How to Protect the Night Sky 

Light pollution is a widespread problem that is associated with many threats to human health and the environment, from disrupted circadian rhythms and insomnia to habitat destruction. Many environmental problems can seem insurmountable – issues like climate change and air pollution are often heavily associated with industrial and commercial operations and can’t be easily ameliorated by individual behavior changes. Light pollution, however, is different. There’s a lot you can do! You don’t need to earn a Dark Sky Place award to do great dark sky conservation work. Eliminating ineffective artificial light at night is as simple as flipping a switch. 

What can you do at home? 

First, take a look at how you are lighting the outside. Do you need to have the light on all the time? Is it too bright? Is the light trespassing on areas that are outside the intended need?  

Here are some aspects to consider when evaluating your outside lighting. 

• Use outdoor lighting fixtures that are designed to reduce light pollution.  DarkSky friendly lighting fixtures emit light only where it’s needed, reducing glare and light spill. These fixtures also help to reduce energy consumption, saving money on your electricity bill.
   
• Install motion sensors and timers. Motion sensors and timers can be used to automatically turn off lights when they are not needed, reducing unnecessary light pollution.
   
• Choose warm white light bulbs that are only as bright as is necessary.
   
• Turn off lights when not in use. Simply turning off lights when they are not needed can significantly reduce light pollution.
   
• Educate others about the importance of reducing light pollution and how to do it. Encourage your neighbors, local businesses, and government agencies to implement measures to reduce light pollution.
   
• Participate in local community initiatives and partner with organizations that promote reducing light pollution.  

Reducing light pollution is an ongoing process that requires awareness, education, and a commitment to preserving the natural environment. By taking steps to reduce light pollution, you can help to protect the night sky and promote a healthier and more sustainable community. Taking the initiative to make small changes at home will help you to See the Dark. 

What can you do in your community? 

If you’re interested in taking your community’s action to the next level, you might want to consider an International Dark Sky Places certification. DarkSky is the recognized authority on light pollution and the leading organization combating light pollution worldwide. Their purpose is to protect the night from light pollution. 

DarkSky’s conservation program recognizes and promotes excellent stewardship of the night sky. The program offers five certification categories you may consider; sanctuaries, parks, reserves, urban places, and communities. Each category has its own set of guidelines based on land management, size, and sky quality. Interested in applying? Learn more about the different designation types here. 

As of January 2023, there were over 201 certified dark sky places in the world. Check out DarkSky’s interactive map to see where they are located.  

Becoming a dark sky place requires a rigorous application process where applicants must demonstrate partner support, implement light pollution mitigation projects, and meet specific category requirements. You don’t have to think big to start – almost all dark sky conservation work starts with a committed group of individuals passionate about the dark sky!  

“By arranging for good outdoor lighting policies, rehabilitating poor-quality outdoor lighting installations, and reaching out to educate neighbors and visitors on the importance of dark skies, International Dark Sky Places (IDSP) set a positive example for their communities and countries.” – DarkSky.   

You can expect the entire application process to take about 1-3 years.  

To become an International Dark Sky Place, there are several steps: 

• Evaluate the darkness of the location.The first step is to evaluate the darkness of the location where you want to establish a Dark Sky Place. To do this, you can use tools like a sky quality meter or the DarkSky Meter app. These tools measure the level of light pollution in the area. You will need readings from multiple locations, during the new moon and when skies are clear is best. If your location is at or below the set level of light pollution, move on to the next step. If not, you can still work at the household and community level to reduce light pollution.
   
• Meet with DarkSky and share your interest. DarkSky’s formal support and close relationship will help you meet the application requirements. DarkSky will be with you the entire way from determining eligibility to application to successfully managing your certification. Typically, only applications that are complete and likely to be successful will be reviewed by DarkSky’s Committee for approval.  
   
• Develop a lighting plan.Once you have evaluated the darkness of the location, you need to develop a lighting plan that outlines the steps you will take to preserve the dark sky. This plan should address issues such as reducing light pollution, minimizing glare, and using efficient lighting fixtures.
   
• Work with the community. To become an International Dark Sky Place, you will need to work with your local community to gain support and participation in partnered projects. This can involve hosting public events, educating the community about the importance of preserving the dark sky, and working with local businesses and government agencies or your organizations leadership to implement the lighting plan.
   
• Apply for the designation.Once you have completed the above steps, you can apply for Dark Sky Place designation from DarkSky. The process involves submitting a comprehensive application that includes information about the location, lighting plan, community involvement, and other relevant factors.
   
• Maintain the designation. After receiving the designation, you will need to maintain your Dark Sky Place status by continuing to implement the lighting plan, monitoring light pollution levels, and engaging with the community to promote awareness and participation. 

Becoming a International Dark Sky Place is a significant achievement that requires a commitment to preserving the natural environment and reducing light pollution. It can help to promote eco-tourism and raise awareness about the importance of protecting the night sky.
