A new signature event for Earth Month, Carbon Free Day on April 17, encourages the Arizona State University community to make small changes that can add up to make a big difference in the fight against climate change. On Carbon Free day, ASU will be purchasing carbon offsets and planting 218 trees to mitigate the university’s emissions for the day. University Sustainability Practices is asking students, staff, faculty and the wider ASU community to join the commitment by making a pledge to reduce carbon emissions. Pledges run the gamut from transportation to food to energy, or participants can create their own. ASU is committed to becoming climate positive by 2035. The university has made great strides to reduce its carbon emissions since making that pledge. Total emissions are down 28% compared with a 2007 baseline. “That’s despite the fact we’ve added over 40% gross square footage and almost 31% in our student population in that same period,” said Corey Hawkey, assistant director of University Sustainability Practices. “We’re on the path to meet our goal, but there is still work to be done. It’s part of the reason we’re doing this day. … We’ve made great progress, and it’s something we should all be appreciative of.” Read more about Carbon Free Day on ASU Now, sign a pledge to reduce your carbon emissions, or learn more about Earth Month events from the Julie Ann Wrigley Global Institute of Sustainability.
