The debate about saving the environment is being held by and for white middle class people, ethnic minority community leaders have said.
Growing organic food will be among green initiatives celebrated
They say respect for the environment is at the heart of the Sikh, Hindu and Rastafarian religions but that their beliefs are treated as "hippyish".
The concerns will be raised at a London Sustainability Week conference.
The conference is billed as a celebration of the work that non-white communities do in the environment.
It will celebrate everything from recycling, composting and growing organic food to, in one case, planting a wood of 300 trees in Nottingham.
But community leaders are frustrated by what they say is a combination of impenetrable red tape and unhelpful officials.
