Measuring your farm’s carbon footprint

To understand the overall impact of fertilisers on the environment, we need to conduct a life-cycle analysis, which measures emission and absorption rates of greenhouse gasses at every stage of a fertiliser’s ‘life’. This will help determine the carbon footprint and show how it can be minimized.

In production, transportation and use, fertiliser products generate greenhouse gas emissions, including carbon dioxide (CO2) and nitrous oxide (N2O).

Carbon life cycle of nitrogen fertiliser


4 ways that you can minimize carbon emissions

  • Select ammonium nitrate produced by a manufacturer utilizing the cleanest and most efficient production technologies available
  • Take action to ensure balanced nutrition by using precision tools for optimum N rate application
  • Optimize fertilization as this can increase C02 uptake and crop growth
  • Reduce the need for new land cultivation by increasing yield with highly efficient nitrogen fertilizers

 Yara has reduced carbon footprint in production of fertilizer by 40%


Yara is working to reduce its carbon footprint

  • Yara has reduced the carbon footprint of its nitrate fertiliser production by up to 40%. Enhancing N efficiency during fertiliser use could reduce this even further
  • Yara has developed advanced technologies that are used during fertiliser production to reduce N20 emissions by up to 90%. We have shared this technology with the rest of the industry, and it is now part of the ‘Best Available Techniques’ (BAT) for fertiliser production as defined by the European Union
  • Average emissions from the application of AN fertiliser are 5.1 kg CO2-eqv per kg applied N [7]. This is due to N2O losses caused by denitrification and volatilization in the soil. Since N2O has a strong impact on the environment, N2O losses are an important consideration.

90% less N2O from production

The use of catalyst technology developed by Yara for use in fertiliser production can reduce N2O emissions by as much as 90%. This technology has since been shared with the rest of the industry. Today, the technology forms part of the 'Best Available Techniques' (BAT) for fertiliser production as defined by the European Union.



Yara's commitment to reduce climate change

Can you responsibly feed the world and reduce CO2 emissions?

Without mineral fertiliser, the world could only feed 40% of its population. But to make mineral fertiliser you need to rely on fossil fuels to generate the required production energy, resulting in CO2 emissions.

That’s why Yara is working on alternatives like Green Ammonia. A breakthrough that will provide the level of fertiliser production required to responsibly feed the world, while at the same time reduce CO2 emissions.

With growing investments in wind, solar and hydrogen, Yara is currently running production pilots using renewable CO2-free energy sources to produce Green Ammonia. Yara is targeting to make Green Ammonia a proven production method within the next few years. Another advantage of Green Ammonia is that it can also be used to store and transport carbon-free energy for power plants, industrial furnaces and as fuel for mobility, thus providing a more sustainable resource for use by manufacturing, energy and transportation industries.

Green Ammonia provides us with the prospect of a cleaner future for energy-intensive production and storage methods. Effectively reducing our dependence on fossil fuels while moving towards a low-carbon society.
