What it's about:
Portland and Multnomah County in the United States have announced they will be transitioning to 100 percent renewable energy sources by 2050.
The ambitious targets aim to ensure that electricity needs are met from renewable sources by 2035 and that all remaining energy sources shift to renewables by 2050.
As the largest city in the state of Oregon, Portland was the first U.S. city to adopt a carbon reduction strategy in 1993. It has since gained a reputation within the United States for being at the forefront of the battle against climate change.
Portland’s mayor also said he plans to resist any federal policy changes that could increase carbon emissions, adding to views that the onus to fight climate change will increasingly be placed on cities.
Why it's noteworthy:
A number of other cities in the United States have also committed to 100-percent renewable targets - most recently Chicago, where the mayor announced that all city buildings would be powered with renewable energy sources by 2025.
A handful of American companies, such as Google, Coca Cola and Nike, have made similar pledges too.
