The relationship between the EU and Kazakhstan has historically been dominated by trade in oil and natural gas. However, the EU’s Green Deal and commitment to reach climate-neutrality by 2050 means that the bloc is slowly but surely reducing foreign non-renewable energy imports. Moreover, energy transitions and halting climate change have become global developments and commitments, enshrined in the Paris Agreement on Climate Change. Fossil-endowed Kazakhstan has pledged to be carbon neutral in 2060, but its transition policies must pick up speed. Meanwhile, the EU is embarking on a reinvigorated energy diplomacy agenda that should encourage and support other countries to transition towards renewable energy production, export and domestic consumption. This policy brief explores what tools the EU could use to support such transitions and what Kazakhstan could benefit from most. It considers the link with geopolitics and competitiveness and how to overcome obstacles for EU-Kazakhstani renewable energy cooperation, whilst also offering recommendations as to next steps forward.
