                Automobile Inspections

                Since 1 January 1995, a safety inspection is required every two years for gasoline and diesel vehicles over four years old. The inspection includes carbon monoxide emissions (gasoline) and exhaust fumes (diesel). Repairs are mandatory for vehicles that fail pollutant emission tests. The inspections are thought to increase fuel efficiency by improving the tuning of automobile engines to pass the emissions tests.

                …to expanding the production and use of renewable alternatives to gasoline and diesel, such as ethanol and biodiesel. They can diversify our energy mix and contribute to reductions in greenhouse gas emissions, while at the same time providing new opportunities for the agricultural sector. The ecoENERGY for Biofuels Program is a key component of the renewable fuels strategy, and provides up to CAD 1.5 billion over nine years to encourage investment in the biofuels industry and to boost Canada’s capacity to produce renewable fuels. The Program offers operating incentives to producers of renewable alternatives to gasoline and diesel…

                Biodiesel blending mandate

                In 2012 the Energy Policy and Planning Office Ministry of Energy introduced domestic blending mandate of 5% biodiesel blend in diesel fuel. On 1st of January 2014 the biodiesel blending mandate was increased to 7%. The goal is to reach 10% blend by 2019.

                Excise tax rebates for biofuels

                …biofuels blended with petrol and diesel as well as those used as pure fuels for transport benefit from excise tax reductions in the form of rebates. Blended end products comprise petrol blends with ethanol, bioethanol derivatives ETBE and TAEE, and diesel blends with esters. Petrol and diesel blends must contain at least 2% biofuel to benefit from the excise tax rebate. Biofuels sold to producers of biofuel blends are fully exempt from excise tax. More specifically, petrol biofuel blends benefit from a PLN 1500 per 1000 litres rebate (normal rate PLN 1565/1000L), while diesel biofuel blends benefit from a…

                Budget 2002 introduced a 20 pence per litre (ppl) cut in the duty rate for biodiesel compared to ultra-low sulphur diesel. This came into effect on 26 July 2002. The Chancellor announced in Budget 2003 that the Government will reduce the duty rate for bioethanol by 20 ppl compared to ultra-low sulphur petrol with effect from 1 January 2005. Further support was announced in Budget 2004 with a commitment to maintain the 20 pence per litre duty rate cut for biodiesel and bioethanol until at least 2007; to discuss with stakeholders the implications of input-based taxation for…

                Biodiesel blending requirement

                In February 2009, Decree Law 49/2009 instituted mandatory quotas for use of biofuel in diesel blends, requiring that these contain at least 6% biodiesel (B-6). The quota is to rise to 10% in 2010. The law establishes the use of Biofuel Certificates (CdB) for compliance purposes. The General Directorate of Energy and Geology (DGEG) will issue one CdB to producers for every 1000 litres of biofuel destined to substitute for fossil fuels in the transportation sector. Diesel distributors must register with the DGEG and demonstrate ownership of sufficient certificates to comply with the minimum biofuel quota. The DGEG…
