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 group of companies and organizations spearheaded by Amazon, said Monday that it has signed up 86 new members for its voluntary measures.

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.

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