The Competitive Enterprise Institute advocates for free market reforms that ensure abundant and affordable energy and better protect our environment. CEI has been instrumental in fighting decades of climate alarmism and anti-energy policies that constrict energy supplies, raise prices, and stoke unjustified pessimism about human adaptive capabilities.
Conclusions of CEI’s research and analysis include: Abundant, affordable energy is a blessing underpinning the unprecedented improvements of the past two centuries in life expectancy, health, standards of living, food and nutrition, and industrial production. The climate catastrophe narrative is based on global climate models that inflate greenhouse gas emission scenarios and have been falsified by the past four decades of temperature data. The real costs of proposed solutions to the alleged crisis hugely exceed their hypothetical benefits.
Coalitions led by CEI were instrumental in defeating ratification of the 1997 Kyoto Protocol, defeating enactment of the 2009 Waxman-Markey cap-and-trade bill, and convincing President Trump to withdraw from the 2015 Paris climate treaty.
