You can make a measurable impact on the climate crisis and defund war, with the power of nature

Try our carbon footprint calculator

First, let’s see how much CO2 you generate. This is your carbon footprint.

Now offset your carbon footprint

Our offset products and services are science-based and data-driven, with impacts measured. Our platform connects you with licensed growers in Ireland and around the world who grow industrial hemp. We measure all our partner crops’ inputs and outputs. Then we lock the carbon away, permanently and safely, in hempcrete homes and buildings.

Fabulous, verified, fully considered, and 100% sequestered Hempoffset carbon credit products are now available, for businesses and consumers worldwide! Everything we do is science-based, data-driven and impacts are measured. When you purchase any of our Carbon Credit products, 40% of your investment goes to the grower who captures the carbon, 40% goes to the hempcrete maker who sequesters the carbon, and 20% goes to fund our operations. Ideally, the grower and maker will be the same person or organisation, to minimise the transportation carbon footprint. In this case, they will receive 80% of your investment.

Outstanding! A truly carbon neutral business

If you’re a business owner and want to have a carbon neutral operation, quickly and easily, learn more about our business carbon service. Our products help enable carbon neutral data centres, in real time, across construction, operation and legacy.

So, you’ve had enough of funding war, murder, and destruction? There is a better way!

Our mission is to stop climate change – effectively and quickly – and we’re inviting you to rethink verified carbon credits

Hempoffset is the first true carbon capture and sequestration product that supports businesses and individuals with their efforts to go carbon neutral in near real-time. Our method: Industrial hemp, grown at scale with our carbon measurement and offset platform, supplying the best quality carbon credits in the world to Voluntary Carbon Markets.

Hempoffset carbon credits are unique:

  • Multiple, positive impacts are measured and made transparent. The quantity of CO2 we remove from the atmosphere is our key impact. Additional impacts in job creation, sustainable development, and behavioural change.
  • Additionality, removing CO2 in new projects.
  • Validated, Verified, and Certified by the Department of Agriculture, Ireland (Irish operations).
  • Fully considered: Only net gains are brought to market.
  • Permanently and safely sequestering CO2.
  • Used to produce hempcrete for carbon-zero private and commercial buildings.
  • Our carbon products and services are science-based and data-driven, with all impacts measured.
  • Transparent, end-to-end carbon credit registry to build trust.

Co-benefits of industrial hemp include helping pollinators thrive, bees and other insects; environmental justice by redistributing value; better for the environment with no need for herbicides or pesticides; and significant job creation.

Businesses and individuals use our platform to measure, reduce, and manage their carbon footprints. Offset the business, the project, or the activity by the metric tonne, with guaranteed, additional, permanent sequestration of the target carbon footprint.



Together, we’ll plant enough hemp to go carbon neutral fast, stop climate change, and defund war

Respect! Grow hemp with us

We want to grow a billion acres of hemp, all over the world. If you are already dedicated to growing hemp, or just want to try it as a rotation crop, get in touch. If you are new to hemp and want to learn how to grow it, get in touch. We need you. The planet needs you.

Industrious you! Make hemp products

When you need hemp crops for your products, we connect you with growers near you, in Ireland and around the world, who will meet your supply needs.

You can also sell your hemp and sustainable products in our store. Get in touch today…

Greentech can save us, we can’t leave it to politicians, quangos, and NGOs

We’ve started a movement that will easily enable the planting of enough hemp to stop climate change. Our target is to plant over one billion acres a year, on our new, sustainable, Greentech value platform. We know we need to build a carbon-neutral, and then a carbon-negative lifestyle worldwide, with equality, opportunity and respect for nature and each other at its heart. But we’re human, so we won’t do that until it’s too late. Hempoffset will buy us time, making it super-easy for anyone, or any business, to go carbon-neutral.

A billion acres of hemp

A billion acres (400 million hectares) of hemp is around 4% of habitable land and will remove up to 10 metric gigatons (a gigaton is 1 billion metric tons) of CO2 from the air each year, that’s about a quarter of the world’s annual emissions.

Isn’t 4% a lot of land?

Not really, especially when you consider that 40% of the planet’s arable land is currently used for dairy and livestock. Most of the hemp fibre we grow will be used to make hempcrete, an incredible construction material, and we’ll build sustainable homes for everyone on Earth who needs or wants one. We’re using one problem to solve another. Everything we do with our hemp carbon offset products and services is science-based and data-driven. Hempoffset is a win-win.

The science of hemp and carbon offset

There is a growing awareness that Nature-based Solutions (= NbS = plants) hold the key to solving the climate crisis. Why risk tampering with the atmosphere (will we ever learn?) or waiting for some new technology to be invented, when plants and trees are already working hard (along with the ocean) to pull the planet back from the brink? Trees are a good strategy, so let’s plant billions of them, everywhere possible. But, trees can take 30-40 years to make a net positive carbon impact and time is of the essence (Also: forest fires). That’s why hemp is the answer.

Hemp absorbs literally tons of CO2 when growing

Hemp is simply the most effective crop at removing CO2 from our air. One acre/0.4 ha of hemp can absorb up to 10 tons of CO2 from the atmosphere, pumping out the same amount of oxygen, and in a single year! Hemp grows real fast, with three crops a year achievable in hot climates. Hemp is also a great rotation crop, requires no pesticides and needs only half the water of most other crops.
