Lastly, changes in end-use technology can reduce energy demand. For instance a well-insulated house emits less than a poorly-insulated house. [89]: 119 Mitigation options that reduce demand for products or services help people make personal choices to reduce their carbon footprint. This could be in their choice of transport or food.
Climate risk insurance is a type of insurance designed to mitigate the financial and other risk associated with climate change, especially phenomena like extreme weather. [ 22 ] [ 23 ] [ 24 ] The insurance is often treated as a type of insurance needed for improving the climate resilience of poor and developing communities.
Climate change mitigation scenarios are possible futures in which global warming is reduced by deliberate actions, such as a comprehensive switch to energy sources other than fossil fuels. These are actions that minimize emissions so atmospheric greenhouse gas concentrations are stabilized at levels that restrict the adverse consequences of ...
Rapid, sustained, and effective mitigation based on coordinated global and regional action is required to avoid dangerous climate change regardless of how it is defined. Weaker targets for 2020 increase the risk of crossing tipping points and make the task of meeting 2050 targets more difficult.
Climate change can be mitigated by reducing the rate at which greenhouse gases are emitted into the atmosphere, and by increasing the rate at which carbon dioxide is removed from the atmosphere. [270] To limit global warming to less than 1.5 °C global greenhouse gas emissions needs to be net-zero by 2050, or by 2070 with a 2 °C target. [271]
As of 2021 the remaining carbon budget for a 50-50 chance of staying below 1.5 degrees of warming is 460 bn tonnes of CO 2 or 11 + 1 ⁄ 2 years at 2020 emission rates. [14] Global average greenhouse gas per person per year in the late 2010s was about 7 tonnes [15] – including 0.7 tonnes CO 2 eq food, 1.1 tonnes from the home, and 0.8 tonnes from transport. [16]
Environmental mitigation can be defined in various ways depending on the institutions and countries where the term is applied, or on the framework that is used to guide mitigation. For example, it may be defined as the process by which measures to avoid, minimise, or compensate for adverse impacts on the environment are applied. [1]
5 May: The United Nations Environment Programme's Global Methane Assessment forecast that human-caused methane emissions can be reduced by up to 45 percent this decade and would avoid nearly 0.3 °C of global warming by 2045, and can be consistent with keeping the 1.5˚C goal for the century. [134]
