Tesco slashed its CO2 emissions by 13% last year
Tesco slashed its CO2 emissions by 13% in 2017 compared to its 2016 level, as the supermarket giant moves to become a completely carbon-neutral business by 2050.
The British supermarket said it had achieved the reductions by increasing its use of renewable power - now used 100% in the UK and 55% globally - as well as investing in energy efficiency.
In doing so, Teso says it has reduced its net carbon intensity per sq. ft. of retail and distribution floor space by 6% compared to the previous year.
These reductions mean that the supermarket is currently on track to reduce its emissions by 35% by 2020.
It also plans to source 65% of its power from renewables by 2020 and 100% by 2030.

“It is recognised that we need to work together across society to build a truly sustainable future and the business fully supports global efforts to build this future, including the UN Sustainable Development Goals and the Paris climate agreement,” said Lindsey Pownall, Tesco’s Corporate Responsibility Committee Chair.
“The new targets ensure that our supply chain and operations support (the agreement) to limit global temperature rises to 1.5 degrees Celsius this century, as well as our long-term ambition to become a zero-carbon business,” she added.
In the same report, Tesco also reported strong sales growth achieving GBP£51bn (US$69.1) in sales in the past year across its 6,800 worldwide stores.
Trafigura and Yara International explore clean ammonia usage
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.
