Cutting Emissions Through Fossil Fuel Subsidy Reform and Taxation
Using the Global Subsidies Initiative – Integrated Fiscal Model (GSI-IF model), this report models the impact of fossil fuel subsidy reform (FFSR) on greenhouse gas (GHG) emission reductions for the following 32 countries: Algeria, Argentina, Australia, Bangladesh, Brazil, Canada, China, Egypt, Ethiopia, Germany, Ghana, India, Indonesia, Iran, Iraq, Japan, Mexico, Morocco, Myanmar, Nigeria, Pakistan, Russia, Saudi Arabia, South Africa, Sri Lanka, Tunisia, United Arab Emirates, the United States, Venezuela, Vietnam, the Netherlands, and Zambia. In total, these 32 countries accounted for 77% of global carbon dioxide emissions, 72% of global GDP, and 72% of the global population in 2019.
The GSI-IF model uses semi-continuous simulations to forecast energy demand and corresponding GHG emissions. It considers the gradual removal of all fossil fuel subsidies to consumers until 2030, a gradual introduction of a 10% fossil energy tax until 2030, and the investment of 30% of both subsidy savings and tax revenues to energy efficiency and renewable energy from 2021, respectively 2026, onwards.
The research finds a simple country average in GHG emission reductions of about 6% by 2030 compared to business as usual, while the data shows that FFSR can reduce as much as 35% of emissions in the countries modelled. Adding emission reductions from the fossil energy tax as well as the investments of parts of the subsidy savings and tax revenues into sustainable energy would almost double the average GHG emission reductions to 11.8% by 2030. Cumulative fiscal savings from FFSR alone by 2030 total close to USD 3 trillion across the countries analyzed, with total cumulative GHG emissions abated from FFSR of 5.4 gigatonnes of carbon dioxide equivalent (GtCO2e) by 2030—equivalent to the annual emissions of about 1,000 coal-fired power plants or 3.8 billion cars. For every tonne of CO2e removed through FFSR alone, governments save about USD 546.47 on average. When considering the resources reallocated via the subsidy swap, governments can increase their emission reductions and still save USD 164 for every tonne of CO2e removed.

Canada to Cut Oil & Gas Subsidies
The Canadian federal government has implemented a framework to revoke subsidies for fossil fuels that are deemed inefficient. However, the framework lacks details on the specific subsidies to be eliminated and does not provide a dollar amount for the cuts. Canada, as the fourth-largest oil producer in the world, is the first country to comply with a 2009 pledge made by the Group of Twenty (G20) nations. The government plans to exempt oil and gas projects that have plans to reduce emissions and utilize carbon capture and storage (CCS) technology. Federal Environment Minister Steven Guilbeault stated that the objective is for federal support to be directed only towards projects that decarbonize the sector and result in significant greenhouse gas emissions reductions.
