Proving we care

The purchase of one pair of socks has the power to change our future.

The CARE certificate system has been created to ensure that companies and consumers alike are able to avoid ethical and environmental pitfalls. It is the first transparent initiative in manufacturing for the protection of human rights and the environment.

We are working towards a world that adheres to a fair labor standard and sustainable practices — one where everyone works and lives in safety. It is time to create a more equitable world where consumers and companies care about our future

A rigorous data collection and analysis process

We analyze companies’ products and services using 10 key metrics.
With the help of official reports from trustworthy organizations such as the UN, we assess data related to region, gender, age and educational background. We also mine real-time social media data. Before we sign off on our reports, we make sure a third-party has combed through the data to ensure complete accuracy.

Create a healthy work environment

  • 1. A fair work and labor environment

    We address the work environment from various angles — child labor, immigrant labor, forced labor, overwork, low-wage labor, and worker dismissal issues.

  • 2. A safe and healthy work environment

    Whether in developed or developing countries, a healthy work environment is critical for workers. Employers must protect their workers.

  • 3. Human rights for all

    The protection of human rights at work has become a key concern in all countries and organizations. While raising awareness of inherent labor rights and human dignity, we will also highlight companies that are working to improve their work environments.

  • 4. Social ethics in management

    Every year, trillions of dollars that should have been used for medical care and infrastructure development is lost to corruption worldwide. Shockingly, the sum is equal to about 5% of the world's gross domestic product. We keep watch to ensure that companies follow rigorous social, environmental, and economic standards.

  • 5. Medicine and education for all

    People work in environments without clean drinking water, and children work in rural areas without medical and educational institutions. We look at workers' livelihoods with access to local infrastructure such as clean water, hospitals, and schools that we take for granted.

Create a Sustainable Environment

  • 1. Being careful with finite resources

    Given the finite nature of non-renewable resources like oil and gas, we evaluate companies based on their efforts to transition to renewable energy sources and improve resource efficiency to address limited energy concerns.

  • 2. Preserving our planet for future generations

    Beyond environmental degradation, air and water pollution inflict significant health hazards. We evaluate companies based on their commitment to tackling these pressing concerns.

  • 3. Minimizing climate change

    Global warming-induced climate change poses a threat to the delicate balance of our shared environment, home to all living beings. We assess companies that advocate for the reduction of carbon dioxide and other greenhouse gases.

  • 4. Cherishing Mother Nature

    The natural splendor around us is under constant threat of vanishing. We scrutinize a company's approach to assess if it prioritizes the conservation of vital natural resources such as rivers, forests, and agricultural lands.

  • 5. Looking out for all living things

    Tens of thousands of species are facing the threat of extinction. We diligently monitor global activities to prevent environmental pollution and destructive development, safeguarding the safety and well-being of all living beings.

Global Industry Credibility
CARE Certificate:

We give awards to CARE-certified companies that help prove their
trustworthiness as organizations. Awards are only issued to companies that
have achieved a minimum score following a rigorous survey and analysis
process. A graph-derived flower symbol is printed on the certificate to
reflect each individual company’s rating.

4 types of Blossom Awards

There are four certified awards based on level of achievement for both the “Human Rights” and “Environment” sections: "Platinum Blossom," "Gold Blossom," "Silver Blossom," and "Bronze Blossom". Furthermore, the "Environment" section incorporates a "Carbon Offset" certification, which assesses greenhouse gas emissions. The flower symbol is based on the shape of the calculated data graph. The better the overall index value, the larger the flower symbol.
