If you've got a question, the chances are we've been asked it before. These are the most popular questions we get...

What is a carbon credit?

A carbon credit is the name given for a unit of one ton of carbon dioxide equivalent (CO2e). Specifically, in this case, carbon dioxide that has been reduced, or sequestrated via a project.

Carbon credits fulfill their role when they are retired, this certificated action means they then become Offsets. The retirement of the carbon credit is the last stage of the lifecycle and their function has been fulfilled.

When we retire carbon credits to balance the carbon emissions for your organisation or project, we record your name and the specific project the carbon credits came from. In addition, we record the credits identification serial number and the certificate for each. We do this to ensure that the retired carbon credits don’t go back into the system and that your carbon has been certified as such. This is why we only retire Verified Carbon Credits with high additionality scores for you.

Carbon credits whether retired or circulated are registered, this work is completed by independent registries. These independent organisations are transparent in their work so that the relating data is publicly available. This is a vital back stop to the certified process.

The projects we work with meet the highest standard and stringent criteria in order to attain accreditation. Additionality is the most important aspect that we work to, this means that the projects that our credits are drawn from are entitled to generate carbon offset credits by demonstrating clearly that they couldn’t have been delivered without the vital investment created from the sale of those credits.

What does carbon offset mean?

Carbon Offset, reduction or Offset carbon footprint. Defines a state where an organisation, event or action is net zero in terms of CO2e emissions. This is achieved by offset through the Verified Carbon Credit Registry, VERRA, with Verified Carbon Credits.

In other words, you invest in carbon credits which fund carbon-cutting schemes and technologies across the world to help others reduce their carbon emissions, effectively balancing out our own.

What does carbon neutral mean?

Carbon Neutral or Carbon neutrality, or net zero carbon footprint. Defines a state where an organisation, event or action is net zero in terms of CO2e emissions. This is achieved by creating a balance between the amount of CO2e emissions and the amount combined via offset, sequestrated and carbon credits.

What Standard do you offer?

Carbon Neutral International Standard

Carbon Neutral International Standard is particularly useful if you have very precise carbon reduction goals. Our team can guide you through this process and help you to neutralise the Carbon footprint of your organisation or event with up to 80% funded support on acceptance.

If you don’t already know your footprint, then we will help you to calculate it. This can have significant economic benefit, not only with a potential reduced requirement for carbon credits, significantly more cost effective, the savings and financial efficiencies can be employed in additional and creative ways.

​What does “awarded Carbon Neutral International Standard” means?

This means that your organisation has established a systematic and methodical approach to a low carbon economy, that you have implemented a strategy and have become engaged, and more importantly that you are experiencing rewards and have become proactive.

How does One Carbon World choose which Carbon Offset projects to support?

Our independent panel choose from programmes that as a prerequisite have a scoring factor of 6 or above in economic impact and supporting the local community, and a scoring factor of 6 or above in local bio-diversity enhancement. However, a score of 6 is a minimum benchmark for a project to be considered; many projects score 8,9 or 10. The social impact of the programmes we carefully select includes improved health and educational facilities. Further checks are carried out on understanding support requirements and future plans.

Why should organisations support Verified Carbon Credit projects and programmes?

As long as fossil fuels are burned, forests are currently the only viable and scalable answer to re-capture carbon or CO2 from our atmosphere. In fact, the Paris Agreement underscores the urgent need for carbon sinks like forests to meet the ambition to limit global temperature rise to ‘well below 2°C’.

Are carbon credits permission to pollute?

No. Carbon credits are an investment in emission reductions to drive the transition to a low-carbon economy. Even with clean energy gaining momentum, there is a tremendous gap to fill to meet the ‘well below 2°C’ target the Paris Agreement sets for limiting global temperature rise. Companies that set ‘Science Based Targets,’ that is, internal emission reduction targets in line with what science tells us to limit warming to 2°C’, and then go beyond by supporting projects that reduce global emissions, are demonstrating corporate best practice in terms of climate action. By choosing high additionality projects for their carbon credit purchases, they are also helping to bring sustainable development benefits – like access to energy and water, new jobs, and better health – to communities around the world.

What are Social and Biodiversity benefits?

All our Carbon Credits are produced by Verified Carbon Credit projects that are carefully selected and assessed by us to ensure that they are ‘holistic’.

