All OECD countries are addressing climate change and its effects in some way, as they are some of the largest emitters of greenhouse gases and have the resources and capabilities to take action. To address climate change, OECD countries have implemented a range of policies and initiatives aimed at reducing greenhouse gas emissions and transitioning to low-carbon, sustainable economies. These efforts can include setting emissions reduction targets, investing in low-carbon technologies, promoting sustainable land use practices, and engaging in international climate negotiations. In addition, many OECD countries are also working to adapt to the impacts of climate change that are already happening or are expected to occur. This can include measures such as improving the resilience of infrastructure and protecting vulnerable communities and ecosystems.
