24 - Integrating Climate into our Strategy Limiting Methane Emissions Natural gas will play a pivotal role in the fight against climate change. Substituting natural gas for all coal used in power generation would reduce global CO2 emissions by approximately 5 billion tons per year1, or around 10%. However, increasing the share of gas in the energy mix must go hand-in-hand with limiting methane emissions. Methane’s global warming potential is higher than that of carbon dioxide. To maintain the advantage gas offers over coal in terms of reduced greenhouse gas emissions when used in power generation, methane emissions associated with its production and transportation must be limited. Methane emissions in our operated scope stood at 2.3 Mt CO2-eq in 2015. Nearly half, or 1.1 Mt CO2-eq, were specifically related to gas production. In all, they account for less than 0.5% of Total’s marketed operated production. Improving methane measurement and mitigating these emissions are environmental priorities for Total.
