Tullow Oil...has signed contracts with the Ugandan government allowing it to flare gas with the potential to release huge volumes of greenhouse gases into the atmosphere, according to a report by non-governmental organisations. The production-sharing agreement also appears to carry few specific safeguards in the event of spills or other environmental damage and is too financially weighted in favour of Tullow, says the study by the UK-based NGO Platform, which is working in Uganda with the Civil Society Coalition on Oil...Tullow said it could not comment directly on the agreement because it had to abide by the Ugandan government's wishes that it be kept confidential.
