The WECP is committed to a future of greener, safer energy, while meeting world energy needs. In 2009, WECP Member Cities signed the Calgary Climate Change Accord, establishing a commitment to reduce greenhouse gas emissions.
As part of its commitment to sustainability, every WECP Member City has established a sustainability office. Example of green energy initiatives in member cities include Esbjerg, Denmark, which has developed a green energy grid based primarily on wind energy, in addition to being a world leader in wind turbine technology. Stavanger, Norway has managed to create a 100% renewable energy system by harnessing water energy technology. Additionally, Houston itself is actually home to the largest electric car fleet in the world.
