BERLIN -- Computer-maker HP, consumer goods business Procter & Gamble and coffee capsule company Nespresso have joined a corporate pledge to sharply cut their greenhouse gas emissions over nearly two decades.

       The Climate Pledge, a grouping of companies and organizations spearheaded by Amazon, said Monday that it has signed up 86 new members for its voluntary measures. In total, the group now has 201 members with global annual revenues of more than $1.8 trillion, it said.

       Other new members include telecoms company BT, truck-maker Scania and the Selfridges department store chain.

       Together, the companies aim to cut almost 2 billion metric tons of carbon dioxide by 2040 — more than 5% of the current global total.

       While the group's members are encouraged to eliminate as many emissions as possible, those that can't be avoided need to be completely offset in the next two decades. That means paying for measures to ensure as many emissions are absorbed by then as the companies continue to emit.

       Scientists say the world needs to achieve ‘net zero’ emissions by 2050 if it wants to meet the Paris climate accord's goal of keeping temperatures from rising more than 1.5 degrees Celsius (2.7 Fahrenheit) by the end of the century compared to pre-industrial times.
