There has never been a more urgent need to reduce business Carbon emissions.

Carbon Calculators can tell you what your carbon emissions are, but our Carbon Reduction Assessments tell you what you can do to reduce and offset them. Many businesses self assess their carbon emissions, however this does not provide independent verification or support in carbon reduction planning. Tunley Engineering are able to provide your organisation with a quantified pathway to achieveNet-Zero Carbon.

If you’re looking for detailed carbon reduction guidance beyond ‘turning lights off when you’re not using them’, and if you’re committed to making a real, sustainable difference towards a Net Zero Carbon Future, then our Carbon Reduction Assessments are what your business needs. We’ve worked with businesses worldwide to help them assess their emissions and come up with a carbon reduction plan.

Find out More About our Carbon Assessments

Our team of PHD level scientists work with your business to go beyond crunching the numbers to provide you with clear and comprehensive detail about exactly what your Carbon Emissions are, and what you need to do to report on them against internationally recognised standards like DEFRA (Department for Environmental and Rural Affairs) and the GHG Protocol.

When we talk about a Carbon Assessment, we use “Carbon” to refer to all greenhouse gases. It is used as a collective term for any emission that contributes to global warming, so when we assess your business’s Greenhouse Gas Emissions (GHG’s) we can take into account all the contributing factors to your overall Carbon Emissions.

A Carbon Assessment can provide more value to a business than just proof that steps have been taken to review and reduce carbon and other emissions. With proof of having assessed and reduced and offset carbon usage verified by Tunley Engineering as a third party, your business can work towards B-Corp status, bid on government contracts and improve efficiency and cost within the business.


Years of Engineering Process Improvement experience has shown us you can only manage the carbon that you measure. Setting a baseline, using accurate calculations that are peer-reviewed by a team of experts, followed by accurate reporting, lets us help you identify areas of emissions, quantify the size of the problem, and set solution-focused targets and processes for carbon reduction.

Most Carbon reporting divides your Carbon Emissions into 3 Scopes

However, this simple categorisation of emissions doesn’t go beyond quantification and identifying what areas are responsible for them.

For any environmentally responsible organisation it is vital that their Carbon Reduction efforts start with measurement, but then immediately move onto undertaking the actionable next steps to deliver a reduction in carbon emissions. Our Carbon Reduction Assessment provides you with the roadmap to do this. We will guide you through the full process, drawing on experience.


Net Zero Carbon for your Business

Our carbon reduction solutions also include Carbon Offsetting, an action or activity that acts as a carbon sink, removing carbon from the atmosphere and allowing organisations to further contribute to achieving a Net Zero Carbon world, where the result of reducing carbon emissions and offsetting the remainder results in Net Zero Carbon emissions.

Our Carbon Reduction Assessment also presents you with a variety of compelling ways you can communicate your progress to your stakeholders, without unnecessary jargon.

In summary, our Carbon Reduction Assessment;


Measures the sum of all greenhouse gases emitted by the activities of an organisation.


Sets out realistic actions and goals for Carbon Reduction, including the overall resulting reduction in greenhouse gases these actions would deliver.


Provides clear, actionable steps to offset your existing carbon footprint.
