Alliant Energy showed its progress toward a sustainable future by reducing carbon emissions 34 percent since 2005 and increasing its investments in renewable energy. The company also cut fossil fuel generation water withdrawals by over 25 percent since 2005 with plans targeting a reduction of 75 percent by 2030.

Alliant Energy issued its 2017 Corporate Sustainability Report detailing the achieved results as it balances its energy portfolio to include even more clean energy resources and highlighting its collaborative stewardship efforts with customers, communities and employees. The report is available at alliantenergy.com/sustainability. Balancing economic, social and environmental factors remains an integral part of the company's operations and strategic plan.

"Sustainability means doing the right thing with an eye toward the long run," said Alliant Energy's Chairman, President and Chief Executive Officer Patricia Kampling. "So our sustainability strategy looks into the future, promoting responsible company growth through the economic, social and environmental decisions we make today."

The company is transforming its generation profile to meet future customer needs in a sustainable way. Between 2005 and 2018, Alliant Energy will have permanently retired nearly 1,000 megawatts of coal-fired generation, and the company is planning to add over 1,000 megawatts of new, low-cost wind capacity by 2020. Cleaner natural gas facilities are also being brought into Alliant Energy's resource mix. Wind works hand-in-hand with natural gas facilities, which can adjust up and down quickly to provide reliable power as the wind increases or decreases. 

In 2016, renewable energy made up 15 percent of Alliant Energy's rated electric capacity. By 2024, that is expected to nearly double as the company pursues new investments in wind and other renewable generation. 

Key sustainability report highlights include:

• Saving over 212,000 megawatt-hours of electricity and over 4.3 million therms of natural gas in 2016 through investments in energy-efficiency programs. This is the equivalent of removing the greenhouse gas emissions from over 36,000 passenger vehicles driven for one year. 
• Launching Iowa's largest solar project in Dubuque, which will include a pollinator-friendly prairie and have 20 beehives maintained by a local beekeeper. 
• Reducing the emission of sulfur dioxide by 83 percent, nitrogen oxides by 76 percent and mercury by 95 percent since 2005. 
• Earning the first-ever EnvisionTM Platinum Award in Iowa for the new Marshalltown Generating Station. Envision is a sustainability rating system that evaluates an infrastructure project from design through construction and maintenance. 
• Partnering with a college to transfer building ownership of a former Wisconsin coal-fired facility to allow its redevelopment into a student union and recreational facility. 
• Investing in land options to create the Big Cedar Industrial Center in Iowa to bring new jobs and investment to the communities Alliant Energy serves. 
• Giving more than $6 million in 2016 by the company and employees to support communities. 
• Contributing more than $2 million to the Alliant Energy Hometown Care Energy Fund to help keep families safe and warm. 
• Accomplishing gender parity on the Alliant Energy Board of Directors with 50 percent of members being women directors.
