Delivering the world's first premium value green fertiliser

The need for ATOME's green fertiliser

ATOME is making a major impact on the existing 2.6 billion ton/year carbon emitting industry

problem

Virtually all nitrogen fertiliser (98%) is made using fossil fuels

Fertiliser feeds approximately half of the world's population which grows by 1 billion people every 15 years

The production and use of fertilisers emits 2.6 billion tons of CO2 emissions per year (5% of global GHG emissions) - more than global aviation and shipping sectors combined

solution

ATOME's green fertiliser significantly reduces production emissions whilst maintaining crop yield

ATOME's supply of up to 270,000 tons/year of affordable

sustainable fertiliser from Phase 1 Villeta will enhance regional food security and displace up to 15 million tons/CO2eq over its lifetime, equivalent to…

ATOME's solution for today's market

Delivering a green solution for today's grey market, eliminating dirty emissions

UK MARKET

• UK significantly relies on imports, consuming 1.4 MT/year of fossil-fuelbased fertiliser
• UK energy market makes it unviable to produce fertiliser as major production sites have been mothballed
• Energy crisis and Ukraine have materially impacted UK's fertiliser sector, increasing prices and driving volatility
• As a result, UK farmers pay a premium for imported nitrogen fertilisers

INTERNATIONAL AND LATAM MARKET

• Mercosur is the world's largest import fertiliser market - Brazil, Argentina and Paraguay imports over 30MT/year of fertiliser (2021)
• Europe CAN demand forecast to grow to approx. 14Mt by 2045

THE MOVE TO GREEN

CBAM	Fertiliser will be a CBAM product (carbon border adjustment mechanism) from 2026, with the UK
from 2027, meaning imported fertilisers will be taxed according to their carbon intensity
ETS	Under the UK Emissions Trading Scheme, the UK aims to lower the overall emission cap and increase
its annual rate of emission reduction, applying pressure on consumers to decarbonise

OUR GREEN SOLUTION

• ATOME is the UK's only large-scale developer of green fertiliser
• Flagship project located in the world's largest import fertiliser market
• Able to supply Latin America and the UK
• Low-costfertiliser, reducing reliance on costly imports of dirty fertiliser
• ATOME's zero-carbon fertiliser will not be taxed on import to the UK
• Could command a green premium whilst retaining application benefits for UK farmers

Pressure Chain and Policy

ATOME provides relief for increasing pressures of sustainability across the entire food value chain

Consumer flow

Stakeholders	Food Brands

Downstream

Agriculture Traders

Pressure to decarbonise

Farmers

Upstream

Governments, NGOs and investors

are increasing pressure on corporates to reduce reported emissions*

Firm measures such as CBAM, ETS, SBTi in place

Mainstream banks adopting emissions targets and fossil fuel exclusion policies on lending

*under SBTi and Partnership for Carbon Accounting Financials (PCAF) standards"

Major global food producers (who contribute nearly one-thirdof global emissions) are under pressure to decarbonise their direct, indirect and

value chain emissions

Net zero emissions by 2039

Net zero GHG emissions by 2050

As the use of fertilisers in food production contributes to 5% of global emissions, agriculture businesses are looking to reduce their

own supply chains and to source the cleanest produce on the market

Reduce emissions by 30% per ton of product sold by 2030

25% reduction of Scope

3 GHG footprint by 2035

To continue as preferred suppliers of agricultural produce, farmers are now required to adapt and adopt

sustainable practices, including the

use of green fertilisers
