How a Coworking Space Can Measure and Cut Its Carbon Footprint

A coworking space can measure its carbon footprint with the bills it already receives. Pick a boundary, gather a year of energy, waste and travel data, then convert each item with an emission factor. The result shows where the emissions are, so you can spend effort on the few things that matter most.

What counts toward a coworking space's footprint?

A carbon footprint is the greenhouse gas emissions caused by an activity, usually stated as tonnes of carbon dioxide equivalent (CO2e). The GHG Protocol Corporate Standard, the most widely used accounting method, splits emissions into three scopes:

• Scope 1: direct emissions from sources you own or control, such as a gas boiler or a company vehicle.
• Scope 2: emissions from the electricity, heat or cooling you buy.
• Scope 3: other indirect emissions, such as waste, purchased goods and the travel of members and staff.

If you lease your space, your landlord may own the boiler, which can move some heating into another party's Scope 1. Decide which way you will count it and keep to it every year.

How do I set the boundary?

Decide what is in and what is out before you collect anything. A sensible first boundary for a small operator is the space itself: electricity, heating fuel, water, waste and the supplies you buy. Member commuting is harder to measure and can be added later with a short survey.

Pick a 12-month period so seasons do not skew the result, and write the boundary on the first page of your spreadsheet.

What data should I collect?

1. Electricity: kWh from 12 months of bills.
2. Heating fuel: gas, oil or district heat from bills or meter readings.
3. Waste: how much goes to landfill, recycling and compost, from your collector's records or an estimate by bin size.
4. Water: volume from bills.
5. Travel (optional): a member and staff survey on how people get to the space.

Where you only have an estimate, label it as an estimate so nobody mistakes it for a measurement.

How do I turn bills into emissions?

Multiply each activity amount by an emission factor, which is the emissions per unit of that activity. For electricity, that means kWh used multiplied by the factor for your grid. In the US, the EPA's GHG Emission Factors Hub lists factors for fuels, electricity and more. Other countries publish their own, so use the set that matches your location and year.

Add the results by scope. EPA also has guidance on Scope 1 and Scope 2 inventories if you want to check your method.

What do the results tell me?

Sort the totals from biggest to smallest. For many office-type spaces, heating, cooling and electricity dominate, but your building and climate may differ, so look at your own numbers rather than assuming. Focus on the top one or two items first. Cutting a small category to zero helps less than trimming a large one.

Which reductions should I try first?

Cut energy use

Swap remaining lights for LEDs, add timers or occupancy sensors, set sensible heating and cooling schedules, and make sure shared monitors and printers go to sleep after hours. The ENERGY STAR buildings resources include tools and guidance for benchmarking and saving energy in commercial space.

Choose cleaner power

Ask your supplier about a renewable tariff, or ask your landlord whether on-site generation is planned. This changes your Scope 2 figure without changing how the space runs.

Reduce waste

Set up clearly labelled recycling, replace single-use cups with a shared set, and review what the kitchen throws away each week.

Make travel easier

Bike storage, showers and clear transit directions on your site remove barriers for members who would prefer not to drive.

How should I share the numbers?

Publish the boundary, the year, the factors you used and the totals, plus what you plan to change. Plain honesty about gaps builds more trust than a large claim. Repeat the measurement each year with the same method so the trend is meaningful.

Running the space well often goes hand in hand with this. Our piece on hosting workshops in a coworking space shows how events use the room, which is useful when you estimate occupancy and energy peaks. For members' own setups, the portable home office kit guide covers equipment that travels with them.

Where should I start this month?

Collect twelve months of electricity and heating data, build a one-page spreadsheet and apply the factors. A rough first footprint is more useful than a perfect one that never happens, and you can refine it next year.
