In a recent press release, the ASLA announced its involvement with We Are Still In, a national coalition of 3,500 states, cities, companies and organizations that are still committed to hitting the target rates of greenhouse gas reduction in the U.S. that were outlined as part of the 2015 Paris climate agreement. With this move, ASLA leadership has labeled climate change as a strategic focus.

On September 12, executive vice president and ASLA CEO, Nancy Somerville, attended the We Are Still In Forum in San Francisco as part of the Global Climate Action Summit. This was reportedly the first climate summit at which leaders from both the private sector and local government engaged in discussion to "highlight meaningful solutions to climate change and raise the bar for action."

In joining this coalition, the ASLA continues to encourage landscape architects to use their expertise in planning and design to address issues surrounding climate and sustainability on a national and local scale.
