At the end of July, JPMorgan Chase said that it would source renewable power for all of its worldwide energy needs by the year 2020. The bank also said it would facilitate $200 billion in clean financing through 2025.
"Business must play a leadership role in creating solutions that protect the environment and grow the economy," Jamie Dimon, JPMorgan Chase's chairman and CEO, said at the time.
JPMorgan Chase is the latest in a long list of big financial institutions to make a commitment to renewables.
Other banks have sought to highlight their commitment to the environment by joining the RE100, an initiative made up of some of the planet's biggest businesses, all committed to renewable energy.
Here, CNBC takes a look at 10 banks that have joined the group.

According to Spain's Bankia, in 2016 all of the electricity used by its branches and central services came from renewable sources.

Amalgamated Bank, which has committed to 100 percent renewable energy, announced it would be joining the RE100 in September 2016.
"We need to be honest, we have a growing environmental crisis unfolding and Amalgamated Bank will no longer sit on the sideline," Keith Mestrich, president and CEO of Amalgamated Bank, said at the time.
"As an industry that prides itself on innovation and bold action, we must all be leaders and take real action to change our course," Mestrich added.
