Negative emissions for a positive future
A new industry is emerging around the active removal of carbon dioxide (CO₂) from the atmosphere.
Climate action
Negative emissions make an indispensable contribution to achieving our climate targets. They help to stabilise CO₂ levels in the atmosphere, offset residual emissions that are difficult to avoid and, in the long term, remove more CO₂ than we emit.
Apply for a Think Negative session at COP31
The Think Negative coalition — around 150 companies initiated by the Negative Emissions Platform — hosts a limited number of programming slots at COP31 in Antalya, 9–20 November 2026. Slots are allocated based on alignment with the selection criteria.
Sponsorship Opportunities
Give your organisation a visible base at COP, connect with policymakers, buyers, investors and the wider carbon removal community, and showcase your work through the Think Negative Pavilion.
Every sponsorship directly supports the coalition’s shared presence virtually and in the Blue Zone.
CDR methods
Enhanced rock weathering
This method accelerates the natural process of mineral weathering in order to bind CO₂.

Bioenergy with CO₂ capture
Generating electricity/heat or biomethane from biomass, capturing and storing CO₂ or using it in long-lasting products.

Biochar carbon removal
Converting biomass or other biogenic material into a stable form of carbon that is used to improve soils or in long-lasting products such as asphalt or cement.

Improved forest management
Planting new forests and restoring existing ones to capture CO₂ through photosynthesis.

Soil carbon sequestration
This method improves carbon storage in the soil through practices such as direct seeding, cover cropping and organic materials.

Blue carbon management
Conserving and restoring coastal/marine ecosystems such as mangroves, seagrass and tidal marshes.

Ocean fertilisation
Adding nutrients such as iron or phosphorus to oceans to promote phytoplankton growth (which absorbs CO₂ through photosynthesis).

Alkalisation of oceans and rivers
This method can increase the ocean’s capacity to absorb and store CO₂ by adding alkaline minerals to seawater.
