ASLA Launches Guide to Climate Change Mitigation

Global climate change is the defining environmental issue of our time. From devastating wildfires to historic storms and rising seas, the effects are already being felt and will continue to get worse. According to NASA, sea levels could rise anywhere from 8 inches to 6.5 feet by 2100. Additional impacts include increased spread of diseases; extensive species extinction; mass human, animal, and plant migrations; and resource wars over dwindling food and water supplies. Furthermore, these impacts will disproportionately affect the world’s poorest and most vulnerable communities.

Sustained, meaningful commitments and actions to substantially reduce greenhouse gas (GHG) emissions from all sectors of our economy can help avoid the worst of these negative impacts. The benefits of these actions will be measured in lives saved and communities spared.

In 2015, the international community gathered in Paris, France, and agreed to a landmark cooperative framework for limiting global temperature rise to “well below” 2 degrees Celsius above pre-industrial levels. In order to meet this goal, GHG emissions will need to peak by 2020 and fall to zero by 2050. This is an immense goal, but also achievable.

Landscape architects are helping to shift us to a carbon neutral future. Landscape architects plan and design dense, walkable communities that reduce emissions from transportation and sprawl. They make the built environment more energy and carbon efficient with strategies like green roofs, water-efficient design, and use of sustainable materials and construction practices. They defend and expand carbon-sequestering landscapes such as forests, wetlands, and grasslands, helping to drawdown atmospheric carbon dioxide. All of these efforts also enable communities to better adapt to climate change and improve their resilience.

The threats posed by climate change are immense, and there is no single strategy that will solve the climate crisis on its own. Instead, mitigation requires an “all hands on deck” approach as we seek to reduce GHG emissions wherever possible. Achieving a carbon neutral future will only come about through the cumulative effect of countless individual actions. Every one of those individual actions counts.

Explore the new ASLA guide to climate change mitigation, which complements Smart Policies for a Changing Climate, the report and recommendations of the ASLA Blue Ribbon Panel on Climate Change and Resilience.

Sections of the mitigation guide include: regions, cities, materials and construction, green infrastructure, and natural systems.

    Good to see that people and organizations are still on the “mitigation” bandwagon, but this late in the climate change game, it might be best to concentrate on adaptation strategies for designing communities and site development and build more resilient landscapes that can survive the coming changes. There are a lot of carbon lessening mitigation strategies already being implemented based primarily on economics across many parts of the country, many at-risk communities need to adopt new land use and building ordinances that allow existing development and new development to adapt to coming changes as they occur, response to the changes will be a key to reducing impacts.
