A reliable program should provide evidence that its projects are:

  • Additional: The emissions reduction would not have happened without the project funding.

  • Measurable: Emissions reductions are quantified using a clear methodology.

  • Verified: Independent third parties validate or verify the project.

  • Permanent: The claimed climate benefit is designed to last, with safeguards for reversal risks where relevant.

  • Transparent: The program clearly explains where funds go, how credits are issued, and what projects deliver.

  • Beneficial to communities: Projects should avoid harm and, where possible, create social and environmental co-benefits.

  • Properly governed: Projects should be monitored, professionally managed, and independently assessed.

Look for recognized standards and registries, such as Verra, the Gold Standard, the American Carbon Registry, the Climate Action Reserve, or Plan Vivo.

How are flight emissions calculated?

Flight emissions estimates vary because they depend on several factors, including:

  • Distance traveled

  • Route and altitude

  • Aircraft type

  • Passenger load factor

  • Cabin class

  • Stopovers

  • Fuel use

  • Taxi time and operational conditions

No calculator can capture every variable perfectly, but a robust methodology should provide a consistent and reasonable estimate. Use the same methodology across your travel program so you can compare trips and monitor progress over time.

How much do carbon offsets cost?

Prices vary widely depending on project type, location, verification standards, credit quality, and whether the project focuses on emissions avoidance, reduction, or removal.

Credits are often priced per metric tonne of CO₂e. A lower price does not necessarily mean better value: high-quality projects with robust verification, community safeguards, and durable climate benefits can cost more.

For business travel, consider an integrated solution such as Green Trip, which helps companies calculate travel emissions and support certified environmental projects through their travel program.

Can airlines help travelers offset flight emissions?

Many airlines offer an emissions-calculation or carbon-credit option during the booking process. These programs vary in quality, cost, methodology, and project selection, so companies should review them carefully before including them in a travel policy.

Examples of airlines that have offered carbon-related programs include:

  • Qantas, through its Future Planet program

  • Delta, which has offered carbon-offsetting options for travelers

  • United, through its Eco-Skies initiatives

  • Cathay Pacific, through its Fly Greener program

  • KLM, through CO₂-related climate initiatives

  • China Airlines, which has offered passenger contribution options

  • Lufthansa, which has partnered with climate-protection providers including myclimate

Airline programs can be convenient, but they should be evaluated against the same standards as any other carbon-credit provider. Companies should prioritize reducing flight emissions first through fewer trips, direct flights, lower-emission transport modes, and travel-policy controls.

Are carbon offsets tax-deductible?

Tax treatment varies by country and depends on the nature of the payment and the legal status of the recipient organization. In some cases, a carbon-credit purchase may be treated as a business expense; in others, a contribution may qualify as a charitable donation only if the recipient is an eligible nonprofit organization.

For example, in the United States, a payment may be deductible as a charitable contribution only when it meets applicable requirements, including support for a qualified organization. Businesses should consult a qualified tax adviser rather than assuming that all carbon-credit purchases are deductible.

Build a lower-carbon business, one decision at a time

There is no single action that will eliminate a company’s environmental impact. The strongest sustainability programs combine accurate measurement with practical emissions reductions across energy, offices, procurement, transport, employee behavior, and business travel.

Start with the changes that matter most for your organization. Track results, improve your policies, engage employees, and use high-quality carbon credits carefully for emissions that remain.

For companies with regular travel activity, a clear travel policy, reliable emissions data, and tools such as Green Trip can help make lower-carbon business travel easier to manage and more transparent.
