About carbon offsetting

What is carbon offsetting?

Carbon offsetting offers a convenient and cost-effective way to reduce your carbon footprint. A carbon offset represents a reduction in greenhouse gas emissions that can be used to compensate for emissions made somewhere else.

How it works?
All liquid fuels release greenhouse gases (including CO₂ and NOx) into the atmosphere as part of the combustion process. CO equivalent (CO₂E) is a metric used to convert the net impact of all these gases into an equivalent amount of carbon dioxide with the same global warming potential. This helps to measure the impact of fuel use. All liquid fuel types have a CO₂E conversion factor.

How can I buy carbon offsets?

Where emissions can’t be avoided, you can purchase carbon offsets from Watson Fuels. Through our sustainability experts at World Kinect Energy Services, we offer two simple ways to reduce the net carbon impact of your business through carbon offsetting, and help you take your next step towards net zero.

Switching to offset fuel

Carbon Offset Fuel

When you buy carbon offset fuel from Watson Fuels, you’ll pay slightly more per litre of fuel, with a proportion of the price you pay going directly towards projects that compensate for the carbon impact of the fuel you’re using.

Simply ask our sales advisors to switch to offset fuel when you place your next fuel or heating oil order. By choosing to purchase Carbon Offset Fuel, you’ll be lowering your carbon footprint by directly contributing to the global carbon projects we’re partnering with, and the UN SDGs they are supporting.

To place your order for carbon offset fuel, please call your local office. Or, for further information, click below to send us an enquiry.


Offsetting your annual fuel emissions

Standalone carbon offset

We can also offer customers the option to purchase carbon offsets as a single standalone transaction independent of any individual fuel and energy purchase. This option is typically popular with businesses seeking to offset all their annual fuel emissions through a single purchase, or those wishing to go beyond offsetting the CO2e their fuel produces. By purchasing carbon offsets, you could cover all of your unavoidable business emissions, including scope 1 (direct) such as fuel use and scope 3 (indirect) like those created in your supply chain.

Purchase from a range of internationally verified projects, or work with our sustainability experts to create a tailored carbon offset solution to meet your business needs. With our global portfolio, you can also select which project type and location your offsets go towards, enabling you to align them with your business and stakeholder values. With each purchase, you will receive a certificate as evidence of how you have compensated for your emissions, so you can promote your efforts to your customers and engage your stakeholders.

Beyond carbon offsetting

While not a complete solution for managing your company’s entire carbon footprint, carbon offsets are an effective bridging mechanism that can be used to compensate for residual and direct carbon emissions.

But we can also help you go further. In partnership with our colleagues at World Kinect Energy Services, our sustainability experts can look beyond carbon offsetting to advise you on the most impactful, measurable and practical solutions to help your business reach its sustainability targets. Using our global expertise and local insights, we can help you make significant progress on your journey to net zero, no matter where you are right now.

Our projects

We only source carbon offsets from verified international projects

The carbon offsets that we purchase come only from projects that have been independently-verified against international standards. These standards provide a methodology, and an independent verification process and registry process that ensures emission reductions are real, additional, permanent, and unique.

Our offsets are sourced by our expert sustainability colleagues at World Kinect Energy Services, and meet one or more of the below standards and certifications:


verified carbon standards logo           gold standard logo                   

We’re currently sourcing Carbon Offsets from carefully selected renewable energy projects across India.

Where our offsets come from?
The offsets we source are procured from a range of solar and wind projects across India.

Which standards do these offsets meet?
As a minimum, these projects meet Gold Standard or Verified Carbon Standard (VCS).

What vintage do our carbon offsets represent?
Our offsets represent reductions happening in the last five years.

Which UN Sustainable Development goals do these projects support?
These projects support:
Goal 7 - Ensure access to affordable, reliable, sustainable and modern energy for all
Goal 13 - Take action to combat climate change and its impacts.




Frequently Asked Questions

Does offsetting only compensate for CO₂? What about my other emissions?

Carbon offsets are calculated by using the CO₂ equivalent (CO₂e) conversion factor for a given fuel type and quantity. CO₂e is a metric that converts the overall impact of all greenhouse gases (which includes CO₂, and NOx) into an equivalent amount of carbon dioxide with the same global warming potential. All liquid fuel grades have a CO₂e conversion factor.  So, while offsets are measured and calculated in carbon dioxide terms, the carbon offsets calculation does include the global warming impact of all greenhouse gases associated with the fuel. You can try our carbon calculator to see how this works.

