In the UNFCCC international climate negotiations, “ambition” refers to countries’ collective will to cut greenhouse gas (GHG) emissions enough to keep global average temperature increase below 2°C. While most countries have made international pledges to limit GHG emissions, these pledges are not “ambitious” enough to add up to the GHG cuts needed to meet the 2°C temperature goal. That’s why many groups are calling on parties in Doha to step up their commitments. Equally important, though, is ensuring that countries are effective in implementing domestic policies that meet – or exceed – the international commitments they have made already.
What Makes for an Effective Domestic Climate Policy?
The “implementation deficit” – a difference between the expected and actual amount of emissions reductions of an enacted policy—stems from a lack of complete implementation of a climate policy. This kind of “deficit” is well documented in a number of policy sectors, with significant implications for the countries’ abilities to meet GHG-reduction targets. Conversely, when climate policies are effectively implemented, they demonstrate that mitigation actions can work, in turn encouraging other countries to adopt similar policies and actions.
The effectiveness of any policy depends on several key factors, including:
