A review of the evidence to monitor greenhouse gas emissions

Tender description

The aim of this project is to perform two rapid evidence assessments (REAs) to collate, review and critically appraise information and data to: (1) understand the possible scale of the reduction of greenhouse gas (GHG; nitrous oxide (NO2), methane (CH4) and carbon dioxide (CO2)) emissions more accurately from municipal wastewater treatment including an evaluation of benefits and costs; and (2) identify and recommend where the biggest opportunities for emission reductions can be made within the treatment of industrial wastewaters and which are reported in the UK GHG Inventory (GHGI), and where feasible, wastewaters collected and treated in privately-owned septic tanks and package treatment works. The objective is to provide the Department for Environment, Food and Rural Affairs (Defra) with a synthesis of evidence to aid its design and implementation of short-term research programmes to support the wastewater sector tackle its GHG emissions. A report will be prepared which succinctly summarises the current evidence, describes those best practices performed at the international level and recommends a broad overview of policy options for the short-to-near term future.
