(gentle music) - At Boomitra, we work with farmers and ranchers all around the world to increase soil carbon levels by implementing improved agricultural practices.

- [Narrator] Across the world, land use intensification and climate change have degraded the Earth's soil.

But Aadith Moorthy and the team at Boomitra are working with farmers to improve the health of their soil.

They do this by supporting farmers and ranchers to adopt regenerative practices, which has an additional benefit of helping to capture carbon from the air.

Boomitra then use satellite technology to monitor and verify the volume of carbon sequestered in the soil and have the revenue from carbon credits back to the farmers.

Now working with 150,000 farmers, Boomitra have a target to store one gigaton carbon dioxide in the soil by 2030.

- [Aadith] At Boomitra, we enable farmers all around the world to be a key part of the solution.

(tranquil music) - Aquacycl is a company that provides technology and services for distributed wastewater treatments of agriculture, industry, and sanitary waste.

- Treating wastewater before it reenters rivers and oceans is vital for protecting people and the planet.

But wastewater treatment can be an energy-intensive process.

In the US, Orianna Bretschger and the team at Aquacycl use naturally existing bacteria to treat wastewater and generate electricity in the process.

Aquacycl are already working with multinational companies and claim to cut the carbon emissions of their wastewater treatment by up to 50%.

They aim to expand to new continents in the next few years.

- [Orianna] The implications of our technology out in the world is to ultimately mitigate greenhouse gas emissions and climate change.

(water bubbling) - Sea Forest is an environmental technology company focused on the mitigation of livestock methane emissions, using a seaweed native to Australia and New Zealand called as Asparagopsis.

- [Narrator] The raising of livestock emits large amounts of methane, one of the biggest contributors to greenhouse gas emissions in our atmosphere.

Environmentalist Sam Elsom and the team at Sea Forest have developed ways to cultivate the seaweed on the large scale.

And from this, they make their SeaFeed supplement, which, when fed to livestock, has the potential to reduce their methane emissions by up to 98%.

Sea Forest say they've already produced more than 1 million doses of SeaFeed and claim the capacity to reach 15% of Australia's cattle.

- We have a solution that can create a huge impact today.
