A number of environmental experts have said that major international companies are not fulfilling their commitments to reduce harmful emissions, reports AFP.

The agency cites analytical reports prepared by the Carbon Market Watch and the NewClimate Institute. Over the past few years, under growing pressure from shareholders, governments and consumers, companies have sought to implement strategies to reduce carbon dioxide emissions. UN experts calculate that it will be necessary to reduce global greenhouse gas emissions by 45 percent by 2030 and achieve "net zero" - and remove all excess carbon from the atmosphere artificially. "Net Zero" is the name adopted in Western publicism for stopping carbon dioxide emissions or compensating for one's emissions by absorbing them from the atmosphere.

According to experts' findings, the 22 companies that have made such commitments actually plan to reduce their collective emissions by only 15 percent by 2030.

The vast majority of these corporations are simply not keeping those promises, according to experts at the Corporate Climate Responsibility Monitor. According to Carbon Market Watch, many companies make vague and misleading "net zero" promises to give their brands a greener image while continuing to do business as usual.

The best overall marks went to shipping giant Maersk, whose plan to get rid of its carbon footprint by 2040 was deemed fair enough. The climate plans of eight corporate giants, including Apple, Google, Microsoft and steel conglomerate ArcelorMittal, were deemed satisfactorily bona fide.

The plans of 11 major companies, including American Airlines, Samsung Electronics, grocery chain Carrefour and meatpacking giant JBS, were found by experts to be in bad faith. All four of these companies disagreed with this assessment.
