To mitigate the hazardous climate changes, Dane Baker and Peter Twomey have developed EcoCart. EcoCart is a Chrome extension that helps consumers offset their carbon footprints during online shopping. 500 other startups have already backed the San Francisco-based startup. Shopify estimated in one of its reports that global e-commerce sales were $3.5 trillion in 2019 and will grow to $6.5 trillion by 2023. The carbon offset market has two major sections: Compliance offset and Voluntary offset. S&P Global describes the compliance segment of carbon offsets to be around $44 billion in 2018. However, Vox reported that the voluntary offset market was approximately $300 million in 2018. Shoppers download the Chrome add on EcoCart extension. While shopping at EcoCart member stores, the extension will pop up, helping consumers pay the estimated carbon footprint during checkout.
