Reducing Our Carbon Footprint at Mosaic's Operations

Your carbon footprint is defined as the greenhouse gases you emit annually. It’s not just the fuel you burn to heat your home or drive your car. It’s also the products and services you buy, the electricity you use, and emissions from power plants providing that electricity.

As a publicly traded company, Mosaic has a responsibility to minimize its own carbon footprint—and we are making good progress. As one of the first crop nutrition companies to announce a commitment to reducing greenhouse gas (GHG) emissions, Mosaic pledged to decrease North American Phosphates Business Unit GHG emissions by 10 percent and emissions intensity by 5 percent, from 2005 levels, by 2015.

We’ve kept our promise, and have already outperformed that goal. According to Mosaic’s 2013 Sustainability Report, the Phosphates Business Unit reduced annual absolute Scope 1 and 2 greenhouse gas emissions by 21 percent (excluding ammonia), and decreased emissions intensity by more than 15 percent since 2005.

Taking Action

How are we making this progress? The results span our operations.

  • Natural Gas Truck Fleet: In 2013, Mosaic oversaw the conversion to a natural gas-powered truck fleet for raw materials and finished products in our Central Florida operations. The 50 trucks, operated by transportation company Dillon Transport, have increased capacity and are powered by clean-burning compressed natural gas. Benefits include significantly lower emissions of particulates and nitrogen oxides (up to 50 percent lower) and GHGs (potentially up to 25 percent lower). Based on forecasted shipping volumes, we estimate this conversion will save at least $1 million annually.
  • Cogeneration: Mosaic produced approximately 6.24 million gigajoules of electricity through cogeneration, the process of converting waste heat to energy—resulting in enough energy to satisfy 44 percent of companywide electrical demand. By producing and using its own clean energy, Mosaic avoided approximately 1 million tonnes of carbon equivalent emissions, which is comparable to taking an estimated 205,000 cars off the road.
  • Renewable Energy: Mosaic’s three-pronged approach of energy management through cogeneration, conservation and greater efficiency aims to lead the industry in reducing the energy we use and maximizing the clean energy we generate. We are committed to evaluating alternative energy sources to satisfy Mosaic’s energy requirements. Since 2008, we have improved our total energy per tonne of finished product by over 10 percent.
  • N-ViroMotive Locomotive: Used at our South Fort Meade mine, this locomotive requires approximately 57 percent less fuel and emits approximately 80 percent fewer GHGs than single-engine diesel locomotives.
  • Belle Plaine Water-Sharing: Through an agreement with an industrial partner in Saskatchewan, Mosaic’s Belle Plaine facility sends water to be used in a cooling process at a nearby plant. The heated water returns to Mosaic’s facility to be used as part of the potash production process. This synergy allows Mosaic to reduce the amount of energy that would have otherwise been spent on heating the water while allowing the industrial partner to avoid cooling costs.
  • PhosPro Raw Materials Handling: Cross-functional teams at Mosaic and CSX focus on increasing efficiencies and reducing costs for both companies. Expected benefits include moving more finished products upstream by rail instead of truck, resulting in improved fuel efficiency and lower GHG emissions.
  • RightShip: Using this vetting service allows Mosaic’s Supply Chain team to select vessels that meet safety and environmental criteria, including energy efficiency and GHG emissions performance. By chartering the most fuel-efficient vessels available, we are reducing the environmental impact associated with transportation of materials.
