The RE100 campaign, led by the Climate Group, has been confirmed as this year's winner of the British Renewable Energy award in the Pioneer category. The campaign was recognised for its work in accelerating corporate buy-in for the green energy agenda through commitments to 100pc adoption of renewables.

The RE100 campaign has been led by The Climate Group and CDP and has been working to stimulate businesses to take action - flagging up 100pc renewable adoption commitments of some of the biggest global brands across the world ever since its launch in 2014 with just 12 signed-up firms.

Now 65 global brands are involved in the campaign, and a raft of others are gearing up to join, proving the business imperative for green energy and sending a powerful signal to governments and utility firms alike.

The award was presented at a lavish gala dinner in London, and The Climate Group's Strategy Director, Damian Ryder, said that he was delighted to accept the award on behalf of the group, adding that those involved were delighted that the campaign had been recognised for its ground-breaking climate change work. He explained that the campaign gave committed firms a single powerful voice that policy-makers and the market were obliged to listen to.

Other firms were also recognised for their work in forging ahead with green energy usage. Marks & Spencer took home first prize in the leadership category for making renewable energy use an important goal and making a strategic effort to move away from fossil fuels across the business. Since 2012, M&S has been wholly powered by renewable energy in the UK, and it has invested over £500,000 in green energy projects through its M&S Energy business, helping British communities to benefit from sustainable energy schemes.
