Your net zero plan

Understand your business emissions

1. What causes emissions

In addition, Mobile Network Operators (MNOs) and other large businesses are asking their suppliers to calculate their emissions and reduce them.

Many large businesses are collaborating with their suppliers to help them meet new environmental requirements in the procurement process. 

Large businesses are helping suppliers to:

• prepare a Carbon Reduction Plan (CRP): a document that summarises current emissions and plans for reducing these
• identify onsite energy reduction opportunities and improve GHG reporting
• balance improvements in computational power with emission reduction in new products
• sell and design lower carbon and circular products that maximise longevity through repairability, modularity and reuse

Find out about BT’s Climate Change Procurement Standard and how Vodafone manages its supply chain.

Visit how to become a ‘net-zero’ ready supplier to find out more about the procurement process and CRPs.

3. Use free tools to calculate your emissions

Collect data for a 12-month period for the main activities which release carbon emissions in your organisation.

Choose one of the free carbon calculators to help record your calculate emissions in metric tonnes per year. 

This will give you an emissions baseline which serves as a foundation for understanding your current emissions.

You can use this as a reference point against which you can:

• identify where your emission hotspots 
• measure changes in your greenhouse gas (GHG) emissions going forward

Visit Measure your carbon emissions to find out more about what data is required and how to get started.

As a final step, you could also consider hiring a sustainability consultant.

4. Sign up for the SME Climate Commitment

Make a public commitment to achieve net zero by 2050 or earlier. 

You can sign up to the SME Climate Commitment. 

To align with the SME Climate Commitment, enterprises will need to do their utmost to cut their greenhouse gas emissions by at least 50% before 2030, using 2019 or later as the base year. 

This means that Scope 1 and Scope 2 emissions must be cut in half by 2030 at the latest. Businesses should also aim to halve their most material Scope 3 emissions by 2030.

You can publish your commitment on your website and in reports to:

• let your stakeholders know your targets
• show customers you are committed to reducing emissions

Take action right now

This quick wins section identifies actions you can take right now to reduce your carbon emissions.

1. Change your lighting

Lighting consumes 20% of all energy generated in the UK and is a major cost for SMEs in office spaces. Change to LED bulbs to significantly reduce your energy use. 

Find out more about how you can save on lighting.

2. Change your energy tariff

Switch to a green energy tariff with your energy supplier. This will reduce your reliance on energy produced by fossil fuels.

3. Save energy and money on heating 

Heating, ventilation and cooling (HVAC) systems are the largest source of energy use for commercial and industrial buildings.

Quick, low-cost actions include:

• putting your thermostat on a timer 
• sealing your windows for extra insulation
• installing smart meters to see and control how much energy you use

Find out more about how your simple changes to your HVAC system can increase efficiency and reduce costs.

4. Review your refrigeration system

Install fixed point refrigerant leak detection systems to minimise fugitive emissions. Use low global warming potential (GWP) refrigerants and passive cooling.

Find out more about how to improve process cooling and refrigeration.

5. Decide if you need an energy strategy

Walk around your buildings to see if energy is being used efficiently

• look at lighting, machinery, heating, refrigeration systems and ventilation
• identify wasteful energy use and maintenance issues
• check at different times of day and compare day and night time use
• monitor over a period of a week for accurate average figures
• make sure equipment is checked and cleaned regularly to ensure maximum efficiency

Depending on the size of your business, you might need to implement an energy management strategy. An energy manager will help you:

• measure and monitor energy use.
• target ways to use energy as efficiently as possible

Find out more about developing an energy strategy from the Carbon Trust.

6. Train your team

You can train your team to be aware of energy efficiency in the workplace. Simple actions such as turning off and unplugging devices when they’re not being used can make a difference.

You could assign your energy management programme to a particular job role or working group, depending on the size of your business. This helps make energy savings a business priority and ensures long-term action despite staff turnover.

Find a sustainability training course to help you train your team.

7. Switch employees’ travel habits

You could introduce a cycle-to-work initiative or encourage them to take public transport if you have employees. It also makes sense to offer work from home where possible.

Find out more about how to switch your employees’ modes of transport.

8. Manage your waste

Prevent waste from being taken to landfill sites where it takes longer to break down and causes more emissions. 

Follow the Waste Electrical and Electronic Equipment Directive (WEEE Directive) and reuse, recycle and dispose of outdated equipment and devices to prevent e-waste and associated emissions. 

Find out more about your waste-related obligations and how to manage your waste.

Take longer term action

1. Make energy efficiency improvements to your workplace

You can make longer-term savings on energy bills by:

• insulating your workplace and replacing old windows
• changing from gas-fired heating to a ground or air-source heat pump 
• implementing energy efficient heating, ventilation and cooling (HVAC) systems

Check planning permission guidelines before you go ahead with any structural changes to the property.

You can download a free copy of DESNZ’s sponsored BS ISO 50005 energy management standard via the British Standards Institute website.

The standard provides SMEs with a means to develop a practical, low cost-approach to energy management to reduce their energy consumption, energy bills and carbon footprint.

2. Transition to electric vehicles

Over a quarter of the UK’s carbon emissions are caused by transport. 

You can reduce emissions if you use a work vehicle by switching to electric vehicles. You would be exempt from road tax, congestion charges and parking fees in certain areas.

For easy overnight charging you could install EV chargers at your home or workplace.

Visit our page to find out more about installing chargepoints.

3. Install renewable energy 

You might consider installing renewable sources of energy if you are the legal owner of your property. 

You can install:

• solar panels 
• a wind turbine for electricity
• an air or ground-source heat pump

With on-site generation and storage, you could make significant long-term savings on energy bills.

4. Choose cloud computing and improve your systems

Cloud computing services consume considerable energy. Choose your cloud computing on the basis of their commitment to sustainability.

Take a close look at your operations to see if you can:

• design software in a way that minimises the energy needed to run it
• limit data movement
• improve idle efficiency

Make changes in your supply chain

To reduce indirect or ‘supply chain’ emissions you need to consider what happens before and after your business provides a service or makes a product.

1. Choose greener suppliers and products (upstream)

You can reduce your upstream emissions by:

• using sustainability-conscious suppliers who actively measure and disclose their emissions
• including energy efficiency in your procurement considerations
• buying products that take less energy to make, transport and operate
• helping your suppliers with their carbon reduction plans

You can ask your suppliers:

• about lower carbon alternatives for their products
• to sign up to the SME Climate Commitment

Tell your suppliers to visit how to become a ‘net-zero’ ready supplier to find out more about the steps they can take to implement an effective carbon reduction strategy.

2. Reduce impacts from the use and disposal of your products and services (downstream)

You can reduce your downstream emissions by:

• making products that take less energy to make, transport and operate
• reducing water consumption and waste disposal needs
• making investments in lower carbon financial products
• giving incentives for lower emission activities in leased assets or franchises

Track and share your progress

You will need to regularly monitor and report your emissions data against your established baseline.

As part of the SME Climate Commitment, the SME Reporting Tool helps small businesses create annual sustainability reports and track their reduction efforts.

You should make your report publicly available to show what your company is doing to meet its targets and the impact of your initiatives on your company’s emissions.

You can integrate reported data into annual business reports, your website, or directly distribute to customers and funders.

Find out more about how to track and share your progress.
