The US retail firm, Walmart, has announced that since launching its Project Gigaton initiative in April 2017, its suppliers have saved more than 20mn metric tons of greenhouse gas emissions in global value chains.

The ultimately initiative aims to reduce emissions from the company’s global value chain by 1 gigaton by 2030.

Project Gigaton has recently expanded in China and the UK, raising its supplier participation to over 400, spanning across 30 countries.

“In its first year, Project Gigaton has helped to inspire action that has led to the avoidance of millions of metric tons of greenhouse gas emissions and has expanded into an international campaign that includes the participation of several hundred suppliers,” said Senior Vice President and Chief Sustainability Officer for Walmart, Kathleen McLaughlin.

“The early success of Project Gigaton parallels ongoing progress in our operational efforts that seek to double our U.S. renewable energy use and expand our customer electric vehicle charging hubs to retail outlets across more than 30 states.”

Walmart discussed its tactics to reduce emissions, highlighting goals to expand commitments with wind and solar power, and electric vehicles.

“This annual milestone marks a pivot point for Walmart and 400 of its suppliers to share solutions and lessons learned,” stated Carter Roberts, President and CEO of the World Wildlife Fund (WWF).

“The next step is to deepen commitments that unlock the potential of this platform. We need collaborative initiatives like Project Gigaton and We Are Still In.”

“With sufficient goals and results they can help define our country’s ability to build a sustainable future.”

“And they also shape the world’s understanding of our commitment to solving climate change.”

Trafigura and Yara International explore clean ammonia usage

Commodity trading company Trafigura and Yara International sign MoU to explore developing ammonia as a clean fuel in shipping

Independent commodity trading company Trafigura and Yara International have signed an MoU to explore developing ammonia as a clean fuel in shipping and ammonia fuel infrastructure.

Reducing shipping emissions is a vital component of the fight against global climate change, yet Greenhouse Gas emissions from the global maritime sector are increasing - and at odds with the IMO's strategy to cut absolute emissions by at least 50% by 2050. 

How more than 70,000 ships can decrease their reliance on carbon-based sources is one of transport's most pressing decarbonisation challenges.

Yara and Trafigura intend to collaborate on initiatives that will establish themselves in the clean ammonia value chain. Under the MoU announced today, Trafigura and Yara intend to work together in the following areas:

  • The supply of clean ammonia by Yara to Trafigura Group companies
  • Exploration of joint R&D initiatives for clean ammonia application as a marine fuel
  • Development of new clean ammonia assets including marine fuel infrastructure and market opportunities

Magnus Krogh Ankarstrand, President of Yara Clean Ammonia, said the agreement is a good example of cross-industry collaboration to develop and promote zero-emission fuel in the form of clean ammonia for the shipping industry. "Building clean ammonia value chains is critical to facilitate the transition to zero emission fuels by enabling the hydrogen economy – not least within trade and distribution where both Yara and Trafigura have leading capabilities. Demand and supply of clean ammonia need to be developed in tandem," he said.  

There is a growing consensus that hydrogen-based fuels will ultimately be the shipping fuels of the future, but clear and comprehensive regulation is essential, according to Jose Maria Larocca, Executive Director and Co-Head of Oil Trading for Trafigura.

Ammonia has a number of properties that require "further investigation," according to Wartsila. "It ignites and burns poorly compared to other fuels and is toxic and corrosive, making safe handling and storage important. Burning ammonia could also lead to higher NOx emissions unless controlled either by aftertreatment or by optimising the combustion process," it notes.

Trafigura has co-sponsored the R&D of MAN Energy Solutions’ ammonia-fuelled engine for maritime vessels, has performed in-depth studies of transport fuels with reduced greenhouse gas emissions, and has published a white paper on the need for a global carbon levy for shipping fuels to be introduced by International Maritime Organization.

Oslo-based Yara produces roughly 8.5 million tonnes of ammonia annually and employs a fleet of 11 ammonia carriers, including 5 fully owned ships, and owns 18 marine ammonia terminals with 580 kt of storage capacity – enabling it to produce and deliver ammonia across the globe.

It recently established a new clean ammonia unit to capture growth opportunities in emission-free fuel for shipping and power, carbon-free fertilizer and ammonia for industrial applications.
