GM implemented over 250 global energy savings projects and initiatives in 2018 resulting in 580 GWh of reduction or 3 percent absolute. Unfortunately with 5 percent volume reduction and a large number of product launches, our energy intensity increased by 3.7 percent from 2017. With increased plans for Energy Performance Contracting, we expect to return to our pathway to 2020.
We have already exceeded the 2020 goal and are working toward a new target of meeting 100 percent of the electrical needs of our global operations through renewable energy by 2050. We are approximately 20 percent of the way toward this new goal.
GM met our Scope 1 and 2 GHG 2020 goal in 2017 and developed an absolute goal to 2010-2030, based on science, to limit global temperature rise to below 2 degrees Celsius above pre-industrial levels. Energy efficiency in our operations and RE100 provide the methods to meet our goal.
Similar to energy, with a reduction in production volume of 5 percent, even with water conservation projects implemented, GM had a 0.6 percent intensity increase. Our plan to meet the pathway to 2020 is to use Water Performance Contracting.
A new Sustainable Materials Management function is allowing us to continually reduce waste through design, materials selection and repurposing of items that would otherwise go to waste.
Manufacturing actions taken as part of GM’s transformation led to several plants being unallocated, which in turn decreased our total number of landfill-free sites.
Though we achieved our commitment in 2013, we continue to lower VOC emissions annually.
We were gratified to add four new certified wildlife habitats during 2018, thanks to the commitment and enthusiasm of our manufacturing employees and leadership. We are currently at nearly 85 percent of our goal.
