In total, these companies have committed $100 million to the project, hoping to “accelerate the reduction” of superpollutants like methane, black carbon and refrigerant gases. Google says these are responsible for of all planetary warming.

“Superpollutants are a major part of the equation to limit atmospheric warming. Experts agree that eliminating them where we can is one of the most powerful levers we have to deliver near-term impact, playing a vital and complementary role to removing CO2,” said Randy Spock, Google’s carbon credits and removals lead. The gases break down faster than CO2 but can trap heat thousands of times more efficiently, and the coalition claims that aggressive action could prevent more than half a degree Celsius of warming by 2050.

Alphabet, Google’s parent company, $132 billion in net income in 2025. Google’s five-year, $50 million pledge works out to about three hours of that. The company is also set to building massive data centers for AI that it claims are than others. So far, Google’s AI infrastructure buildout drove an in the company’s total emissions last year.
