Progress on the climate front does not depend solely on what our governments decide. The Parliaments play a crucial role. Domestic legislation is needed in order to establish the institutional frameworks and policies to measure, report, verify, and manage emissions. It is one thing to pass legislation and another to implement it. The role of legislators does not end when legislation is passed. Legislators’ have an important role in oversight of governments and in approving national budgets that provide funds needed for implementing climate legislation. At this Side Event we will explore the progress with climate related legislation on the basis of a recent report published by the GLOBE Climate Legislation Study, A Review of Climate Change Legislation in 99 Countries. This report is the product of an ongoing co-operation between GLOBE International, The Inter-Parliamentary Union (IPU) and the Grantham Research Institute on Climate Change and the Environment at the London School of Economics.
