40 of the world's 100 largest private firms have not set net-zero carbon emissions targets, lagging far behind public companies, according to a report by Net Zero Tracker. The report highlights the need for all companies to address climate change, as required by the 2015 Paris Agreement. The slow uptake of climate commitments by private firms is attributed to a lack of market and reputational pressures, as well as a scarcity of regulation.
