Climate-change mitigation

Definition

Climate-change mitigation encompasses policies and activities intended to reduce the greenhouse gas forcing of the climate system. Key intervention points include: the reduction of greenhouse gas sources, for example by reducing deforestation; emissions, for instance low carbon energy generation; and enhancing greenhouse gas sinks, for example by changes in land use.

    Scenarios have supported assessments of the IPCC for decades. A new scenario ensemble and a suite of visualization and analysis tools is now made available alongside the IPCC 1.5 °C Special Report to improve transparency and re-use of scenario data across research communities.

    Climate change mitigation scenarios are finding a wider set of users, including companies and financial institutions. Increased collaboration between scenario producers and these new communities will be mutually beneficial, educating companies and investors on climate risks while grounding climate science in real-world needs.

    Climate change will almost certainly cause millions of deaths. Climate engineering might prevent this, but benefits — and risks — remain mostly unevaluated. Now is the time to bring planetary health research into climate engineering conversations.

    In line with the principle of ‘common but differentiated responsibilities’, advantaged individuals recognize their privileged position and work to avoid collapsing a common pool resource, but they will not accept excessive free-riding by poorer individuals.

    The 2014 IPCC Assessment expresses doubt that the global surface temperature increase will remain within the 2 °C target without deploying risky carbon-capturing or solar radiation-deflecting technologies. New behavioural research suggests that, if the IPCC is right, citizens and policymakers will support such risk-taking.
