Walmart is doubling down on its climate commitment. Today, the retail giant announced Project Gigaton, a goal to remove 1 billion metric tons of greenhouse gases from its supply chain by 2030, equivalent to taking more than 211 million passenger vehicles off the road for a year, the company said.

The focus is on Scope 3 emissions — those that are a consequence of business operations but over which it doesn’t have direct control. It is launching an online toolkit for suppliers seeking to better manage energy, agriculture, waste, packaging and deforestation, and to design consumer products with a lower impact — for example, LED light bulbs and apparel that’s washable in cold water.

Every gigaton counts: The entire global carbon emissions from fossil fuel use in 2014 was 9.75 gigatons. Within the next decade, the world must not exceed a carbon budget of 335 gigatons annually in order to limit global warming to 2 degrees Celsius and achieve the Paris Agreement goals.
