 Climate pledges about cutting emissions and reducing carbon by of the worlds largest companies, including Amazon, GlaxoSmithKline PLC LSE:GSK, Unilever PLC LSE:ULVR and Nestlé are not quite what they are made out to be, according to new analysis. While the big 25 have promised to reduce emissions by 100, as suggested by their net zero and carbon neutral claims, in reality the measures they have set out only commit to reduce their emissions by 40 on average, a report by the NewClimate Institute in collaboration with Carbon Market Watch has found.
