The cost to transition the world to net zero emissions by the year 2050 is approximately 1 to 2 trillion dollars per year. Climate change: Net zero emissions could cost $2 trillion a year, ETC report says - CNN Achieving net zero greenhouse gas emissions by 2050 is possible but will cost $1 trillion to $2 trillion a year, according to a new report, which warns that the cost of unmitigated climate change will be much higher. The Energy Transitions Commission, a coalition of senior executives from 45 energy producers, financial institutions and environmental groups, said Wednesday that it is "technically and economically possible" to achieve net zero emissions by the middle of the century at an annual cost of about 1% to 1.5% of global GDP. Limiting global temperature increases to 1.5 degrees Celsius, a goal of the Paris Climate Agreement, will require net zero emissions by around 2050. The required additional investments are "easily affordable," given current global savings and sustained low interest rates, and are dwarfed by the amount of public spending dedicated to stimulating the economy after the coronavirus pandemic, the ETC added.