The projects we have selected not only reduce carbon but also provide a high level of additional benefits that encompass bio-diversity, social enhancement and micro and macro economic development.

Bio-diversity is defined as the variety of living organisms in all terrestrial or

aquatic ecosystems. Our Verified Carbon Credit projects are part of the ecological complex. The projects have been developed to ensure they have a positive impact on local ecosystems.

The social and economic benefits that are created in local communities include

Sustainable local employment and economic empowerment,

Local education funding,

Improved local health and welfare facilities.

By participating in offset with Carbon Credits you invest in local communities.

Why carbon neutral?

According to the United Nations, "to avoid the worst effects of climate change, science tells us that we must limit global temperature rise to less than 2 degrees Celsius, which is also the central goal of the Paris Agreement. To achieve this objective, relying solely on governmental action will not be sufficient." Verified Carbon Offset programs are vital catalysts to achieve real and meaningful change and low carbon economies. Reducing greenhouse gas emissions can provide a variety of environmental, social and economic benefits.

How does OCW measures an organisation's carbon footprint?

We measure the GHG emissions through the application of documented and approved GHG emissions conversion factors. These factors are calculated ratios that relate GHG emissions to a proxy measure of activity at an emissions source.
The activity data or amount of ‘resources’ used are multiplied by the relevant emissions factors to calculate total Greenhouse Gas equivalent (CO2e) emissions.
GHG emissions = activity data x emission conversion factor
There are seven main GHGs that contribute to climate change, as covered by the Kyoto Protocol: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6) and nitrogen trifluoride (NF3). Different activities emit different gases and an organisation should report on the Kyoto Protocol GHG gases produced by its activities. CO2e is the universal unit of measurement to indicate the global warming potential (GWP) of GHGs, expressed in terms of the GWP of one unit of CO2.
The GWPs used in the calculation of CO2e are based on the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) over a 100-year period (this is a requirement for inventory/national reporting purposes).
All conversion factors used in the measurement of our GHG emissions are in units of kilograms of carbon dioxide equivalent (kg CO2e).
This ensures the reporting requirements of the Green House Gas (GHG) Protocol Corporate Standard and compatibility with international standards ISO 14064 and
PAS 2060.

When was One Carbon World created and what is OCW's mission?

One Carbon World a not for profit organisation established in 2019, whose
core business is to promote voluntary climate action now, through measuring,
reducing, and off-setting the Carbon Footprint of organisations and events.
The company mission is to retire 10 million carbon credits over the next four years.
Founded by a business entrepreneur and an experienced environmental scientist,
OCW is built on long term experience and professional knowledge of business,
energy, and science sectors. OCW combines this knowledge and experience to
provide its clients with the know-how and support to enable them to realise their aim
of becoming carbon neutral, or net zero carbon, for their activities.

What did One Carbon World achieved so far?

OCW has already worked with major international corporations and events,
as well as local and regional authorities, schools, farmers, manufacturers, fashion
retail and service and health care providers.
We wanted to create an inclusive support programme that also specifically targeted
underrepresented sectors and countries.
In 12 months One Carbon World have supported 10% of all participants with the UN
Climate Neutral Now Initiative.
In 12 months 40 companies are now carbon neutral and have net zero emissions
through the OCW grant, and we also support companies in 24 countries and
growing. This demonstrates the scalability of the OCW approach.
We have received confirmation of 40 further international companies who have
committed to becoming carbon neutral.
In the last 12 months we have we have created a robust and diverse team of experts
and academics around the world and we report on global organisation footprints
within an agreed timeframe of 60 days from receiving emissions data.
We support 5 key areas, small to medium businesses, large organisations, events,
education & government, and underrepresented sectors and countries (the latter is a
project we are working closely with the UN Climate Team).
In the last 12 months we have added world first representation to the UNCNN from 1
country and 3 sectors (Animal Welfare, Cycling café, Male Grooming).
In the last 12 months we have we have mapped carbon emissions that effect
300,000 staff, millions of customers and thousands of students.
In the last 12 months we have we have offset more than 250,000 journeys that
directly support emission reduction projects.
Several businesses are now adopting our business transformation strategies and
even includes commitment to zero business travel for staff.
