Impact Calendar: The Ultimate List of Social and Environmental Awareness Days

Impact Calendar: The Ultimate List of Social and Environmental Awareness Days

By 3P Insights

From climate to wellness to animals, and everything in between, there are loads of social and environmental awareness days worldwide that may be uniquely aligned with your brand. While most of us already know about national holidays like Labor Day or Independence Day, organizations like the United Nations, as well as smaller NGOs and nonprofits, have created several observance days to share the importance and appreciation of our beautiful planet and the people living on it.

Celebrating Social and Environmental Impact

Celebrating days that align with your organization’s mission, values, and purpose can unite your stakeholders, creating a shared sense of purpose around your brand among customers, employees, and your community. Creating content around these holidays can also be a valuable part of your social media strategy.

Social media managers are always looking for opportunities to leverage trends for brand awareness. Using hashtags like #EarthDay or #BreastCancerAwareness can give your social media content a boost, helping you capitalize on the growing interest in sustainable and inclusive lifestyles while improving your reach. Using social media to recognize social and environmental awareness days is also a great way to increase knowledge about important causes, while empowering your stakeholders to act. In this way, creating educational content around social and environmental causes that matter to your brand (and your target market) can be a powerful form of advocacy advertising.

To help you plan for trending holidays and workplace celebrations, we created a comprehensive list to get you started. While we certainly don’t think your brand should celebrate every one of them, this list offers opportunities to communicate your commitment to sustainability throughout the year.

Some of the holidays listed are specific to the United States, while others are internationally recognized. Click on the links to learn more about each and be sure to bookmark this page. The calendar will be updated so you can plan your celebrations in advance!
