COP31 Turkiye: Our Reef Credit Program Case Study

From the 9th to the 20th of November 2026, COP31 will bring together delegates from many different countries in the hopes of strengthening global climate commitments and accelerating action towards achieving a more sustainable future.

At Cequest we can create a pathway towards this future through unlocking the value of nature-based solutions.

Building practical pathways between nature and business.

Nitrogen fertiliser is commonly used on farms however a portion of the nitrogen is not absorbed by plants and instead can be transported into waterbodies as pollution, impacting plants and wildlife. Sugarcane contributes to 42% of the dissolved inorganic nitrogen transported to the great barrier reef, especially in the Mackay Whitsunday region.

Our registered sugarcane farm projects are spread across the Mackay-Whitsunday and Great Barrier Reef catchment area. These projects aim to increase the quality of water flowing into the Great Barrier reef through nitrogen use efficiency. We do this by enhancing microbial nitrogen retention, improving soil health, implementing carbon building practices and applying algae-based biostimulants.

These projects generate ENVOMARK Reef Credits, certified by Eco-Markets Australia. Each credits represents 1kg verified dissolved DIN. Reef credits generated by our projects can be bought by those who would like to invest in our work, providing the farmers implementing our projects with a new revenue stream.

Here’s how our process works:

1. First farmers are assessed for eligibility and then we improve fertilizer efficiency by applying our biostimulant blends which reduce nitrogen needs

2. Secondly monitoring is implemented to assess changes in farming practices at the target site and independent assessment is conducted for reduced dissolved inorganic nitrogen (DIN) runoff.

3. When DIN reductions are verified, they become ENVOMARK Reef Credits

4. Buyers make offtake agreements whereby they meet ESG, supply chain and water quality agreements.

In just 4 months we have reduced dissolved inorganic nitrogen by 26-60% on target farms covering 710 hectares. This corresponds to 33.7 tons of applied nitrogen reduced. Our services mean that farmers have to pay less for fertiliser whilst also maintaining their yield and protecting them from fertilizer price shocks. Our buyers are able to have a direct impact on farming, support climate and sustainability goals and supply chain resilience.

We aim to manage another 15,000ha in Queensland by 2028 as well as more land across Australia and international maturing markets.

We are also excited to announce that our Reef Credit program will be showcased at COP 31! The team from Carbon & Clean Energy Solutions will be hosting a discussion on our Reef Credit case study, exploring how environmental markets can support measurable improvements in water quality and ecosystem health.
