A proposal means jack really. President Trump has proposed bringing back 100% M&E deduction, doesn't mean it has or will happen.
Is this what you're referring to? Found this on the IRS website. I'm not familiar with conservation easements, but it sounds like taxpayers have abused this deduction or blatantly disregarded zoning laws and misused the land for what it was intended for.
Background - Abusive Transactions Involving Charitable Contributions of Easements
In recognition of our need to preserve our heritage, Congress allowed an income tax deduction for owners of significant property who give up certain rights of ownership to preserve their land or buildings for future generations.
"The IRS has seen abuses of this tax provision that compromise the policy Congress intended to promote. We have seen taxpayers, often encouraged by promoters and armed with questionable appraisals, take inappropriately large deductions for easements. In some cases, taxpayers claim deductions when they are not entitled to any deduction at all (for example, when taxpayers fail to comply with the law and regulations governing deductions for contributions of conservation easements). Also, taxpayers have sometimes used or developed these properties in a manner inconsistent with section 501(c)(3). In other cases, the charity has allowed property owners to modify the easement or develop the land in a manner inconsistent with the easement’s restrictions."
