Cisco commits $100 million to fight climate change

• Most experts believe more aggressive global efforts are needed to avoid some of the greatest climate dangers.

Meanwhile, Cisco says that it is already using 100% renewable energy in several countries around the world and "is on track" to reach its goal of getting at least 85% of its global electricity from renewable sources by next year, among other targets.

• "We know that in order for us to live up to our purpose — to power an inclusive future for all — we must combat the rising inequality that stems from climate change," Cisco chief people, policy and purpose officer Fran Katsoudas said in a statement.
