California is projected to be home to 50 million people by 2050.
The indicators hosted on this site are designed to give a snapshot of how California is doing across a series of environmental measures. We will be adding more over time, and encourage your suggestions for information that would be meaningful for you.
How are we doing?
California’s population will reach 50 million by 2050. At the same time, the population is aging and demographics are shifting. The location and characteristics of the State’s future population will affect environmental and economic outcomes, as well as affect demand for housing and transportation.
Our changing climate will continue to have impacts at every corner of California making it imperative that actions are being taken now and into the future to both reduce emissions and build resilience for the impacts to come.
Transportation is a part of every Californian’s daily routine and accounts for over 37% of California’s greenhouse gas emissions and is the largest source of smog-forming pollution in the State. Looking into the future, California will shift towards higher amounts of walking, biking and commuting to achieve both healthier communities and greenhouse gas reductions.
California’s leadership on energy efficiency has contributed to the State’s relatively low energy demand. Increased investment in energy efficiency and the use of clean, renewable energy sources are a major element of the State’s program to reduce greenhouse gas emissions.
California’s natural resources are critical elements of the State’s economy and way of life. Healthy natural systems provide recreational and economic benefits. Healthy and protected agricultural lands, forests, and watersheds are all essential to meeting the State’s environmental goals.
As our population grows, California must ensure that its communities are able to foster healthy and equitable living through increased housing affordability, reduced air pollution, increased active transportation, and reduced asthma rates.
