The Standard has joined forces with Greenhouse Sports to deliver sports coaching and mentoring to young people in secondary schools across some of London’s most deprived boroughs. So far, £500,000 has been raised, with £250,000 going to Greenhouse Sports programmes in London and £250,000 to four other youth charities across the capital, including Carney’s Community. We are calling on corporations, foundations, philanthropists — and our readers — to donate. All funds raised will go to Greenhouse Sports programmes in London.
