Plans to abolish air passenger duty in Scotland have been met with a mixed response.
The Scottish government has published responses to a three-month consultation on proposals to cut and replace the duty from 2018.
Almost half of the responses expressed concerns, with the majority centred on environmental issues.
The tax was devolved to the Scottish government following last year’s referendum result, with the SNP vowing to reduce the tax from April 2018 before abolishing it entirely "when public finances allow".
Scottish green party member Andy Wightman said: "It's disappointing that the finance minister is not heeding the concerns being expressed in this consultation.
"The Scottish government seems intent on pressing ahead but there is clearly not a majority in parliament for scrapping APD.
"Ministers would do well to consider ways to use the new tax powers to promote social justice rather than simply giving a tax break to an already under-taxed heavily-polluting industry and wealthy frequent fliers."
Scottish Labour also called for the APD proposals to be scrapped.
Transport spokesman Neil Bibby said: "Labour have argued for years that cutting Air Passenger Duty won't make Scotland fairer or greener.
"An APD cut is the wrong priority at the wrong time, and now the SNP government's own consultation agrees with us. This is a major embarrassment for the SNP."
However, finance secretary Derek Mackay said the tax continues to “act as a barrier” to investment into Scotland.
Our plan, taking into account the responses to the consultations, will be to start reducing the overall burden of a new tax in Scotland from April 2018, implement a 50% reduction in full by the end of the current Scottish Parliament, and then abolish the tax entirely when public finances allow.
"This a fundamental component of our efforts to boost Scotland's economy through improving international connectivity and generating sustainable growth."
