20 companies tackling climate change

Top 20



8 minutes

For our first top 20 of 2022, we’re taking a deep dive into the businesses working to turn the tide on climate change.  

The EU has identified the top three causes of climate change as fossil fuels and carbon emissions, deforestation, and livestock farming. There are numerous sources for fossil fuels but the most significant are electricity and other energy types, transportation, and land use for food. These are also sources of carbon emissions, but one source that is a massive contributor but not commonly recognized is plastic pollution. Plastic is broken down by sunlight just enough to release greenhouse gases and does so for its entire lifetime in the environment like rivers, lakes, and oceans.  

This year’s forecast suggests that 2022 will be one of the Earth’s hottest years. Around the world, we are seeing the impact of global warming and climate change in unprecedented heat, weather patterns like hurricanes and wildfires, and continued and worsening droughts. But we haven’t given up yet and these 20 companies are working to fight against climate change and to create a greener world for future generations. 




Deforestation and carbon footprints 

CO2 emissions is one of the top contributors to climate change and is only exaggerated by the loss of the planet’s natural CO2 absorbers, trees. In order to counteract the negative impacts of carbon emissions we need to not only reduce our carbon footprint, but support the restoration of Earth’s forests to absorb what CO2 we still produce and we can do so thanks to companies like these.

Water pollution  

Plastic is a problem for a number of reasons, but in regards to climate change plastic in the ocean is increasing the amount of fossil fuels and CO2 released into the atmosphere. The conditions of water (oceans, rivers, lakes, etc) exacerbate the methane and ethylene produced from plastic that breaks down in the sun. Not to mention the damage it does to wildlife. These companies are cleaning up the plastic to improve all our chances.
