Liverpool City Council has partnered with the Poseidon Foundation to help offset its carbon emissions. The year-long trial is intended to help Liverpool become the first local authority in the UK to become ‘climate positive’.This means that the city will help remove more carbon dioxide from the atmosphere than it emits each year. Finance start-up Poseidon will incorporate its block chain technology into the council’s day-to-day operations to help offset more than 110 percent of its emissions. The sum of Liverpool’s entire carbon emissions is first priced and the cost passed on to purchase carbon credits, certificates which are tradable and internationally recognised in financial markets. The non-profit will use these credits to support forestry conservation projects to reverse the environmental impact of the city’s every day activities, particularly its carbon intensive shipping and aviation sectors. If the trial is successful the council will utilise the technology to become climate positive across the whole city by the end of 2020.