But when you buy carbon offset fuel from Watson Fuels, we help take care of this detail for you. A proportion of the price you pay for each carbon offset fuel purchase goes towards projects that compensation for the overall carbon impact of the fuel you use and quantity you purchase.

What is Net Zero?

In 2019, the UK became the first major economy to pass laws committing it to bring all Greenhouse Gas (GHG) emissions to Net Zero by 2050. Net Zero effectively means that the sum of GHGs put into the atmosphere minus those removed equals zero.

The terms ‘Carbon Neutral’ and ‘Net Zero’ are often used interchangeably , and typically mean the same thing. However, Net Zero is different from Gross Zero, which means eliminating or preventing all GHG emissions in the first place. While this is clearly the ultimate goal – all major economies and organisations are now, or soon will be, taking steps to reduce emissions and cut carbon – Gross Zero is not yet a realistic target across all sectors and all applications.

Instead, Net Zero allows for unavoidable emissions – such as those from transport and heating applications, for which zero-carbon alternatives may not yet be viable – to be offset through carbon offsetting, or captured through carbon capture and storage (CCS) technologies.

Do I have to commit to a specific volume? Is there a minimum order quantity?

With Carbon Offset Fuel from Watson Fuels, you can choose to offset individual fuel orders, meaning you can offset 500 litres to 36,000 litres each time you place an order. The only one caveat: you can’t offset a proportion of an individual fuel order, meaning you must either select to buy Offset Fuel (and therefore offset all of that fuel order) or not.

I want to offset a larger quantity in one go. How can I do this?

For customers looking to source offsets for a larger fuel consumption in one go (e.g. “I want to offset last year’s fuel volumes”), we can also help. For this route, our colleagues at World Kinect Energy Services can help provide a consultative approach, helping you source the most suitable projects to match your business’ goals.

Can I choose offsets from a specific project?

For our Carbon Offset Fuel products, our expert team at World Kinect Energy Services take care of sourcing, and procure offsets from a variety of verified worldwide offset projects. You won’t be able to select your funds to go to a specific offset project, but rather you’ll be contributing to one of a number of projects within our carbon offset project portfolio. Bundling projects in this way allows us to maintain our competitive price point, as well as ensuring that we’re contributing only to global carbon offset projects that meet the strictest international standards and which drive positive global change.

Will I be buying a different fuel?

No. If you select Carbon Offset Fuel, the fuel grade itself is completely unchanged – you’ll simply pay a small premium to compensate for the carbon impact of the fuel. Watson Fuels can offer Carbon Offset Fuel products to cover all grades of liquid fuel we sell and deliver. That means our domestic customers can select, for example, Carbon Offset Premium Kerosene to be able to continue to receive our higher-grade heating oil, while also offsetting the carbon footprint.

I’m a domestic Monthly Payment Scheme customer. Do I need to change my payment amount if I want to switch to Carbon Offset Heating Oil?

No. As Carbon Offset Fuel requires you to pay only a small fraction more than your regular Premium Kerosene or regular burning oil, we typically do not need to amend your Direct Debit payment. You’ll simply need to order Carbon Offset Fuel when placing your order.

Am I buying a tree?

Not exactly. By choosing Carbon Offset Fuel, a proportion of the price you pay is contributing to a variety of projects that will offset the carbon dioxide equivalent of your fuel order. While our approved projects do include forestry initiatives, they also include renewable energy projects (such as wind and solar) from across the world. So, by carbon offsetting you’re not specifically planting a tree, but you are offsetting equivalent to the carbon impact of your fuel usage.

Why are the carbon projects you source from not in the UK?

As an international organisation, our colleagues at World Kinect Energy Services help us source offsets from a variety of projects around the globe. Crucially, we only source from projects that meet the strictest international standards, and which contribute to the UN Sustainable Development Goals we support. While that may eventually include us sourcing from UK projects, as the UK is a relatively small country the number of available projects is limited and can therefore be more expensive.

How do carbon offsets help us achieve Net Zero? Wouldn’t it be better to actually reduce emissions rather than certificate them?

We always recommend starting by reducing fuel usage where possible, through efficiency initiatives and projects. We’ve been doing this ourselves as part of our own carbon reduction plan. But beyond this, for many homes, farms and businesses, there is often no single solution to getting to Net Zero emissions. Lower and zero-carbon fuel options and alternative fuel technologies do exist, but they are often prohibitively expensive or difficult to source. Carbon offsets are recognised as a legitimate route to bridge the gap, and an economical interim measure while other innovations are developed for the medium term.
