Australian Greens Leader Christine Milne says the Liberal Party's push to remove the charitable status of environment groups amounts to an attack on democracy.
"This is an extension of the Abbott government's ideological attack on the environment," said Senator Milne.
"Tax deductibility should apply to all groups that benefit the community and it's not fair for the Liberals to blacklist environmental groups just because they don't like what they stand for.
"Environment groups have played a vital role in protecting Australia's precious places. The community wants to support them and they should be eligible for tax deductibility.
"The hard-right Institute of Public Affairs that's setting the Abbott government's agenda receives tax-deductible donations. Groups with thousands of members who are acting in the community and national interest to protect to the environment that sustains life should be eligible too.
"This is part of the Abbott government's total assault on the environment, which sees them handing environmental approvals back to the states, defunding Environmental Defender's Offices, trying to open World Heritage forests to logging, introducing mandatory prison terms for environmental protest and approving coal ports and mines.
"It's not surprising, but it is disgraceful that the Liberal party in Australia wants to take away tax the tax deductibility of environmental groups, punish and persecute them, and destroy the environment as quickly as possible," Senator Milne said.
