Amazon.com Inc. has added a competitor to its year-old coalition of companies pledging to reduce their contribution to climate change: Microsoft Corp.
The two technology giants, neighbors in the Seattle area and rivals in cloud computing and business software, have each spent much of the last two years announcing increasingly aggressive climate targets, including dueling umbrella organizations for companies willing to do their part to avert the catastrophic warming of the planet. On Wednesday, Microsoft said it had signed onto Amazon’s pact, alongside consumer products giant Unilever Plc and several other new signatories.
