Getting the right picture of decarbonization
When any group publishes future energy scenarios, it’s useful to have a transparent way to make an apples-to-apples comparison and evaluate the temperature implications. Most of the corporate scenarios, with the exception of Shell’s Sky 1.5 scenario, don’t extend beyond midcentury and focus on carbon dioxide without assessing other greenhouse gases.
Our method uses a transparent procedure to extend each pathway to 2100 and estimate emissions of other gases, which allows us to calculate the temperature outcomes of these scenarios usingWithout a consistent basis for comparison, there is a risk that policymakers and businesses will have an inaccurate picture about the pathways available for decarbonizing economies.1.
, and people are suffering through deadly heat waves, droughts, wildfires and extreme storms linked to climate change. There is little room for false starts and dead-ends as countries transform their energy, agricultural and industrial systems on the way to net-zero greenhouse gas emissions.
