Environmental Impact Targets BY THE NUMBERS 2025 ESTIMATED REDUCTION TARGETS FROM 2005 LEVELS Our business plan raises the bar on environmental improvements, including actions to reduce risks and improve our performance. To support this focus, we’ve identified milestones through 2025 to reduce our methane and electric generation greenhouse gas emissions, water withdrawals, wastewater discharge and coal ash generated. These proactive initiatives, which include retiring half of our coal-fired electric generation fleet by the end of 2023, are expected to reduce emissions to a level exceeding the goals of the Paris Agreement and the Clean Power Plan. The impact is significant. In practical terms, we’re reducing our greenhouse gas emissions (including methane) to a level equivalent to removing more than 8 million cars from the road annually. The water we’ll save equals what 1 million typical households use in a year. While these targets are aggressive, they are within our reach, and we’re already making 11 90% NITROGEN OXIDES, SULFUR DIOXIDE & MERCURY 90% WATER WITHDRAWAL 90% WASTEWATER DISCHARGE 60% COAL ASH GENERATED 50% CARBON DIOXIDE (FOR ELECTRIC GENERATION) 50% METHANE ON TRACK ON TRACK ON TRACK ON TRACK ON TRACK ON TRACK IN 2017, CUSTOMERS GENERATED MORE THAN 114,000 MEGAWATT HOURS FROM RENEWABLE RESOURCES, AND MORE THAN 473,000 MEGAWATT HOURS SINCE 2011 (VIA FEED-IN TARIFFS) See Sustainability Scorecard on NiSource.com/Sustainability for more details.
